사리원 (Sariwon) is the capital of South Hwanghae Province, about 50 km south of Pyongyang. It is a real mid-sized North Korean city with actual hospitals, which is why Gwang-beom knows there is one nearby. Mentioning a specific city name like this grounds the drama in genuine North Korean geography.
세리 shouts that her favourite film is 'Mad Max: Fury Road' — known in Korean as '매드맥스: 분노의 질주' — right before she floors the accelerator. South Koreans are avid cinema-goers and Hollywood blockbusters are widely known, so the reference lands as a quick character joke. In North Korea, however, Hollywood films are forbidden, making the line doubly funny because Gwang-beom has no idea what she is talking about.
낙하산 (literally 'parachute') is a very common Korean expression for someone who is dropped into a position through political connections rather than merit — the equivalent of 'a political plant' or 'a nepotism hire.' The coach uses it to describe the reserve player who was forced onto the roster from above, and everyone in the room immediately understands the complaint without further explanation.
천생연분 (天生緣分) means 'a match made in heaven' or 'fated partners' — the idea that two people were destined for each other since before birth. The nurse uses it teasingly because Seri and Jeong-hyeok share the same rare blood type, which she reads as a cosmic sign. The phrase comes up constantly in Korean dramas, poetry, and everyday conversation when people want to describe a couple who seem perfectly suited.
싸가지 is Korean slang for someone with zero manners or basic decency, and 왕- (王, 'king') is a prefix that cranks any adjective to the maximum — so 왕싸가지 means roughly 'the rudest person alive.' It is one of the more colourful informal insults in everyday Korean speech. Ok-geum uses it the moment she recognises Myeong-eun, signalling that the two women's clash is going to be spectacular.
Frequent, unscheduled power cuts (정전) are a daily reality in North Korean cities outside Pyongyang. The neighbours' casual explanation — that a fifth-floor flat is ideal precisely because the elevator will often stop dead and you'd have to climb — is presented as perfectly normal, not a complaint. It is an authentic detail that North Korean defector accounts consistently describe.
장마당 (jangmadang) are the informal street markets that became a lifeline in North Korea after the famines of the 1990s. Dan tells Seung-jun to visit an '앱 장마당' — a physical market stall where vendors install apps or games onto your phone for a small fee, because there is no public internet or official app store. This is a real phenomenon: North Koreans use a domestic intranet called 광명 (Kwangmyong), so software is traded on USB drives and memory cards at market stalls.
아미 (ARMY) is the official name for BTS fans worldwide. The young woman proudly introduces herself as 'Pyongyang's top ARMY,' which is played as an absurdist joke because South Korean pop music (한류 콘텐츠) is strictly banned in North Korea and possession can carry serious punishment. The scene gently pokes at how Korean Wave content quietly spreads across the border anyway, a subject that South Korean audiences know from real news reports.
호적법 제90조 인정 사망 (認定死亡) is a provision of Korean family-registry law that allows a court or authority to formally declare someone dead when there is no body but strong evidence — such as a serious accident with no survivors found. Jeung-pyeong invokes it to transfer corporate control, which Korean viewers recognise instantly as a legal manoeuvre to push the shareholder vote forward before Seri can return.
아오지 (Aoji) refers to the coal mines in North Hamgyong Province that were historically associated with the harshest political prison camps in North Korea. Saying someone will be 'sent to Aoji' is shorthand for the most severe punishment imaginable — exile to brutal forced labour. The dress shop owner uses it as a darkly comic way of saying he would be severely punished just for selling a wedding dress, which gives a sense of how tightly controlled private commerce still is.
Seri describes travelling to Switzerland years ago when she no longer wanted to be alive, framing it as wanting to see beautiful scenery one last time. She then clarifies she wanted to stop living but did not actually want to die — and that a piece of music she heard felt like an answer, telling her it was okay to keep going. This is portrayed as a turning point of self-realisation rather than an active crisis, but the scene directly describes past suicidal ideation.
