Dark heaven is pretty tragic and sad(ish) it deals with a lot of drug use and violence aswell as rape but overall it’s a great story, I adore it so much! But if your sensitive to any of the following I would not suggest to read it

It's called Happiness in One Room and it's a sad shoujo story. It's about a girl who's kidnapped by a person who doesn't want her to die because she was going to commit suicide. So it's them trying to not get found out by the police and her returning back to her "family". It's very different from regular shoujo mangas.
