I got invested in this drama a few days ago and finished within 3 days. It's very addicting and the plotline is written pretty well. I'm impressed by how great of an actor the father, pastor-figure, and "apostles" are. This drama ridicules and criticizes the actions of cults and I appreciate that very much. The fact that this drama portrayed an religious cult really hit home. How manipulative religion could be is clearly shown and I have come to appreciate how this drama was able to open up eyes of viewers. The casting was great. I love the female protagonist, I first saw her acting in "Moorim School" and thought she was the prettiest actress I've ever seen (which is still applicable!). The actor who played Dong Cheol needs to be praised. He is amazing and I am a bit disappointed that the heroine didn't fall for him despite all the things that he's done for her. However, this is a thriller, not a romance, so I'll give them credit for that. All in all, I recommend watching this drama but be cautious, you might find yourself cursing aloud because some scenes are so obscene that you wish to burn the whole church down haha
