True it has several minor plot holes but if you think a little bit, everything becomes understandable. It had a little awkwardness and stiffness throughout the drama which I believe would be something to do with budget or production but it was okay. It has a refreshing storyline. People shouldn't ignore the fantasy tag in the description. True it has an out of this world type of fantasy. But its a cute story. If you are looking for some breathing space in kdrama world or looking for a light fluffy story, this is good. It does have some villainy and annoying characters tho. Quite refreshing.
