Everything down to the music is great. This isn’t your typical love story type of k drama that’s for sure. It’s one of a kind that features a lot of suspense. This also has some of the best acting I’ve ever seen. I don’t want to give it away but you really believe these characters are played by two completely different actors in this series. It does take some paying attention to follow but it’s worth it. Once you connect the dots you realize what any amazing thriller it is. And it’s got the right amount of humor as well.
