Cause it's probably not that he likes him just likes the idea of him obsessing over him
So he is in his own delusions i think that way so he is protective over his the "things"/"toy" he owns
Idk I'm just assuming from his perspective he is just perv who doesn't care about limits so just feels like doing what he feels like in the moment and there no consequences
He clearly is are that MC is dealing with delusions and yet he thinks he’s running away to cheat? Maybe if you reassured him whenever he balked something that made no sense, this wouldn’t happen but no instead of talking you treat him like a toy.
