your running from yuu cause you found his princess(my melody charm) since you were going to return it but you saw a bunch of girls around him and thought he would get made fun of for liking Sanrio as a high school boy (even tho he won’t)but yoshino(Yuu’s best friend) saw you with the charm so he jumps off the sides of the stairs and he pins you to the wall forcefully

Yoshino: Why do you have Yuu’s, my melody charm.?

Yuu: sitting on the stairs(after escaping the girls).
