Firstly I thought this drama wasn't THAT good. I was sure it would be something kinda funny,cause of the fantasy in it, and the posters were not that impressive. I changed my mind since the first episode. It was the kind of drama that I wasn't looking for, but you can't do anything, because once you see the first ep it takes you into the characters world. I saw this while airing, from the second episode till the last, and I was waiting like a crazy for it every week. If a drama has this effect on me, it is good indeed. The storyline is simple but well done: a story of revenge, and justice with the saddest moments, the sweetest one and action at their right place. Even the romance is well balanced, and it never gets you annoyed. The love story between the characters is beautiful and makes your heart beats everytime. I loved the main couple, a pure love but also a strong one. I loved the characters because they are kinda smart in their mistakes. The cast was just perfect. Jong Suk and Bo Young are in their roles, you can see their differences very well. Sang Hyun too is very good as always making a role different from the one I knew him for. Woong In was just perfect in his role, I really could feel the tension while he was on screen. Also the music was awesome, I loved the sad/deep/funny/relaxing songs. What more can I say? The perfect drama. From the first the last episode. Everyone should see it!
