Chapter Text
Seoul always felt like it was moving even when it stood still.
Morning traffic rolled by in long, patient lines, tires hissing over damp asphalt left behind by last night’s rain. The air had that clean, almost metallic bite that came after a storm and everything looked sharpened by it—street signs, crosswalk stripes, the glossy shine of convenience store windows. Somewhere down the block, a café door opened and warm coffee smell slipped into the street like a secret.
Taehyung stepped off the bus with the kind of unhurried ease that made punctual people want to throw things.
His tie hung loose, the top button of his shirt undone and his backpack sat on one shoulder like he couldn’t be bothered to remember the second strap existed. He walked past the school gate in a slow drift, skimming the edge of a puddle with his shoe, watching the water scatter across the pavement.
He didn’t look down to see if it hit his uniform.
That would imply regret.
Inside the school building, the hallway noise hit him in a familiar wave—lockers slamming, sneakers squeaking, voices layered over voices until it all became one steady pulse. Students clustered in little knots, comparing homework, whispering gossip, complaining about teachers. A group of first-years hurried past like they were afraid the walls would swallow them if they slowed down.
Taehyung slipped through the chaos like it was background music made specifically for him.
He didn’t mind school the way some people did. It wasn’t the classes or the rules that bothered him.
It was the assumption that he should care.
He pushed open the classroom door with a casual nudge of his shoulder.
The first thing he noticed wasn’t the teacher at the front or the half-asleep students. It was the tension—soft, quiet, stretched tight across the room like a string about to snap.
Their math teacher stood by the board holding a sheet of paper, scanning the class with a calm, prepared expression.
Taehyung recognized that look immediately.
It meant somebody had decided to make everyone miserable on purpose.
He dropped into the nearest seat at the back, leaning back so far the chair protested with a low creak. He stretched his legs under the desk as if he lived there.
A girl two rows ahead leaned toward her friend and whispered, “Oh no.”
Her friend sighed like she’d been sentenced.
Taehyung’s mouth twitched with amusement.
The teacher cleared his throat.
“We will be changing seating arrangements today.”
A collective groan rolled through the class like thunder that couldn’t quite commit to being a storm. Chairs scraped. People started bargaining immediately—soft, desperate negotiations about who owed who a favor, who needed to sit near the front for their eyesight, who would literally fail if they couldn’t sit with their friend.
Taehyung closed his eyes dramatically and tipped his head back against the wall.
Of course.
Because the universe had looked at his perfectly normal day and decided it would be fun to shake it like a snow globe.
The teacher began reading names.
One by one, students moved, complaining under their breath. The shuffling felt endless. Taehyung didn’t bother to check the list being taped to the board, didn’t bother to look interested. He watched a droplet of water slide down the window instead, tracking it like it was more important than whatever was happening in the room.
He only reacted when he heard his own name.
“Kim Taehyung.”
He lifted a hand lazily without opening his eyes. “Tragically, yes.”
A few students snickered. The teacher didn’t even blink.
“Second row. By the window.”
Taehyung opened one eye.
Second row.
By the window.
That was… closer to the front than he preferred. It meant teachers could see his face clearly enough to call on him. It meant fewer opportunities to disappear into the back of the room. It meant he might actually have to look like he was participating.
He stared at the ceiling for a long moment as if considering whether he could simply refuse.
Then he sighed like a martyr and stood up.
Half the class watched him, because half the class always watched him. Taehyung moved with the easy confidence of someone who knew he was being observed and considered it part of the day’s entertainment.
He slung his backpack over one shoulder and made his way through the rows, stepping around chairs, ignoring whispered comments.
When he reached the desk by the window, he stopped.
Someone was already there.
Jeon Jungkook.
Taehyung recognized him instantly in the same way you recognized a landmark when you’d walked past it a hundred times.
Jungkook sat with his posture straight, uniform neat, sleeves rolled cleanly to his elbows. He was writing in a notebook with a focused expression that made the classroom noise seem irrelevant. His pen moved steadily, like every stroke was planned.
He looked like the kind of person who actually knew what he was doing with his life.
Taehyung stared at him for a beat too long.
Then Jungkook looked up.
Their eyes met.
Jungkook’s gaze was calm. Observant. Not bored, not annoyed—just measuring, as if he was quietly taking inventory of a situation and deciding what to do with it.
Taehyung’s lips curved into a slow smile.
“Well,” he said, voice low enough to be just for them, as he dropped his backpack beside the desk. “This is going to be fun.”
He pulled the chair back and sat down.
The chair legs screeched softly on the floor, a small sound that made a few heads turn. Jungkook didn’t react. He returned to his notebook immediately, as if Taehyung hadn’t just landed beside him like a problem.
That was… unusual.
Most people had an immediate reaction to Taehyung. Teachers tightened. Students either laughed nervously or leaned away. Even friends tended to brace themselves, like being around him meant something was about to happen.
Jungkook simply kept writing.
Taehyung leaned his elbow on the desk and rested his cheek in his palm, studying him like a puzzle.
“You’re the famous basketball captain, right?” he asked.
No response.
Taehyung blinked. Tilted his head.
“Wow,” he said, leaning in a little. “You’re ignoring me already.”
Jungkook’s pen paused. It wasn’t dramatic—just a half-second stop, a slight shift of his hand. Then he looked up.
“You haven’t done anything yet,” Jungkook said evenly.
Taehyung’s eyebrows lifted. “Oh?”
“I’m waiting.”
The words were calm, but there was something in them—an edge tucked beneath the polite tone, like a door closing quietly.
Taehyung felt his smile sharpen.
“Experience?” he guessed.
“Unfortunately.”
Taehyung laughed softly and something warm flickered in his chest—not affection, obviously. Not that.
It was… interest. The same kind of interest he felt when someone finally played back instead of folding.
He shifted in his chair, turning toward Jungkook fully.
Up close, Jungkook looked even more composed. His uniform smelled faintly like laundry detergent, clean and crisp. There was a thin black sports band around his wrist, and when Jungkook rested his forearm on the desk, Taehyung noticed how strong his hands looked—steady, capable.
Taehyung reached forward without thinking much about it and took Jungkook’s pen.
Just plucked it right out of his fingers.
It wasn’t even subtle.
Jungkook looked down at the empty space where the pen had been. Then he looked at Taehyung.
The silence was immediate and heavy, like the air had remembered how to hold its breath.
“Give it back,” Jungkook said.
Taehyung twirled the pen between his fingers, slow and deliberate, enjoying the way Jungkook’s eyes followed the movement without moving his head.
“Or?” Taehyung offered.
Jungkook didn’t answer right away.
Instead, he watched Taehyung for a second longer—eyes steady, expression almost unreadable. And then his hand moved.
Fast.
His fingers closed around Taehyung’s wrist, firm enough to stop the pen’s motion instantly.
Taehyung froze.
It didn’t hurt. It wasn’t violent. It was controlled in a way that made it worse, because it meant Jungkook had done this before—had grabbed faster wrists, stopped faster impulses, handled situations without needing to raise his voice.
Their faces were closer now, close enough that Taehyung could see a faint crease between Jungkook’s brows, like the mildest sign of irritation.
Or focus.
“Taehyung,” Jungkook said quietly.
Taehyung blinked once, surprised by how his name sounded in Jungkook’s voice—low, steady, like a warning wrapped in calm.
“How do you know my name?” Taehyung asked, too quickly.
“Attendance list,” Jungkook replied and with a smooth motion, he took the pen out of Taehyung’s fingers.
Then he let go of Taehyung’s wrist.
Taehyung stared at his hand for a beat after the contact disappeared. His skin felt… normal. Nothing dramatic had happened. But the memory of Jungkook’s grip lingered like a pressure mark you couldn’t quite see.
He flexed his fingers slowly.
“Interesting,” Taehyung murmured.
Jungkook returned to writing.
“What is?” he asked, as if the conversation was a minor distraction he’d already filed away.
Taehyung leaned back in his chair and tilted his head, watching the line of Jungkook’s jaw as he looked down at the notebook.
“No one’s ever grabbed me that fast before.”
Jungkook’s pen paused again. This time, there was a fraction more of a reaction—just a tiny shift in his shoulders, like he was recalibrating his patience.
“Taehyung,” he said.
“Yes?” Taehyung’s voice came out too pleased.
“Stop.”
Taehyung’s grin widened.
“I literally just got here.”
A soft sound—almost a sigh, almost a laugh—escaped Jungkook like he hadn’t meant to let it out. He didn’t look up, but the corner of his mouth twitched, barely there, like a secret he was trying not to admit.
Taehyung caught it immediately.
Oh.
So Jungkook wasn’t immune. He was just… restrained.
That was even better.
The teacher began writing on the board and the class settled into reluctant silence, notebooks opening, pages flipping. The sound of chalk filled the room.
Taehyung should have pretended to take notes.
Instead, he watched Jungkook write.
Jungkook’s handwriting was neat. Clean. The kind of handwriting that looked like it belonged in a textbook. Every line was straight. Every symbol placed with precision.
Taehyung tapped his fingers lightly on the desk.
Jungkook ignored him.
Taehyung tapped again, closer to Jungkook’s notebook.
Jungkook’s pen continued moving, steady, as if Taehyung was background noise.
Taehyung leaned in. “Do you always act like you’re the only person in the room?”
Jungkook didn’t look at him. “Do you always talk during math?”
Taehyung smiled wider, delighted. “Only when I’m bored.”
“And are you bored?”
“I’m in math,” Taehyung said, like that answered everything.
Jungkook finally turned his head, just slightly, eyes landing on Taehyung with a calmness that should have felt dismissive but didn’t. It felt… attentive, which was worse.
“You’re going to get yourself in trouble,” Jungkook said, tone quiet.
Taehyung’s chest did that annoying little flicker again, like his body was reacting to Jungkook’s voice before his brain had agreed to it.
“I’m always in trouble,” Taehyung replied, leaning closer, voice dropping. “That’s my brand.”
Jungkook’s gaze held steady for a second too long.
And Taehyung noticed it then—not a smile, not a blush, nothing obvious.
Just the slightest change in Jungkook’s eyes, like something in him softened and tightened at the same time.
Like he was trying not to be amused.
Like he was trying not to be curious.
Taehyung’s grin turned wicked.
“Oh,” he whispered. “You do have reactions.”
Jungkook’s pen stopped.
He looked at Taehyung fully now, expression flat in the way teachers got right before they snapped—but Jungkook wasn’t a teacher. He was a student. A captain. Someone who wasn’t supposed to care about Taehyung’s chaos.
And yet.
“Listen,” Jungkook said quietly, “I don’t know what you’re trying to do—”
“I’m not trying,” Taehyung interrupted, eyes bright. “I’m succeeding.”
For a moment, there was only the sound of chalk on the board, the murmur of a student flipping a page, the faint hum of the city outside the window.
Then Jungkook leaned in, close enough that Taehyung could feel heat from him, not touching, but near.
“Don’t make this harder than it needs to be,” Jungkook murmured.
Taehyung’s breath caught so lightly he almost didn’t notice—until he did, and then it annoyed him.
He forced his smile to stay easy.
“Why?” he whispered back. “Are you struggling?”
Jungkook’s eyes narrowed.
Taehyung’s heart did something stupid again.
Jungkook sat back, picked up his pen and went back to writing as if he hadn’t just leaned in close enough to make Taehyung’s thoughts trip over themselves.
Taehyung stared at him for a long second, mouth slightly open, like he’d been interrupted mid-joke.
Then he slowly shut it.
Oh, this was going to be fun.
Not in the usual way—Taehyung had always been good at causing reactions, at pulling strings and watching people dance.
But Jungkook wasn’t dancing.
Jungkook was watching.
And somewhere under Taehyung’s satisfaction, something unfamiliar shifted—an awareness that felt like a hand closing around the back of his neck, steady and warm.
Taehyung glanced out the window.
Outside, the city kept moving. Cars slid through wet streets. People hurried under umbrellas even though the rain had already stopped. The world acted like nothing had changed.
But Taehyung felt like something had.
He looked back at Jungkook.
Jungkook was still writing, composed as ever.
Yet the line between his brows was faintly drawn, as if Taehyung had lodged himself into Jungkook’s concentration like a pebble in a shoe.
Taehyung’s grin returned, slower this time.
He leaned closer again, just enough to invade Jungkook’s space.
“You’re going to have to try harder than that,” Taehyung whispered, almost sweetly. “If you want me to behave.”
Jungkook didn’t look up.
But his voice came out low and steady, like he’d already decided something and wasn’t sure he liked it.
“Taehyung,” he said, “don’t test me.”
Taehyung’s smile widened like he’d just been handed permission.
“Why?” he asked softly.
And then, with a satisfied little tilt of his head, he added:
“Are you scared you’ll win?”
Jungkook’s pen stilled for the briefest moment.
And in that tiny pause, Taehyung swore he felt it—something real, something quiet, something that wasn’t annoyance.
Curiosity.
Maybe even the beginning of something Jungkook hadn’t planned for.
Taehyung sat back in his chair, pleased with himself, and finally—finally—opened his notebook.
He wrote the date at the top of the page with exaggerated care.
Then, beneath it, he scribbled one line only he would understand.
Jeon Jungkook. Interesting.
And outside the window, Seoul kept moving, unaware that two seats by the window had just become the most dangerous place in the room.
