Its been some time since I have been satisfied with a story of a show, not just in kdrama but in other variety as well such as Anime, Jdrama, Western shows. Most of the shows starts off strong but falls off in middle with rushed ending or show takes at least 5-6 episodes to hit. This show was neither, it started off good with no boring episodes and ended as good. The pace is as perfect as anyone wants. I think acting from some side character could be better but it wouldn’t impact the show too much. This show introduces lots of characters and by the end it covers everyone. The protagonist was very strong as well as antagonist. This show has very high rewatch value because of excellent pace and no boring episodes.
