남숙 calls Hye-jin a '도둑고양이' — literally a 'thief cat,' meaning someone who sneaks around like a stray stealing scraps. In Korean gossip culture, the phrase implies shameless, furtive behavior and lands as a sharp insult from a nosy neighbor rather than a playful tease.
Hye-jin's first hangover instinct is to ask for 헛개차, a herbal tea brewed from the Hovenia dulcis tree. It has been used in Korean folk medicine for centuries to help the liver process alcohol, and today ready-to-drink pouches are sold in every convenience store specifically marketed as a hangover cure.
Drunk Hye-jin hangs off a pull-up bar and shouts that she looks like Kim Yeon-a — South Korea's Olympic figure-skating gold medalist and one of the most beloved sports icons in the country's history. Comparing yourself to her is the ultimate humble-brag, which is exactly why it lands as comedy here.
The group heads to a 해장국집 — a restaurant that specializes in hangover soup, open from early morning for exactly this purpose. Du-sik ordered 선지 해장국, made with cubes of coagulated ox blood, which he argues is the definitive classic version; Hye-jin wanted a bone-broth style instead. Debating the 'correct' 해장국 is a beloved Korean morning-after ritual in itself.
The villagers reveal Du-sik graduated from Seoul National University's engineering school — 서울대 공대 — and entered at the top of his class. SNU is South Korea's most prestigious university, and its engineering college is among the hardest to enter; scoring first place there makes Du-sik's current life as a village odd-jobs man genuinely baffling to everyone around him.
감리 grandma mentions that the village hung a 현수막 (large fabric banner stretched across the road) when Du-sik got into Seoul National University. Stringing up such banners to announce a local child's college admission or national exam success is a genuine small-town tradition across Korea — a public celebration that belongs to the whole community, not just the family.
Mi-seon frames the village's unsolved secrets as a tidy list of three, which is a classic Korean storytelling device borrowed from folk tales — mysteries or life lessons almost always come in threes. The comic escalation (divorce gossip → missing years → a third secret she never finishes) plays on the audience knowing the formula.
Mi-seon jokingly calls Hye-jin a '유교 걸' — a 'Confucian girl' — meaning someone whose deeply ingrained sense of propriety and social hierarchy stops her from acting on impulse. It's a modern internet-slang label that teases people (usually women) who overthink their feelings through the lens of respectability and status.
Young I-jun writes 회자정리 거자필반 (會者定離 去者必返), a classical Chinese four-character proverb meaning 'those who meet are destined to part; those who leave will surely return.' These 사자성어 (four-character idioms rooted in Chinese classics) are still taught in Korean schools and used in everyday speech, so a sharp kid quoting one fluently is a small point of pride.
성현 threatens to call 백종원 to settle the fresh-versus-aged fish debate. Baek Jong-won is South Korea's most famous food entrepreneur and TV personality — his cooking shows and restaurant-rescue programs have made him the country's closest equivalent to a culinary supreme court. Dropping his name as an authority is an instant punchline any Korean viewer would recognize.
Hye-jin diagnoses Hwa-jeong with 근막 통증 (myofascial pain syndrome) caused by habitual jaw-clenching, where tension in the 교근 (masseter) or 측두근 (temporalis) muscles mimics a toothache. This is a real and common condition, and Hye-jin's calm, precise explanation here is the show's gentle reminder that she is an excellent dentist even when everything else in her life is chaotic.
Du-sik says '소나기 없는 인생이 어디 있겠어' — 'what kind of life has no sudden downpour?' 소나기 are the intense, short-lived summer rainstorms common in Korea, and they double as a metaphor for life's unavoidable troubles in literature going back to Hwang Sun-won's famous short story of the same name. Getting drenched together in the rain is a classic K-drama beat that borrows directly from that romantic tradition.
Someone asks Du-sik whether he still has the same nightmare, and he quietly says yes. This is the show's first direct hint at the emotional wound behind his mysterious five-year absence — the 'three mysteries of Gongjin' the villagers were gossiping about earlier. Korean dramas often use 악몽 (recurring bad dreams) as shorthand for unresolved trauma a character hasn't spoken aloud yet.
