This is a nice fantasy drama to watch - mysterious and funny . Pace is good and the story developed well.

The OST is simply amazing, almost as good as The Goblin. Two of the songs which I really liked are Yang Da Il's Only you and Heize's "Can You See My Heart(내 맘을 볼수 있나요)" . Many of the songs gave the drama very dreamy feel, further reminding the viewers that this is just a drama and can never happen in real life, hence, there is no need to keep our logic and rational, just go with the flow of the drama.

I love the main actress, Lee Ji-eun (as Jang Man-wol). She is so pretty in this drama! Of course Yeo Jin-goo ( Koo Chan-sung) is quite cute too, but I think Ji-eun kind of steals the spot light here. Her character is much more difficult to play as it spreads over several hundred years. In the fighting / combating scenes, she was quite good.

The plot is quite interesting , many strange things, not conventional and quite entertaining.

Would recommend to watch .
