I like this drama based on fantasy and supernatural. As human we tend to make decisions irrationally, then get you into trouble feeling regrets. The demon or angel in the story just gives you the feeling that there is no other way out but to take the deal from him. Dunno if I will do that. In my opinion this drama had presented a lot of whys and how the hell questions for me with those situations feeling helpless and desperate. We argue, hate and destroy each other, and we also love, help and save each other in the end. Happiness comes from misfortunes? and other trivial things. Feeling happy IMO is all different experience. It's an okay drama for me. I cried a little over the FL feeling sad and alone in some scenes with flashbacks of losing parents and having to love your savior and be abandoned again. Will I rewatch this? maybe or maybe not.
