Non zero sum
You might some in this list. https://www.mangago.zone/home/mangalist/2404942/
But novels out there are more disturbing. Like stories by Cari Waites(Gamble everything, Stealing innocent).
Basically I have this list where I put all the disgusting manhwa/ manga together. Lately I haven’t found the a very traumatic manga or manhwa to put in it. I kind of build tolerance to mangas/ manhwa like that. Using the things in my list usually involves grape, gang grape, murder or just a disturbing narrative! So if you have recommendations pls tell me. I really wanna Finnish this list so Becouse it’s bothering me
