Well, I just finished this drama and there are good things and bad things about it 1) the idea is good: I mean the story itself is really good and in the first episode it began really strong and with that mystery that hooked me up since the beginning, but since episode 2 and so on, it became a little weak, and not that well executed to me... it somehow lacked the mystery of the 1st episode and the story lost emotion... That's why I think that it is a good idea, it's a good story, but how they told the story wasn't that awesome. 2) Photography was Daebak!: That's what I loved the most about this drama, it was extremely well executed in that aspect, the camera work, the colors, the feeling that the visual aspect gives, was great. 3)Acting: Well I must say that Changmin did a really good job and to me was almost flawless, but Ga Young didn't do such a great acting, I mean it wasn't a bad one, but it wasn't that good. It just felt a little fake sometimes. But in general her and everybody else's acting was good. 4) Music: I loved the music used in this drama, each song fit so well with the entire feeling of the drama in general.
