A 도깨비 is a creature from Korean folklore — a spirit born from objects soaked in human blood, often depicted wielding a club and granting wishes. This drama reimagines him as an immortal guardian with a sword fused into his chest. The word is sometimes loosely translated as 'goblin,' but Korean dokkaebi are mischievous helpers, not the malicious goblins of Western fairy tales.
Korean rental housing often runs on a system called 전세 (jeonse) or 월세 (wolse), where tenants pay a large lump-sum deposit called a 보증금 (bojeugeumm) instead of, or on top of, monthly rent. When Eun-tak's aunt empties the deposit and leaves, she has taken the single biggest asset tied to their home — effectively wiping out Eun-tak's housing in one move.
재벌 (jaebeol) refers to the giant family-owned conglomerates that dominate the Korean economy — think Samsung or Hyundai. A '재벌 3세' is a third-generation heir, which carries enormous social weight in Korea. Duk-hwa casually dropping this label is both a boast and a joke, since his grandfather still controls his credit card.
Arriving at school in a luxury sedan is a very deliberate social performance in Korea. Korean high schools are status-conscious environments, and pulling up in a black executive car draws instant attention from classmates. Duk-hwa openly admits he wants all eyes on them — this kind of arrival is a known flex among wealthy Korean teens.
The police officer mentions that the gold bar should be held by the New York Federal Reserve — a real arrangement where some of Korea's official gold reserves are stored abroad for liquidity. Korean gold bars stamped by the 한국은행 (Bank of Korea) are genuine government assets, so the family's casual handling of one makes the situation absurdly criminal from a legal standpoint.
저승사자 (Jeosung saja) is Korea's version of the Grim Reaper — a messenger from the underworld who escorts the dead to the afterlife. In this scene he's watching a 아침 드라마 (morning drama), a real Korean TV genre known for outrageous birth-secret plot twists, which is exactly the kind of twist playing out on screen. His genuine shock at the reveal is a wink at how melodramatic these shows can get.
In Korean folk belief, a 도깨비 can bestow sudden fortune or protection on people it favors. The drama builds on this: Kim Shin has quietly intervened in ordinary lives for centuries, handing out 'sandwiches' — small acts of help — to countless people. The idea that most humans cling to one miracle rather than building their own lives is the goblin's quiet frustration with humanity.
첫눈 (cheongnun), the season's first snowfall, is deeply romantic in Korean culture. There's a widespread belief — and many pop songs about it — that if you are with someone you love when the first snow falls, your wish will come true. Making a date for the first snow is one of the most classic moves in Korean romance, and both characters know exactly what it means.
'아끼다 똥 됐어' is a blunt Korean proverb that means roughly 'you saved it so carefully that it rotted.' Koreans use it when someone hoarded or hesitated too long and the opportunity spoiled. Sunny is applying it to herself — she held back from pursuing something (or someone) and now feels she missed her chance.
In Korean folk belief, 귀신 (gwisin) are the spirits of people who died with unresolved grudges or unfinished business. This show uses them as a recurring element: because Eun-tak can see and talk to them, they become informal allies who help her in small ways. The dialect-speaking grandmother ghost is likely from the Gyeongsang region — her satoori (regional speech) makes her feel warm and comedic rather than scary.
Koreans affectionately call Canada 단풍국 (dangpungguk), literally 'Maple Leaf Country,' a nod to the Canadian flag. Eun-tak gave Kim Shin a maple leaf as a small gift in an earlier episode, so him teleporting her to Quebec — where autumn maples are everywhere — is his way of repaying a single leaf with an entire country of them.
Kim Shin calls himself a '당찬 도깨비' — a bold or plucky goblin. The word 당차다 (dangchada) describes someone who is spunky and self-possessed despite difficult circumstances. It's a slightly old-fashioned, affectionate compliment in Korean, and hearing a 939-year-old supernatural being use it about himself is intentionally funny and endearing.
Kim Shin reads aloud what turns out to be a poem he wrote for Eun-tak, comparing her gravitational pull to Newton's apple. Reciting or writing 시 (si, poetry) is a traditional way in Korean culture to express feelings too large or vulnerable for plain speech. That he frames his love as physics — mass, gravity, free fall — says everything about a man who has watched the world change for nearly a thousand years but still falls helplessly.
