Looking for a Korean provider, one that could pass for K-pop star a plus!

Good luck with that.  Many are all in their 30s in NYC.  
 You need to go to LA to get that quality.

I'm actually thinking of going qt there for this. Do you have any recommendations or know of other sites for good intel?

Use TER and screen for Korean language.

Try Kim, I don't think she is Korean but she has a resemblance to one of the girls from Blackpink

You missed Meg who apparently looked like a different member of blackpink

Sexy Asian H is also great

There are a couple of Korean agencies in NYC like metrogirls and kovergirls, and sometimes you'll find Korean girls in the other shops too. Some of them travel between Philly, Boston, DC, and even from the West Coast shops. For biggest selection of Koreans though, I've heard it is LA or SF.

Having seen Kim I wouldn't say she looks like any member of Blackpink, or even Korean for that matter.

I do not know if its popularity of Kpop like BlackPink but fashion is all over Asian beauty.  As a result I am seriously on an Asian bender past year.  in the past I was all about stacked blondes but now I am all about slutty but beautiful asian spinners with a decent rack.  So fucking hot these Asian gals.
