This is the drama that got me hooked with Yoo Ah In and catch all of his other drama. I must say that the guy do really how to act, his acting was phenomenal, especially in this drama. The story, the plot are really interesting. All of the lines in this drama is so deep. Their story in the past life was pure and gold, each of them sacrificed their love for the sake of nation’s liberty and I do think that every one will do the same thing but it breaks my heart so much. The actors and actresses portrait their characters so well that I actually feel their pains (spoiler: ep 15). I don’t get why the rating of this drama is so low in Korea. To my opinion, this drama should get the same love and appreciation like Goblin. But overall, this is a good drama and I would recommended to everybody who want to watch something to entertain or kill their time
