I've been looking for a good kdrama to watch for a while, and I found it in this show. Every aspect of it has nothing to reproach itself with, the acting is of a high standard, which makes the whole story even more exciting. There is no moment of boredom, in every episode something happens and the story is incredibly interesting and also unpredictable. Music included in this show really fits to the storyline and the only thing I wish was more presented is closer relationship of Ryu Sung Joon and Jo Eun Ki. However I totally recommend waching it and I guarantee you will not regret it at all.
