Sorry! I don’t know the name but I also want to find out what that’s called too (￣▽￣;)
Minus the haunted house part, there’s a manga quite similar to it who’s also a horror/comedy/parody like manga

It may be the thing you search for... if not sorry >_<
Btw, did you try the horror tag on myreadingmanga? It may be there
So I kinda remembered it wrong The mc actually went there to end his life and the killer kind of saved his life. And the nerd and popular kids thing aren't really related to the mc but it's in the manga. Anyways I found it.

I'm trying again. Didn't really get answers last time ╮(￣▽￣)╭
Okay so I read this on myreadingmanga. The mc was a 'nerd' who got forced to enter a supposed haunted house by the 'popular' kids. There was this Jason alike guy living in there and killed all the 'popular' kids. I don't even know how to put this. This was a horror-cliche-comedy-parody kind of this.
So anyway, please tell me the name or send a link if this rings a bell. Thanks!
