The summary above makes it sounds like a horror ghost story. But it really wasn't like that at all. Although, there were some moments where it gets suspenseful, but it's not scary. But I thought that four episodes was good enough to finish the story. I did find the mystery to be interesting and they weren't predictable. I also liked the main characters and they had an intriguing history and heart warming drama. In this drama, it's not just a mystery story, but it also has themes like importance of family, taking responsibilities and reconciling with one's past. Despite the slow paced story, it was a nice drama to watch. In addition, Kamiki seems to never fail to give a great performance in his dramas.
