사리원 (Sariwon) is the capital of North Hwanghae Province, one of the larger cities outside Pyongyang. Because the drama is set in a rural border area, it makes sense that Sariwon — roughly 50 km south of Pyongyang — is the nearest city with a real hospital. Distance and road conditions in the North make this a genuine crisis, not a minor inconvenience.
Seri shouts that her favourite film is 'Mad Max: Fury Road' right before flooring the accelerator. '분노의 질주' is the Korean title of the Fast & Furious franchise (literally 'furious driving'), so she is name-dropping two of the most famous high-speed action movies in the world to psych herself and Gwang-bum up — and to warn him about her driving style.
Ok-geum calls Myeong-eun a '왕싸가지' — 싸가지 is blunt slang for someone with no manners or basic decency, and 왕 ('king/great') intensifies it to the maximum level. It is a genuinely harsh insult in Korean, roughly 'an absolutely insufferable brat.' The village women use it freely among themselves, which tells us they feel completely at home passing judgment on this Pyongyang outsider.
Ok-geum casually explains that because the electricity comes and goes, the fridge is used mainly as a 장식용 (decoration/display item) — shelving for books and clothes rather than for keeping food cold. This detail, played for laughs, reflects a real adaptation strategy documented among North Korean households in areas with unreliable power supply.
The young woman proudly introduces herself as '평양 최고의 아미' — the best ARMY (BTS fan) in Pyongyang. ARMY is the official name of BTS's global fandom. Possession of K-pop content is technically illegal in North Korea and can carry serious penalties, so her confidence is played as darkly comic. The drama has repeatedly shown that South Korean pop culture quietly circulates through the North on USB drives despite the ban.
The dress-shop owner gasps that smuggling a South Korean wedding magazine could land him in '아오지' (Aoji). Aoji is a coal-mining town in North Hamgyong Province historically synonymous with the harshest political labour camps — the name functions in Korean as shorthand for the worst possible exile or punishment, the way 'Siberia' works in Russian. His one-word threat captures exactly how risky the favour he is doing really is.
Seri tells Sang-woo that years ago she travelled to Switzerland when she no longer wanted to be alive, but realised mid-journey that she wanted to live — and a piece of piano music she heard there felt like the universe telling her to hold on. This is the emotional origin of the mysterious melody that has appeared throughout the episode. Korean dramas frequently use a character's suicidal crisis point as backstory to show how far they have grown.
