_Nobody_

I'm trying to find this bl manhwa where mc had muted green hair half up and he got isekai'ed in a horror game (or realizes he's a character of a game idr) and tries to survive. The setting goes like a group of friends (all males) were going on a trip to somewhere but their car does down and they had up staying in a abandoned house but there's a killer on the loose. Mc is the first one becoming self aware, next is the ml (chestnut/dirty blonde hair) and we slowly see others too. Also mc goes around the house and collects tapes which were used to save the play or smth like this I don't remember honestly.
Sounds familiar to anyone?

Any manhwas where fmc is evil or morally grey?
