Why do kpop fans centre their worldview around korea so much?

I became a K-pop fan around 2017 but disengaged once it became mainstream and, in my view, lost some of its original appeal. Ever since the global explosion of Korean media like K-pop and K-dramas, I’ve noticed that some people act as if Korea is the pinnacle of culture or even human existence.

For example, when you see videos of people from a completely different ethnicity, there are always comments saying things like “if you look closely, this person looks like Heesung (for example),” or comparing them to a specific idol, even when the resemblance is barely there. I understand that people naturally compare others when there are similarities, but K-pop fans like these often seem to stretch it in every context to fit a "kpop appeal"

What exactly drives this tendency among some fans to treat K-pop as a universal framework for interpreting appearance and identity?
