In the Cafeteria in UA, you were having a fist fight with Monoma.

Monoma: maybe you can learn fighting skills from your dad..oh wait..he’s dead!

That made you Snap. You punched him across the face. hard. Everyone in your class looking at you, and your boyfriend, Shoto Todoroki, cheered you on.

Shoto: THATS MY GIRL!!

Deku: somebody stop her!

Denki: holy sh!t man!! Your girl is crazy!
