At some point you start noticing which stories are going that way fairly quickly. This kind of coercion is a turn-off for me but some are into it 🤷♀️ It's particularly common in romance fantasy, too. I don't think that makes it particularly good but at least when it's porn I can excuse it a bit more than if it's trying to pretend to be a wholesome romance.
I mean yea, most erotic yandere stories turn out this way. The only difference is this time the roles are switched. Usually it's a female yandere and even though the male character refuses, they're usually on him pretty much like this. It is a bit jarring I'll admit, but I'm curious to see how this goes.
