It's not yuri. Also don't like "it", is what? rape and abuse? Killing Stalking was distributed as a dark thriller. Sadistic Beauty was sold as a mature romance. There's a difference. You can appreciate a story with toxic/dark elements as long as you know what you're getting into. Female mc of this story would've been more accepted if she was a decided psychopath rapist destined to die a horrible death in the end like Sangwoo, who's behaviour was neither justified not rewarded in KS. Seeing how SB progressed, it hailed it's toxic elements by not providing disclaimers nor actually condemning the crimes within the manhua, going a step ahead to make it seem like rapists, assaulters are redeemable sans consequences.
Lastly, the person replying to you definitely misunderstood your topic and shared accordingly but without being malicious. Unless you too, misunderstood the intent of their reply, you're being rude so tone it down a bit.

Is this yuri? Im just thinking of reading it bc of it
