Any good toxic danmei to read? (mild spoiler only for SVSSS)

So for context, dont worry, I am an adult and fully aware of why toxic relaitonships and toxic people are a no go.

In similar sense I enjoy me a good crimi thriller without wanting to live it, I do enjoy a bit of a toxic relationship, without ever wanting to participate in one.

This idea came to me from reading SVSSS and admitting to myself that, while the OG Luo Binghe and Shen Jiu are horrible people, if the author gave them a terribly slow burn with somehow channeling the storyline of "we are both terrible people that deserve the worst - hence each other" - I d be still interested.

So I guess I m searching for a bit of a toxic relationship/obessive relationship but with a believable plot, happy ending is not mandatory. I d prefer for both parties to be terrible people not onyl one.. Also no underage, that is a hard no.

Thank you for any recommendations!!
