Hello, I'm looking for a novel I read a while back. I think it was a world hopping one and one of the arcs I can remember is the female protagonist (shes very op) of the novel took over the body of a girl who's boyfriend is a real scum, he invites a group of people including her to a hotel (?) under the guise that it was going to be a vacation trip (?) however, it was really a sketchy competition where the people there are competing to see who can escape and win the grand prize money (in the original the scum boyfriend wins and is the only one to survive). In the house/hotel there are ghosts and they each have a special item and each person gets one, I remember that the mc got a violin that can create tornados (?) while the boyfriend got a green hat that can summon ghosts. That's about it I hope someone will be able to help, thank you
