Gwansik panics because childbirth in earlier decades carried real danger, especially outside cities with limited medical access. The baby is already nicknamed 무쇠 (musoe) — meaning 'iron' or 'cast iron' — a tough, sturdy name parents give a newborn to will the child into surviving. Nicknaming a fragile baby something powerful is a long-standing Korean folk custom meant to ward off misfortune.
Geummyeong lists piano lessons, ballet, brand-name shoes, and even an 오피스텔 (officetel — a small studio-style apartment) as the baseline for raising a child properly. This reflects a very real pressure in Korean society where parents feel expected to fund private tutoring (학원, hagwon), extracurriculars, and eventually housing for their children. The debate about whether only the wealthy should have children echoes an ongoing national conversation about Korea's falling birth rate.
'경찰청 사람들' (Police Agency People) was a hugely popular real-crime documentary series that aired on MBC in the 1990s. Gyeok quotes it to make a point: con artists always line up plausible-sounding details — a golf course here, a hospital there — to make their pitch airtight, exactly the way the show illustrated how scam victims were reeled in step by step.
Gyeok quotes a Korean proverb: even an ox that has lost its calf is spared the plow. It means you do not burden someone who is already deep in grief. She is explaining why she never once blamed Aesun for the death of her baby Dongmyeong — she gave her daughter-in-law that same wordless mercy a farmer shows a grieving animal.
흥남 부두 (Heungnam Pier) is one of the most emotional landmarks in Korean collective memory — the site of a massive 1950 evacuation during the Korean War where roughly 100,000 civilian refugees were loaded onto ships fleeing the advancing Chinese army. Calling someone who is dramatically rushing off with a baby on their back a 'Heungnam pier departure' is a sarcastic but deeply resonant way of saying they are making a scene worthy of a wartime exodus.
중고나라 (Junggonara, literally 'secondhand land') began as a Naver café community in the early 2000s where people listed used goods to sell or trade — think of it as Korea's eBay/Craigslist hybrid before smartphone apps existed. It later became the platform 당근마켓 (Karrot Market) would eventually overtake. The show uses it as a wry plot device: the stolen antique porcelain is caught because the thief tried to offload it there.
번개탄 (beon-gaetan) refers to compressed charcoal briquettes widely used for Korean barbecue grills. In Korea during the late 1990s and 2000s, burning them in an enclosed space became a commonly reported method in suicide attempts and deaths, frequently covered in the news. The character is recounting past thoughts of ending her life and the specific options she mentally weighed against the fear of being photographed.
햇반 (Hetbahn) is CJ's brand of pre-cooked, microwaveable rice that became a household staple from the late 1990s onward. For a parent who spent decades boiling rice from scratch as an act of care, saying '햇반이 효도한다' — 'Hetbahn does the filial duty now' — is a bittersweet joke: their grown children no longer need a mother's rice pot, so a convenience-store shelf is doing the parenting instead.
