It's one of the best series I've seen. At first it seemed boring and it took 3 episodes for the actual action to start, but it's a captivating series and I'm really glad that Seo was with Lee at the end. I did not expect such a change at the end. The plot twist was BIG. I would have liked it to have more episodes, but that's fine. I really want a second season. All the actors were handsome and very talented, only the cunning was in power throughout the film, something that made the film even more interesting. In the last episode, the scene with Yoo-hui and Hyung-joo like "let's get married" and he slapped her face was SO GOOD. I was really fooled in the beginning. However, I would have liked to have more scenes with them as a family, but we overlook it. Long story short, it's a series worth watching.
