When I read its story and saw it had just one episode, I decided to watch it immediately. I am glad I did. It was a pretty good episodic tale. I love stories which have ghosts in them and if it is a ghost played by Park Shin Hye, of course I had to see it! While the story is nothing extraordinary, it was pretty engrossing. It was well written and cute overall. It has the right amount of humor and emotions in it. The ending was particularly good. I really wish this was a full length drama. I hope they make something similar because that would be so good! The actors acted well and the musical score was also good. I really enjoyed watching this and wish that there could be more such kinds of one-episode dramas made. It is really worth a watch. Definitely recommended!
