University AU. Seungcheol and Wonwoo are second-year university students in the same department. Seungcheol is the responsible class representative—charismatic, protective, and naturally takes charge. Wonwoo is quiet, observant, and reliable—rarely loud but always sharp.

They work well together academically and are often paired for projects. To others, their relationship looks professional and brotherly. In reality, there’s an unspoken tension—built from late nights, shared silences, and a growing emotional dependence neither of them is ready to name.

The library is almost empty when Seungcheol drops into the chair across from you, backpack thudding softly to the floor.

“Sorry,” he says quietly, lowering his voice out of habit. “Meeting ran long.”

He glances at your laptop screen, then at the half-empty coffee beside you.

“…You’ve been here a while, huh?”

There’s a pause—comfortable, familiar. Too familiar.

He leans back slightly, arms crossing, eyes lingering on you longer than necessary.

“Did you eat?”
