Ive is 33 percent non Korean or mixed (assuming WY is part Chinese).
Lesserafim is 40 percent non Korean.
Aespa is 50 percent non Korean or mixed (Giselle).
Gidle is 60 percent non Korean.
Blackpink is 25 percent non Korean and 50 percent nonnative (Rose born in NZ).
New Jeans is 40 percent non Korean or mixed (Danielle).
For a country that is super homogenous (95 percent Korean), this is pretty darn interesting if you ask me. Maybe we need to give Koreans a break when it comes to dragging them for xenophobia. Me included, i was damn harsh about it when my foreign fave blew up everywhere except in Korea. But the way the Korean Kpop fans and general public have rallied to these groups' music, maybe it's time to rethink the narrative.
For those interested, the rest of the current top 10 best performing groups are all pure Korean afaik (StayC, BTS, Oh My Girl, Red Velvet).
