Okay these are all well known so if you haven't already read here we go:

Oldie:
The Beast Must Die

This is kinda new:

Definitely not my fave but it fits the topic

I want to throw this one out here too bc why not
Exotic Love
https://www.mangago.zone/read-manga/exotic_love/
Also Kiss Me Liar, our Jaegeng (Jinx), and some crazy manhuas which are full of angst too.
But tbh the ML's that obsessed from the start are the trend now guys so I would like to invite you to that side, such as:

https://www.mangago.zone/read-manga/forest_sea/
https://www.mangago.zone/read-manga/success_oriented_guide/

ngl I am a sucker and generally enjoy the plot "i don't care anyone in the world but now I'm obsessed and can't live without you and it's only you" plot but idk did i reach that age to question how could a person change to this degree bc this is bs at this point lol
