In Korean folklore, a 도깨비 (dokkaebi) is a goblin-like supernatural being with great power. The idea that this particular dokkaebi needs a destined bride — 신부 (sinbu) — to pull the sword from his chest and end his immortality is the drama's own spin on that mythology. Finding her is both a longed-for release and, as this scene shows, a deeply complicated moment.
The TV programme rattles off 조울증 (bipolar disorder), 신경쇠약 (nervous breakdown / neurasthenia), and 불면증 (insomnia) — all real clinical terms, but the show plays them purely for laughs as a checklist of what Kim Shin is clearly displaying. Neurasthenia (신경쇠약) was a hugely popular diagnosis in 20th-century East Asia and still appears in everyday Korean speech as a catch-all for being emotionally frazzled.
Duk-hwa scrambles to remember the phrase 샤바샤바 (shaba-shaba), which is Korean slang borrowed from Japanese meaning to grease someone's palm or manipulate a situation through back-channel favours. He is connecting the dots that Eun-tak must be the girl his grandfather was secretly arranging things around — someone whose cooperation matters enough to pull strings for.
The police officer explains that the gold bar was originally produced by 한국은행 (the Bank of Korea, the country's central bank) and should currently be held by the Federal Reserve Bank of New York — a real arrangement where South Korea stores part of its gold reserves overseas. The joke is that a stray supernatural gold bar has ended up in a pawn shop because of a dokkaebi's casual generosity.
Kim Shin tells the departing soul that the afterlife is a 유턴 (U-turn) — you exit through the same door you entered. This is a wry, modern metaphor layered over a traditional Korean belief that the dead pass through a threshold between worlds. The drama regularly mixes ancient shamanistic ideas about the afterlife with deadpan contemporary language.
Kim Shin teleports them to Canada as a return gift for the maple leaf Eun-tak gave him. Quebec is famous throughout Korea as a dream autumn-foliage destination; the province's iconic 단풍 (fall colours) are widely featured in Korean travel media. Eun-tak saying she 'knows Quebec pretty well' is a teenage boast — she clearly does not — which is why he immediately redirects her.
Sunny works in what looks like a cosmetics or beauty shop, a setting that is ubiquitous in Korean commercial districts. A customer immediately asks about the eyeshadow Sunny is wearing and buys it on the spot — a very common occurrence in Korean beauty retail, where the staff's own look functions as a live advertisement. Sunny's friend teases her for being so naturally pretty that she sells products without trying.
The ghost who scolds Eun-tak's bully speaks in a thick 경상도 (Gyeongsang Province) dialect — 'gashina' for 'girl' and the characteristic '~카믄서', '~카다' endings. Korean dramas often give regional ghosts their home-province dialect to signal their era and origin, and here it also adds dark comedy: an elderly southern granny-ghost cheerfully approving of revenge.
Eun-tak expects Kim Shin to have a 도깨비방망이, the iconic magic club of Korean folklore that grants wishes when struck — the source of the chant '금 나와라, 뚝딱!' ('Gold, come out — thwack!'). Kim Shin corrects her: his weapon is a sword, not a club. He then demonstrates that the 'magic water' legend people know was actually him — the club story is the garbled folk memory.
Kim Shin's closing monologue — 'because the day was fine, because the day was not fine, because the day was just right, every day was good' — is one of the most quoted lines from this drama in Korean internet culture. It became a standalone phrase used to express unconditional contentment, shared widely on social media and printed on merchandise long after the show aired.
