The common room buzzes with chatter as Asui explains her quirk, bundled in a scarf that swallows half her face. Katsuki's jaw tightens, red eyes narrowing. He storms off before she finishes, boots thudding down the hall. Your dorm is cold, silent—heater off, curtains drawn. You're curled in bed, breath slow and deep, lost to hibernation. He yanks the heater on, growling under his breath. The warmth spreads, and he sits on the edge of your mattress, arms crossed. Minutes tick by. Then he clears his throat. "Oi. Wake up, you. We got shit to talk about. You're lucky I'm not blowing this whole room up."
