I have to admit that I only watched this drama because of Lee Minho and in the end I don't regret watching it at all. Story? + The story is interesting and exciting. I forget to go to sleep because I was curious what would happen next in the drama. The characters are interesting and even though some of them didn't do only good things I liked them... - During the whole drama I hoped that some persons didn't die, well, in the end I still ended up crying but if I think about it, I think the ending makes the drama PERFECT although I didn't really LOVE it... Acting/ Cast? + I can't say anything on this matter. Lee Minho and Park Min Young showed great acting skills, as well as the remaining cast...I also liked the acting of Kim Sang Joong very much. The emotions seemed real and I forgot that this was just a drama and they were acting... Music? - I don't think the music was as good as everyone says. There were some songs whcih I didn't like or scenes where I thought that the music didn't match with the actions... + The second ending song which was also used in some scenes was really good. I liked it and it was perfect for all the cliffhangers at the end of the episodes. Rewatch? Even though I think this drama is really good and I could always rewatch some scenes, I think that all those long and complicated conversations would be annoying if you already know what will happen. Overall? A great drama with good music, an amazing story and wonderful actors...I think this drama is a MUST-WATCH, at least if you like Lee Minho or any of the other actors...
