Ga-yeong asks for her grandmother to become the same age as her — in Korean culture, sharing an age (동갑, dong-gap) is a meaningful social bond that erases formal hierarchy between two people. By wishing for this rather than simple 'youth,' she's imagining a relationship of equals, not just a physical transformation.
The grandmother agrees to go to Hawaii mainly because the tickets are non-refundable — wasting money (돈 아깝다, don akkap-da) is a powerful motivator in a generation that lived through postwar scarcity. Buying the tickets first and presenting them as a fait accompli is a well-known trick adult children use to get reluctant Korean elders to accept gifts.
The women at the senior gathering are speaking in 경상도 사투리 (Gyeongsang-do saturi), the dialect of the southeastern region (Busan, Daegu, and surrounding areas). It has a strong rising-and-falling pitch accent and vocabulary that sounds almost like a different language to Seoul ears — which is exactly why Ga-yeong later bans Pan-geum from speaking it in public.
제사 (jesa) is a Confucian memorial ceremony held on the anniversary of a family member's death, usually late at night. The eldest son traditionally hosts it and prepares a full table of food for the ancestor's spirit. The phone call here shows family tension over who is responsible — missing your own family's jesa is considered a serious breach of filial duty.
새참 (saecham) is the traditional mid-morning or mid-afternoon snack break given to farm laborers working in the fields. The landowner brings out food and sometimes makgeolli (막걸리, unfiltered rice wine) as part of the unspoken contract of day labor. It's a small but important moment of communal rest — refusing it would be rude.
The flashback references a prestigious science university and a full scholarship (총장 장학생, president's scholarship) — the highest honor a student can receive. Refusing it, as the character apparently did, would be almost unthinkable to most Korean families and signals extreme financial confidence or deliberate unconventionality.
The village chief mentions a '밴드 (band)' — this is Naver Band, a Korean social app widely used by neighborhood associations, apartment complexes, and rural village committees to share notices, emergency alerts, and community gossip. Being on the village Band is essentially the Korean equivalent of being on the neighborhood group chat; not joining signals you're not a real resident.
포장 (pojang) literally means 'wrapping' and is the standard word for getting restaurant food to take away. Unlike Western takeout culture, it's completely normal in Korea to eat at a restaurant and then ask for a separate portion to take home — restaurants routinely pack banchan (side dishes) alongside the main. The grandmother casually ordering 'a big one to go' mid-conversation is perfectly natural behavior.
당근 (Daangn, formerly 당근마켓 Daanggeun Market) is Korea's dominant hyperlocal secondhand trading app — think Craigslist but neighborhood-locked and much cleaner. Ga-yeong mentioning she bought a wrench set there is perfectly ordinary; Koreans buy and sell everything from tools to furniture to baby clothes on Daangn, usually meeting in person nearby.
In Islamic tradition that the show borrows from, Iblis (이블리스) is the being who refused to bow to Adam and became the embodiment of temptation, while angels (like Izrael/이즈라엘, the angel of death) carry out divine will. The drama uses this theology literally: Iblis wants humans to fall through their own wishes, while Izrael seems to be playing a counterbalancing role by offering Ga-yeong information.
