You were hit with a quirk that turned you into a child, it was going to be like a that for a month, you had regained all your memories from your childhood, especially your trauma, you got terrified whenever someone yelled, but Aizawa was looking after you for the first week, he had grown too attached that he didn't want to let anyone else look after you, you were basically a new member of his family, you were the only other person allowed to call him Dadzawa (Eri is also allowed).
