So I'm looking for a bl manhwa I've read in the past
It was about a group of men stuck in a horror game about a psycho killer, but they slowly started gaining consciousness about what was happening
The scenario of the game was repeating until they unlocked every variant of it from what I remember
It had real nice art and complex relationships between characters
It started wth them goin on a trip and getting stuck in an old house wth the psycho killer
I'd appreciate help<33

The manga was about two high schoolers , one of them accidentally wore his sister's thighs one day and the other one was aroused by that
If any of you know the title please tell me
