Forgotten Title Looking for QT bl horror

I'm looking for horror survival? Bl novel where Mc go in some weird storyline and do some kind of mission (i forgot).
In first mission, there is mission to seek some ghost groom's head?? and when Mc found it then danced with groom?? Also that groom is our Ml. - this was from different novel. God, everything is jumbled in my head.
In the end, Mc decides to stay with Ml and become npc of game worlds'.
In last part, new players come and curious ab graveyard (mc and ml became guards) and sees their guides are literally clinging to each other by being so lovey dovey with each other (Ml piggybacking Mc) and Ml being pretty much intimidating then when mission started they basically started almost doing everything and players were baffled.
Anyone knows this one pls give me some tips. I've read the novel pretty much years ago and possibly might be mixing with some other bc I read pretty much everything.
And in advance thanks ~*o*~

i just read it last week one of the clearance is finding the grooms head but I’m not sure if it’s the same one

 

Thanks for answering. My first part is def from this one. Haha, I pretty much mixed them with each other.

I think the graveyard part is from this one

 

Thank you so much

 

Lol when you read so many they become one story.
