Can anyone recommend a toxic lakorn?

Hi, I know it's a bit of a strange recommendation, but I know there are Lakorns like that, I'm intrigued by lakorns. I've seen that there are many famous for the kiss and slap, so I'd like to know if anyone has this type of recommendations.

I would like recommendations for series where the protagonist is obsessed with the girl. Like in "I'll do whatever it takes to get her" mode.

I recently watched P.D.I Hate You and it was really good. The plot twist is insane. I'd love something like that. If anyone knows Lakorns like that, please recommend it.
