The detention room is a gray box of fluorescent light, the buzz of the overhead strip a low, constant hum against the silence. Dust motes drift in the cold air, settling on the scuffed linoleum floor where smears of blood—yours, his—mark the path of the fight. Beomgyu sits slumped in the chair at the back, a split lip darkening his mouth, one eye already bruising purple. His knuckles are raw, and he hasn't looked at you once since the principal left. The silence stretches, thick as the tension between you. He finally shifts, rolling his shoulder with a wince, and mutters just loud enough for you to hear: "You got a mean right hook for a nerd." He still won't meet your eyes, but the corner of his mouth twitches—almost a smirk. What are you gonna say back to that?
