성게미역국 is seaweed soup made with fresh sea urchin roe, a delicacy found along Korea's coastlines. It is richer and more intensely flavored than the plain 미역국 (seaweed soup) commonly eaten on birthdays. Hwa-jeong offering this bowl is an act of quiet, motherly care — in Korean culture, warm soup given to someone who is upset carries the weight of a hug.
봉숭아 물 is a traditional practice of crushing garden balsam (봉숭아) petals and leaves, wrapping them on the fingertips overnight to stain nails a reddish-orange. Long before nail polish, this was a summer ritual especially beloved by girls and women. A popular folk belief says that if the color lasts until the first snow of winter, your first love will come true — which is exactly what Cho-hee's comment is teasing Hwa-jeong about.
Cho-hee's mother threatens that her brother will have her committed to a psychiatric facility — a stark sign of how same-sex feelings are still treated as an illness by some older or conservative Korean families. While South Korea has no law criminalizing homosexuality, there is no legal recognition of same-sex relationships either, and family shame (집안 망신) often drives extreme reactions like this one.
사랑니 literally means 'love tooth' — the Korean word for wisdom tooth. The name comes from the idea that these teeth emerge around the age when a person first experiences romantic love. Hye-jin's gentle advice to be courageous about pulling a painful hidden tooth is clearly a double meaning: she is talking to herself as much as her patient about the need to be honest with feelings that have been buried too long.
Eun-cheol mentions selling items on '오이마켓,' a nod to real peer-to-peer secondhand apps like 당근마켓 (Karrot Market) that became enormously popular in South Korea. These hyperlocal apps let neighbors buy and sell used goods, and meeting strangers in a dark alley at night for a cash transaction — while comically suspicious here — is a totally familiar scenario for Korean secondhand sellers.
Mi-seon references a well-known 1991 Korean pop ballad whose title translates as 'If You're Going to Write Love, Write It in Pencil' — meaning love can be erased and rewritten, so don't be reckless with it. Her point is the opposite: she wants their relationship written in 궁서체 (Gungseo typeface), the formal, serious calligraphy-style font that Koreans associate with official and sincere documents.
Mi-seon quotes a famous government family-planning slogan from the 1960s–70s, when Korea ran aggressive campaigns to limit births during rapid industrialization. Posters and slogans urging couples to have only two children and raise them well were plastered everywhere. The joke is that Eun-cheol, decades younger, has no idea this is an old state motto and not something Mi-seon just invented.
오늘 할아버지 기일 — today is the anniversary of Grandpa's death, called 기일 (忌日). On this day Korean families traditionally perform 제사, a ritual where food and drink are laid out on a table for the deceased's spirit, bows are performed, and the family shares the meal afterward. Jung-woo has set up the offerings himself, including attempting 홍동백서 (red fruits on the east, white fruits on the west), one of the formal table-arrangement rules Du-sik has to correct.
Seong-hyeon and Ji-won reminisce about a planned variety show built around Korean childhood monsters: the 빨간 마스크 (the Red Mask woman who asks if she's pretty), 홍콩 할매 (the Hong Kong Granny ghost), and 만득이 귀신 (the Mandeuk ghost). These figures spread through Korean schoolyards in the 1980s–90s as urban legends, much like Bloody Mary or Slender Man in Western culture, and remain touchstones of generational nostalgia.
Grandma Gam-ri speaks in 경상도 사투리 (Gyeongsang Province dialect), marked by distinctive vowel shifts and verb endings — '끈안아 줘' for '안아 줘' (hug her), '우태' for '후회' (regret). In Korean dramas, dialect-speaking elders carry a special moral authority; their blunt, warm advice lands differently than standard Seoul speech. Her instruction for Du-sik to go apologize and hug Hye-jin is the emotional turning point the village has been waiting for.
A 임상 교수 position at a Korean dental or medical school is a prestigious career step — part clinician, part academic, usually based at a university hospital in Seoul. For Hye-jin, who left a high-status Seoul life to open a small clinic in a seaside village, this call is a direct pull back to the life she walked away from. The timing, right as she and Du-sik are finally reaching each other, gives the moment its dramatic weight.
Nam-suk coins the term 홍익루머, a pun on 홍익인간 — the founding philosophy of Korea meaning 'broadly benefit humanity' — swapping 인간 (people) for 루머 (rumor, a loanword). She is playfully congratulating herself for spreading the lie that sent Yeong-guk rushing to Hwa-jeong's shop, which accidentally rekindled their relationship. It is a very Korean kind of self-satisfied wordplay that the whole room immediately gets.
서목태 are small black soybeans used in Korean folk medicine. Do-ha mentions brewing them as a decoction (달여서 마시는 것) to help with 어혈 (blood stasis) and paralysis — conditions her father has lived with after his accident. This detail quietly connects Du-sik's past as a financial worker to Do-ha's family tragedy before the confrontation explodes, showing he had been trying to make quiet amends through the herbal remedy he gave her.
