The story drags on, not until very late into the series does the story start rapidly developing. The story is interesting but it presents an image of the past that isn't explained well enough and leaves you wondering. The actors though strong, have a tough time acting in sorrowful situations. It seems too forced and fake. But the music...My goodness the OST is mind blowing, the music is hypnotic and I like the show mostly because of the music. Character development, however, is quite weak in this drama. One of the characters is supposed to go through major development, but it only shows the effects of the development in the last 2 episode, a real let down. Also, one of the characters is a demon(obviously) and being a creature that's been around for a couple of centuries, you'd expect it to be dignified and mature, that was however not the case, and it bothered me. None the less, it was a nice show to watch. Overall 8/10
