University dormitories in late-1980s Korea were spartan, and students hoarded snacks (과자, 라면, 등) in their rooms as a rare comfort. Rummaging through a dorm room for food during a crisis is both practical and darkly comedic — everyone knows the snack stash is real.
당 (糖) literally means 'sugar,' so 당 떨어진다 means someone's blood sugar has crashed — Korean shorthand for feeling faint from hunger or shock. It's a very common everyday expression, used here to point out that the elderly man urgently needs food, not to scold the person eating.
After the 1980 coup, the new military government rounded up tens of thousands of people — including labor activists, petty criminals, and anyone deemed 'anti-social' — and sent them to brutal military-run camps called 삼청교육대. Beatings, forced labor, and deaths were widely reported. The character's mention of her cousin dying there was a real fear shared by many Korean families of that era.
사시 is short for 사법시험, South Korea's notoriously difficult bar examination that used to be the only path to becoming a judge, prosecutor, or lawyer. Pass rates were sometimes below 2%, and candidates would study for years. The joke here is that even in the middle of a hostage crisis, one student's first concern is missing study time.
The mother on TV uses classic government-era anti-communist language — calling for the public to 'be strong' so spies won't dare attack. State broadcasters in the late 1980s regularly aired citizens voicing such sentiments; Snowdrop shows this was sometimes staged or coached by the authorities to boost the ruling party's image ahead of elections.
청와대 (Blue-Tiled House) was the official presidential residence and executive office in Seoul, equivalent to the White House. Saying someone 'has connections all the way to the Blue House' means they reach the very top of political power — here it signals just how deeply embedded Cheong-ya's handler is.
닭곰 is a North Korean term for a slow-simmered whole-chicken broth dish, essentially the northern cousin of 삼계탕 (ginseng chicken soup). South Koreans wouldn't recognise the word, which is why Kang-mu guesses 삼계탕 or 곰탕. The demand for 통닭 (whole fried chicken) alongside it adds absurdist comedy — a North Korean spy craving South Korean fried chicken.
In South Korea's 1980s authoritarian era, stoking fear of North Korean spies was a reliable tool for boosting the ruling party's vote. Seung-hee is explaining to the students that footage of frightened hostages would be broadcast to inflame 반공 의식 — the public's anti-communist sentiment — making voters rally behind the government, so the hostages are actually more useful alive and scared than freed.
In the late 1980s, South Korean intelligence officers (안기부 agents) were stationed inside major newspaper and broadcast newsrooms to suppress inconvenient stories. Han-na's plan to deliver a tape copy directly to a bureau chief's desk — bypassing the front door — reflects how journalists and dissidents actually tried to get censored information out during that period.
Young-ro keeping only her late mother's coffee as a keepsake touches on a sensitive social reality: in Korea, a stepparent discarding the deceased spouse's belongings was (and still is) a source of deep family tension. The fact that she 'fiercely protected' just this one tin shows how much her mother's memory means to her in a household where that memory wasn't welcome.
The slow, careful way Young-ro prepares the coffee over a small lamp echoes the Korean habit of treating 커피 — especially a loved one's favourite blend — as a small ceremony of comfort. In the 1980s, instant mix coffee (설탕·크림 혼합) was a beloved luxury in Korea; a tin passed down from a mother would be genuinely precious.
프락치 is a loanword from the Russian 'фракция' (faction), adopted into Korean during the Cold War to mean a secret informant planted inside a group. The term carries a strongly sinister connotation — being called a 프락치 was one of the gravest accusations someone could face in this era, implying betrayal from within.
