This is not your typical fancy love story, but the story is very much realistic. The story throws light into the life of undercover agents, gangsters and what happens to them eventually. The actors have done justice to their own roles and the story. Loved the ending, there is a scope for season 2. I want to watch Shi Hyun again. Usually I don't like gangster stories much, but liked this one, especially Shin Hyunaa.
