Not really.

Onlyfans is more or less a strip club. It is not (just) about seeing titties. It is about "the fantasy". Ask any stripper and the best possible "gimmick" is to be "working my way through (grad/law/nursing/whatever) school" since that lets clients feel like they are "saving" you.

And, on a surface level, that is similar. Pop Idol better not have a boyfriend because she is a permanent virgin and blah blah blah.

But that is where it ends. Because the guy who starts getting overly possessive of a stripper/sex worker/OF model/whatever? We, as a society, think they have issues and there is usually a support structure to get them away from the person they are going to stalk.

Whereas with k-pop (and, to a somewhat lesser extent, j-pop and the like): The support structure encourages that mindset and punishes the performer for daring to ruin "the fantasy". And, as can be seen here and every other time this happens, "society" encourages that.

And... South Korea is so fucked that it makes Japan look like a good place to be a woman. Like, it is a genuine problem to the point that voice actresses have gotten "cancelled" because someone thought they made a rude gesture that insults men.
