The song playing in the background, '일어나' (Rise Up / Get Up), is by Kim Gwang-seok, one of Korea's most beloved folk singers of the 1980s–90s. He died young in 1996 and is still deeply mourned; his music is shorthand in Korean dramas for warmth, nostalgia, and bittersweet feeling. The fact that Gwansik later tries to learn guitar specifically to play Kim Gwang-seok songs makes this opening track quietly meaningful.
The news anchor is referencing the real 2004 food-safety crisis in Korea when it was revealed that some manufacturers were filling mandu (만두, dumplings) with recycled, contaminated vegetable waste. The scandal caused nationwide panic and crashed dumpling sales overnight. The drama is set in that era, and the news clip shows how a small family mandu shop could be destroyed by an industry-wide scandal they had nothing to do with.
Aesum is ticking off a run of lucky breaks: deliveries during the 2002 FIFA World Cup (held in Korea and Japan, sparking massive street celebrations and food demand), the opening of duty-free shopping on Jeju Island which flooded the island with tourists, and the hit Korean TV drama '올인' (All In) which filmed on Jeju and turned it into a must-visit destination. All three happened within a couple of years of each other and transformed Jeju's local economy.
중고나라 (Joonggonara) is Korea's biggest second-hand trading community, which started as a Naver café in 2003 and became the go-to place for buying and selling used goods before apps like 당근마켓 took over. Aesum credits it with somehow helping to catch Cheol-yong — a nod to an earlier plot point — linking the family's good fortune to this very ordinary online platform.
In Korean tradition, a person's 기일 (anniversary of death) is marked with a ritual meal and family gathering, but parents of children who died young often observe the child's birthday instead — or as well — because the death anniversary feels too painful to mark. Aesum saying that Dongmyeong would want both parents there on his birthday reflects this deeply personal adaptation of ancestral memorial customs.
Aesum explains why the family never spoke of Dongmyeong: when grief is wrapped in guilt — 'I should not have let him go that day' — the memory can't soften into something to cherish. This idea sits within a broader Korean cultural tendency to avoid publicly expressing mourning for a lost child, as the pain is considered too raw and the guilt too personal to share even within the family.
The doctor diagnoses Gwansik with 다발성 골수종 (multiple myeloma), a cancer of plasma cells in the bone marrow. He explains it is a type of blood cancer — a distant relative of leukemia (백혈병). It is significant that Gwansik's symptoms were mistaken for rheumatoid arthritis for years; multiple myeloma causes bone pain and fatigue that can mimic joint disease, and late diagnosis is genuinely common.
Geummyeong's company 에버스터디 (EverStudy) is an online education platform, and she explicitly names 대치동 (Daechi-dong) in her speech — the Seoul neighbourhood that is the undisputed capital of Korea's private tutoring industry, packed with 학원 (hagwon, private academies). Her argument is that a girl from a remote island should have the same access to quality education as a child from Daechi-dong, which is a pointed social statement in Korean culture where education postcode determines life chances.
The news report covers the real opening of the 해녀박물관 (Haenyeo Museum) in Gujwa, Jeju, which opened in 2006. 해녀 (haenyeo) are the celebrated female free-divers of Jeju who harvest seafood without oxygen tanks; they are a UNESCO Intangible Cultural Heritage. Yangim's speech about 'living culture' and world heritage registration reflects the actual campaign that succeeded in 2016 — making this scene a quiet nod to the haenyeo's real-world victory.
The moment Aesum sits alone at Gwansik's grave with her finished poetry notebook, the soundtrack shifts to the Beatles' 'Yesterday' — a song entirely about longing for a past that can never return. It's a notable choice because the drama otherwise uses Korean folk and pop songs; the switch to this globally recognisable song of loss signals that Aesum's grief is universal, not just personal or culturally specific.
Young Aesum dreams of dressing like 엄앵란, a glamorous Korean actress and celebrity from the 1950s–70s, famous for her elegant and fashionable style. Mentioning Eom Aeng-ran's tailored suits as a life goal is a way of expressing how big and specific Aesum's girlhood ambitions were — and how far they were from the fishing-village life she was actually living.
