개차반 (gae-cha-ban) literally means 'dog's food scraps' — the kind of leftovers thrown to a street dog. Koreans use it to call someone a complete mess of a person, worthless or badly behaved. The show adopts it as Eun-chae's unofficial nickname around town, which tells you exactly how her neighbours see her.
울혈성 심부전 means congestive heart failure. In Korea, as elsewhere, it is a serious chronic condition where the heart can no longer pump efficiently. The doctor is telling Eun-chae that her heart is already so weakened that another surgery would kill her rather than save her — setting up the whole ticking-clock premise of the episode.
Street evangelists with loudspeakers are a very common sight in Korean city centres and market areas. They often warn passers-by about hell and the end times. Koreans tend to tune them out the way city dwellers ignore car alarms — Eun-chae's decision to actually argue back is what marks her as unusual (and entertaining) to the onlookers.
The date 1999년 12월 31일 (December 31, 1999) places this flashback squarely in the global millennium panic. Several Korean fringe religious groups predicted the world would end that night. Eun-chae's fury isn't really about theology — she's heartbroken that the apocalypse everyone else gets to experience might arrive after she's already gone.
통과의례 literally means 'rite of passage.' The senior officer is teasing the new civil servant Un-jeong that every rookie in the complaints office must eventually survive a truly unhinged 민원인 (minwon-in, complainant) on their own. Being harangued by the public is treated as an unofficial initiation into Korean public service life.
해성시청 is Haeseong City Hall. Korean city governments are divided into departments headed by 과장 (section chief) and 국장 (bureau director). Un-jeong calmly listing eleven Section Chief Kims and four Bureau Director Lees is both completely plausible — Korean surnames are highly concentrated — and a perfect deadpan way to shut down a bully.
돈지랄 (don-ji-ral) is a blunt, vulgar compound: 돈 (money) + 지랄 (a crude word for acting crazy or throwing a fit). Together it means throwing money around stupidly or wasting it on nonsense. Grandma is essentially saying that giving Eun-chae cash isn't generosity — it's throwing good money after bad.
칠순 (chilsun) is a person's 70th birthday, one of the most celebrated age milestones in Korean culture after 환갑 (60th). Families often throw big parties or take a special trip. The son's repeated mention of a '칠순 여행' — a birthday travel gift for his mother — signals both filial duty and the social pressure on adult children to mark this occasion properly.
As Eun-chae collapses, her mind goes to Kilimanjaro and the Northern Lights — two of the most iconic bucket-list destinations for young Koreans who consume travel content online. Their appearance here underlines that her dreams were very ordinary and human, which makes the moment land harder.
Un-jeong actually drove out to do the site inspection she was told was pointless — a callback to the earlier complaint about illegal dumping on private land. In Korea, 민원 (minwon) complaints to city hall are formally logged and followed up; her turning up here is by-the-book diligence, which is exactly what makes the timing so catastrophically bad for everyone else.
