wow. i've been reading it since the first chapter they updated. This manhwa has taken me on a psychological journey seen through the fucked up mind of yoonbum- the protagonist. There was a period of time when i became extremely absorbed in their twisted relationship but the more i thought about it, the more dark and rather unrealistic it became. And so i have put it on hold. Will come back to it some day. Definately recommend u to read it if u like murder, mindfuck and dark and fucked up stuff overall.
