뽀삐 (Ppopi) is a classic, old-fashioned Korean dog name — the rough equivalent of 'Fluffy' or 'Spot' in English. Older Koreans especially associate it with the beloved family pets of their childhood. The little girl's ghost apparently used this name, and the retired soldier adopting the stray dog with the same name is meant to feel like a small miracle of connection.
Under South Korean law, any licensed medical doctor (의사) — including a dentist (치과 의사) — can legally pronounce death. It is not limited to general practitioners or emergency physicians. The character invoking this obscure-but-real legal fact is a sharp, darkly comic moment that shows her training and composure in an unbearable situation.
공대생 (gongdaesaeng) literally means 'engineering college student.' In Korean internet culture it's a lighthearted stereotype for someone who thinks in rigid, hyper-logical steps and misses the emotional or moral big picture. Calling an angel's argument '공대생 같은 논리' is a deadpan insult — you're saying a divine being sounds like a freshman who only passed math.
족보 (jokbo) is a family genealogy register — a very serious document in Confucian Korean culture that records ancestral lineage. Attaching 개 (dog/bastard) in front of it turns it into a cutting insult meaning something like 'nonsense hierarchy' or 'fake bloodline.' The character is mocking the villain's elaborate supernatural family-tree power structure as worthless rubbish.
In Korean shamanistic belief (무속, musok), animals — especially birds — dying without apparent cause is a serious omen that the spirit world is disturbing the natural order. Using dead birds on the road as a coded distress message works here because any Korean viewer steeped in that cultural layer would immediately feel the dread it's meant to signal.
염 (yeom) is the traditional Korean practice of carefully washing and wrapping the deceased's body before the funeral, usually performed by specialists or, in older communities, by trusted elders or family. When the women say 'the yeom is ours to do,' they are claiming an act of deep love and respect — keeping the ritual within the community rather than handing it to strangers.
The character uses a simple arithmetic joke: negative one multiplied by negative one equals positive one. It's a nerdy, emotionally guarded way of saying two broken or 'bad' people can make something whole together. This kind of math-as-emotional-logic is a recognizable K-drama trope for characters who struggle to express vulnerability directly.
In Korea, funeral costs (장례 비용) are traditionally handled by the family as a collective duty, and it's common for relatives or even community members to contribute 부조금 (bujogeum) — condolence money in white envelopes. A parent quietly setting aside money specifically earmarked for their own funeral so as not to burden their child is seen as an act of deep, self-sacrificing love.
