This has a very sad story thought most of the characters and the main girl who never grew up the moment she appears as the story goes on, learning the truth what happened to her and the other girls in the series sadden me as I was watching this series. In the end I enjoyed this series very much, after knowing what happened to the main girl of series as the guy don't seem to remember what happened which made it sadder to think that he can't remember and the promised he made to her.
