I particularly enjoyed this drama, and since the previous review didn't give fair credit to it, I thought that I should write a review :) However, I do think that it might not be to everyone's palette and the best way to decide is to watch it :))
I felt that the drama was light and easy to enjoy in comparison to other secret agent dramas that I have seen! There was no great conspiracy, loads of secrecy, huge amount of fighting scenes, etc etc. I liked that the plot focused on a secret agent who becomes a bodyguard to an actor and still carries out his duties as an agent: it made the story work - of course very unrealistic but which drama isn't xD
I have to say the cast was great! All of the actors fit their characters and made the drama work. I really have to give kuddos to Park HaeJin's acting in this! His actions and facial reactions just brought the drama a kind of humour I really enjoy! And maybe because of this as well that it was nice to watch, and more light hearted than other secret agent dramas.
Of course, I did have a hard time to come in terms with Kim Min Jung's hair - seriously they cut her hair way to short!!
