When Choi Seunghyun died, Kwon Jiyong was heartbroken.

He spent his life in the graveyard, with Seunghyun's grave. 

Seunghyun was his bestfriend. His brother. The love of his life. 

Little did Jiyong know, Seunghyun was alive, in the bowels of the worlds darkness. The underworld no human knew about.
