It was a nice drama but the best one. When you watch you can see the story, and what is coming. You can understand the stories of the main characters, but they don't show others characters' stories. In the end, you start to think about when it is finished. And a little bit boring.
Acting is good, they can show the characters' feelings. My favorite character is a shaman. He is hilarious.
I just finished this drama and I think I won't open it again. You can watch this drama if you finish all dramas and don't have anything to watch.
