Exo, have always been friends, but when graduation for the senpais approach thing's get scary for the Maknaes.  Based on Norwegian graduation (with russ and stuff) I was originaly going to add that but, it might be confusing for everyone else, so i decided against it. Everyone are stil russ though. i just won't be as obvious as before. Lay, Chen and Xiumin are Blue senpais. Chanyeol, Baekhyun and Suho are Red senpais.  Kai, D.O and Sehun are Juniors.  e
