Joon-hyung has been raised by his 큰엄마/큰아빠 (keun-eomma/keun-appa) — his father's older brother and that man's wife. In Korean family culture, the eldest paternal uncle's household traditionally carries a special responsibility, and these titles (literally 'big mother/big father') signal a formal, senior role within the extended family rather than a casual foster arrangement.
Joon-hyung's biological mother brings sneakers as her first gift after years of absence. In Korean culture, practical gifts — especially ones tied to what the recipient does every day — are a common way of expressing care that words cannot easily carry. Guessing his shoe size after a decade apart quietly shows how much she has thought about him.
Joon-hyung reveals he always knew the annual postcards and gifts came from his 큰엄마, not his birth mother. Sending gifts under someone else's name to spare a child pain is a form of 체면 (chemyeon) — protecting face and feelings for everyone involved. His aunt kept up the fiction for years purely to shield him.
Bok-joo's friend name-drops 김연아 (Kim Yuna), the figure-skating gold medallist who became one of the most recognised Koreans worldwide, and 손연재 (Son Yeon-jae), a rhythmic gymnastics star beloved for making a niche sport mainstream in Korea. The point is that weightlifting needs its own household-name athlete to attract public interest — and Bok-joo could be that person.
When Bok-joo's friend blurts out a dark joke about someone hanging from a Han River bridge, she immediately catches herself in horror. The Han River runs through central Seoul and appears constantly in Korean culture — in romantic drama scenes, in late-night food stalls on its banks, and, more sombrely, in public discourse about mental health crises. The friend's instant panic shows how loaded the reference is.
The actor at the convenience store drops two real Korean film titles: 부산행 (Train to Busan, 2016), a hugely popular zombie thriller, and 내부자들 (Inside Men, 2015), a gritty political crime film. Both were massive box-office hits, so namedropping them is his way of trying to sound impressive while admitting he only played tiny background roles.
Bok-joo quotes the proverb 열 손가락 깨물어 안 아픈 손가락 없다 — 'bite any of your ten fingers and they all hurt'. It means a parent cannot truly love one child less than another. She is gently nudging Joon-hyung to consider that his birth mother may be torn between two children, not choosing money over him.
Joon-hyung stops at a street stall to buy 군밤 (gun-bam), roasted chestnuts sold from small carts across Korea in autumn and winter. They are one of the most nostalgic cold-weather snacks — the smell alone signals 'home and warmth'. Bringing them to his 큰엄마 late at night, without being asked, is a quiet act of affection that speaks louder than any apology.
Bok-joo's father sends her off with 도라지청 (doraji-cheong, bellflower root syrup) for immunity and 홍삼즙 (hong-sam-jeup, red-ginseng extract) packets. Red ginseng especially is almost a national health obsession — parents routinely pack it for children leaving home, students sitting exams, and athletes going into intensive training. It is less a remedy than a physical expression of parental worry.
Bok-joo snaps to attention and delivers a formal 신고 (shin-go) — a military-style declaration — to her father and uncle before leaving for Taereung. South Korean athletes training at the national centre follow a quasi-military daily structure, and this comedic salute playfully mirrors that. It also draws on the compulsory military service that shapes how Koreans perform seriousness and respect.
