Basically, the average North Korean citizen isn’t likely to have access to Squid Game.
Kim Jong-un also recently called K-pop a “vicious cancer,” a move that was spurred by the fact that South Korean pop culture—of which Squid Game is a part—is becoming increasingly popular with younger North Koreans.
One of Squid Game’s fan-favorite characters, Kang Sae-byeok, is a North Korean defector whose main reason for entering the dystopian tournament is to earn money to bring her family to South Korea.
Sae-byeok also hides her North Korean accent when speaking to South Korean characters, and is derided as a “commie” or “spy” when other characters notice.
