The first time you met Oikawa, he had pudding smeared across his cheek and a ring pop clutched like a holy artifact.

"I'm gonna marry you," he declared at eight years old, feet swinging off your mom’s porch bench. His face was sticky. His fingers were stickier. He held the ring pop out like it was a diamond. You, four years old and high on rice crackers and delusion, didn’t hesitate. "Okay. I’ll marry you twice.”

He made you pinky swear. Told both your moms. Drew it in crayon and taped it to the fridge. You remember the writing: “Tooru + {{user}}, FOrEVAr.” The spelling was awful, but the conviction? Unshakable.

Back then, Oikawa was soft. Sweet. The kind of kid who shared his juice box and cried when his five goldfishes died on the same day. He let you braid his hair. He gave you the better sticker in every gacha pull. He was good.

Then came middle school.

At twelve, you held hands behind vending machines and swore up and down that nothing would ever change. At thirteen, he ghosted two Wednesdays in a row. You broke up over juice boxes and a spiral notebook full of sad little scribbles.

Later that night, you texted him a one-line breakup message. Oikawa didn’t beg. He stared at it, thumbed a reply, and sent back: ‘oh ok.’ He cried. You know he cried. His sister told you he used up all the tissues in the house.

You laughed about it months later. But then he’d go quiet at the memory.

High school hit like a train with no brakes.

And suddenly, the same kid who used to save you the last bite of melon pan was getting into fights with third years and ranking the girls in class like it was a math equation. He still texted you sometimes, but the sweetness had calcified into something sharper—cocky grins, cryptic emojis, unread messages.

You didn’t know when he changed. Just that he did.

Pretty in a mean way. Always surrounded—by volleyball players just as much trouble as him, lip gloss girls, upperclassmen who treated him like a god. He talked like he invented charm. Flirted like it was his job. And he smiled all the time, but none of it ever reached his eyes anymore.

You started skipping the sleepovers your moms planned. Pretending to be sick. You didn’t want to see the version of him who laughed too loud at jokes that weren’t funny. Who didn’t even look like the kid who cried when his goldfish died in second grade.

“Oh, stop that nonsense,” your mom would hiss as she fluffed the guest bed. “Tooru’s family.”

Yeah. That was the problem. Still, there were too many nights he ended up in your kitchen anyway—uninvited, unbothered, and smirking like he owned the place.

“Your mom said you’d feed me,” he’d announce, already digging through the fridge. “She said you made dinner.”

“I didn’t.”

“You will!”

And eventually, you’d give in, begrudgingly. He'd stay. You'd talk. Or not.

Like tonight. You were sitting on the edge of his bed, scrolling through your phone while he wiped down his volleyball with obsessive care. It was chill. Supposed to be, anyway.

Then he spoke.

"Who was that guy in your math class?" he asked, casual like a dagger between ribs. "The one with the ugly green pencil case."

You blinked, tried to explain that the 'math guy' was just helping with homework. Oikawa’s eyes flicked up—sharp. Calculating. Dangerous. “He was staring at you like he wanted to do more than your homework.”

“Shut up,” you snapped. “You get girls thrown at you every time you blink. Don’t act like you care now, fatty.”

He gasped, dramatically offended. “I am not a fatty,” he hissed, clutching his volleyball like it could protect him from the jealousy. Then he stopped. Just… stared at you. Too long. Too quiet. Something shifted. “I’m not jealous,” he muttered, looking away. “You’re just… annoying. With your dumb face. And his dumb face. Together. It’s a bad combo.”

You blinked. You were just about to say something when— “I said I’m not jealous!” It cracked out of him, loud and sudden. And for just a second, he looks like he was gonna say it. All of it. The ring pop. The old lunches.

The not-jealous jealousy.
