동심회 (Dongsimhoe, lit. 'same-heart society') refers to the type of secretive old-boys network that shadowy political figures in 1980s Korea used to consolidate power. Membership was a ticket into the innermost circle of those grooming the next head of state. Being invited in was understood as a promise of future political protection — and loyalty.
육사 (Yuksa) is shorthand for the Korea Military Academy, whose tight-knit alumni bonds were a defining feature of 1980s political power. A '두더지' (mole) placed inside the academy was a long-term spy groomed by a faction leader. Calling someone his '주군' (lord/master) echoes the feudal loyalty language that real-life generals of that era used unironically.
'정을 통하다' is a formal-sounding phrase meaning to become sexually or romantically intimate with someone. In this scene it is used as an accusation: a North Korean operative fraternising with the daughter of the South's intelligence chief is framed as the ultimate ideological betrayal. The gravity of the charge carries the weight of a court-martial offence.
고스톱 (Go-Stop) is Korea's most popular card game, played with flower cards called hwatu. '짜고 치다' means to collude secretly before the game starts — so 'rigged go-stop' is a vivid idiom for any backroom fix. Eun Ae-ra uses it to say the entire hostage crisis looks like a pre-arranged show between the South Korean and North Korean sides.
행시 (행정고시, the Higher Civil Service Examination) was one of the hardest tests in Korea, gateway to top government posts. Passing it was considered a lifelong golden ticket — the ultimate proof of worth. Kwang-tae shouting it at armed commandos in a crisis is darkly comic: he is desperately asserting his social value at the worst possible moment.
Ae-ra extends the go-stop metaphor by calling the North Korean operatives mere '화투장' (individual flower cards) — disposable pieces in someone else's game. Calling a person a single playing card is a sharp insult implying they have no agency, just a tool to be played and discarded by the real players at the table.
This is a blunt Korean folk saying: a dog that eats filth can never break the habit. It is used to write off someone as incorrigibly low-class or corrupt, no matter how high they rise. Nam Tae-il uses it as a rhetorical weapon, suggesting that even the first lady shares this cynical view of people who started out as loyal attack dogs.
압구정 (Apgujeong) in Gangnam was the most glamorous address in 1980s Seoul — the epicentre of new money, luxury boutiques, and large prestige apartments. Citing an 80-평 (roughly 2,600 sq ft) flat there as a yardstick for obscene wealth would have been instantly recognisable to Korean viewers as the ultimate flex of the era.
A '도사' is a master diviner or folk sage, distinct from a mudang (shaman who performs rituals). Wealthy and powerful Koreans consulting a도사 for business or political decisions was — and still is — a real phenomenon. The scene satirises how Korea's elite mixed stock-market greed with supernatural belief, treating the fortune-teller's tip about a 'great benefactor from across the sea' as investment advice.
사모펀드 (private equity fund) was an exotic, barely-regulated concept for most Koreans in the late 1980s. Pairing it with a 스위스 비밀 계좌 (Swiss secret bank account) signals to the audience that Cheong-ya is running a classic confidence trick — promising VVIP-only access to a glamorous foreign fund. The Swiss bank angle was the era's ultimate signifier of untraceable wealth.
The North Korean chain of command shown here reflects the real structure of the 통전부 (United Front Department), which ran overseas operations. A 지령 (direct order) from above was legally and ideologically binding on agents — refusing it meant death for the operative's family back home. The midnight deadline is a device to compress the final standoff into a single night.
'공갈' literally means blackmail or bluffing, but colloquially it describes someone who fakes confidence to swindle people. 공갈순 is therefore a street nickname branding the person as a born grifter. The reveal that Linda Young and '공갈순' are the same woman — and that both Cheong-ya and Linda know each other's real identities — reframes their entire boutique encounter as two con artists sizing each other up.
