Mistreatment

These are all famous ones so you probs read them
Black Lotus - makes my blood boil after every chapter
10 years where i loved you the most - pain and sadness after every chapter

manga from the author Harada sensei, physiological and covers some topics u probably would like, it does have bl though.

I read both of them already. They were really sad

I have read almost every manga from harada since last week. They were really sad and disturbing

“save me” is a good one i have more ill be back with links

This should be good, I hope you try this

"My fiancé is in love with my little sister"

I also Include the LN, pretty recommended the LN first before the manga
