삼천배 (samcheonbae) means performing three thousand full-body bows at a Buddhist temple — forehead to the floor, over and over. It can take ten or more hours and leaves devotees utterly exhausted. People undertake it as an act of desperate prayer, usually when begging for something they fear ordinary worship cannot deliver. The grandmother-in-law is scoffing that even this extreme penance won't solve the family's problem.
In Korean folk belief, dried red beans (팥, pat) repel evil spirits and bad luck. Shamans and elders scatter them around a person or space to drive away misfortune or a clinging ghost. Gwansik's grandmother is throwing beans at Aesun, framing her infertility as a spiritual contamination that needs to be cleansed — it is a ritual insult as much as a protective act.
잠녀 (jamnyeo) is the Jeju dialect word for what the rest of Korea calls 해녀 (haenyeo) — the famed free-diving women who harvest seafood by holding their breath to depths of ten metres or more. UNESCO recognised their culture in 2016. Traditionally girls could begin learning in very shallow water from childhood, which is why Kyeongja says the real divers started at six or seven; the elders are debating whether Geummyeong should be introduced to that life.
Gwangrye is Aesun's mother, who died from 숨병 — a lung disease associated with repeated cold-water diving. Her deathbed instruction to Aesun was never to do 물질 (mul-jil), the diving work. This explains why Gwansik's mother's plan to train Geummyeong as a diver hits Aesun like a betrayal of her own mother's sacrifice.
The TV public-service announcement — "a well-raised daughter beats ten sons" — comes from South Korea's 대한가족계획협회 (Korea Family Planning Association) campaigns of the 1970s–80s. The government was actively discouraging large families and son-preference through slogans like this. Hearing it play in the background while Aesun is berated for not producing a grandson sharpens the dark irony of her situation.
졸부 (jolbu) literally means someone who got rich suddenly without the breeding to match. Yongbeom's mother is deploying a classic Korean class put-down: implying that Geummyeong's ambition and her taste for nice things are signs of low origins rather than healthy drive. The insult stings because it echoes what Geummyeong's own childhood really looked like — but she refuses to accept the shame.
Geummyeong narrates in voiceover that she only now understands how fiercely her parents built their cramped, chaotic home into a 요새 (yosae) — a fortress — for her. In Korean family culture, the idea that parents' daily suffering is a form of protection and investment in the next generation is a deep social expectation. Geummyeong is finally reading what looked like poverty and conflict as an act of love.
A 장학금 (jang-hak-geum) is a scholarship or financial grant. Someone calling themselves 'Do Heejeong' has secretly paid three months of the family's rent. In Jeju, 도 (Do) is an uncommon surname, which is why Gwansik immediately runs through every female relative he can name — none of them fits. The mystery donor and the formal language "금 10,000원정" (exactly ten thousand won) give it the feel of an official charity, deepening the puzzle.
삼신할망 is the Korean goddess who presides over conception, birth and the early years of a child's life. Neighbours joking that the couple's diligence at night will surely summon her is a common folk way of talking about trying for a baby without saying so bluntly. The remark also connects back to the grandmother's whole subplot of prostrations and bean-scattering — everyone in the drama is praying to something for a grandchild.
An 어촌계 (eochon-gye) is a legally recognised fishing-village cooperative that controls who is allowed to fish or work in local waters. The captain's threat that his family controls the 어촌계장 (head of the co-op) in Dodong-ri means he can blacklist Gwansik from every boat in the village — a very real form of economic power in small coastal communities where no one outside the co-op can earn a living from the sea.
Geummyeong's closing voiceover says her father described Aesun as less like a 코스모스 (cosmos flower — delicate, pretty, swaying) and more like a 호루라기 (horuagi), a referee's whistle — sharp, loud, and impossible to ignore. It is a term of affection wrapped in humour: a woman who will absolutely blow the whistle on injustice even while dissolving in tears seconds later.
The distant male voice singing "찹쌀떡~ 메밀묵~" (chapssal-tteok, glutinous rice cake; memil-muk, buckwheat jelly) is a classic late-night street-vendor cry. These peddlers walked residential alleys after dark selling warm snacks, and their sing-song calls are a powerful nostalgic sound for Koreans of this era. Hearing it while Aesun weeps outside layers everyday ordinary life over the raw emotion of the scene.
Aesun asks Gwansik whether he would remarry (새장가 들다, literally 'take a new household') if she died. His answer — that he would rather wait to escort her properly and then follow — is a declaration rooted in the Korean ideal of 해로 (haero), growing old together until death. Saying he would 'send her off well and then follow' is his quiet, intimate way of vowing he belongs only to her.
