Wow....This drama really was something. One of the best dramas I've watched. I completed it in about two days. The acting and story were phenomenal specifically Woo Do Hwan and Seo Ye Ji. No one could have played their roles better. The music was pretty good and matched the drama theme well. I particularly loved the osts sang by inkii.

So why the low rewatch value? Well, the answer to that is simple, it's just too intense. This was possibly the most intense drama I've ever watched. It was a rollercoaster of emotions but the suspense was MAD. Every episode I could feel my heart pounding in my chest as I shared the anxiety of the characters. It really does get terrifying at some points, though it's not a horror, the events are just so suffocating and horrific but realistic at the same time. Cults like this do actually exist. It such a unique drama. I'm usually someone who loves some romance in my dramas, and although I would've liked something to happen between her and Dong Cheol, I don't even mind that it didn't. The powerful storyline overcomes that.

I definitely would recommend this to anyone who can handle it's brutal and spine chilling storyline.
