Most of this mangas contain Cheating and rape . In all the mangas except one, the uke who's abused by seme often ends up with him. If you are looking for angsty mangas with tragedy you might also search for the tag Tragedy!

I already read that :( and it completely shattered me Ahahahhahaha i see that there's a part 2 of that but its fan made.
