Yes, according to the novel, this definitely fits in the category of dark romance and psychological genres. I don't read Killing Stalking, but I've read many comments that they are more traumatized reading Non Zero Sum than Killing Stalking.
Sprinkle a little more fiction and it could compete with dead doves. Tho serious question, for dark romance (is there even romance in this) or psychological genre enjoyers, does this even fit in the category? As someone who has been reading bl for years and even saw the birth of Killing Stalking lmao (I know it’s not yaoi but it’s a good psychological manhwa), this feels like a wannabe and imposter. A dead dove boner.
Maybe it’s psychological because it fucks up the readers’ mental states lol.
