안기부 (Angibu) stands for 국가안전기획부, the Agency for National Security Planning — South Korea's feared intelligence service from 1981 to 1999. In 1987, the year this drama is set, it had sweeping powers to arrest, interrogate, and surveil citizens with very little judicial oversight. Its agents appear throughout this episode as both investigators and enforcers.
강무 describes a secret scheme linking North Korean agents to South Korea's presidential election — a '대선 공작,' or election-manipulation operation. The 1987 presidential election was a real, historic contest that ended decades of military rule, so the idea that shadowy forces might rig it would have felt viscerally plausible to Korean viewers.
컵라면 (cup ramen) is the ultimate Korean convenience food — instant noodles in a disposable cup that just needs hot water. The fact that ten boxes of it are the government's opening offer for the release of thirty hostages is played for dark absurdity; it signals how little the authorities truly value the students inside.
광태 grumbles that releasing thirty hostages in exchange for ten boxes of cup ramyeon is a terrible deal — '밑지는 장사,' a losing business transaction. Koreans often frame negotiations in market terms this way, and his complaint doubles as dark comedy: a North Korean spy critiquing the South's bargaining skills like a street-vendor doing the math.
태일 mutters that he has ended up in '철창 신세' — literally 'the situation of iron bars,' meaning stuck somewhere like a prisoner. He is hiding in a cramped command tent to avoid press cameras, and the phrase captures both his physical frustration and his sense that the whole operation has become a cage of his own making.
The powerful figure on the phone refers to sitting together at '올림픽 개회식,' the Olympic opening ceremony. The 1988 Seoul Summer Olympics were the single biggest point of national pride for the authoritarian government of the time — hosting them was used to legitimize the regime on the world stage, which is why the election must be won at any cost.
The tinny music that plays is 국민 체조, the government-mandated group calisthenics broadcast on radio and television every morning in 1980s South Korea. Factories, schools, and offices were all expected to do it together. 승희 using it to keep the students healthy — and 수호 permitting it — is a small, surreal slice of ordinary Korean daily life playing out inside a hostage crisis.
분옥tells 수호 that he is the first person in her life who has ever taken her side — '내 편을 들어 준 사람.' In Korean social culture, having someone in your corner (내 편) carries deep emotional weight, especially for people from poor or marginalized backgrounds. For 분옥, who has no family connections or education, this moment of solidarity from an unexpected source is profoundly moving.
'출입금지' means No Entry or Off Limits. Finding this sign on a door inside the dormitory is a jarring sight for 수호 — it signals that someone has deliberately sealed off a space, likely to hide something or someone. In the cramped world of the besieged dorm, a locked-off room becomes one of the few places that still holds a secret.
수호 and 영로 establish a secret knock — '접선 암호,' a contact code used by spies and operatives to identify themselves safely. The word 접선 (jeopseon) specifically means a clandestine meeting or signal between undercover agents. It is bittersweet that the language of espionage has become the private language of their relationship.
강무 warns that 영로 — who already blames herself for the entire siege — will be pushed toward wanting to die once she learns her own father may be planning to kill everyone inside. The phrase '얼마나 죽고 싶겠어' (how much she must want to die) reflects the Korean cultural concept of 자책 (self-reproach) taken to its extreme, where personal guilt over collective harm is felt as a debt that can only be settled by one's own destruction.
