The haenyeo (해녀) are singing '이어도사나,' a traditional work chant from Jeju Island sung while rowing out to the diving grounds. '이어도' is a mythical island paradise said to lie just beyond the horizon — a place where exhausted divers dream of rest. The chant kept the women's oars in rhythm and their spirits afloat.
That sharp, high-pitched whistle you hear when the women surface is called 숨비소리 (sumbi sori), literally 'breath sound.' After holding their breath for up to two minutes underwater, haenyeo exhale in this distinctive way to safely release CO₂ before inhaling again. It's so iconic that people on Jeju can recognise a haenyeo dive site just by sound.
Aesoon's poem is from a 백일장 (baek-il-jang), a traditional open-air poetry and prose competition held at schools and public events across Korea. Students write on a set theme, and judges award 장원 (first place) and 부장원 (runner-up). Winning even runner-up at a young age was a genuine mark of academic promise, which is why her mother is so furious it wasn't a full first prize.
Gwangnyeo tells Aesoon that '이방이 사또보다 잘나간다' — the 이방 (ibangs) outshines the 사또 (magistrate). In Joseon-era government, the 사또 was the official lord of a county, but the 이방 was his chief clerk who handled all the real day-to-day power. The saying means the number-two person often does more actual work than the figurehead — Gwangnyeo's way of putting a positive spin on being runner-up.
The teacher's surprised reaction to receiving brand-new bills is rooted in Korean gift-giving custom: presenting 신권 (fresh, uncirculated notes) signals special effort and respect, just as ironing your clothes before an important visit does. Getting them meant a trip to the bank specifically to exchange old notes — a small act that says 'you matter enough for this extra step.'
Gwangnyeo says she would not even tread on a teacher's shadow — this is a well-known Korean proverb (스승의 그림자도 밟지 않는다) expressing the Confucian reverence for educators. Teachers ranked just below parents in the traditional hierarchy of respect, so showing up with gifts and treating the visit like a formal audience was completely expected behaviour, not flattery.
The scene with the 무당 (mudang, female shaman) performing a 굿 (gut, ritual ceremony) is a traditional Jeju practice meant to negotiate with spirits on behalf of the sick or dying. The 요령 (yoryeong) hand bell you hear drives away malevolent spirits while calling benevolent ones. Jeju haenyeo had a particularly close relationship with shamanism because their livelihood literally depended on surviving the sea.
Gwangnyeo's instructions to Aesoon — leave this household, go to your uncle, don't become a servant — follow a real social pattern in mid-20th-century Korea. A widowed woman with no assets had almost no legal standing, and her children from a first marriage could easily end up as unpaid labour in a stepfather's extended family. Gwangnyeo is using her last breath to give her ten-year-old daughter a legal and social exit plan.
Gwangnyeo sings '웡이자랑,' the most beloved traditional lullaby of Jeju Island. '웡이' is a Jeju-dialect word for a baby, and '자랑' here comes from 'sleep well' rather than the standard Korean word for 'pride.' Generations of Jeju mothers sang this same song — hearing it in this moment connects Gwangnyeo's death to an unbroken line of women who loved and lost on this island.
양희은 (Yang Hee-eun) was the defining voice of 1970s Korean folk music, sometimes called the 'Korean Joan Baez.' Her gentle, melancholic songs were associated with college students and a quiet resistance to authoritarian culture. Playing her music under the bustling market scene anchors the drama firmly in the early-to-mid 1970s and signals that Aesoon's generation grew up with both hardship and romantic idealism.
