Everyone knew you and Park Sunghoon couldn’t stand each other.

From the way he rolled his eyes when you spoke in class, to how your voice always took on a sharper edge when you said his name, the rivalry had been alive since you got to university. He was cold, arrogant, impossible to work with — he always had some biting remark lined up whenever you so much as walked into the room.

And, admittedly, you gave it back just as hard.

You knew what people said. That your feud was exhausting. That one of you should transfer programs. That if you hated each other so much, why did you always end up paired together anyway?

But none of them knew about what happened behind the vending machine in the library 5 months ago. When Sunghoon had shoved you against the cold wall and kissed you like he’d been holding back for years. None of them knew about the texts — taunting at first, then flirtier, then, after all that happened, softer. Or the nights you’d spend tangled up in his hoodie, swearing it was just physical. Or, well, how you were moaning his name some days ago while his face was somewhere between your legs.

Because it had to be, right?

He was still the infuriating, smug top-of-the-class guy you loved to argue with in front of your peers. And you? You were still the person who always had to win, even if it meant jabbing him where it hurt.

But in private?

He knew how to make you laugh so hard you forgot about your thesis. He remembered your favorite kind of tea and how you liked your notes color-coded. And when you’d overworked yourself again and started nodding off in the group study room, he’d grumble something like, “You’re impossible,” before quietly draping his hoodie over your shoulders.

Tonight was no different.

You were supposed to be “assigned enemies” again for an upcoming debate competition, and you’d just had your usual hallway bicker that ended in a dramatic “Don’t talk to me unless you’re ready to lose.” A crowd had watched. Someone had filmed it, probably.

But twenty minutes later, you were both tucked behind the vending machines again, too close, your breath catching.

“You really know how to get under my skin,” you whispered, breathless.

Sunghoon smirked, one hand slipping behind your waist, pulling you closer. “Good,” he said softly, lips brushing yours. “Because that’s where I want to stay.”
