Korean fried chicken (치킨) comes in three classic styles the delivery guy rattles off: 프라이드 (plain crispy), 양념 (spicy-sweet sauce), and 간장 (soy-garlic glaze). These aren't just flavors — they're almost separate dishes with devoted fans, and ordering for a group often means a heated debate about which to get.
The boys work at what appears to be a 치킨집 (fried chicken restaurant) that also handles delivery — one of the most common small-business types in Korea. Running the front (홀), handling deliveries, and doing favors for friends all at once is very much the reality of family-style restaurant work.
Eun-ho wears a fake ring to signal he's 'taken' and avoid unwanted attention — a quiet but widely recognized workaround in Korea, where being visibly single can invite unsolicited matchmaking pressure from bosses, relatives, and coworkers alike.
Ji-won is tracking her stock returns with the kind of close attention that became extremely common in Korea after the 2020 retail investment boom, when millions of ordinary Koreans — nicknamed 동학개미 (Donghak Ants) — poured savings into the market for the first time. Putting an entire paycheck in is treated here as an exciting but reckless move.
달콤새콤 (literally 'sweet-sour') is a popular Korean chewy candy, similar in vibe to Western sour gummies. It's an affordable, nostalgic snack — the kind of small thing a thoughtful friend would remember to stock up on. Min-hwan bringing it for Su-min while Ji-won forgot signals exactly who he's paying attention to.
Hee-yeon explains that her name 희연 is written with the Chinese characters 喜 (기쁠 희, 'joy') and 緣 (인연 연, 'connection/fate'). Koreans often choose names for their meaning, and it's common to ask how someone writes their name in hanja (한자) — the same spoken name can carry very different meanings depending on which characters are used.
Hee-yeon uses the acronym TPO — Time, Place, Occasion — a dressing philosophy popular in Korean fashion culture and women's magazines. It means your outfit should match the specific context you're in, and using the term signals style-consciousness. It's the Korean equivalent of 'dress for the room.'
Hee-yeon explains that 카피 (counterfeit luxury goods) in Korea are informally graded S, A, and B by quality — with S-grade fakes being nearly indistinguishable from the real thing. A 'no-effort grade' fake (무성의급) is so poor it doesn't even try to look genuine, which makes it a deliberate insult when given as a gift rather than a simple budget choice.
갤러리아 백화점 (Galleria Department Store) in Apgujeong is one of Korea's most prestigious luxury shopping destinations. Buying something there on 12-month 할부 (interest-free instalment plan) with a first paycheck is a recognisable milestone moment — a way of treating yourself to something meaningful while spreading the cost, which Korean credit cards make very easy to do.
The secretary quotes the Korean saying '안 하던 짓 하면 죽는다' — roughly 'if someone does something out of character, it means they're dying.' It's used half-jokingly to mean that a sudden, uncharacteristic behavior is a serious warning sign. Here it frames Ji-hyuk's sudden romantic stubbornness as alarming precisely because he never acts this way.
Eun-ho's declaration 'I liked you!' (니 좋아했다고!) is a formal 고백 (romantic confession). In Korean dating culture, clearly stating your feelings out loud — rather than hinting — is the expected step that opens the door to a relationship. The fact that he never did this in high school is treated as the crux of a years-long misunderstanding.
