My list of psychological and others that had a good ending but characters background made me sad
Manhwa; it's completely toxic, but the characters do end up with each other: https://www.mangago.me/read-manga/paper_flower/

I'm tired of reading boring rainbow and sunshine bl with healthy relationships. I want something psychological, it can be a bit toxic too. As long as the story and characters are interesting everything goes! But i still want characters to end up together.
