I don’t have a list for you, but I can link the stories I’ve read that fit your requirements! All of them are AMAZING, and instead of writing paragraphs praising them, I’ll just give you some warnings about the story (if any). Also, dont let my warnings completely turn you off from a story! The majority of them handle such topics with care.
https://www.mangago.me/read-manga/crush_and_burn/ There are frequent depictions of blood and violence, there’s child abuse, a size difference (which some may dislike, I personally don’t care), religion (though not to a large extent), and, unfortunately, technically rape. Without spoiling much, it was necessary so the Mc wouldn’t, you know, DIE, but even so, he did not consent. Oh and it’s a Yaoi
https://www.mangago.me/read-manga/kill_me_if_you_can/ Size difference, some depictions of blood and violence, and rape (not between the main couple). If you find this topic uncomfortable, then I suggest you don't read the side stories. The story, despite writing a perfectly healthy main couple, fails to treat the rape with the severity it deserves. They DID provide a reason why the rape wasn’t a “big deal” in story, but still. Yaoi btw
https://www.mangago.me/read-manga/i_don_t_want_to_be_a_magpie_bridge/ It’s been a minute since I’ve read this story, so I’m unsure, but there’s child abuse, stalking(?) (I don’t really remember all that well tbh), and not much else. RoFan btw
https://www.mangago.me/read-manga/paljae/ Murder? Idfk. This story may be a bit of a struggle for some to read due to how complex it is, though I do think it lightens up after the first few chapters. Shounen ai
https://www.mangago.me/read-manga/omniscient_reader_s_viewpoint/ Blood and violence, cannibalism, alludes to SA, and probably a few others. This story doesn’t shy away from the dark sides of humanity, especially in the earlier chapters. It handles these topics remarkably well though. Action
https://www.mangago.me/read-manga/my_mom_entered_a_contract_marriage_bored_corona_kids_version/ Pretty frequent depictions of child abuse, not much else though. People initially turned me off by saying the mc’s mother abused her, but it’s a lot more complex than that. RoFan
https://www.mangago.me/read-manga/how_to_survive_as_a_maid_in_a_horror_game/ A lot of murder ngl, also the relationship between the Mc and ml is mutually toxic, but it works. A bit of second hand embarrassment here and there but nothing too serious.
AGHHH I NEED TO GO TO BED
Okay I won’t warn you about the rest of these sorry
