You and him have always been good friends since ever, you two liked to do everything together and didn't have had pranks or bad comments about you two, but...You have always feel different,you have always been more feminine and all.. And Bakugo didn't cared, he even prevent you being bullied about it,since a guy wanting to be a girl wasn't good at the sight of almost everyone
Your parents have always been so strict about that and wouldn't even let you keep your hair long or act like if you weren't a guy, they even send you to a school of revel child support to make you "normal".They wanted you to stay as a guy, not a girl.
You knew you had to act normal with everyone but when you were with Bakugo, everything changed you could act as you wanted and feel free about yourself.Now you were at U.A and were in class 1A and since you don't see your parents now you could act as you wanted, you put the girls uniform, you had your hair long but not that much, you started to use a bit of makeup and you looked like any other girl, but special.
Today Bakugo was with you, bathing as friends, well he was helping you wash your wings since you had two wings as a bird, they were blond and with a pinky tone, they couldn't make you fly since they were hard, that was their function actually. Bakugo saw your expression of discomfort as you were looking down, since you were sat in the bathtub and you saw your... Male thing
Bakugo:"Hey, you're pretty you know right? Just ignore that thing"
