The 안기부 (Angibu), formally the Agency for National Security Planning, was South Korea's powerful intelligence service — the equivalent of the CIA. In this era it operated with near-unchecked authority, able to order lethal force and suppress information with little oversight. The director's rank made him one of the most feared figures in the country.
동심회 (Dongshimhoe) is a fictional inner circle of power brokers shown in the drama. The name loosely means 'same-heart society.' Membership represents acceptance into the most elite and secretive tier of political influence — being invited in is a life-changing reward, not just a title.
육사 (Yuksa) is the Korea Military Academy, the country's most prestigious military school. A '두더지' (mole) planted there was a spy or loyalist embedded among cadets to build long-term intelligence networks. Graduates of 육사 formed the backbone of South Korea's military and political elite in this period, making personal bonds forged there extremely powerful.
고스톱 (Go-Stop) is South Korea's most popular traditional card game, played with flower cards called 화투 (hwatu). '짜고 치는 고스톱' — literally 'a go-stop game that's been fixed in advance' — is a well-worn idiom meaning a situation that looks like a contest but is secretly pre-arranged between the parties. Calling the hostage crisis this is a sharp accusation that both sides are in on it.
행시 (Haengsi) is short for 행정고시, the elite national civil-service examination. Passing it is one of the hardest and most coveted achievements in Korean society, guaranteeing a prestigious government career. The character's panicked claim that he passed it is a desperate bid for his life to be seen as valuable — essentially shouting 'I matter, don't shoot me!'
Here 화투장 (hwatu-jang) means a single playing card from the 화투 deck used in 고스톱. Calling the North Korean agents mere 'cards' in someone else's game strips them of agency — they are just pieces being played, not independent actors. The metaphor deepens the earlier accusation that the whole hostage crisis is a staged performance.
안기부 공작선 (gongjakson) were covert vessels used by the intelligence service for secret operations along the coast, including moving agents and contraband. Officials using these ships for personal smuggling to enrich themselves was a real form of corruption in this era, piggybacking private gain onto classified infrastructure.
The bell ringing and the cry '불우한 이웃을 도웁시다' ('Let's help our less fortunate neighbours') marks the Salvation Army's 자선냄비 (jasonnaembi), literally 'charity pot.' It appears every December in Korean city streets as a Christmas-season donation drive, much like the red-kettle campaign in the West. Its presence here signals the story is in its final days before the new year.
압구정 (Apgujeong) in Gangnam was the most fashionable and expensive new apartment district in 1980s Seoul. Measuring a fortune in terms of how many 압구정 flats it could buy was a very recognisable way to make an abstract number feel concrete and outrageous to Korean audiences — the neighbourhood had become shorthand for extreme wealth.
The 도사 (dosa) is a fortune-teller or spiritual master operating in the tradition of Korean folk shamanism (무속, musok). Wealthy and politically connected women consulting such figures for guidance on investments and personal fate was — and still is — a real and widespread practice in South Korea. The 도사's cryptic prediction about a 귀인 (influential benefactor arriving from overseas) is exactly the kind of phrasing these consultations produce.
사모 펀드 (samo peondeu) means 'private equity fund' — investments open only to a small group of wealthy individuals. Hong Kong was the hub of such funds for East Asian capital in this era, lending them an aura of international sophistication. The scheme청야sets up — a Hong Kong fund with 'only one spot left' — is a classic scarcity-pressure con, exploiting exactly the greed and FOMO that 미혜 has already shown.
Swiss bank secrecy laws made accounts at Swiss banks the gold standard for hiding wealth beyond the reach of governments in the Cold War era. For a Korean character to open one using someone else's identity and passport number is a dramatic signal that large sums of money are about to disappear permanently — and that whoever's name is on the account is about to be framed.
