I must admit that I started watching the drama just because Lee Seung Gi. I was not encouraged because I don´t like dramas that last more than an hour.
When I saw the first episode I fell in love, it was a great show.
In general it was a good drama, full of mystery, although I thought we would see more ghosts with deeper stories.

The characters are good, personally I liked the character of the zombie, it was so adorable ? , and the performances of the main characters were excellent.
Very good soundtrack and scenarios ... the only thing that I did not like at all, was the end.
The Korean dramas need to work a lot on the end, so hollow, I did not like it and I got angry because this series deserved a good ending. I still have the hope that an extra or special episode will come out showing us the final we deserve.
