@Xystus no, it's been hinted on a previous chapter that the boyfriend is slowly turning into an evil spirit the longer he remains there, one that wants to take over a body.
His girlfriend misunderstood the 'I want your body' before as consensual handholding, but I'm curious how it'll pan out with the friend.
@IShallReadTheHeavens As much as I wouldn't want to see that. It's probably not NTR, since being cucked is all about intent. Since the intent isn't there it's likely fine... Maybe...
@Diciannove44 seems like he's turning into an evil spirit over time. There is probably a reason ghosts aren't meant to linger and we are seeing it's effects on him first hand.
