뻥튀기 (ppeong-twigi) are airy puffed-rice crackers, and 강냉이 (gangnaeng-i) is a regional word for popcorn or puffed corn. In Korean pojangmacha-style drinking spots, light puffed snacks are often set out as a free nibble — the equivalent of bar nuts — while proper 안주 (anju, paid drinking food) is expected to be ordered separately. Chungjae is teasing Namsuk for filling up on freebies instead of ordering real food.
논산훈련소 (Nonsan Hullyeonso) is South Korea's main Army basic-training camp, where almost every able-bodied Korean man passes through mandatory military service. Doha's joke lands because the bark-and-drop drills Du-sik is putting Seong-hyeon through sound exactly like the infamous intensity of Nonsan boot camp — something every Korean man in the room has lived through.
The grandmothers are wrestling with the French names for the pastries Ji PD brought from Seoul: 에클레어 (éclair) and 카눌레 (canelé). Specialty French bakeries have boomed in Korean cities, but in a small seaside village these treats are still exotic enough that the elders can't quite pin down the words — a gentle gag about the gap between Seoul food trends and rural life.
Du-sik calls a round of 고스톱 (Go-Stop), Korea's most popular card game played with 화투 (hwatu, flower-pattern cards). 밤일낮장 is a scoring rule meaning night cards count as one point and day cards as a full card value. 끗수 (kkeut-su) means the score or point total — the player with the higher count wins the right to host Gamri.
Juri is saving up for 굿즈 (goods) from her favourite boy group DOS — official merchandise such as 포카 (photocards), grip-tok phone rings, and now embroidered T-shirts. Korean idol fandoms release new merch in multiple colourways so fans feel pressure to buy every version. Namsuk immediately recognises the struggle and secretly buys Juri one, the way a supportive 아줌마 (auntie figure) in the neighbourhood often steps in.
A 치기공사 (chi-gi-gong-sa) is a licensed dental technician who works in a lab making crowns and bridges — but they are legally barred from fitting anything in a patient's mouth. Namsuk has been directing patients to skip the dentist's finishing appointment and go straight to a technician friend who will attach the prosthetic cheaply. Hye-jin explains this is 무면허 의료 행위, unlicensed medical practice, and carries criminal penalties for both the technician and whoever acted as a broker.
오가피 (ogapi) is the bark of the Siberian or Korean acanthopanax shrub, used in Korean traditional medicine (한방, hanbang) as a tonic believed to ease joint and back pain. Du-sik has a stash of it at home — typical for a village handyman who knows folk remedies — and gives it to Hye-jin after hearing about her cervical disc problem, then she brews it into a bitter tea.
보이스 피싱 (voice phishing) is a massive social problem in Korea; scammers routinely pose as bank employees to collect cash in person. '김미영 팀장' (Team Leader Kim Mi-young) became a national meme after a 2019 documentary exposed how every caller seemed to use that exact name — so the moment the scammer blurts it out, both Hye-jin and the audience instantly recognise the con.
화정 reveals that Namsuk lost her daughter 아람 (Aram) and spent over a year in grief before channelling her pain into an annual donation to a children's hospital in the girl's name. In Korean culture it is common to make memorial donations (추모 기부) tied to a deceased person's name as a way of keeping their memory alive and 'doing good in their place.' This reframes all of Namsuk's loud, sometimes aggravating behaviour as the armour of a bereaved mother.
When meeting a girlfriend's parent for the first time, Korean convention calls for a very formal self-introduction: stating your full name, your connection, and using the respectful address 아버님 (abeoji-nim, 'Father' as an honorific). Du-sik jumps straight to calling himself Hye-jin's boyfriend, while Seong-hyeon uses the more measured title of 대학 선배 (university senior). The two introductions reveal exactly where each man stands — and neither answer surprises the father.
