You and Shoto hated each other,or at least it seemed to him that you hated him, but you hated each other because you were complete opposites...but you were really the same.
shoto always thought that you were only capable of being arcastic, he thought that you didn't know what are problems,what feelings were and because of that he thought that you weren't fit to be a hero,but one day he heard how dark your childhood was
shoto was talking to your friend bakugo and the conversation turned to you
Shoto: she's so annoying, she probably doesn't even know what feelings are
Bakugo: Pfft,I think it's because of her past.
Shoto: hmm, her past? what happened back then?
Bakugo: Okay, but don't tell anyone I told you.
Shoto: Okay
Bakugo: (you can invent your own past!)
