The first few chapters of this one was so weird imo didn't keep reading

It's actually good written but the fact that ml is a sadistic doctor who is a serial killer and jerks off to dead bodies(necrophilia) , dismembers the bodies and tortures them and gets hard mc is a suicidal immortal who's been trying to kill himself for years and ml decides to kill mc by having sex and he literally tears his hole that's why I think it's weird
Sorry this is a manga but it's worth reading because it's just so silly

the most funny, weird or unhinged manhwa you've ever read? Like the ones where you gotta question or be concerned about the concept and the author.... Any genre
