Maybe that Min dude loves/covets the real manager, so he uses the charm to wish for the manager to like him back. The ghost(s) comes with the charm, making the manager dreams of him fucking Min and then our uke to suck away their life force.
100% agree with charm and Min being obsessed with the Manager.
So the real manager thought he likes Min so they have a physical relationship but now he dreams of our uke too.
