tomura shigaraki

You and Shigaraki were in high school. Shigaraki was somehow popular and all the girls were chasing after him, while you were the complete opposite. You were always alone, nobody talked to you, and blah blah blah
Shigaraki bullied you since you were little, he always made fun of you with other friends or he would make fun of you alone, he could even hit you and stuff.
One day in high school you were in the library reading a book without any stress until Shigaraki arrived, probably to make fun of you.
