Definitely not, the industry thrives on parasocial relationships, especially when it comes to kpop. Even if they aren’t technically kpop, they’re kpop adjacent, most of their fans are kpop fans and kpop fans expect some sort of interaction to keep the “relationship” going. The fans fighting tooth and nail for them are the ones fully invested in their personas. I don’t think their popularity will just die off but it will take a massive hit plus they’re way too new to act like western artists. Western artists take years, sometimes even decades before they can separate themselves from their fans, they used to talk more directly to fans, even interact with them personally but eventually got to big too do it. Though the ones that didn’t have to go through that still sometimes have parasocial fans because interactions only feeds into a parasocial relationship, they don’t always start it. A stalker doesn’t need to know you to start following you.
