Story: Can I just tell you that this has been the best mystery drama I have ever watched. Honestly, the plot, as far as I know, isn't like anything I've seen before and it's just so exciting to watch. You do die a little bit from all of he tension build up sometimes but that is what is enjoyable since you never really know what to expect.

Acting/Cast: Like, do I even need to say anything about the cast? They are all so talented and complete ~visuals~, I have no complaints. They did such a good job portraying their characters. Truly splendid.

Music: The music was honestly something that really enhanced the drama experience. It went with the occasion and always made the scenes better while keeping it simple and not overbearing the scene.

Re-watch Value: The only reason why I score it with a low re-watch value is because since the whole drama is about a mystery. So once you finish the drama the first time, you already know all the twists and turn the drama takes and you also already know all of the identities of the "bad guys". So, in it's original purpose to build up tension, the drama wouldn't do that anymore since you already know the plot.
