써니 mentions 아홉수 (ahopsu), the belief that years ending in 9 — age 9, 19, 29, 39 — are unlucky. Many Koreans avoid big decisions or risky moves in these years, so the idea of travelling abroad at 29 feels especially reckless to her.
덕화 introduces himself as a 재벌 3세 (jaebeol samse), meaning his grandfather founded a major conglomerate and he is the third generation to inherit it. In Korea, chaebol families like Samsung or Hyundai are household names, and '3세' signals someone born into immense, almost untouchable wealth.
The Grim Reaper gives the name '김우빈' — which is the real name of a hugely popular Korean actor known for his tall, striking looks. Using a celebrity name as a throwaway alias is a running gag; 써니's friend immediately reads it as a joke, assuming he must be a waiter.
써니calls 덕화 her 건물주님 (geonmulju-nim) — literally 'esteemed building owner.' In Korean cities, owning the building your shop is in means your landlord has enormous power over your livelihood. Calling someone 주님 (Lord/Master) here is half-joking but reflects genuine respect.
Korea's official government lottery, 로또 6/45, draws every Saturday night and is a national ritual. Players pick six numbers from 1 to 45; matching all six wins the jackpot. When no one wins, the prize rolls over to the next week — exactly what 김신 explains is about to happen.
Korean law prohibits anyone under 19 from purchasing lottery tickets. 은탁 is still 18 (a high-school student preparing for the 수능), so the shop clerk refuses her outright — the goblin's tip is useless to her until she turns 20.
The Grim Reaper tells departing souls that the afterlife is a 유턴 (U-turn) — you exit through the same door you entered. This plays on the Korean cultural idea of reincarnation or the soul returning to where it came from, wrapped in an everyday traffic metaphor.
도깨비 are figures from Korean folklore: supernatural beings born from objects soaked in human blood or spirit, capable of tremendous power and mischief. Unlike Western goblins they are not inherently evil — they can be generous protectors. The show reimagines 김신 as an immortal dokkaebi created through a tragic death in battle.
The Grim Reaper explains that 9 is both a divine number and the last step before the 'complete' number 10, making it the most precarious age. This ties back to 아홉수: folklore treats 9-years (9, 19, 29…) as thresholds where fate is most unstable and spiritual intervention most likely.
메밀 (buckwheat) fields blooming with small white flowers are a beloved image in Korean literature and rural life, immortalised in the classic short story 『메밀꽃 필 무렵』 (When Buckwheat Flowers Bloom) by 이효석. Choosing this setting gives the scene a quietly literary, nostalgic weight that Korean viewers feel immediately.
Korean contracts label the more powerful party 갑 (gap, Party A) and the less powerful party 을 (eul, Party B). 갑질 — abusing that power — is a serious social issue. 은탁 cheekily assigns herself the role of 을 and 김신 the role of 갑, then uses the formal contract language to lock him into a promise to come back.
김신's farewell speech — 'because the day was nice, because it wasn't, because it was just right, every day was good' — echoes a well-known line style in Korean lyric poetry where contradictory reasons collapse into a single feeling of gratitude. The repetition is a deliberate poetic device, not a mistake.
