Possibly the worst drama I've ever actually finished, writing a review just to warn people don't watch this. The acting was pretty good, music was decent and the over arching storyline had it's strong points but was eventually completely ruined, if you want a drama to have an even remotely satisfying ending then this isn't for you. I gave it 3 instead of 1 star for story because it did have some moments where it began to considered the importance of mulling over the possibility of starting to get good
Throughout the drama they couldn't keep their plot points or rules straight, most of what happens supernatural/fantasy wise just doesn't make sense within their own rule structure, so frustrating watching it, if you want your drama to make sense, have a decent ending, or for your main character to have some semblance of emotion then this drama isn't for you
