Idea is totally fresh and execution is great. They put everything in place excellently, and this is the outcome. The storyline is almost perfect. The conflicts are over the places in the beginning, but it's needed and they resolve it quite well. Still I wonder how is Bit-Na's debt going lol. Character development for romance is a bit slow, but who cares? This is not mainly a romance and, who the hell will easily trust a Demon?!?

The thing that I want to highlight the most in this drama is the characters itself. Usually when it comes to have a demon as the main character, K-Dramas tend to mix it up with some dumb and irrational brain. However they made all of the demons (except Man-Do) to be as how demons should be. As a demon, Kang Bit-Na is really smart, ruthless, powerful and unstoppable. This depicts correctly about how she have truly lived for more than 500 years in the hell. Park Shin-Hye is definitely the star of this show, she brings the energy into it. The character of Man-Do is hilarious and sparks joy around the shows.

Unlike most K-Dramas, this series ends quite strong. Although it is quite a plothole (you get 3 years, but you choose to spend 2 years in an "exile" rather with someone you love???), but it is still a quite well, and not disappointing ending. In fact, they actually keep the story quality pretty consistent throughout the season. They have also prepared for next season, but I feel that they have to be careful as there isn't much more to explore.
