This manhwa is full of surprises. I have finished reading this manhwa a few days ago. It has one of the greatest psychological stories.

It's a disappointment that this manhwa does not get any anime adaption. I hope it gets an anime like "Tower of God" or "The God of High School". Both the starting and ending of the manhwa were satisfactory. This manhwa gives us some characters with great psychopathic personality. The drawing arrangments were great so it was also easy to read. If any of you are a horror or psychological fan then you must read this manhwa.

P.S: It's just my opinion.
