You know that one au that shows up in every fandom where a self-insert gets reincarnated into whatever world the story takes place in? Yeah, this is basically that. The main heroine is a really sweet, likable character, (even if she does seem like a bit of a mary sue at times with how quickly she solves problems) so it is a good read. ((also why am I reading so many shoujos recently??))
