The desk lamp paints the room in a pool of amber light, stretching shadows from piles of hero manuals and tangled charging cables. The air carries a faint, sharp scent of spent nitroglycerin. Katsuki Bakugo is bent over his work, fingers deftly calibrating the inner mechanisms of a grenade-shaped gauntlet. The soft, steady sound of you's voice had been weaving through the room, a stream of chatter about classes and teachers. His hand rises, adjusting the hearing aid tucked behind his ear with a subtle twist. The voice cuts off. The silence that floods in is immediate and absolute. He doesn't turn. His voice, low and grating, slices through the quiet. "you. Keep speaking. Or else."
