Characters: Shin Asakura, Yoichi Nagumo, Seba Brothers, Gaku, Heisuke Mashimo

A/N: Hope you like this one OwO

---

~~Shin Asakura~~

When you pull away from him with that wide-eyed fear, it hits him like a ton of bricks. He hears it in your thoughts before you even speak it. “He's dangerous... what if he snaps?"

Shin freezes. His heart pounds, not because you’re wrong—he has killed people—but because you’re terrified of him, not what he’s done. That distinction shatters something inside.

“You think I’d ever hurt you?” he asks softly, voice cracking a little as he gently lowers his hand, like even touching you would confirm your fears.

He gives you space. Too much space. For days, he barely meets your gaze, too afraid of what he’ll hear in your mind again.

Eventually, he breaks, sitting outside your room like some kicked puppy. “I’ve done terrible things,” he admits. “But if I could hear just one thought from you where you trusted me again… I’d do anything for that.”

When you finally reach out, saying, “I just needed time to process,” he leans into your touch like a dying man given water. He whispers, “Then take all the time you need. I’m not going anywhere.”

He’ll never stop being protective—but he’s more careful now, more open. And when you finally kiss him, hands trembling, he doesn’t read your mind. He wants to feel your trust the human way.

---

~~Yoichi Nagumo~~

He laughs it off at first. “You scared of me? Babe, I’m the guy who brings you takeout and clips your cat’s nails.”

But when you flinch at the sound of his knife clicking open, everything stops. His expression drops like a mask falling away.

“You know, I pretend a lot,” he says, almost too casually. “Happy-go-lucky, pretty-boy hitman. But pretending you’re not afraid of me? That one really hurt.”

He disappears for a day or two. Not because he’s angry, but because he needs to figure out if being in your life is actually hurting you more than helping.

When he comes back, it’s late. Rain clings to him. He crawls into your bed fully clothed, laying next to you with his back to yours. “I never wanted you to see that part of me,” he murmurs. “But if you’d rather see the truth than love a lie, I’ll show you everything.”

He opens up like never before. About his past, about how much of it he regrets, about how every time he holds a blade. He thinks of what he could lose.

And when you finally touch his face and say, “I trust you,” his smirk returns, slower this time. “Then I’ll treasure that trust because you have no idea how much it matters to me."

---

~~Natsuki Seba~~

He gets quiet—scary quiet—when you recoil from his smile after hearing a story about one of his past missions.

“So it’s finally come to this, huh?” he says, pulling off his glasses and cleaning them slowly. “The moment when you realize I’m a monster.”

But there’s no bite in his voice—just exhaustion. He’s used to being seen as a weapon, a tool, a successful test subject. But he thought you saw him as human.

He doesn’t beg. Doesn’t plead. Just... slowly starts building walls. Talking to you only when necessary, pulling all-nighters again, isolating himself in data and chemicals.

When you confront him, saying, “I was scared, not disgusted,” he doesn’t believe you. Not at first. “You wouldn’t be the first to lie to me,” he mutters.

You finally break through when you patch up a wound he didn’t even ask you to touch. “You’re still you,” you whisper. And he grabs your wrist—hard—not to stop you, but because he’s shaking.

That night, he kisses you like a dying man. Desperate, soft, and scared. “If I scare you again,” he says, forehead pressed to yours, “tell me. I’d rather break myself apart than lose you.”

---

~~Mafuyu Seba~~

It’s a knife to the chest when you say, “I don’t know who you are anymore.” And Mafuyu just… smiles. Like he was expecting this.

“You were the one good thing I didn’t have to earn,” he says coldly. “Guess I got that wrong too.”

He shuts down completely. Barely sleep. Doesn’t text. You find his coat on your couch like he meant to come home but couldn’t.

The worst part? He wants to fix it. But he doesn’t know how. He was raised on logic and rules—emotions are messy, unpredictable. Dangerous. For the longest time, he never even had the guts for skin-to-skin contact. You were the first person to jump over the high walls.

So you break the silence first. You find him slumped over a desk, staring at a photo of you two. “Were you ever going to come back?”

“I was scared I’d break something that mattered,” he admits, looking up with raw eyes. “I don’t know how to be loved and feared at the same time.”

You hold him close and say, “Then let’s figure it out together.” His kiss is shaky, tender, and terrified. “I’ll make myself better,” he promises.

---

~~Gaku~~

He’s not surprised when you back away. He saw the fear in your eyes the moment he told you the truth.

“You thought I was just some weird, messy guy with a sharp tongue,” he mutters. “Turns out I’m also a trained killer. Surprise.”

He doesn’t beg or apologize. He just leaves. Ghosts you. The type of silence that tastes like blood and old memories.

You find him again by accident, nursing a busted lip in an alley. “Why didn’t you say goodbye?” you ask.

“Because I knew you’d try to stop me,” he replies, not meeting your eyes. “And I couldn’t watch you look at me like that again.”

You walk up and cup his jaw, thumb brushing his bruise. “You scare me,” you admit. “But I still love you.” That’s when he breaks, he hides his face in your shoulder and just breathes, like it’s the first real breath he’s taken in days.

Later that night, his touch is rough but reverent. He kisses your scars and his own. “If you ever want out,” he says, “I’ll let you go. But until then—I’m yours, even if I don’t deserve it.”

---

~~Heisuke Mashimo~~

He tries to joke it off. “I mean, who hasn’t accidentally blown something up, right?” But when you don’t laugh, he realizes this is serious.

His heart drops. “You think I’d hurt you?” he says, so softly it breaks your heart. “I’ve never even raised my voice at you.”

He spirals hard. Convinces himself you’re better off without him, that he’s too reckless, too unstable. He starts sleeping in his van again.

The guilt eats at him. You hear him muttering in his sleep—begging for forgiveness, apologizing to you, to the people he's failed.

You sat down next to him one night and said, “If I didn’t care, I wouldn’t be here.” He just stares at you like you’re some miracle he doesn’t deserve.

He hugs you too tightly. Buries his face in your neck like you’re his only anchor. “Please don’t be scared of me,” he whispers. “I’d rather blow myself up than hurt you.”

That night, he’s surprisingly tender. Fumbling, awkward, but passionate. “I’m yours,” he says between kisses. “Just tell me what to fix and I’ll do it.”

— CRUSHING x sakadays

summary . what does it look like when the both of you are crushing on each other?

wc . 1.6k

cw . nothing much to be worried about !! not edited, so sorry for any mistakes / things thst don’t add up

the characters areee : shin asakura , kei uzuki , nagumo yoichi , heisuke mashimo , natsuki seba , gaku , shishiba

masterlist ౨ৎ

shin asakura

oblivious scale : 7 . shin’s obviously got some insider info on what you’re feeling, but he’s surprisingly oblivious. i feel like he’d feel suupppeer guilty for reading your mind— that and he always gets distracted whenever he has a chance to hear any important thoughts that could give him an idea of how you feel about him. next time, for sure, shin thinks— and the next time he’s already fighting back the urge to bash his head against the wall in both nervousness and embarrassment, then the opportunity slips away.

hc : constant hand-brushing . shin reeaallly doesn’t mean for it to happen, and he knows that you don’t either— because he can literally hear the way your thoughts stutter and stop for a moment as his fingers lightly brush against yours. he thinks it’s just soooo cute !

hc : all of your favorite things find themselves in your hands . he knows exactly what you want and what you like. ‘oh man, that keychain is so cute.’ you think to yourself— and in the following days, shin is suddenly holding out that exact same keychain for you with flushed cheeks.

kei uzuki

oblivious scale : 4 . he most definitely knows that you have some type of feelings for him— kei can understand that much. but either way, he still feels just a little unsure about this all. like, how does he know his mind isn’t playing tricks on him? but he thinks that look on your face is pretty sincere.

hc : constant eye contact . uzuki doesn’t even mean for it to happen. his gaze just naturally meets with yours! sure, he sometimes glances over to your on purpose, but other times it sort of just.. happens.

hc : lingering . the man really likes being close to you, he realises. so it’s only natural that he’s just a little hesitant to leave your side. “bye, uzuki.” “bye, (name).” and the two of you just stand there in silence. and once you finally do walk away from him, albeit a little hesitantly, he stays standing for a few seconds. uzuki stares, dazed, before he finally leaves too.

nagumo yoichi

oblivious scale : 1 . nagumo deeeeffiiinittleyyy knows. he probably knew even before you did! he only feels a little doubt sometimes, but they quickly wash away when he catches a subtle glance from you.

hc : spontaneous visits . he can’t help it! he just wants to be with you allll the tiimmeee. so, don’t be surprised when you hear knocking on your door and nagumo standing there, covered in blood and smiling widely.

hc : casual touching . now, nagumo’s not overbearing at all with his touching at all. sure, he likes to pat your head or your shoulder, maybe hold your hand or poke at your cheek— but he never touches you enough to cross the lines of.. whatever you’ve got going on. he thinks it will stay this way for a while. holding hands but never intertwining fingers. patting your head but never stroking your hair. poking your cheek but never caressing it.

heisuke mashimo

oblivious scale : 9 . this one shouldn’t be too surprising. i mean, this is heisuke we’re talking about. however, he’s surprisingly perceptive at time— but he just doubts himself. you smiled at him? that definitely means you like him, right?! wait, no.. you’d never like a guy like him..

hc : doodling . heisuke isn’t sure how he’s supposed to make a move. the man spends a few days thinking, his thoughts rolling around his head like little marbles as he bashes his forehead against a wall. he doesn’t know what to do!— until he gets it. he finally thought of something. he’ll draw you a portrait! however, when the picture finally finds it’s way to your grasp, you’re not sure if this is supposed to be a threat or a compliment. it’s the thought that counts, so you give heisuke a beaming smile— a smile that makes him want to draw one million more pictures for you if he gets to see that smile again. so, every now and then, heisuke shyly hands you a little paper— or piisuke brings it to you!

extra : doodling . additionally, he likes to draw on your hands. his warm hand grabs yours, the other shakily holding onto a pen. you agreed to let him do this, so it’s okay, he reminds himself. the end product is a little wobbly, but cute!

hc : acts of service . heisuke doesn’t have the funds to buy you expensive and lavish items, so he’s decided to compensate for that by becoming your personal dog. okay, not actually. but he overhears you saying you’re tired? do not worry, heisuke is already on his way to give you a piggy-back-ride! need water? he’s scrambling to share his water bottle with you!

natsuki seba

oblivious scale : 3 . natsuki is pretty sure that he’s got a pretty firm grasp on what you feel of him, judging by the way you linger in his workshop, occasionally asking about him or bring him something. but what if you’re just being friendly? he sighs, figuring that dwelling on it will do no good.

hc : sweet sharing . one thing that the two of you have made a tradition is for you to bring him something sweets sometimes when he’s busy in the workshop. at first, he was a little confused— why is this random person coming here with sweets for him? are they poisoned? but once he realises you’re a friend of shin’s, he guesses you’re probably not the type to do that. so he had some of those for the rest of the day— and just like that, you started to come by more often. he wonders where you get all these sweets from. one day, though, he decides to do something. “(name),” he calls out for you as you move to leave. you glance back at him curiously. “yes?” “stay. let’s share.” natsuki offers, gaze shifting away from the weapon he’s working on and meeting with yours. ever since then, you both share these sweets together.

hc : metal flowers . natsuki is obviously good with metal and stuff like that— so it’s obvious he’d use his skills to impress the person he likes. he works for a few nights, perfectly crafting some roses from metal. he didn’t really feel like buying an actual bouquet— because those wither rather fast— so, he settled with these. he binds a small strip of metal into a bow around the stems of these flowers, and a small, proud smile graces his lips.

gaku

oblivious scale : 0 . gaku absolutely 100% knows about how you feel. he can tell by that little sparkle in your eyes whenever he’s around.

hc : casual closeness . you’re just casually sitting on a couch in the hideout, humming absentmindedly to yourself as you scroll through your phone. that game looks cool, you think. d just as you write down a reminder to buy that game, you feel a figure slide onto the couch beside you. his (very nice and delicious) muscular arm resting on the back of the couch, his forearm just barely brushing against the back of your head. you swear that you feel a chill down your spine. you snap your head to look at the offender— a man named gaku. he just stares blankly, before his lips curve into a lazy smirk. heh. he knew you’d react like that. the man’s definitely not shy to get close. standing behind you, his breath gently fanning over the back of your neck? daily occurrence at this point. linking his arm with yours when he feels like it? easy. resting his chin on your shoulder? why are you so fidgety? oh, why are you getting so flustered when his hand reaches for yours?

hc : annoying touches . gaku thinks you’re really funny when you’re startled. he first realised this when his hand accidentally latched onto the hood of your jacket and tugged you down a little. you yelped, turning around and blinking back at gaku. that’s how he fell in love with these reactions. ever since then, he’s found great pleasure in tugging your hair lightly, pulling you back by the hood of your jacket, pulling your shoes off when you’re sitting down, and other things that he’s noticed you react to. he just gives you a nonchalant shrug when you confront him about it— but the subtle flush on the tips of his ears, and the almost unnoticeable curve of a smile on his lips betrays his enjoyment.

shishiba

oblivious scale : 0 . shishiba knows. he knew since the start.

hc : walking home . the first time you two walked home, it was a rainy night. raindrops were pouring, and the skies were dark and cloudy. you’re way too close to home, so you’d feel bad catching a bus or or taxi. shishiba gives you a side-glance, taking note of your contemplative expression. “i have an umbrella.” he says, his gaze shifting away from yours. “let me walk you home.” shishiba adds, clearing his throat softly. and with that, you both started to walk home together more often. or to the nearest train station, bus stop, etc.

hc : hair ties and hair clips . shishiba once overheard you complaining about your hair bothering you. and he’s definitely noticed it— the way some strands brush against your face in the wind, and the quiet huff that escapes your lips as you attempt to soothe your hair. so, one day, he offers you a hair clip. it’s now become a habit for him to give your hair ties or clips if he notices you becoming particularly agitated by your hair.

Heisuke whines a lot when he's inside you

Very very canon...I feel like there are a few guys like this - heisuke, shin, choso, august, takuma...

You’re straddling his lap, soft moans escaping your lips as you grind slowly over his bulging sweats. He throws his head back, his hand gripping tightly on your thighs, his mouth in a gentle ‘o’. 

You don’t bother removing your underwear, you’ve been like this for some time now, leaning over your boyfriend’s chest, attached at the mouth. You pull the soaked fabric aside and free his now throbbing cock from his sweats. Running your thumb slowly over the thick vein on the underside, his adam’s apple bobs as he swallows dryly and a soft whimper escapes his lips. 

‘Oh…does that feel good?’ you ask feigning ignorance.

He nods feverishly, his head still laid back and his cock twitching in your hands. You line him up gently and lean further forward, his chest heaving underneath you in anticipation. His hard cock slips in easily and you sink down slowly, your walls clenching around him - shocked by the sudden fullness. Head whipping up, you feel his hot breath by the shell of your ear as a broken whine emerges from his lips. You shudder at the sound, your hole involuntarily squeezing around him. 

‘Oh shit…you feel so…good’ he whimpers, broken and high pitched. 

His whines and moans go straight to your pussy as you feel your wetness leaking around his cock. You loved these sounds he makes as you clench around him. You arched your back, grinding painfully slowly, pressing down hard to take him as far as possible. 

‘Oh…ngh’ He whimpers and gasps incessantly in your ear, chills running down your neck.

‘Wait…stop-p…I can’t come…ye..t’ his voice breaks, small and pathetic. Smiling against his cheek wickedly you lift yourself right to his leaking tip and slam down in one swift motion. His hands rush to grip your waist as he buries his face in the crook of your neck, desperately trying to subdue his helpless whines. 

You hold his chin as you tip back his tear stained face.

‘Oh no…head back baby, I wanna hear you cry’
