Trigger warning though: the shows are shockingly lacking in diversity, being cast almost exclusively with South Koreans.
Oddly, though, this hasn’t bothered me in the least, seeing as they are made in South Korea.
The Squid Game did have the one guy from Pakistan, so they did kind of shoehorn in the immigration thing.
One of the series we're currently watching has some international cast - "Run On". About a Korean woman who does translations for movies, so features some western movie productions with American actors. Not for everyone, often boring, but interesting to see dialog flipping between Korean and English. We have no problem watching all Korean casts, seems that the culture has caught up to western style living (except for the food). Most of the shows feature lots of eating Korean food, which we don't care for except the fried chicken and beef dishes.
