The story tries to dwell on the psychological impact of a person's surroundings. After a few episodes, you can't help but want to know how it all ends as the ML is continued to be harassed. Some said this was not for the fainthearted and coward that I am I should have believed them. I should not have let my bias for Lee Dong Wook get the better of me.

Almost everyone contributed to condition of the ML in the end. It was not just the people in that fatal apartment. It really showed the premise that hell is other people and it's up to a person to look out for himself. I never thought Lee Dong Wook could ever look that creepy. He was still handsome and sexy but in a scary way. I would never be able to see him as an absolute hunk as I did in the past. Im Siwan was totally believeable as the ML who was struggling to overcome his obstacles. If only he received the help that he needed when he needed it, he wouldn't have ended up in that condition.

The story has some loopholes and is too insane to happen IRL. I also would have wanted some backstory on Munjo so I've rated it only 7/10. But the acting and music used were perfect for what this drama was depicting, how scary humans can be. I don't think I would ever rewatch this again. Call me a coward but this was too terrifying.
