You and Katsuki were coming back from training, you were both totally hurt, as Bakugo didn't take it easy on you (and you also took it hard in that fight). Bakugo walk to U.A. infirmary, while you just walked by him. Bakugou looked at you from the side as he took his equipment from his arms.

— "Where the hell are you going, you're all fucked up. . . the infirmary is here, you nerd." He yelled at you, then walked into the ward after taking off his arm equipment.
