The song playing in the restaurant is '일어나' (Rise Up) by Kim Gwang-seok, one of Korea's most beloved singer-songwriters who died in 1996. He is still deeply revered as a symbol of sincerity and folk-guitar romance, which is why Gwansik's later desire to learn guitar specifically to play Kim Gwang-seok's music carries so much weight.
The news anchor is referencing a real 2004 food safety crisis in Korea when it was discovered that some manufacturers were using recycled, contaminated ingredients in their dumplings (만두 mandu). The scandal caused nationwide panic and destroyed sales across the entire dumpling industry overnight, much like the avian flu did to fried-chicken restaurants a short time before.
중고나라 literally means 'Used-Goods Land' and was Korea's dominant secondhand marketplace in the early 2000s, operating mainly through online cafés before apps like 당근마켓 existed. Aesun is rattling off a list of lucky breaks that filled the dumpling shop's cash box, and a boost from 중고나라 traffic is one of them.
Aesun's comeback to Misuk is a reference to an old Korean soft-drink saying: Miranda (a local orange soda brand) and Fanta sell better when they're sitting right next to each other because customers compare them. Her point is that having a copycat competitor nearby actually drives more customers to the original.
The cheerful children's melody playing during Saebom's tantrum is the theme from '뽀뽀뽀,' a beloved KBS children's variety show that ran for decades from 1981. Nearly every Korean adult grew up watching it, so hearing it underneath a toddler meltdown is a gentle, ironic joke the show is making for the grown-ups in the audience.
The song Aesun hums — '자랑, 자랑, 웡이 자랑' — is a traditional Jeju Island lullaby. The word '웡이' is Jeju dialect for 'baby,' and the melody is one that would be instantly familiar to any islander. It returns at the episode's most emotional moments as a through-line connecting the family's roots to the island.
Gwansik and Aesun have come alone to Dongmyeong's grave the day before his 기일 (anniversary of death). In Korean tradition the 기일 is solemnly observed, and parents often visit a child's grave privately, separate from larger family gatherings. Gwansik notes the painful contrast: the graves of parents draw the whole family, but a child's grave leaves parents standing there alone.
The doctor explains that Gwansik has 다발성 골수종, a cancer of plasma cells in the bone marrow and a type of blood cancer. The critical detail is that its bone pain is almost identical to rheumatoid arthritis, so it can be misdiagnosed for years — exactly what happened here. It is treatable but generally not curable, which is why the family's reaction is so devastating.
A 백일장 is a traditional open-air poetry and prose competition held at schools and festivals across Korea. Winning first place (장원) is a serious honour — it marks someone as a genuinely gifted writer. Gwansik telling Geummyeong that Aesun was a 백일장 champion reframes everything: her gift was always real, and life just delayed it by four decades.
Geummyeong's company 에버스터디 is a fictional version of the real online education boom that transformed Korean private tutoring in the early 2000s. When high-speed internet reached ten million subscribers and portable media players (PMP) appeared, companies like Megastudy turned star 강사 (lecturers) into celebrities. The idea that a girl from Jeju who couldn't afford 대치동 (Seoul's elite tutoring district) lessons could now access the same teachers online was genuinely revolutionary.
The newscast shows the opening of the 해녀박물관 (Jeju Haenyeo Museum) in Gujwa-eup, which opened in real life in 2006. Yangim's speech about 'living culture' and global heritage registration foreshadows UNESCO's actual 2016 inscription of Jeju haenyeo diving culture on the Intangible Cultural Heritage list. Seeing Yangim on the broadcast is the show confirming that the grandmothers' world has been officially remembered.
The song that comes on TV is '어느 60대 노부부 이야기' (A Story of a Couple in Their 60s) performed by Im Young-woong, the trot singer who became a national sensation after winning the 2019 competition show '미스터 트롯.' The song is about an elderly couple's enduring love — the reason Aesun tears up is that Gwansik had been learning guitar specifically to play the original version by Kim Gwang-seok for her, and never got the chance.
In Korean literary culture, releasing a 시집 (poetry collection) through a recognised publisher officially makes someone a 시인 (poet) — it is not a title claimed casually. For a woman who dropped out of girls' high school, worked as a 식모 (live-in housemaid), sold fish at a market stall, and ran a dumpling shop, being called 시인 in her seventies is the full arc of the promise her husband made her on their wedding night.
