In South Korea (and North Korea), ID and passport photos are taken at dedicated photo studios rather than at government offices. You buy a set of several identical prints, which you then physically attach — with glue — to application forms, residence cards, and other official documents. The photographer here rattles off exactly which agencies each copy is for, which is completely normal.
Seri introduces Jeong-hyeok as her 보디가드 (bodyguard) to explain away an authoritative North Korean soldier standing over a foreign visitor. The word is borrowed directly from English and is widely understood on both sides of the border, which is partly why she reaches for it — it's a neutral, internationally recognisable label that avoids awkward political questions.
Jeong-hyeok insists the two of them have a 상하 관계 (sang-ha gwan-gye), meaning a relationship defined by rank — him above, her below. In Korean society, even a small difference in age, job title, or institutional role is expected to shape how two people speak to and treat each other. His irritation is partly because calling him a bodyguard flips that hierarchy entirely.
Rooms in North Korean hotels used by foreigners are widely documented to contain hidden listening devices (도청 장치, listening bugs). Guests — especially those with any sensitivity — are aware of this and sometimes communicate by writing notes or running water to mask their voices, exactly as Jeong-hyeok does here. It is not a drama invention.
초상 휘장 (chosang hwijang) are the small metal lapel pins bearing portraits of Kim Il-sung and Kim Jong-il that North Korean citizens are required to wear on their left breast at all times in public. Not wearing one is a serious political offence. The 규찰대 (gyuchal-dae), a public-order patrol squad, enforces dress and conduct rules on the street — stopping people for short skirts, long hair, or missing badges, exactly as shown here.
치느님 is a playful portmanteau of 치킨 (fried chicken) + 하느님 (God), meaning something like "the divine lord Chicken." It captures how South Koreans feel about 치킨 — the crispy, double-fried style served at delivery chains — which is paired with beer so often that the combination (치맥, chi-maek) is essentially a national ritual. Seri has been craving exactly this taste of home.
첫눈 (cheotnun), the first snowfall of the season, carries a strong romantic superstition in South Korean popular culture: if you watch it fall with someone, your love for that person will come true. On the day of a first snow, messaging apps in Seoul famously overload as couples and people with crushes rush to make plans — a real phenomenon Seri mentions. The belief is reinforced by countless K-dramas and pop songs.
꽃제비 (kkotjebi) literally means "flower swallow" but refers to the homeless children and orphans who roamed North Korean streets during the catastrophic famine of the 1990s, scavenging for food. Cheol-gang uses the term about himself to signal that he grew up with nothing, owes loyalty to no institution, and has survived entirely through ruthless self-reliance — making his offer of "family" to his superior all the more chilling.
The song Seri sings, "찬 바람이 불면" (When the Cold Wind Blows), is a well-known Korean ballad about parting and longing. Its imagery of falling leaves and a cold wind sweeping someone away maps perfectly onto this farewell scene. The soldiers, who likely know the melody, fall silent — it is the kind of song that crosses the North-South cultural divide because its emotion is universally Korean.
