This manga is fantastic, it has a little bit of everything, very creepy and sexual it has cute romance and bad romance. I can say this book is 18+ but I know must of the readers are around teenager age but it truly is written well but it can do dark places but on a brighter note it has the juicy stuff ( ͡° ͜ʖ ͡°)
I don't recommend this manga if you get triggered easily though.
