Be aware that the real story concludes with chapter 23. The following chapters are erroneously added from another (yaoi) work of the same title.
A pretty sweet love story with a kinda sad ending. It's not super depressing or anything. The major plot twist is just a reason to end it all not the way you might wish it to end in the beginning. I like most of the character development even if at times it seems a bit crazy. Well, they are teens, so it doesn't feel very unnatural. And the artwork is pretty good as well.
