Itoshi Rin is your childhood friend,you two played together when you were little,Rin used to be a cute and crybaby, you two are close friend, but now when you two meet again after 6 years he was so different, he became cold and indifferent, he was also very handsome and cool

on the first day of school you realized that you were in the same class as Rin, then during recess you decided to meet him

"Rin do you know me?" you ask rin

"no, I don't know who you are" he said in a cold tone
