https://www.mangago.me/read-manga/new_world_order/. Well I genuinely don't read much dark or horrifying ones.This don't have much graphics butttttt the whole vibe of this manhwa is lowkey very very dark and it's totally a clut based so u will feel it more the more u read next chapter
It's ongoing and only one season currently but u won't be disappointed by this
I LOVE THIS AUTHOR OMG!!! I haven’t read this work yet so I’m gonna get my filthy perverse grippers on it NOWWW thank you so much!!
https://www.mangago.me/read-manga/blind_play/ This one made me scared but idk if it will fit your criteria
Oughhh blind play you know ball oh my days
Does anyone have any ACTUALLY terrifying yaoi’s possibly? I’ve been trying to look but nothing seems quite appealing. I yearn to be scared. I beg.
