WTWWW - Not so lonely survivors

< Previous Masterlist

Note: Sorry this is comming out a week late. Also, just so you guys know, the next chapter will be posted 25 September.

Summary: Fueled by gratitude, it is time to pay back for his generosity. That means a whole lot of work for the foreseeable future. But, with a bit of help, it ends up a way better experience.

Chapter 4 – Working 9 to 5

The world is clear, sharp.

Glasses sit on your nose. Your new glasses. Ones that Senku made for you.

It still makes your heart race and cheeks warm.

A good motivation to deliver the best of your capabilities and build the best house of this era.

But that requires quite a lot of things.

First, materials. Like the logs that pile up nicely on one side of the site. Except, that is less than half of what you will actually need.

Maybe you shouldn't make it a log cabin...

No, the blueprint is done. The work has started.

No backing down.

Though with one look at the pile of logs, it's obvious you'll need help and more ways to lift the logs.

Dammit.

You sit down, thinking about the issues you've put off until now.

A crane would make this so much easier...

Well, I could try making a pulley.

You look at the clear sky above you. Nothing in sight that the pulley could hang from.

Fuck.

Scratching your head an idea strikes you. A temporary solution to your struggles that should work until the building gets too high for the mechanism.

Still a pulley, but attached to a log that you can drive into the ground, and if you build supports around it, it shouldn't topple over.

Yeah, that could work.

Though I do want to try something else first.

You drag one of the logs over, tools spread on the floor around you.

It's time to see if you can even work the wood with these tools.

Step one: debarking the log. Easy peasy, the bark peels nicely with the help of your trusty knife, the work done in almost no time at all.

Step two: actually shaping the log.

This takes a bit more time. A lot more actually.

You start by splitting the whole log in half length-wise, so that it will lay on the ground nicely. Making this piece a part of the foundation… if it works out.

The log is ready. Well, technically, two sides of the foundation are ready.

Now time for the actual test.

The second log get debarked, thankfully with the occasional rain showers the bark doesn't fully adhere to the trees. If you did this in autumn, this would have been a lot harder.

Now, the part that's making you nervous.

The way you want to connect the logs is rather simple, always carving a half moon grooves into a log. A smaller one on the full length of it, and two that go in the corners of the build. That way it will snugly sit on top of the other logs. This is called a swedish cope.

You put the log up to the ready halves, marking with charcoal where everything should be. Since this is the foundation, only the two, side grooves need to be done for now.

Then, it's time to carve.

Kaseki has been kind enough as to gift you his old set of tools, well worn but still perfectly sharp. And to your surprise, that included not only the chisel you'd asked for, but a few different kinds of chisels too. Ones that will help immensely right now.

You drag the curved blade over the log, again and again.

The wood doesn't give easy, but you are able to slowly carve away the unwanted material. Your arms burn before you even finish the first one. Fingers almost numb due to the grip you have on the chisel.

When you move away to take a look at your work, a pop in your back stops you for a moment. Pain shooting all over for a second.

How long have I been carving?

The sun is high in the sky when you look up. Hours must have passed, maybe two or three.

Looking down, you freeze. Heart hammering in your throat.

A mop of blonde hair is squatting right next to you. A blue dress even brushing over your skin every few seconds.

Suika.

It's just Suika.

You breathe in deep, letting the weight of it settle in your lungs before exhaling.

"How long have you been here?"

Suika looks up at you before chirping. "Since you started doing this!"

Great, either she is some kind of little ninja, or you concentrated so hard the world could burn and you wouldn't notice.

You don't know which is worse.

But neither would be good for your heart.

You shake it off.

"Wanna see something cool?"

Suika nods the same way she always does, almost toppling over from the motion.

Looking down at the log, you pray to anyone who would listen for this to work. Lifting the corner you just carved, you shuffle so it hovers above the half log from earlier.

Slowly, you lower it, letting it settle together.

With a soft huff, the wood sits. The groove deep enough that both logs can touch the ground, leaving no gap between the logs themselves.

You stand there, staring.

It fits.

It actually fits.

I can do this!

You pump your fist in the air.

"Fu-"

You catch yourself. Suika is standing right in next to you.

"Frick yeah..."

It comes out way lamer, almost all of the triumph replaced by the embarrassment of almost swearing in front of this sweet child.

She doesn't notice any of this.

"Yaaaay!" She squeals. Happy on your behalf. Even if not fully understanding the gravity of this moment.

You sigh, letting go of the negative emotions. Bending down to pick Suika up into your arms. As soon as she is secured, you start spinning the two of you around.

"I can do it!"

"You can do it!"

The two of you chant.

This goes on for a moment, before you both get dizzy.

Slowly, you lower Suika back on the ground, looking back at the log pile. Calculations run through your head, the time this will all take to finish.

It's taken a few days to gather this much wood. It will take even longer to carve everything into shape. And that's not even including the rooms and furniture. Or the fireplace.

"If only I had some help…"

The sound surprises you. That wasn't meant to be said out loud.

"Kohaku could help. She carries heavy stuff all the time! She's super strong!"

Suika chimes in.

You look at her, already moving to pat her head.

"Yeah, Kohaku would be great help. I'm just not sure if she has the time. You know, with all that training she's doing."

Suika wonders for a moment.

"Hmmm. She always complains that Kinro and Ginro are lacking in strength."

It clicks. A lightbulb flickering on inside your head.

"That's it Suika! Thank you!"

You lean down to look her in the eyes, grinning ear to ear.

"You might have just solved this problem!"

Soon enough, the sounds of training can be heard. Series of quick wooden thunks ring out through the air. Each hit sharp enough to ring in your ears painfully.

"Hey-"

*Thunk*

"AHHHH!"

Out of the corner of your eye you watch Ginro fall on his ass, his eyes wide and a finger pointing at you before calming down.

But you mostly focus on the wooden sword aimed at you. Kohaku holding it on the other side, her expression smoothing out when she notices it's only you.

You put a finger on the tip of the blade, slowly pushing it away. Kohaku let's her arm drop, the wooden prop moving away with it.

"How did you get here so silently?"

She asks, looking you over.

You raise a brow.

"I just walked? You guys were too loud."

Kohaku scoffs a little, looking over your legs again. A small smile appears on her face, as if she knows something you don't.

"Well, anyways, what brings you here?"

"I have a favor to ask. More of a mutually beneficial deal."

Kohaku's eyebrows crease. A look of distrust appearing after those words.

"Listen first, then you can decide. I'm not like Senku to skimp out on the details."

She lightens up at that, though only slightly.

"I need materials, wooden logs, for something I'm making. I need to cut down a whole lot, as well as moving them to the building site. That’s where I need help, as you can see, not much strength in this body to do this quickly enough."

You flex your arms, showing off the slight bit of muscles you do have, clearly not enough to replace a full construction crew, or a lumberjack.

Kohaku looks at you, nodding slightly in both an understanding and to urge you to go on.

"On the other hand. I believe this could help you with training, either yourself or the brothers."

You point at the two boys currently sitting on the ground, panting slightly. Both looking worse for wear in the middle of their training regiment.

"Look, clearly they need to build up their strength and stamina. Cutting and hauling logs could help with that. I don't even need it to be done in a day, meaning this could be their warm up before you all delve into combat training?"

Kohaku looks at the two boys. A hand on her hip. She sighs, seeing what you see. But she still looks a little torn.

"I could sweeten the pot a little."

"What?"

"Oh, uh, I can make this deal even better for you? I could also show you some stretching exercises I know."

Kohaku thinks for a moment, looking a little suspicious before seemingly coming to an answer.

"Show me something now and I'll see."

You nod, stopping when a thought hits you.

"First, I need to see your range of motion."

Kohaku looks at you for a moment before starting to move. While her moves are graceful, it's the exact opposite of what you meant.

"Wait, wait!"

Kohaku stops mid-motion.

"I just need to see how far your limbs move. Look."

You extend your arm towards her, letting your elbow stretch past normal limitations. Ginro and Kinro look sick, while Kohaku looks fascinated. She moves closer, inspecting your arm.

"Wow, you could teach me that?"

"Not really, not unless you can already do something similar. This is genetic, and honestly, it's not as cool as it might look."

Kohaku stands next to you, extending her arm. Everything locks into place, no hypermobility to be seen.

Which, for Kohaku, is great but for the sake of showing her stretches, it does throw a slight wrench in your plans.

"Alright, give me a moment. There are stretches I can show you, I just need to filter out the ones that will probably not help you."

For a moment nobody moves, except Kohaku looking at her own arms as if they betrayed her.

"Okay! So…"

You start showing her how to properly stretch, some exercises she already knows, some deepening her knowledge.

"That's about it for now? We're kind of limited to just using our body, we could do more if we had the equipment. But honestly, this should be enough."

You lend Kohaku a hand, intending on helping her up.

So you don't expect to be pulled down instead.

"Whoa!"

Kohaku moves, stabilizing you and getting up at the same time.

"Thanks! Remind me not to try helping someone up."

You remark while Kohaku stays silent, her scrutinizing gaze sweeping over you. She walks around you, pulling on your arm to look better at the muscles.

"Perhaps... you could also get some training."

She says and you gape at her. Not liking where this is going.

"Me? I don't have time..."

"Well, if you're going to be using the logs we'll get you, you'll need strength. More than you have right now. But you do seem to be on a good track."

She touches your forearm, and you flex the muscle on reflex. Her fingers move along the skin, nodding to herself.

"Right, it's clear that you are a master of your crafts. Maybe not as much as Kaseki, but not far behind either."

Your face goes up in flames.

"Wh-what?"

You squeak, the sound high and quick.

"Okay, I accept your deal, as long as you'll join us for the process."

Kohaku's tone leaves no room for argument. All you can do is nod silently.

She turns to the brothers, getting straight back into training.

You turn, walking off into the forest. Needing both a moment to yourself and to gather some vines for rope.

The next few hours are productive. You clear your mind, letting the silence around you settle. Ignoring the occasional voices coming from the direction where everyone is.

Your arms are full of vines by the time you return.

Walking past the furnaces, seeing Kaseki stand there, a pipe in his hands, Molten glass at the end of it.

So they got him in the end.

Wait?!

You do a double take. The red hot glass still attached to the pipe, only a different shape now than the blob you saw before.

The vines fall to the floor as you make a beeline towards the thing you've not yet tried.

Hands wrap around your waist, and a body steps in front of you. Chrome is standing still, hands spread wide.

"Not one more step."

Senku's normally monotone voice is tinted with a slight panic. His hands hold tight, feet planted firmly on the ground.

Then it hits you.

This is what they needed Kaseki for?

A slight bit of hurt creeps in with that realization. Your body relaxing, letting Senku cautiously let go of you.

The places he touched staying warm.

"Why didn't you ask me to try?"

You let the feelings show in your tone.

Senku sighs, while Chrome looks a little awkward.

"I know you want to try glassblowing. BUT, I can't let you learn and waste precious materials on things we don't need."

A bit of shame tries crawling in, knowing perfectly well that Senku is right. You probably would have made full sets of bowl, glasses and decorations.

But that doesn't mean he should have hid it from you.

You pout, turning your face away from them.

Senku moves closer, letting his voice drop so only you can hear.

"Don't worry, once we have stocked up more than we can use, I'll let you go wild. Think of it as a reward for all the hard work."

His tone is gentle, almost coaxing. The exact tone he learned works on you every time.

You huff, letting the pout fall off of your face.

"Fine, you better keep your word."

"You know I do."

"Yeah, I know."

Senku slowly relaxes, the worry bleeding out of his expression. So you let yourself relax too.

Looking past Senku, you find Kaseki looking at the two of you, a weird glint in his eye. You shrug it of, calling out to him.

"Kaseki, could you come to the fenced are after you're done here? For a craft circle?"

He grins in response, nodding happily.

Looking at Senku and Chrome, you raise a hand, waving.

"See you guys at the campfire."

They wave back, Senku back to normal, meanwhile Chrome keeps looking between the two of you, eyebrows raised almost up to his hairline.

The vines are sprawled on the ground. You take your time gathering them, seeing no reason to rush.

You put them down at the building site, keeping a few that you start working on. Unwinding and braiding it into a rope.

The process is slow, careful to not let the rope slack or fray.

Kaseki comes after a while, looking giddy. Thankfully his clothes seem mostly intact despite the obvious excitement.

The two of you launch into a new conversation. Kaseki relaying the new task Senku set up – a lab. Which is why there is a need for glassblowing.

This immediately brings you to what you wanted to discuss.

"I need your help, if possible."

Kaseki looks up, a complete opposite of how he looked at you when you first approached him.

"I'm already building a house. For Senku and Chrome. As a gift. I'll have some help with the materials, but I also need help with shaping everything so that I can finish it soon."

Kaseki thinks for a moment, his chin between his fingers.

"So you're proposing we help each other out? Building both the lab and the house together?"

"Yep."

He grins, arm stretching toward you.

"Deal! Oh this will be fun! I haven't built with someone for a very long time!"

You smile back at him, heart swelling with joy. It sits there, warming you up from the inside.

Next, the blueprints for the house are laying between you. Both of you going over what needs to be done. You even show Kaseki the base you successfully made.

"See? I flattened this side and made these groves, so it sits nicely, the next log will be shaped similar, just more curvy rather than flat!"

Your hands move, pointing all over the log.

Kaseki pats you on the head.

"Amazing!"

That stops you. Freezing you in place. Face going blank.

Amazing!

A dopey smile stretches on your face, the warm feeling inside intensifying.

You proceed to ramble on, spurred on by the praise. Pointing where the lab could go, the plan for the rooms, the way to do windows for both buildings. And the idea of making your own home.

Kaseki throws in his ideas, improving on some ideas, and learning why some wouldn't work.

The sun is setting by the time the conversation ends.

"Oh, my. Look at the time."

Kaseki says, his tone falling as the day ends.

You keep smiling, knowing this doesn't have to be the end.

"How about you join us all? After all, you are by now a sort of member of the Kingdom of Science, no?"

His gaze finds yours, an eyebrow raising in question.

"We sit and talk by a campfire in the evening. We also eat dinner. We'd just have to not talk about the house and we could continue brainstorming."

"Brainstorming?"

"Oh, it's like what we just did. Go over ideas, decide what works and what doesn't."

"I like that."

You smile, offering Kaseki a hand.

"Let's go."

He smiles back, letting you lead him to the fire.

Senku just finished lighting it up, Chrome already putting fish nearby to cook.

In the distance Kohaku, Ginro and Kinro are walking back as well.

Suika is already sitting there, instructing Chrome to put the fish a bit closer to the fire.

Behind you, Kaseki's breath hitches. You turn to look, seeing his wide eyes take in the sight. His mouth and hands trembling, eyes gaining a wet sheen.

"It's been a while since I spent time with others like this."

"Well, from now on, you can spend however much time you want with us. You're part of the team now."

He smiles, his cheeks rosy and wet. Few tears managing to fall. His feet move faster, no longer moving behind you, instead walking next to you.

The evening is warm. Both the temperature, and the way the group acts. The small quips, random jokes, and future plans.

It all leads into a very peaceful night before work intensifies.

And just like the deals were made, they are carried out.

Kohaku steals your time in the morning. The whole group stretches, then begins gathering the wood. Axes swing through the air, arms vibrate with each hit, and logs hit the ground.

After a few piles form, each prepared for a specific person, the final part of this workout starts. The hauling.

Kohaku takes the log, resting it on her shoulder and bicep. Her steps not affected in the least. Kinro mirrors the move, though the strain is visible with his slightly wobbly steps. Ginro whines before grabbing a log and pulling it onto his arms, carrying it close to his chest despite having to peek over the thing to even see. You, on the other hand, pull it with you, striking the axe into the wood and letting it mostly drag on the ground.

Despite the struggle, you have to admit that it is easier than it was the first time. But you also know that your arms will hurt all the same.

A few trips later, Kohaku and the brothers depart for combat training. And in their place, Kaseki joins you.

He spent the morning blowing glass that needs to cool down now. So in the meantime, the two of you work on the buildings. Shaping logs, smoothing sharp spots. Then moving onto building a frame for the lab.

Continuing into the evening when you both call it quits. Legs feeling like jelly, arms feeling even worse.

And still, the work continues. By the campfire, as everyone talks and laughs, you work on making rope, crocheting and knitting.

This continues the next day. Forming a cycle that lasts about two weeks.

The only exception to the stable routine has been a heist. One night, you and Kaseki quietly melted some glass, making window panes for the house.

You had to wait for a night where the boys have been way too tired to wake up in the middle of the night. Not wanting to risk them waking up and seeing any of this.

Courtesy of Kohaku, who agreed to your idea to have the boys join the training for a day. You used the guise of them helping with the lab construction to get them to agree.

You have never seen Kohaku laugh that much. Though, your stomach and cheeks also hurt for the rest of the day. A wide grin sitting on your face, earning a scowl from Senku anytime your gazes met.

Still seeing flashes of the image of Senku folding under the weight of the log for his own lab.

This was also done in a sort of revenge for working you all to the bone, while he enjoyed some peace these few days.

All the way until you proudly stood in front of the house. Fully finished, even with the necessary furniture.

Of course, the lab is also a really nice piece of work. But that is a collaboration between you and Kaseki.

This, this is your work. Done with help. But under your guidance of the entire thing.

You even gained something too. Experience, and mainly, strength. You stand a bit straighter, finally feeling the support of muscles keeping your joints more in place.

Now, the only thing left to do, is to show it all to its new owners.

The lab is first.

Senku is, of course, enchanted with the place.

Shelves lined with glassware all ready for his laboratory needs cover the right wall. The left side has more shelves, this time filled with clayware. A thick glass slab rests on top of a table for a sterile working surface – as well as being fire resistant.

You even created a wooden window of sorts, meant for airing out the space. There are small openings by the roof, to keep the air clean, but this is for the moments when too much happens at once. Though there is also the open doorway to help with that. Only covered by two fabric curtains instead of a proper door.

Chrome is also fascinated by it all, but his lack of proper knowledge holds him back from enjoying it as much.

"This is so BAD!"

Chrome gushes about the place, turning to Senku and asking about things.

You give them about five minutes to enjoy the space. In the meantime instructing Kaseki to take down the fencing.

As soon as Kaseki comes back, you clear your throat, catching attention of the two boys.

"There is one more thing that you need to see."

You and Kaseki step away from each other, revealing the building.

"Your new home."

You beam, arm moving to show your creation.

"Now, this way."

Senku's mouth falls open a fraction. As always, a reserved reaction. On the other hand, Chrome is completely open about everything. His jaw hanging open so wide a bird could comfortably fly inside.

Snickering, you turn and walk toward the house.

Actual doors keep the space closed, series of windows let in light. You made sure the windows could also be opened for some fresh air.

The door leads into a central room, a fireplace situated at the far wall with chairs placed in front of it. There are two doors on the left side and two on the right, leading into four rooms.

Three of those are bedrooms, the last one you kept empty. That one will be for the boys to use however they like.

Two of the bedrooms have an actual bed – a wooden frame, straw, two blankets and a pillow.

The third one only has a frame. The rest still in the process of being made.  

The boys walk through the house. Chrome loudly expressing his happiness. Senku quietly observing the space, throwing glances your way. His eyes, softer than usual, speak volumes of his gratitude.

When they reach the third door, Chrome turns to you.

"Why is there a third bed? Will you be living here too?"

He raises an eyebrow.

"Nah, that's for the anticipated return of someone. Don't worry about it too much."

Senku nods at the words. But Chrome is even more confused, though by now he knows that you probably won't answer.

Then it's time for the final room, the empty space. Both turn to you, silently questioning. You shrug.

"You decide, it's your house now."

At that, Chrome grins. He turns to you fully before patting you on the back. As you see him from up close, you can see him hiding tears.

Senku looks from beside the door, a small smile on his face before he mouths 'thank you'.

You smile wide, also feeling the slight sting of tears. It all feels so warm, your chest tightens. Satisfaction meeting praise.

But you won't let your ego grow bigger than this. Even though you did manage to very clearly catch Senku off guard.

When Chrome moves into a room he claims as his, Senku moves closer. He stands side by side with you, looking over the whole space.

"Good job, Wild Card."

You grin even wider.

"Better than that wattle house before, right?"

It comes out before you can think about it.

"What?"

"Huh?"

Pairing: Senku x Reader

Word Count: 2755

Tags: Fluff, No Petrification Beam, Modern AU, Domestic Bliss, You and Senku have a JOB.

Description: After a miserable day of overtime and a commute from hell, the last thing you expect is to come home to a warm meal, a clean apartment, and Senku Ishigami waiting for you. Of course, he insists it’s just the logical solution to your exhaustion. You know better.

Tags: @v0ctin hehe, I remember telling you in a comment section that I’d write this, so… hi… (⁎⁍̴̆Ɛ⁍̴̆⁎)

And @viethealexis because, uh, imagine this as a pregame to the angst I’m about to whip up.

· · ─ ·✶· ─ · ·

By the time your car lurched forward another six feet, you were convinced the city had collectively forgotten how roads worked.

The navigation app had long since abandoned any optimism. What had begun as a thirty-minute drive home had quietly crept past an hour, then another twenty minutes, each reroute sending you through streets that were somehow even worse than the last. Construction cones funneled four lanes into one. An ambulance screamed past on the opposite side of the divider. A bus blocked an intersection because someone had tried squeezing through a yellow light that very obviously wasn't going to happen.

You let your forehead fall against the steering wheel for exactly three seconds before the driver behind you honked.

"...Yeah, yeah."

The light turned green.

Nobody moved.

You exhaled through your nose.

Your manager's voice still echoed somewhere in the back of your mind.

"Sorry, I know it's last minute."

It was always last minute—The report had needed revisions, but revisions needed approval, and approval needed more revisions. By the end of it, everyone else had gone home while you remained under sterile white office lights that made every minute feel twice as long.

You'd texted Senku during one of the five-minute breaks you managed to steal.

Me: bruh

Me: stuck with overtime AGAIN

His reply had come almost immediately.

Senku: LMFAO.

Senku: Sucks to be you.

That had been the entire conversation.

Which, admittedly, was fairly normal for him.

When your apartment building finally came into view, your grip loosened around the steering wheel for what felt like the first time all evening.

Home.

You could already picture it: After you took your shoes off, you’d microwave whatever leftovers happened to exist. After that? Maybe take a shower. Maybe not. Then, collapse on the couch, wake up in the morning, and do it all again.

You climbed the stairs slower than usual, fishing your keys out of your bag more by muscle memory than conscious thought. Your shoulders protested every movement. Even the strap of your work bag felt heavier than it had this morning.

The lock clicked.

You pushed the door open, only to pause when an unfamiliar warmth greeted you from inside. The apartment smelled... good.

And it wasn’t from the artificial sweetness of a candle or the freshness of an air freshener, but something far more unexpected—an actual meal being prepared. The scent of simmering spices and freshly cooked food filled the room, a small but immediate reminder that, somehow, someone had thought ahead for you.

Your eyes drifted toward the kitchen, "...Senku?"

Without looking up from the cutting board, he answered, "You made it."

You stared.

He was wearing the hoodie he'd stolen back from you three weeks ago because technically it had originally belonged to him. Sleeves shoved halfway to his elbows, a kitchen towel thrown over one shoulder, he was methodically slicing green onions with the kind of concentration most people reserved for assembling IKEA furniture.

Several grocery bags sat folded neatly on the counter.

Your drying rack had dishes on it.

Your sink...

"...Why is my sink empty?"

He didn’t around to response, his attention still elsewhere, "Hm?"

"My sink,” you repeated.

"It has no dishes,” he chuckled lightly.

"I noticed."

“Well,” Senku stood up straight, his eyes landing on you. “Obviously, I washed them.”

You blinked, "You... washed my dishes."

"I know. Crazy." He swept the chopped onions into a bowl, "I was aiming for unprecedented."

“Uh huh,” You slowly set your bag on the floor. "So, you came here to do chores for me?"

“Duh,” He shrugged like it was self-explanatory, "This morning you told me your boss volunteered your evening."

"My boss didn't—"

"He did."

"..."

"You just weren't exactly given the option to decline," he huffed, though there was a trace of amusement in his voice. "Better to keep the workplace peace than have your boss decide you're suddenly their least favorite employee."

"...Fair," you muttered, setting your bag on the kitchen counter.

He reached over to lower the heat beneath the saucepan, giving it a brief stir before continuing. "I got home around four from the lab."

"Mhm." You took a seat at the table, watching him with an increasingly curious, fond gaze as he moved around your kitchen with the ease of someone who had done it before.

"The news said a water main burst downtown."

"Mhm."

"They listed every road closure." He picked up the wooden spatula and began moving it through the pan in slow, absentminded circles.

"Mhm."

"I checked traffic on your usual route home," he continued, a slight edge of exasperation entering his voice, "after you didn't answer. So I figured you definitely got caught up in it."

You tilted your head, a small smile crossing your lips. "Wow, really? All that deduction work for me?"

"Exactly." He gave the soup another stir, glancing at you from the corner of his eye. "So I estimated how long it'd take you to get back, realized I had ample time to start a few quick chores."

"..."

"You would've gotten here tired." He shrugged, but his tone softened. "Figured I might as well make things a little easier for you. So I came over."

The answer was delivered with such little ceremony that it almost made you smile more than anything else he'd said.

"So... you came over?" you repeated, quieter this time.

"Mhm." Senku turned off the stove once he deemed whatever he was cooking sufficiently finished and moved the pan onto an unused burner. He wiped his hands on the kitchen towel before turning toward the refrigerator. "Speaking of which, I bought your groceries for the next week. Besides what I used to make dinner."

"How sweet," you hummed. "How'd you know what to buy? Should I pay you back?"

Senku paused halfway through opening the fridge and looked over his shoulder, one eyebrow raised. "Obviously not. I'm your partner." There was a faint smile tugging at the corner of his mouth. "Plus, eventually we're gonna live together anyway. Consider this a trial run."

He crouched to inspect the lower shelves, continuing, "As for how I knew, I just guessed based on your pretty meager fridge situation."

"Ouch." You chuckled.

"There really wasn't much." He pulled out two sodas, then grabbed two glasses and filled them with iced water. He held one of the empty glasses toward you like an accusation. "You need to get better at stocking your fridge. Seriously. What were you gonna eat tonight? Ice?"

"Hey!" You pointed right back at him. "I've been plenty busy. And besides, remember when you were spending thirteen hours in the lab to finalize some report? I don't think you should be scolding me for my work ethic."

"Tch." Senku cracked open his soda, clicking his tongue against his teeth. He gave you a sideways look, but the small smile threatening at the corner of his mouth made it obvious he wasn't actually annoyed. "Enough of that. Just be happy I left your house cleaner than I found it."

You smiled, resting your chin against your hand. "I am."

His eyes flicked toward you.

"...Good."

It was such a small word, almost lost beneath the hiss of carbonation and the quiet hum of the refrigerator, but the way he said it made your chest feel strangely warm.

Then, as if realizing he'd allowed himself to sound too sincere, he turned back toward the kitchen.

"Now, eat before I start charging you for all this labor."

You laughed. "You just said I didn't have to pay you back."

"That was before you started getting sentimental,” he frowned.

"I said one word.”

"Exactly!" He grinned, somehow managing to balance two plates in his hands as he carried them over to the table. He set one neatly in front of you before placing the other beside it, then immediately turned on his heel to retrieve the drinks. "And that's all it took."

You took a moment to look around the apartment while he busied himself with the beverages.

It was strange seeing everything so orderly, especially knowing he'd been the one to put it that way; He’d actually taken the time to straighten up. The coffee table had been cleared of the usual assortment of receipts, cups, and whatever else had accumulated there throughout the week, while the stack of unopened mail by the door had been sorted into something resembling an orderly pile rather than the precarious tower it had been threatening to become.

Even the smaller things had been tended to.

The blanket you’d left half-sprawled across the couch had been folded neatly over the armrest, and the curtains had been drawn back just enough to let the evening air circulate through the apartment. Nothing had been rearranged or scrubbed to the point of feeling unfamiliar; he’d simply put things back into place, quietly restoring some order to the space you’d been too exhausted to notice had fallen into disarray.

"...Senku,” you leaned up to face him as he came walking back.

"What?" Senku placed a glass of water and a soda in front of you before sliding into the chair beside yours.

"...This is weird." You gave him a tired, almost disbelieving look as you reached for the water.

He glanced over at you, one eyebrow lifting. "Weird?"

"You."

He pointed at himself, a faint grin tugging at the corner of his mouth. "Me?"

"You're acting..."

"What?"

"...Domesticated." You visibly cringed at the word.

Senku snorted. "Hah. Don't insult me."

"I'm serious." You pointed your fork at him before taking a bite of what he'd made, chewing thoughtfully as you watched him.

He leaned back in his chair, looking far too amused by your accusation. "You make it sound like I got adopted."

"You practically survive on instant noodles," you said slowly, making a conscious effort not to speak with your mouth full.

"I survive on efficiency."

"You own exactly one frying pan."

"I own the necessary frying pan."

"You once told me dishes were optional." You lowered your fork, staring at him in genuine disbelief. "And then you spent ten minutes trying to explain, with physics, how you could theoretically avoid touching the surface of a plate while eating so you wouldn't have to wash it."

"Hey." His protest lacked any real conviction, especially with the way he was trying not to smile. "I know you enjoyed that tirade."

"I was fascinated by how committed you were to being ridiculous."

"Same difference."

"Okay, but now you're in my kitchen making actual food." You tapped the edge of his plate with your fork, glancing between him and the meal he'd prepared. "That's what I don't understand."

Senku frowned slightly, though there was more amusement than annoyance in it. "That's because your kitchen has more utensils."

"..."

"And seasoning."

"..."

"And oils."

"..."

He caught your stare and reached across the small space between you, tapping your forehead lightly with his finger. "Don't look at me like that. It's unbecoming."

You rubbed your forehead, fighting a smile.

"You'd be amazed what becomes possible with a few more variables."

That got you.

A laugh slipped out before you even realized you still had enough energy left for one.

Senku's expression softened immediately, satisfaction flickering across his face. "There it is."

"What?"

"That." His smile turned teasing again. "You stopped looking like you wanted to fistfight public infrastructure."

"I still do."

"Valid."

Your laugh faded into a sigh, the sound quieter this time. It wasn't dramatic or particularly deliberate; it was simply the weight of the entire day finally making itself known now that you were somewhere safe enough to let it. Your shoulders sank, and you stared down at your plate for a moment, appetite returning only because you no longer had to think about where your next task was coming from.

Senku didn't comment on it.

He simply nudged the soda a little closer to you, "Eat."

You glanced at him, "...You know, for someone who claims to be all about efficiency, you spend a suspicious amount of time taking care of me."

He shrugged, picking up his own fork. "You're inefficient when you're exhausted."

“Seriously?” You narrowed your eyes, "That's your excuse?"

"For now." The corner of his mouth lifted. "...Got a better one?"

You looked at him for a moment, then smiled despite yourself, "No."

"Thought so."

By the time you finished eating, the plates were nearly spotless, which you decided was a decent enough indication that Senku's cooking had been a success. You carried everything over to the sink before he could stop you, turning on the faucet while he gathered the remaining dishes.

"I'll wash," you said, reaching for the sponge.

"Then I'll dry."

"And put them away?"

"Obviously."

You glanced over your shoulder at him. "You're getting awfully comfortable here."

"Somebody's gotta keep this place functional."

You rolled your eyes, but you were smiling as you worked. It settled into an easy rhythm between you: you washed, he dried, and whatever you handed him disappeared neatly back into its proper place. There was something strangely satisfying about it, especially after the chaos of the rest of your day. No rushing, no checking the time, no one asking you for anything. Just the quiet clink of dishes and the sound of running water.

When a fork slipped from your hand and clattered onto the floor, you bent down to retrieve it.

The faucet suddenly went quiet.

Before you could straighten, arms slipped around your middle from behind.

You startled, letting out a small laugh as Senku pulled you back against him. His chin settled over your shoulder for a moment before he rested his face against the collar of your button-up, close enough that you could feel the warmth of his cheek against your neck.

"Senku?"

"Hm."

"What are you doing?"

"Making an observation."

You smiled, glancing down at his arms loosely wrapped around your waist. "And?"

He was quiet for a second.

"We should move in together."

You blinked, "...That's your grand observation?"

"Yeah." His voice was muffled against your collar, but you could hear the faint amusement in it. "Think about it. We could make being gross and domestic together way more efficient."

You laughed warmly, turning the faucet back on as you resumed rinsing the dishes, careful not to jostle him too much. "I'd like that."

His arms tightened slightly around you, "Good."

You let the moment linger before adding, "Although, if you moved into my apartment, it'd probably be easier for you."

"Why?"

"Less stuff to move."

He went quiet.

You grinned, feeling the urge to double down. "Actually, you could probably carry all of your belongings in one trip."

"How many times do I have to tell you—"

"Ten?" you interrupted. "Maybe eleven if we're counting your lab equipment?"

"You're really committed to this bit, huh?" He grumbled.

You laughed, and he gave your ribs a sudden squeeze.

You jumped.

"Senku!"

He finally let go, looking entirely too pleased with himself. "That'll teach you."

"That proves nothing."

"It proves you're ticklish."

"That's not relevant, like at all.

"Sure."

Before you could retaliate, he reached over and ruffled your hair, thoroughly ruining whatever order you'd managed to maintain after your shower.

"Hey!"

Senku was already walking away, "Clean up the rest, oh domestic equal of mine.”

You stared after him, incredulous, before looking down at the dish in your hands.

"...Ten belongings," you muttered.

From somewhere in the living room came his voice.

"Forty-two, actually."

You smiled to yourself and shook your head, turning back to the sink.

The apartment was still the same one you'd walked into hours ago—same walls, same furniture, same little messes you'd been meaning to deal with. But somehow, it felt different now. A little warmer. A little less like a place you simply returned to at the end of the day, and a little more like somewhere you could actually rest.

Maybe it was the dinner waiting for you when you got home.

Maybe it was the clean counters and folded blanket.

Or maybe it was just Senku, sitting in your living room like he belonged there, pretending that taking care of you was nothing more than a practical decision.

Either way, as the water ran over your hands and his quiet presence filled the room, you found yourself thinking that maybe moving in together wasn't such a crazy idea after all.

Synopsis: After he breaks up with you weeks ago, his friends force him to call you to repair your relationship. But your reunion goes wrong.

Note: This is my first smut fic so don't expect it to be perfect. 🥹

“It's better that we stay as friends.” Senku uttered those words to you weeks ago without a look of regret on his face. He expected you to break down right there and then when he saw your eyes were getting glossy.

But you didn't. Only a stray tear fell on your cheek.

“Okay, if you want to.” Were the only words you responded to him with. No argument, no question. Straight up agreement.

He felt strangely surprised. He hadn't taken into account that you would go along with it so easily. It doesn't mean he wanted you to talk him out of it, more so, he thought you would. Instead, you sucked it up without a single hesitation.

The poor boy even prepared a whole speech about it, in case you were going to try to convince him to stay. That shouldn't matter, though, right? Because you're both over now, back to the beginning. He wanted this.

Why is it still eating him up? Why is he the one getting all depressed about it?

Lately, he's been wallowing and overworking himself inside his laboratory for hours a day. Surviving on instant noodles, coffee, and chemical formulas.

His eye bags were darker and heavier than before, his hair wilder as if he hadn't taken care of himself ever since. And he's starting to feel his brain melting off due to the breaks he's been avoiding.

The disheveled man stared at his blank notes furiously, like it snitched on him and tapped his pen continuously against the cold desk in hopes he would be able to write something. Anything.

It didn't help that his four friends were looking at him with both concern and amusement.

“My, my~ it looks like the post-breakup symptoms are finally taking a toll on the logical scientist.” Gen was the first to break the silence in the sterile room with his teasing demeanor.

“That's not it, you mentalist, that's just my neurons trying to figure out what I'm supposed to do.” He deadpanned and kept glaring at the papers.

Chrome stepped beside Senku and looked over at his shoulder. “I don't know, these past weeks have been harsh for you. Even I can see it clear as day.” He added on and pointed to his notes. “See, usually there would be some badass hypotheses and equations written on it.”

Senku shook Chrome off him irritably and narrowed his eyes at the boy. “I'm perfectly capable. My thought process is only having a delay for now.”

A snap of a finger was heard across the lab. “Ha ha! It's been delayed for so long that I could believe she was your life support. You're still obviously yearning for your significant other, am I wrong?” Ryusui laughed and shouted with his bright and unmistakable grin.

“Yeah, you're wrong. I'm having an off day, what makes you think it's associated with my friend?” Senku scoffed and kept his stare away from the others.

“Then was every single day an off day to you, Senku?” Ukyo casually joined in with a gentle smile, in contrast to his words.

“Not you too.” He grumbled under his breath and rubbed his temples in an attempt to soothe his headache.

“We're just saying,” Ukyo walked over near Senku, with Ryusui and Gen following along. “You've been doing nothing but deny that you messed up.”

“I've been doing something,” Senku mumbled and ignored everyone's stare at him.

“What you're doing is mourning like you have a dead wife, Senku-chan.” Gen waved his hands in the air dramatically, making Senku exhale from the nuance.

“And besides that, you still haven't told us why you broke up with her,” Ryusui added, his playful expression shifting into something serious soon after. “You avoided talking to us about it, hell, you even avoided us. We only got the chance to talk to you today because we managed to access the lab before you.”

“Well, I don't know what you want me to do about it.” Senku dropped his pen on the desk with more force than necessary. “There's no point talking about something that ended already. I don't see the benefit.”

“But there's no point being so gloomy about it, though.” Chrome responded in slight confusion. “Aren't you contradicting yourself? ‘Cause there's also no benefit from it.”

He grew tense and uncomfortable at Chrome's comment. “Will you-”

“Enough, Senku,” Ryusui blurted out and interrupted him, taking a step toward the scientist. “You need to man up and tell us the reason why you left such a wonderful woman, it hurts to look at one of my friends being in this state.”

He took another step. “Everyone deserves happiness, and I'm the king of greed, damn it! If you won't tell us, we won't be able to help you out of your misery!” He pointed at Senku and yelled at him loud enough to make everyone else wince at the volume.

“Ryusui's right.” Ukyo joined in the heated conversation. “We want to help you with your situation. You're our friend, and it would be terrible of us to not take any action.” His tone was much calmer than Ryusui's.

Senku let out a deep exhale and finally swiveled the chair to face all of them, everyone could see how drained he was. “I was… just pathetic. So fucking pathetic and idiotic. I thought I couldn't be the boyfriend she deserved.” He said it bitterly and slumped his head down, narrowing his eyes at the floor in shame.

During your relationship with him, you were always the one initiating everything. Hugs, kisses, dates, you name it. And he barely reciprocated it, only doing so when he wasn't working or when he remembered he had a partner.

Truthfully, he's scared of commitment. He knows he's not the romantic type, but what makes it bad for him is that he doesn't try to change that. It felt wrong for him, the best he could do was show up.

He believed you shouldn't be with a guy like him. He left so you could get the chance to find someone better. Someone who could treat you the way he should've treated you.

“So that's what. I suspected she's been doing all the work since I only ever saw her cling to you more than you do to her.” Gen held a finger up to his chin. “Seems that your pride was mainly the reason for it. After all, your reputation is that of a calculating and rational man of science.”

“I know, I'm a joke,” He muttered and pressed his knuckle against his forehead. “I wish I could make amends to her.”

“Technically, you still can,” Gen responded and gestured to Senku's phone. “You're still friends with her, no? Call her and take her out, or do anything to make her be with you. Take that as a chance to apologize and hope you'll repair your sad, sad relationship.” He sang-song, yet his statement was still no joke; he genuinely wants to help Senku out.

“We are friends, but I haven't talked much to her, and neither did she. We only chatted when it was necessary. She probably hates to see me at all.” Senku brought his head back up and looked at them unconvincingly.

Ryusui went to Senku's side and took him by the shoulder. “Come on, you'll never know if you don't try. At least pass the ball to me instead, I'll treat her right.” His teasing actually gave Senku the push to grab his phone and scroll to your contacts.

“I'm gonna kill you after this.” He grumbled under his breath and gave one quick glare at Ryusui before proceeding to click on your name. He felt his heartstrings pull a little when he checked the recent messages, which were only about schedules and important topics. The last message was a week ago, with him ending the conversation with a ‘thank you’ — only expressing gratitude to you, of course.

Everyone else started chanting for him to press it. Tap. The phone buzzed with suspense. And to everyone's surprise, you answered sooner than expected. If they didn't know any better, they would assume you'd been waiting for this moment.

“Hello? Ishigami?” The other end projected your static voice. The phone was in speaker mode, so his friends were convinced it was really you and not some random person he called to clear himself out of the whole ex confrontation.

It did hurt to hear that you used his last name.

“Yo, yeah, it's me.” Senku greeted you awkwardly, making Ryusui and Gen facepalm at him, while the calmer ones looked at him in disbelief.

“I, uh…” He's never been this nervous before. Damn it, get a grip. He took a deep, shaky breath, with all the courage he could find. “I need some help here in my lab, mind if you come?” Senku mumbled as closely as he could get to the speaker so the others wouldn't hear him, but his bad luck is absolutely astonishing. The others heard it clearly — especially Ukyo — and it made their jaws drop at his poor excuse of a meet-up with your ex.

“Of course, what time should I go?” You responded quite enthusiastically. Or maybe that's just how you are whenever someone asks for help.

“As soon as possible.” He replied almost immediately.

“Okay then, I'm on my way.” The call ended once you assured him. This gave the others a sign to scream out horrifically at Senku.

Ryusui grasped both of his shoulders and shook him aggressively. “What the hell was that?! You're supposed to get back with her somewhere romantic! Maybe at a park or at my hotel, anywhere but here!” He barked.

“So much for the savior of humanity. He's completely dumb when it comes to love!” Gen crumbled onto the floor and placed a hand over his heart dramatically.

Ukyo seemed to have given up too, he ended up sitting on the floor with Gen with a flabbergasted expression. “That does it. It's approved that Senku is unreliable when it comes to these setups.”

And Chrome? Well, he dragged his feet to the exit of the lab. He grasped and turned the handle tiredly. “I'm out of here, this bullcrap is not worth it for me.” Just like that, he exited and left amidst the chaos of everything.

“I'm with him, I don't think I can do this one, sorry Senku.” Ukyo got up and trailed along where Chrome went, it ended up with the duo who were more horrified to follow pursuit as well.

“Wait, you fools! I don't know what to say anymore! If I messed up that badly, at least give me advice!” Senku raised a hand at them, trying to get them to come back inside.

The others all went outside, but Gen stayed by the doorframe. “Any advice? All I could say is that you should just tell her what you feel at some point, better not be too late about it.” After that, he's gone as well.

The room felt emptier, only the hums of the conditioner and the cold light of the lab enveloped him. He checks the wall clock, each second ticked continuously, making him realize he really should've thought this through better.

…

20 minutes passed, and he heard a knock from the door, making him jump a little from the random noise.

He turns the handle and opens it, when he did, he couldn't help but feel his face grow pretty hot.

You weren't wearing anything suggestive, it's just not usual for you to wear short skirts and that baggy sweater combo — which he knows he loves so much — out in the open like this.

“Ishigami?” Your voice snapped him out of his thoughts. He didn't realize he was staring.

“Sorry, come in.” He cleared his throat and led you inside. He's already fumbling it.

The lab was surprisingly clean for a guy like Senku, the research papers were organized, the floor was polished, and the whiteboard had been wiped from its formulas. It was obvious he took the time to tidy up.

“So, what do you need help for?” You questioned and gave him your sweet smile. How he missed seeing it.

Thankfully, he also prepared a problem so you actually have a reason to stay. He moved to the desk and sat on a nearby stool, pointing out sheets of paper with an equation written on it. “My brain has been lagging, so I called you in to double check these trajectory calculations for me. Xeno needs them as accurately as possible, but I'm not cut out for that right now.” His voice tried to keep that rapid and logical tone. Tried.

You couldn't help but show some concern for him, despite being exes, you still have some care for him in a way. “Have you been taking any breaks?”

“A little.” It's a lie, he hadn't taken a break for so long.

You nodded suspiciously and walked over to pull out a stool yourself to get his favor done with, not noticing how Senku's mind scrambled from the way he took a glimpse of your skirt riding slightly higher when you sat down.

Your hands took in the paper and you kept your focus on each number and variable, while he's experiencing an internal panic and using all of his effort to prevent any signs of it show.

‘This is ridiculous. I hate this. Why can't I just be with her again already? I can't believe I resorted to putting up some tricks on her.’ He mentally slapped himself for agreeing on Gen's plan. He's a coward after all.

“There it is,” You pointed out the error proudly. “I'll rewrite it myself, good thing I'm familiar with these things.” Your fingers brushed past his as you went to grab the pen across him. He jolted when he felt your warm skin for a split second.

Without wasting more time, you quickly rewrote the formula and missed no errors. “That's settled then! I'll see you next time then Ishigami.”

You moved the stool aside as you stood up and brushed yourself off. Meanwhile, the scientist blinked, baffled that there was only one measly error. He was sure he made a lot, alas he's too smart for his own good. In most aspects.

He got up and grasped on your wrist before you could fully step away from the desk. “Wait!”

“Eh?” You perked up an eyebrow, feeling flustered from his sudden contact.

To your shock, he fell onto his knees and moved his hand to grasp on you instead. Hugging your abdomen as if his life depends on it. “Please, stay.” He's… begging. The so-called logical scientist that saved humanity, is begging on the floor.

“I don't understand. Friends don't-”

“I can't handle it anymore. I don't want to be friends. I want to be with you again,” He whimpered as he cut you off and looked up at you teary-eyed. This is the first time you've seen so much emotion in him. “I realized I couldn't manage my ass without your affection. Everything you did for me was something I needed.”

“I was a dumbass for letting you go. An asshole for not changing. But now, I'll do it. Just please. I'm sure of it.” He mumbled and held you tightly against his face.

“How sure?” You questioned and moved your hand to pat his head gently.

“Ten billion percent sure.”

You swallowed a lump in your throat. Are you dreaming? It's starting to feel like one.

He braced one knee and straightened up before you, dragging his hands up your body and your face to cup it on his palms. “Does this mean I'm forgiven?”

You hovered your hands over his and chuckled softly from his question. “Yes, you are.”

“Good.” He couldn't help but let his instincts win by letting himself pull your head towards him and make contact with your lips. He groaned breathlessly on your mouth when he finally felt you again, he really did miss it.

It caught you off guard for a moment, but you melted and reciprocated the kiss, putting more pressure onto his lips.

The kiss grew from passionate to something very heated quickly once he moved you onto the edge of the desk, almost knocking out some objects sitting on it.

His body presses onto yours, making your pelvises touch and feel his erection growing. You stifled a moan and pulled away slightly, a string of saliva connected to your mouths.

“Senku, don't you think this is inappropriate, or maybe a little too fast?” Your ragged gasp when you called out his name was something he never thought to hear.

“Nah, I think it's the perfect pace.” It's obvious, he's getting needy and horny. His hands moved to your thighs, but you quickly stopped him from inching any closer.

“Just because you're forgiven doesn't mean you'll be the one in control.” You managed to compose yourself and switch your tone into something much more seductive and dangerous.

“What? You're serious.” He sighed.

“It comes with a price, I'm taking the shots now.”

Before he knew it, you swapped places with him somehow. Soon after, you dragged your fingers across the zipper of his pants and the bulge of his cock.

He groaned and unconsciously twitched his hips against your fingers, to which you pulled back immediately. “Patience, you don't get the reward if you're not waiting.”

“Fuck. Why are you doing this?” He tilted his head to your shoulder and whined helplessly.

“You made me wait for so long,” You pouted and brought your hand back to his clothed member. “Let me do this at my own pace.”

He reluctantly nodded and let you touch him so slow and agonizing. Your finger found the hook and began to open his pants, freeing his throbbing cock and his boxers which leaked with precum.

“Amazing how you give in so easily. Even more so that you're this needy. Were you that pent up without me?” You cooed and pulled down his boxers to touch him, sliding your hand and gripping on the base lightly.

“Shut up. I'm a mess when it comes to you.” He gave you a weary smirk.

After what felt like hours, you began to stroke long and unhurriedly — using his precum as lube, it's not the best option but there's nothing useful in the lab — which made him groan weakly and whimper against your skin.

Your hand gently moved along rhythmically, giving him the pleasure but at the same time the torture he deserves. You can tell he badly wants you to pick up the pace by the way he trembles from every stroke and how heavy his breathing has gotten.

“Shit, you're gonna be the death of me.” He moaned shamelessly when you started to rub his glans occasionally with your thumb.

“Have I reduced the great Ishigami to an average horny guy?” Your teasing only made his cock twitch in response. “Oh, you like that?”

Senku huffed and groaned more instead, he couldn't bother to give you any sort of remark anymore. He's intoxicated. Completely removed all rational thought left in his brain.

You allowed yourself to quicken your pace since you can tell he's getting close. Your change of speed caught his breath and made him moan louder than before. For a second you were afraid someone heard the sinful actions of yours to the scientist.

You kept your pace consistent and squeezed his shaft and head often as you went. He grasped your hips and rutted his pelvis to meet with your hand. He's definitely close now from the way he's acting like a rabbit in heat. With your free hand, you grabbed a fistful of his hair and yanked it. That was enough to make him come in your slick palm.

His semen spurted out recklessly, gutting out all of his load onto you. The moment he stops, he's left gasping for air with his tears falling down his face from hypersensitivity. His member was half-hard and tired. But you kept stroking him to help him through the aftermath, his cum all over his cock. His whiny whimpers were a blessing to your ears.

“I guess you ended up crying the most between us.”

“I couldn't help myself, you're exhilarating.” He managed to breathe out before collapsing himself onto you.

You didn't expect to get back with your ex and do a hand job on him, yet you were glad he had the guts to talk to you again. He's yours again.

Now I can finally focus on chapter 10 🤧🤧 sorry if the smut is too short I'm not that experienced huhu. If this gets some attention I might consider making more. 👀

So far I'm like 200+ words in the next chapter and I'm stumped. Not on ideas but more on how to write it, I haven't been writing much lately, not a single one-shot or drabble for so long.

Because of that, I'm planning to write an idea I have, which meant a delay on chap 10 🥹

I need more practice guys hshshs, plus I might try writing smut 👀

It's pretty much about getting back with your ex — which is Senku — with spicy scenes yk...

Tags: Fluff, short, first kiss, getting together, Senku a dork.

Timeline: Beginning of New America City Arc.

Miscellaneous: Like the title suggests, this is a drabble, not a full blown fic, but it’s more than a few bullet points. Also, @jujusrightbehindyouisntshe , thought I’d tag you since you’ve been on a Senku high lately lol.

Also, YAY GUYS!!! I appeared on the Dr Stone fan census 2026! Two years in a row I was mentioned for AO3 ✌︎('ω')✌︎ So, thank you for your continued support for my fics!

He asked you out first.

It’s not because Senku suddenly became the type of person to prioritize romance over science, nor because he spent months hopelessly pining. That would be inefficient. The man who places the survival of humanity above nearly everything else would not waste time agonizing over feelings he already understood.

Once Senku realized he cared about you, there was only one logical conclusion: address it.

So, when he finally deemed the situation relatively safe—during the sea voyage to America, beneath the quiet glow of a full moon—he told you.

There was no grand, elaborate confession. No dramatic speech about destiny or soulmates. Just Senku, blunt as always, stating the obvious.

He liked you. He wanted to be with you. Simple as that.

And afterward?

Surprisingly, not much changed.

At least, not in the ways you expected.

Senku didn’t suddenly excuse you from your responsibilities or start treating you like royalty. He didn’t become overly affectionate or abandon his scientific priorities. You were still expected to pull your weight, and he was still Senku.

But there were small differences.

He started noticing things he previously would have overlooked.

If you seemed more exhausted than usual, he would find reasons to linger nearby until you eventually admitted what was wrong. He didn’t force you to talk, and he didn’t immediately launch into a ten-step solution like you expected him to.

Instead, he listened.

Senku understood that not every problem was an equation waiting to be solved. Sometimes people needed time to sort through their own thoughts, and sometimes the best thing he could do was simply be there. So, for someone who prided himself on having an answer for everything, learning when not to give one was its own kind of growth.

Your first kiss didn’t happen during some romantic moonlit moment, either.

Actually, it happened over a “cocktail.”

Well, that’s technically a lie, it was nonalcoholic.

You were sitting with Senku at a bar, chatting away while he drank coffee because, of course, he was still Senku. The two of you were talking about something completely unrelated when he casually commented on how striking you looked beneath the warm bar lights.

It was surprisingly cheesy.

Almost painfully so.

Coming from anyone else, you probably would have teased them mercilessly.

But from Senku?

You couldn’t help but laugh.

He looked mildly offended that his observation had become the funny part, but he quickly recovered, glancing toward your drink.

“What does it taste like?”

You raised an eyebrow. “Find out yourself,” you extended your drink toward him.

Naturally, Senku leaned closer, expecting to actually taste it. Instead, you pulled the glass away at the last second and stole a quick kiss from him.

For once, Senku Ishigami was completely caught off guard.

His eyes widened slightly, his usual confidence momentarily interrupted by the fact that you had managed to outmaneuver him.

Then, slowly, he smiled, “That’s a horribly inefficient way to taste beverages.”

“I know,” you laughed.

Senku looked away for a moment, his fingers brushing against yours before he finally took your hand.

“When we get to America…” he started, his voice quieter than usual, “I hope you keep laughing like that.”

You blinked. “That’s a weird thing to say.”

“Yeah, well.” A small smile tugged at his face. “Things are gonna get rough. Maybe. Obviously. Giant ocean, unknown threats, Why-man hunt, rebuilding civilization from scratch—pretty standard protocol.”

His thumb brushed against your hand, “So having someone around who can still find something to laugh about? Pretty useful.”

You smiled. “Useful?”

“Yeah.” He glanced at you. “Don’t make me say it in a less scientific way.”

His fingers tightened around yours.

Chapter 4 - Movie Night

It's been a while since you've been talking to Senku; since it's finals this week, you two didn’t have time to talk. Your students have been nosy about your life but you just laugh it off. Some time went by and now it's your break time so you decided to visit Senku. When you arrived, you noticed his door was open but you decided to knock just in case. You heard his voice and you walked in.

“Hey,” you waved.

He looked up from his computer and smiled, “Hey,”

“What have you been up to?” you asked.

“Hm, nothing much, just grading. What about you?” he asked.

“The same as you,” you replied.

“Hey, do you want to hang out by chance? I got tickets to this horror movie I was planning on going with a friend but something came up,” he mentioned.

“Hell yeah! What time will the movie start?” you ask.

“At 5 and it's this weekend,” he stated.

“Noted,” you smiled.

“How has your day been so far?” he asks.

“Slow,” you replied.

“Hm, it’s the opposite for me,” he chuckled.

“Of course it is,” you chuckled.

You two chat about the past weeks and other things that's going until the bell rang soon after some students started to enter the classroom.

“I talked to you later then,” you waved then smiled.

“You too,” he waved back.

You walk out of his classroom and head back to yours after that the day has ended and you went home. It is now Saturday and you are getting ready to hangout with Senku at the movie theater. You put something warm on since the movie theater will be kind of cold. Your phone buzzed so you picked it and saw the text message, and it was Senku, you texted him back while grabbing your bag and quickly went downstairs to get in his car.

“Hey!” you smiled.

“Hey,” he smiles back and starts the car back up and drives to the movie theater. When you two got there, Senku handed the two tickets to the employee and went to the snack booth to order a large popcorn and two slushies. Then y'all walked into the theater room that was assigned and seated. The movie begins and you reach out for a handful of popcorn as did Senku, both of y'all hands accidently touch each other.

“S-Sorry!” you move your hand quickly.

“Haha, it's fine, go ahead,” he lightly chuckles.

You took a handful of popcorn and ate it, so did Senku. The movie continues and the movie starts to get a little scarier than a jump scare appears, you grip on Senku's jacket and he looks at you with a soft smile.

He chuckles, “Scary cat~”

“Hush!” you yelled quietly.

You both smiled at the little moment you two were having and went back to continue the movie. Soon the movie ended and both of you got up and left the movies, while you two were walking, Senku explained his opinion about the movie and so did you.

“You want something to eat before I take you home?” he asked, unlocking his car.

“That would be nice!” you said, getting inside the car.

“Alright, I know this small diner that opens 24 hours,” he replies while starting the car and leaving the parking lot and driving to the diner.

You two arrived at the diner and got out of the car to walk to the inside of the diner and sit down at the booth. Soon the waiter came and took your guy's order then left. You two waited for the food to come.

“This is a cute little diner,” you commented.

“Yea, I usually go here to do some late work or just can't sleep,” he stated.

“Night owl,” you chuckle.

“Hm, maybe I am,” he chuckled.

Soon the food arrives and you two dig inin after you two were finished he took you home. You were about to get out of the car until Senku told you something.

“Hey, Y/N, do you um, wanna go on a date with me by chance?” he asks.

You softly smile and replied, “I would like that,”

“Cool, how about tomorrow if you free,” he stated.

“Sure, that can work,” you smiled.

“Alright, see you tomorrow,” he waved.

“You too,” you wave back and get out of the car and walk to your apartment.
