Very interesting premise for a show, and they didn't use too many obligatory Korean cliches. Taecyon and Kim So Hyun were both very good. His character really developed as the show went along (as you would hope) and he went from being a complete loner to finally letting people into his life. She was kind of a stalker toward him early on, but not in an irritating way. She was innocent, but not immature, and very sweet. Kwon Yool does an excellent bad guy and was very creepy. I loved the relationship between the two main characters because they were both misfits in a way, but together they worked. I rated it lower because I'm all about the romance and it was lacking in this show, in order to make time for the story and all the ghosts. I also don't like open eye kisses (and one of them you could tell that they weren't actually even touching each other) and the ending was very weak.
