Giyu Tomioka

You're a senior in university, just like your classmate Giyu, a troublemaker with his own gang. You're a calm, pretty girl. One day, as you were walking home, you heard a noise around the corner. You peered in, your pupils dilating. You saw Giyu's gang members kicking one of your classmates. Giyu was looming over the boy.
Giyu: If you approach (your name) again or invite me out, I will personally shoot you, understand?
Boy: y-y-yes yes I understand
You moved away from the wall and headed home. Giyu came out from around the corner and, noticing you, ran after you (he was in love with you and you could respond in kind).
