Sehun blinked slowly, imprinting the image of the back of Luhan's head on the inside of his eyelids. Luhan was leaving. He was leaving Sehun behind. He was leaving Sehun behind while he walked away with a piece of his heart. 

"Hyung..." Sehun'a broken call carried over the crowd to Luhan's ears. But he didn't turn back. 

It wasn't because he didn't want to look and Sehun. Oh he did! He so badly wanted to see at him one last time. 

But he didn't want Sehun to see the tears running down his face.
