Summary: Spending your birthday with Satoru is never quiet, never simple, and never boring. From the moment he barges in at dawn to the last laugh before sleep, he’s determined to make it unforgettable in only the way he can.

------------------
It was far too early for anyone to be awake on their birthday. The sun had only just crept over the rooftops, painting the curtains with a pale gold glow, when your door slammed open so hard you nearly thought an intruder had broken in.
Instead, it was Satoru.
“Happy birthday to the most important person in the world—besides me, of course!” he announced at top volume, dragging out the last words with a laugh.
You blinked blearily against the confetti raining down on you. Actual confetti. He had somehow timed it so that the moment the door opened, a cloud of it shot straight into your room.
In his other hand, he carried a bunch of balloons shaped like ridiculous cartoon animals, bobbing and squeaking against each other as he moved. Balanced precariously under his arm was a cake box—your name scrawled across the top in bright blue frosting letters you could already imagine were his doing, not the bakery’s.
“Satoru—” Your voice cracked, still rough with sleep. “It’s seven in the morning.”
“Exactly,” he said, grinning. “Prime birthday hour. You think the sun got up this early just for fun? No, sweetheart. It’s celebrating you. I had to beat it to the party.”
Before you could argue, he shoved a glittery paper hat onto your head. It had a giant pom-pom at the top and “Birthday Royalty” stamped across it in sparkly letters. You groaned, but he clasped his hands dramatically, tilting his head.
“Perfect. Absolutely stunning. Vogue could never.”
You sat up slowly, brushing confetti from your hair, and eyed the cake box. “Are you seriously making me eat cake before breakfast?”
“Oh, don’t worry about breakfast,” he said, turning on his heel like a man on a mission. “I’ve got that handled.”
That should’ve been your first warning.
Five minutes later, smoke curled from the kitchen.
“Satoru!” you shouted, scrambling out of bed. The sight that greeted you was both horrifying and exactly what you’d expected: flour dusting the counters, egg shells scattered like shrapnel, a pan smoking violently on the stove. Satoru stood in the middle of it all, spatula in one hand, apron hanging askew, looking ridiculously unbothered.
“Relax, babe,” he said, waving the spatula around like a conductor’s baton. “This is totally under control.”
“You set the stove on fire.”
“Minor setback.”
“You cracked eggs directly into the toaster.”
“Experimental cuisine. Don’t limit my genius.”
You pressed a hand to your face, sighing, while he leaned casually against the counter, all six-foot-three of smug confidence in an apron that read Kiss the Cook.
“You know what,” he said, snapping his fingers like he’d just remembered something, “I actually had this planned all along. No one wants lumpy pancakes when you could have gourmet takeout ones.” He pulled his phone from his pocket, already dialing. “See? Totally intentional. Gojo Satoru does not fail, he improvises.”
You couldn’t help laughing, even as you opened the windows to air out the smoke. He caught the sound immediately, his smile softening beneath the theatrics.
“That’s the real birthday gift,” he said, voice dropping just enough to cut through his usual playful pitch. “Making you laugh before coffee. I’m unstoppable.”
By the time you sat down with a proper breakfast—fluffy pancakes stacked high, delivered by a very confused courier—Satoru had already cut a slice of the birthday cake “for quality testing.” You rolled your eyes, but he leaned across the table to crown you again with the ridiculous birthday hat, grin wide and boyish.
“Happy birthday, sweetheart,” he said, quieter this time, sincerity peeking through the chaos.
And despite the mess, the smoke, and the confetti still clinging to your pajamas, you couldn’t imagine a better start to the day.
------------------
By late morning, you’d just finished cleaning stray confetti out of your hair when Satoru suddenly appeared in front of you, grinning like he’d been plotting this moment for hours. Which, knowing him, he had.
“Mission time,” he declared, holding up a black silk blindfold. “For authenticity.”
You frowned. “Authenticity for what?”
He ignored the question, stepping closer to tie the fabric over your eyes. His fingers brushed your temples with surprising care, knotting it gently at the back of your head. His voice dropped to a conspiratorial whisper. “Don’t peek. Top-secret birthday mission.”
“Satoru—”
“Nope. No spoilers.” He clapped his hands and suddenly, the world around you shifted.
It wasn’t just walking. One moment you were in your apartment; the next, the air smelled different, alive with sugar and popcorn. You felt the faint rush of wind against your skin, his Infinity buzzing faintly as if he’d bent space just for this.
When he tugged the blindfold off, you squinted against neon lights. An arcade stretched out before you—rows of glowing machines, flashing screens, and the faint hum of game music. Satoru was practically vibrating beside you, an infuriatingly cocky smile tugging at his lips.
“First stop,” he said, gesturing grandly. “The land of champions. And by champions, I mean me, because obviously I’m about to destroy you in every game.”
“Uh-huh.” You crossed your arms, already suspicious.
True to form, Satoru dove headfirst into the competition. He dragged you from one machine to the next—racing games, air hockey, rhythm games—and somehow managed to both play seriously and narrate everything dramatically, as though you were contestants in some televised tournament.
When you actually managed to beat him at skee-ball, he gasped like you’d committed treason. “You dare dethrone me on your birthday? Cruel.”
“Maybe you’re just not as good as you think,” you teased.
He pressed a hand over his heart. “Blasphemy. Slander. Lies.” Then he immediately grabbed your wrist and pulled you toward the claw machines. “Watch closely. This is where I prove myself.”
You raised a brow. “You’re going to fail, aren’t you?”
“Excuse me? I am the strongest.” He flexed his fingers theatrically before sliding coins into the slot. The claw descended, missed the plush, and clanked empty against the chute.
You smirked. “Strongest, huh?”
His blindfold twitched as if he’d narrowed his eyes. “That was a warm-up.”
On the second try, you caught the subtle shimmer of Infinity guiding the claw. Sure enough, it snagged a stuffed animal—a ridiculous pink bunny—and dropped it neatly into the prize bin. Satoru whipped it out like a magician pulling a rabbit from a hat and presented it to you with a flourish.
“See? Your boyfriend’s not only the strongest sorcerer, but also the strongest at claw machines. Legendary multitasker.”
You took the plush, laughing. “You cheated.”
“I enhanced my natural talent,” he corrected, snapping a selfie of the two of you with the bunny squished between your faces.
That set the tone for the rest of the afternoon. Every game turned into a photo op. Satoru insisted on documenting everything: you laughing mid-throw at the basketball hoop, you rolling your eyes while he posed dramatically with plastic tickets draped over his shoulders, you holding a churro while he leaned in with mock jealousy. He must’ve taken a hundred selfies, half of them blurry because he couldn’t stop laughing at his own antics.
Eventually, when you were both carrying far too many cheap prizes and your cheeks hurt from smiling, he whisked you away again—another sudden lurch in the air, another shift in atmosphere. This time, it reveals something quieter: a rooftop garden overlooking the city. The late afternoon sun stretched golden across the skyline, casting long shadows.
Satoru sprawled across a bench, patting the space beside him. “Bonus round,” he said, tilting his head toward the view. “Thought you might want something a little less flashy, too.”
You sat, the cool breeze brushing your skin, and glanced at him. For once, he wasn’t performing. His lips curved into a rare, real smile that always made you blush.
“Happy birthday,” he murmured, softer than before. “Still more surprises to come, but…this one’s just for us.”
And with that, he leaned in, snapping another selfie—but this time, it wasn’t loud or exaggerated. Just the two of you, framed by sunlight and skyline, a quiet pause in his whirlwind of chaos.
------------------
By the time you got back from the rooftop, your arms full of arcade prizes and a sugar high from all the snacks, Satoru was still buzzing with energy. You, however, were starting to feel pleasantly heavy—too much laughter, too much sugar, too much chaos packed into a few short hours.
He noticed. Of course he did.
“Birthday nap time,” he announced the moment you kicked off your shoes. He flopped onto your couch like he’d lived there his whole life, stretching out dramatically until he occupied every cushion. “Doctor’s orders. And by doctor, I mean me, because I clearly have the qualifications.”
You raised a brow, amused. “You’re the worst doctor ever. Don’t even think about hogging the whole couch.”
“Relax, I’m the best pillow you’ll ever have.” He patted his chest invitingly.
Against your better judgment, you gave in. The sun filtered through the window in soft beams, the room warm and quiet after the morning’s madness. You curled up beside him, head pillowed against his shoulder. He immediately draped an arm over you like it was the most natural thing in the world.
For a few minutes, neither of you spoke. Just the steady hum of the city outside, the rhythm of his breathing, and the faint brush of his thumb tracing idle circles against your arm. He was unusually still, no quips or ridiculous commentary. Just present.
Then, softly, almost like he didn’t mean for you to hear: “Birthdays are weird, you know? They sneak up on you. Remind you how fast time runs.”
You tilted your head, surprised by the tone. Satoru rarely let seriousness slip into his voice.
Before you could respond, he chuckled, covering it with his usual bravado. “Anyway! That’s why I get clingy on days like this. Gotta make sure you don’t age without me attached to your side. Tragic if you did.”
You laughed, though your chest warmed at the confession hidden beneath the joke. He shifted, pressing his cheek briefly to the top of your head, as though the contact itself anchored him.
After the nap—short and sweet, just enough to recharge—you woke to find him rummaging in a shopping bag you didn’t remember seeing before. He turned at your groggy question, his grin back in full force.
“Oh, good, you’re awake! Just in time for part three of the birthday extravaganza.”
He started pulling things out one by one: an enormous box of gourmet chocolates, your favorite rare snack imported from overseas, and a bakery bag stuffed with pastries. You blinked as the pile grew, until the entire coffee table was covered.
“Satoru, this is—this is too much.”
“Nonsense.” He waved a hand like your protests were irrelevant. “You deserve all of it. Besides, I didn’t stop there.” He ducked back into the bag and produced something small, neatly wrapped, clearly expensive. Jewelry.
You gaped. “You can’t just—”
“I can,” he interrupted smoothly, pressing the box into your hands. “And I will. Because I’m me, and because you’re you.”
When you hesitated, he tilted his head, feigning innocence. “What? You thought I was gonna show up with only confetti and pancakes? Please. I may be dramatic, but I’m also thoughtful. Deadly combo.”
You opened the box carefully, touched by how much consideration went into the gift. He leaned closer, voice soft, teasing but sincere. “See? Totally no big deal. Just…don’t ever say I don’t spoil you.”
It was ridiculous, overwhelming, so very Satoru. But as you sat there surrounded by sweets, sunlight, and the warmth of his grin, you couldn’t deny the truth: beneath the jokes, beneath the chaos, this was his way of saying he cherished you.
------------------
By the time evening rolled around, you thought maybe the chaos had finally run its course. Satoru had already given you confetti, pancakes, plushies, naps, and more sweets than a small army could eat. Surely, you figured, he’d settle for just ordering takeout and calling it a day.
But then he disappeared into your bedroom and came back out dressed in a crisp button-up and blazer, blindfold still perfectly in place. He tugged at his cuffs with exaggerated flair, striking a pose in the doorway.
“Well?” he asked, smirk tugging at his lips. “Hot, right? Don’t all answer at once.”
You rolled your eyes, though you couldn’t deny it—he did look good. “You couldn’t take the blindfold off and use your glasses for once? Just for dinner?”
He gasped dramatically, clutching his chest. “Excuse you, this is my brand. My charm. My mystique. Besides, wouldn’t want you falling even harder for me tonight. Dangerous levels of attraction.”
Before you could retort, he offered his hand with a courtly bow. “Come on. Reservation awaits.”
You let him guide you, amused and curious. When you finally arrived, it wasn’t just a restaurant—it was a rooftop terrace, string lights glowing overhead, the city sprawling in glittering patterns below. A single table had been set up, white linen, candles, the works.
Your breath caught. “Satoru…”
“Told you,” he said smugly, pulling out your chair with a flourish. “Only the best for my favorite human.”
Dinner itself was a spectacle. He ordered enough food for three people, insisting “birthdays require feasts.” He teased you relentlessly, trying to feed you bites just to watch you squirm, snapping selfies mid-meal, whispering ridiculous commentary about the other diners even though you two were alone.
But in between the theatrics, he slipped in comments that made your heart stumble.
“You look incredible in this light, you know.”
“I’m glad I get to be here today. With you.”
“Do you have any idea how lucky I am?”
Each one delivered so casually, like he hadn’t just stripped away your defenses with a handful of words. Every time you looked at him in surprise, he grinned like nothing had happened, pouring you more water or offering another bite of dessert.
When the plates were cleared, he leaned back in his chair, producing a small wrapped box from his pocket. “Final gift,” he announced, sliding it across the table with a grin. “Been saving this one.”
You eyed it warily. “If it’s more cake, I swear—”
“Even better,” he interrupted. “Socks.”
You blinked. “…Socks?”
He nodded, straight-faced. “Very practical. Everyone loves socks. I even picked your size. You should be thanking me right now.”
Against your better judgment, you opened the box. Inside, neatly folded, was indeed a pair of novelty socks—bright, patterned, utterly ridiculous. You stared at them, speechless.
Satoru burst out laughing. “Oh my god, your face! Priceless. Don’t worry, that’s not the real present.”
He reached into his jacket pocket and pulled out another box, this one sleek and unmistakably expensive. Sliding it across the table, his grin softened. “Okay, now open this one.”
Inside lay a delicate piece of jewelry—something clearly chosen with thought, tailored perfectly to your taste. Not flashy, but personal.
You looked up, touched, and caught him watching you from across the candles, blindfold off. For once, his expression wasn’t smug or teasing, but quietly earnest.
“See?” he said softly, resting his chin in his hand. “I can be serious sometimes. Just don’t tell anyone—I’ve got a reputation to uphold.”
The warmth in his voice hit harder than any confetti storm or rooftop dinner. And as he leaned across the table to snap one last picture—your stunned face lit by candlelight, the city sparkling behind you—you realized he’d given you more than just a gift. He’d given you the kind of memory that couldn’t be wrapped, boxed, or tied with ribbon.
------------------
The night air was cool when Satoru led you away from the glowing terrace. Dinner had left you full and a little drowsy, but he insisted there was one last stop. He walked with his usual swagger, but his hand never left yours, warm and steady as he guided you up another flight of stairs to the very top of the building.
When you stepped onto the rooftop, the city spread out below like a sea of stars—but above, the real constellations burned even brighter. The sky was perfectly clear, every pinprick of light sharp against the dark canvas. He flopped down on the flat concrete without hesitation, patting the space beside him.
“Come on, birthday star. Let’s give these losers a run for their money.”
You stretched out next to him, shivering slightly until he tugged you against his side. He tilted his head back, blindfold aimed at the heavens. “See that?” he said, pointing vaguely upward. “That one’s jealous. You’re clearly brighter.”
You laughed softly. “Satoru, you can’t even see the stars through your blindfold.”
“Details, details.” He waved his hand. “The truth is universal: you’re prettier. The cosmos agrees. Probably plotting your fan club as we speak.”
You rolled your eyes, but his tone was lighter than the words suggested—like he wanted you to believe it, even if he had to wrap it in ridiculousness.
For a while, you just lay there, listening to the hum of the city far below and the steady rhythm of his breathing. The usual sharp edges of his voice softened in the quiet, his jokes trailing off into silence. Then, unexpectedly, he spoke again, quieter this time.
“You know,” he said, “days like this remind me why I don’t mind all the noise. The teaching, the missions, the curses. It all feels less heavy when I get to come back here. To you.”
You turned your head, startled by the sincerity that slipped past his walls. He wasn’t grinning now. Just resting his hands behind his head, expression unreadable beneath the blindfold, but his voice steady and unguarded.
“Life goes fast,” he continued. “Too fast. People disappear, things change. But tonight, you’re here, and I’m here, and that’s… enough for me.”
Your chest tightened at the rare vulnerability in his words. Before you could respond, though, he blew out a loud, exaggerated sigh and shifted back into performance mode. “Anyway! Enough of that mushy stuff. You’ll ruin my cool image.”
You nudged him lightly, smiling. “You never had one.”
“Rude,” he said, but his arm tightened around your shoulders.
The two of you stayed like that until the night deepened, stars wheeling silently overhead. Just when you thought he might have actually fallen asleep, Satoru began humming. Loudly. Dramatically. The tune was unmistakable: “Happy Birthday.”
You groaned. “Satoru. Stop.”
“What? You didn’t think I was gonna serenade you under the stars? This is peak romance.”
“You sound like a dying walrus.”
He gasped. “Insulting the strongest singer alive? Cruel. You wound me.”
Still, he kept going, louder and more ridiculous until you covered his mouth with your hand. “Shut up.”
His laugh vibrated against your palm, muffled and amused. He finally relented, humming a few more bars under his breath before trailing off.
Eventually, the rooftop grew quieter again, only the soft rush of wind and the faint sounds of traffic below. Satoru shifted, tugging you closer until his entire frame draped over yours, heavy but comforting. His breathing slowed, his usual endless energy finally giving out.
Just before sleep claimed him, he murmured, voice low and warm, “Happy birthday, sweetheart.”
Moments later, he was out—smug even in slumber, a faint smile tugging at his lips. And as the stars watched overhead, you realized it was the perfect ending: messy, loud, ridiculous, and yet so full of love. Entirely, unmistakably Satoru.
like. those moments where you're debating Getting Up because you can't stand staying still for much longer, but also don't want to move because it takes Effort? Suddenly Baby is laying on you and being comfy and adorable, just. smiling at you. as if he knows he's making your dilemma worse.
definitely steals your food, or at least has his chin on your shoulder just. staring at you. while you eat, waiting for something to be offered to him (if you don't take the hint he takes your hand and brings your food to his mouth instead)
silence in the house is a sign he's up to mischief /j
he & mystery probably both will & have fallen asleep on the floor in a sunbeam
i wouldn't put it past him to knock things off of tables just to get reactions tbh.
Ok, I love this.
Also, this is my cat. He does all of this, mostly when it is inconvenient for me.
Helloo, I have a weird but specific question. If it's too weird, you can just ignore this.
If the Saja boys have a cafe date with the reader, what would their food and drink order be?
Or generally what their favorite food and drink is, in your opinion.
I needed some opinions for my story, so I'm asking you, along with other authors
Thank you, have a good day/night
Hi! Not weird at all — usually I wouldn’t do this kind of ask at the moment, but I’m answering since you mentioned it’s for your story. Thanks for including me, and I hope these help!
Jinu – Herbal tea. He’ll get a seasonal pastry.
Abby – Iced latte with extra syrup. Ham and cheese croissant or egg sandwich.
Mystery – Black coffee and something plain like shortbread.
Romance – Rotates between the trendy drinks. Will split a slice of cake with you.
Baby – Most sugary frappuccino possible and a giant chocolate muffin.
Speaking of being sibling zoned… how would the Saja boys react if they got sibling zoned?
I feel like Romance would be the most dramatic one but all of them would be surprised one way or another 😂😂
- 🌊 (Harbinger of Chaos)
oh you’ve opened a can of worms with this one 🌊 let’s go:
Jinu – Blinks slowly. Quietly nods. Walks away. Spends the next 3 hours spiraling in a corner trying to figure out where he went wrong.
Abby – Literally says “aw man 😔” out loud. Recovers quickly and tries to act normal but accidentally crushes a mug later thinking about it.
Mystery – Stares at you blankly for a full ten seconds. Disappears into the nearest shadow. No one sees him for a week.
Romance – Dramatically clutches his chest like you stabbed him. Whispers “sibling?” in disbelief. Forces a smile while planning a 40-step long seduction arc to change your mind.
Baby – Goes dead quiet. Doesn't speak to you for a solid 48 hours. Eventually comes back with a “so what would it take for me to not be your brother?”
