Sehun and Luhan. Everyone was envious of their friendship. One was never seen without the other except when they were put in different classes. Sehun was usually always seen with a hard cold facial expression but once Luhan was by his side, he was the cheerful, innocent dongsaeng. The 2 boys also hung out with a group of 10 other boys, Chanyeol, Baekhyun, Kris, Tao, Kyungsoo, Kai, Lay, Suho, Chen and Xiumin. The same thing was applied for each of the other boys (Chanyeol - Baekhyun, Kris - Tao, Kyungsoo - Kai, Lay - Suho, Chen - Xiumin). But what happens when one of the bestfriends starts to feel something towards the other? Will the other know? Would they still be friends? What is the line that divides a friendship and a relationship?
