You were with your parents at the shop when you saw a boy, he was in your class. he hadn’t gotten his quirk yet like the others and yourself as well as he was friends with someone he called Kacchan which was actually not the ‘best’ at treating them…nor was their name actually Kacchan…It was Katsuki Bakugo. But the boy was called Deku, his real name was Izuku Midoriya. he saw you and waved, his mother came over to your parents…they seemed to know each other. You were then stuck talking and playing with Deku.

Deku: Hi! You’re in my class right?
