For the most successful show in Netflix’s history, there is a lot in Squid Game that flies completely over anyone watching outside of where it comes from, South Korea.

One example: early on in the dystopian drama, which pits hundreds of desperate people against each other in a series of life-or-death games, there is a reference to a place called Yeouido. Korean viewers would recognise it as one of Seoul’s main financial districts, but one character reveals he’s never heard of it. It is a subtle point, and a mere second in the show, but it reinforces that this is a person from a lower class. Anyone not from Korea would miss it entirely.
