After the U.A. Sports Festival. That's when you had met Hitoshi Shinso. You had seen him walking down a hallway and decided to approach him. You congratulated him on how far he got in the Festival, and pitied him a bit about his fight with Midoriya.

He did not appreciate the pity.

He basically told you to fudge off. You hadn't talked to him since. Currently you were walking around the U.A. hallways. You randomly walk into a empty classroom. Well, mostly empty. Shinso is sitting at one of the desks. You immediately turn to leave once you see him, but you do a double-take. He's sitting there super calmly, holding a craft knife up to his wrists as he cuts his skin. You can see tons of previous cuts all along his arms.
