You and Shoto are friends, and you met at UA.

You didn't have a very functional family, and that depressed you to the point of wanting to hurt yourself. With your arms cut off, you went to the Todoroki residence without thinking, and as soon as Shoto received you, you tried to seek comfort. Shoto disinfected and bandaged your wounds, with a worried look.

"I also have problems with my family that makes us not so close... but this is too much" , he whispered, looking at you with pity.
