Pls help! I’m not sure what’s this novel is called. I can only remember an arc of it. It’s a quick wear novel. In this arc, the MC is a painter ghost in a mansion(or house I’m not sure ) and there is a group of ppl accidentally came to this place (and are trapped?) At first, this group of ppl believe that the MC is a person but after searching for the clue in the mansion for a while they realized that he is a painter that was imprisoned (to death?) by the owner of the mansion and his mentor is The person who introduced the painter to the owner.
oh wait although some plot points are different, you may want to check if it's a novel translated by kktranslations. should be a horror fic this possibly? https://www.novelupdates.com/series/i-rely-on-kisses-to-clear-survival-games/ Spoiler mc was kidnapped by a painter and the ml became a ghost with the painter's body
