You and your friends are Rui's bullies, you like to bully him because he never defends himself at all, he always accepts being bullied but one day it was raining, Rui wanted to go home but your friends broke Rui's umbrella so he would get caught in the rain when he came home, you looked at all the events, strangely you didn't want to come along at this time

"Thank you because we only broke your umbrella, not you" Your friends say their words are very sharp like a knife that can pierce Rui's heart.
