개차반 literally means something like 'dog's food bowl mess' and is one of the more colourful ways Koreans call someone utterly worthless or disgraceful. It sits just below outright profanity in rudeness — strong enough to sting, common enough to appear on prime-time TV. The show uses it as Eun-chae's unofficial nickname around town.
울혈성 심부전 (ulhyeolseong simbujeon) is congestive heart failure, a condition where the heart can no longer pump strongly enough to meet the body's needs. In Korean medical dramas and real life, doctors often speak very directly to patients about prognosis, which can feel blunt to Western ears — the scene's tone is culturally normal rather than unusually harsh.
Evangelical street preachers with megaphones and sandwich boards are a fixture of Korean city life, especially around busy transit hubs. The specific date being shouted — 31 December 1999 — points to the real-life millennium doomsday panic that gripped parts of Korean Christianity in the late 1990s, when several fringe groups predicted the end of the world at Y2K. The drama is set in that era.
죠스바 is a shark-shaped red-bean and ice-cream popsicle that has been sold in Korea since 1974 — one of the country's most nostalgic snacks. Spotting two strangers eating the same obscure treat at the same moment is treated as a small, funny coincidence, the kind Koreans call 인연 (inyeon) — a fated connection.
The angry man recites Article 7, Clause 1 of the Korean Constitution, which states that public officials serve the entire citizenry and are accountable to the people. It's a go-to move by frustrated Korean citizens in 민원실 (minwonsil, the public complaints counter) — whipping out the exact legal text to shame a bureaucrat into action is a recognisable, almost comic trope.
Every Korean city and county office has a 민원실, a walk-in counter where citizens can file grievances about anything from illegal dumping to missing persons. It handles an enormous range of problems — far broader than a Western council complaints desk — which is why it attracts the full spectrum of local characters. Being assigned there is seen as a rite of passage for junior civil servants.
칠순 is the traditional celebration of a parent's 70th birthday, still a major family milestone in Korea. Historically, reaching 70 was rare enough to warrant a grand feast; today families mark it with a party, a group photo, and increasingly a trip abroad. Taking your mother to Hawaii or a resort for her 칠순 is considered a filial son's ultimate gesture — which is why the mention of it carries so much weight here.
부곡하와이 is a real hot-spring resort in South Gyeongsang Province that has been nicknamed 'Korea's Hawaii' since the 1970s because of its tropical-themed pools and gardens. For older Koreans, it was the aspirational domestic holiday destination before overseas travel became affordable. Suggesting 부곡하와이 instead of actual Hawaii is a gently comic downgrade.
분더킨더 is a transliteration of the German word Wunderkinder ('wonder children'), used internationally to describe exceptionally gifted child prodigies. Seeing it on a scientific project title signals that Dr Ha Won-do's experiments involved children — and that his work was framed in the language of elite European academia, a red flag the show plants quietly here.
Mount Kilimanjaro and the Northern Lights are two entries that appear repeatedly on Korean 버킷리스트 (bucket lists) as symbols of adventures that feel just out of reach. Mentioning them here — while Eun-chae is physically dying — makes the moment quietly devastating: she's not asking for much, just the big, beautiful world she never got to see.
Earlier in the episode the civil servant explained she could not act on the illegal-dumping complaint because the land is 사유지 — privately owned — and intervention without the owner's consent is legally impossible for local government. The irony of her now catching the complainant himself dumping on that same private land is the show paying off that bureaucratic deadlock as dark comedy.
사체 유기 means 'abandonment of a corpse' and is a specific criminal offence under Korean law, separate from the cause of death itself. Even if a person died of natural causes, concealing or moving the body without notifying authorities is a prosecutable act — which is exactly why the three characters are in such serious legal jeopardy despite not having harmed Eun-chae.
