The haenyeo (해녀) women divers sing 이어도사나 as they work, a traditional Jeju rowing and diving chant. '이어도' is a mythical island paradise believed to lie beyond the horizon — a place where exhausted divers find rest. The chant helped women keep rhythm, calm their nerves, and cope with the danger of deep free-diving.
The eerie whistling exhale you hear from the water is called 숨비소리 (sumbisori), the signature sound a haenyeo makes when she surfaces after a long dive. By forcefully pushing air out through pursed lips, she resets her breathing fast so she can dive again within seconds. Locals say you can hear it across the water from far away.
The older diver appeals to the group to help support a sick colleague using the phrase 십시일반 (simsii-ilban) — 'ten spoons make one bowl.' It is a deeply rooted Korean idea that each person contributes a little so the whole community survives. Among haenyeo, this mutual aid was literally a matter of life and death, since an injured diver could no longer earn her own income.
Gwang-rye says she would rather be born a cow than a haenyeo. Haenyeo dove in icy water year-round wearing only thin cotton suits (물옷) until wetsuits arrived in the 1970s. Many developed '숨병' — a chronic lung condition caused by decades of breath-hold diving — and worked until their bodies simply gave out. The joke about a cow's life being easier reflects genuine bitterness about how little the divers earned relative to the danger.
Gwang-rye wonders aloud whether even Han Seok-bong could write as well as Ae-sun. Han Seok-bong (한석봉, 1543–1605) is the most famous calligrapher in Korean history, celebrated in a beloved folktale where his mother tests his brushwork in the dark. His name is shorthand in Korean for supreme talent with a pen, the way 'Mozart' might be used in English.
Gwang-rye comforts Ae-sun by saying 'the 이방 (i-bang) was more powerful than the 사또 (sato).' In the Joseon-era local government, the sato was the appointed magistrate, but the i-bang was the career bureaucrat who handled all the actual paperwork and knew every local secret. Koreans still use this saying to mean that the number-two role often has more real influence than the nominal top job.
Gwang-rye tells Ae-sun not to let the teacher smell the sea salt on her, invoking the old Korean proverb '스승의 그림자도 밟지 않는다' — 'do not step even on your teacher's shadow.' The saying comes from Confucian tradition and expresses the extreme reverence owed to a teacher, placing them just below parents and the king. Bringing a gift and dressing up was Gwang-rye's way of showing that respect in practice.
The woman shaking a 요령 (yoryeong — a small ritual bell) and muttering prayers is a 무당 (mudang), a female shaman. Jeju Island has its own shamanic tradition called 심방 (simbang), distinct from mainland practice. Families hired a mudang to perform a 굿 (gut) ritual when someone was gravely ill — appealing to gods and ancestors to intervene — because illness was understood as a spiritual imbalance as much as a physical one.
Gwang-rye sings '웡이 자랑' to her children, a traditional Jeju lullaby. The words roughly mean 'sleep well, our baby,' and mention a black dog (검동개) — a guardian figure who chases away bad dreams. The Jeju dialect makes it sound quite different from mainland Korean lullabies, and hearing it sung here underlines that this family is rooted in Jeju's specific folk culture.
Ae-sun's stepfather recites the opening lines of Kim So-wol's poem '진달래꽃' (Azalea Flowers, 1922) — one of the most memorised poems in the Korean language. He is quoting it slightly wrong in his excitement, which is the joke. Kim So-wol studied at a school connected to literature programs, so the stepfather is daydreaming that Ae-sun will follow in that tradition and he will fund her college dreams.
The newspaper headline about singer Yun Bok-hee and her miniskirt refers to a real 1967 scandal. When Yun returned from the United States wearing a miniskirt, it sparked a national debate about Western influence and 'decadent' fashion. The government eventually launched morality police who measured women's hemlines on the street. The TV news clippings frame the drama firmly in late-1960s Korea, a time of rapid modernisation and intense social policing.
Gwan-sik's grandmother warns that 'a mother's fate passes to her daughter,' invoking the belief that a woman's 팔자 (palja — destiny written at birth) can be inherited. Because Ae-sun's mother died young and was said to be 'haunted,' the grandmother fears Ae-sun carries the same ill fortune. This fatalistic view of women's destiny was common in mid-20th-century Korea and is one of the beliefs the drama sets up Ae-sun to defy.
