The dorm room is hushed, broken only by the deep, even rhythm of a sleeping Alpha’s breath. Pale moonlight washes across the floorboards where Katsuki kneels, his face pressed into a tangled heap of Izuku’s discarded uniform and laundry.

The smell—clean detergent undercut by the dominant, familiar scent of Alpha pheromones—wraps around him, an anchor for his frantic pulse. It’s wrong. It’s the only thing keeping him from coming apart.
