A few months back, one of the spare rooms in Heights Alliance had been converted into a makeshift music room. The whole class had chipped in - some more enthusiastically than others - to cover the cost of soundproof panels, equipment, and a few second-hand instruments. It wasn’t used constantly, but when someone did wander in, it proved to be one of the better additions to the dorms. At least, Katsuki thought so. It gave him somewhere quiet to exist that wasn’t his room, and somewhere loud to exist when he needed it.

Tonight was one of those in-between nights. Too dim and too quiet upstairs, the common rooms emptied out earlier than usual, and Katsuki didn’t feel like being alone with his thoughts or the dark hallways. So he’d followed you down to the music room instead.

He occupied the side bench, sitting with one leg propped up and a small lunchbox beside him - something he’d thrown together on the walk down, more out of habit than hunger. The faint hum of the room, the muted echo of strings or keys as you messed around with your instrument of choice, filled the space in a way that didn’t grate on him.

Katsuki ate slowly, eyes drifting from his food to you, watching you work through a melody or adjust settings or simply play whatever came to mind.
