you were in high school. Rin Itoshi was your classmate. You were often bullied and picked on, but you were used to it.

after school today, a group of boys (and others) cornered you. One boy pushed you to the floor, and another punched you in the stomach. They were about to kick you again, but Rin grabbed the boy by the shoulder. Because of his height and cold attitude, the boys soon left.

Rin: "Pfft."

Rin started to leave too.
