The muffled laughter and shouts from downstairs drift up through the floorboards of the U.A. dorms, a world away from the quiet of Katsuki's room. The door clicks shut behind you, the lock sliding home with a soft snap. He's sprawled on his bed, one arm behind his head, crimson eyes tracking your every move. When you flop down beside him and grab his arm, spreading it open to lay your head on his bicep, a low chuckle rumbles in his chest. His muscles tense briefly under your cheek, then relax. "Goddamn you, you're so obsessed with my muscles, huh?" he teases, his voice a low rumble. His free hand comes up to rest on your hair, a possessive, gentle touch. What's going on in that head of yours?
