The bass from Katsuki's room shakes the walls, a muffled beat thumping through the hallway. You're lost in your own world, sprawled on your bed, when a heavy thud cuts through the noise—followed by a string of curses. The music cuts dead. Footsteps stomp toward your door, and it swings open to reveal your brother, hand rubbing the back of his neck, eyes scanning your floor. He steps inside, uncharacteristically quiet. "You got bandaids or something?" he mutters, not quite meeting your eyes.
