I started this drama because I had just finished 'The Guest' and wanted to watch another horror type of kdrama. This did not disappoint. While it is not exactly a horror it is a psychologically horrific drama that makes you frustrated, want to throttle not only the antagonists but also the main character, and makes you want run screaming from religious fanatics (if you didn’t already want to). It is highly addictive. I finished the show in about three days, but it is also draining. The show depicts a family that gets sucked into a religious cult and I thought it felt really realistic. The rewatch value is the lowest of all my ratings because of how draining the show is and how much you want to pull your hair out from all the things that happen that make you want to go into the tv and slap some sense into the characters. I will also say that the drama has some major themes that can trigger or be uncomfortable to watch such as bullying, suicide, murder, sexual assault. If you want to watch a mature drama that is addictive with great acting and see how brainwashing can not only scar but break people watch this. If you want to watch how people overcome trauma and fight past not only the people in their lives who try to control them but injustice as well, watch this. Also, because it is important for me to know and might be a factor in people’s decision to watch this the show does have a HEA but it takes a while to get there and there are a lot of painful events before we get there. The show doesn’t really have romance but what I found to be one of the most entertaining and enticing aspects was the friendship between the two ML’s. For me their relationship was one of the best to see. At the core of this show is the friendship of four boys and how doing the right thing can hurt but if you have the support and love of friends you stand a chance. I wish we could see the FL develop her friendship with the four boys more, but even so the drama was riveting especially since these boys could have abandoned the FL but despite everything they came through. The music was good but I do not find it all that memorable. It did fit the vibe of the series. Overall, great drama!
