Can anyone recommend yaoi mangas that have domestic abuse? Not necessarily rape. One of the characters (either seme or uke) can be a bit abusive (verbal/physical). Or one of the characters can be a little indifferent to his partner sometimes.

I mentioned domestic abuse earlier because I would like to see conflict in established relationships.

I would prefer a story where there is a happy ending. Any and all recommendations will be highly appreciated.

I can't say many come to mind, but Escape (KYUUGOU) is really good.

If I had a fantasy self, it'd be a tentacle monster.

I enjoyed Sabita Yoru Demo Koi wa Sasayaku, which does have a happy ending.

Doronuma is very good! U r gonna love it!

Very famous Harada has a lot BL that deals with heavy themes and I'm sure there's been some with abuse of the characters. Yoru to Asa no Uta in specific.

Double Mints ........ I don't remember if this has a happy ending!!

Sneaky Red I didn't read this one because I thought the summary was too fucked up lmao but maybe you'll like it 😛 I like other works by this mangaka.
