You can't compare such a masterpiece to this rape slop girl. In killing stalking the murderer and rapist (sangwoo) got what he deserved at the end,that's death the author didn't romanticize it. They showed the murder and rape as disgusting not as porn material like here. Plus killing stalking isn't a yaoi it's a psychological horror story. In this story the victim falls in love with his abuser and rapist and as a novel reader i can tell you 80% of the plot is rape and the victim suffering.
I’m not really comparing the stories nor plot of the two, more like how fucked up the characters are. This is merely a perspective of someone who has not read the novel, but has read a fee chapters of Killing stalking as i found it too much. The suffering of both mc in both stories are similar, they have been raped, and would often include violence during sex. That’s the comparison i was comparing to, hope this clears up my statement :)

toxic yaoi at its peak
