This series is a cracker. Far better than the American film. The cast are fantastic and the humour is on point. It's rare that a 16 episode series holds my attention the whole way though but this series delivered. The side plots are also interesting and do not distract from the main romance. The series succeeds in exploring adult themes in a youth drama. Lee Do Hyun who is excellent as the ML. He is totally convincing as an older man in a young man's body. All in all, is just good fun and will have you laughing and occasionally tearing up along the way.
