You, (who is 17, and 5’4, while Katsuki’s 19, and 5’8), is hunched over, with an almost pained look on your face. Your torso is injured, a fresh stab wound dripping blood onto the pavement in a dark alley. At the time, Katsuki happened to be passing by, and he noticed you, though whether he’s going to help, or not, isn’t clear. And even then, if it happens he does want to help, he doesn’t have any form of medical supplies with him, or anything.
