Korean company 워크숍 (workshop retreats) often assign sleeping spots by lottery or rank. A 비박텐트 (bivouac tent) is a bare-bones outdoor tent with no amenities, while a 캠핑카 (camper van) is the coveted prize — it has a bed, heating, and privacy. Landing the camper van in this game is a big deal both for comfort and for what it implies about spending the night with someone.
Jiwon's words here echo the show's core premise: she has somehow been sent back in time and is reliving her past. For Korean audiences familiar with the 회귀 (hoegwi, time-regression) genre of webtoons and dramas, her fear of repeating the same mistakes is a classic character beat — the whole point of getting a second life is to make different choices.
Sumin's blunt offer — asking Minhwan to spend the night with her — is a direct sexual proposition, and the drama plays it as such. The campsite setting, the alcohol, and the isolated camper van all frame it as a calculated move. Korean dramas rarely have characters this explicit about physical intent, which signals to the audience just how far Sumin is willing to go.
고라니 literally means 'water deer,' a wild animal common in Korean countryside. At office retreats, the joke is that the remote outdoor setting makes colleagues behave like 발정난 고라니 — deer in rut — a crude way of saying people hook up or act recklessly at company workshops. It's a well-worn Korean office comedy trope.
Jiwon notes she has known Sumin for 26 years and Minhwan for 17 years — friendships that began in childhood and teen years respectively. In Korean culture these are 소꿉친구 (childhood friends) and 학창 시절 친구 (school-era friends), bonds considered almost as close as family, which makes the betrayal by both of them particularly devastating.
Minhwan's friend recounts the previous night's events using the kind of purple, literary phrasing found in Korean romance novels — a comedic contrast with what is essentially gossip. Describing a hook-up with flowery prose is a running joke in Korean comedy, poking fun at men who romanticize their own behaviour.
In Korean law (식품알레르기표시제), food businesses must clearly label the 22 major allergens, including tree nuts like 잣 (pine nuts / pine seeds). Failing to post an 알러지 표지판 (allergy notice board) at a tasting event is a genuine legal and corporate liability issue, not just bad manners — which is why the team panics and moves to pay the family off quickly.
Korean stocks can only fall a maximum of 30% in a single day — this lower limit is called 하한가 (hahannga, lower circuit limit). When sell orders pile up at that floor price and no one is buying, the stock can be put into 관리 종목 (watchlist status) and eventually hit with 거래 정지 (trading suspension). At that point your shares can become completely illiquid — you literally cannot sell them for any price.
사채 (saechae) refers to high-interest loans from unofficial private lenders — essentially loan sharks operating outside the regulated banking system. Borrowing from them is considered a last resort and a sign of financial desperation because the interest rates can be extreme and collection methods aggressive. Admitting to 사채 debt is a significant face-losing confession in Korean society.
"한강 수온 체크" (checking the Han River water temperature) is a dark internet-era euphemism for suicidal ideation. The Han River, which runs through central Seoul, has unfortunately been associated with suicide, and this phrase — used here by Minhwan in self-pity — carries that meaning for Korean viewers even when spoken half-jokingly.
South Korea has mandatory military service for men, typically around 18–21 months. 의병제대 (uibyeong jedae) is an early discharge granted when a soldier is injured or develops a medical condition that prevents continued service. It carries no shame, but mentioning it signals that something serious happened to his body while in the military.
Proposing on a partner's birthday is a popular choice in Korea because it bundles romantic effort into a day that already feels special. It also puts pressure on the recipient — refusing a proposal on your own birthday feels doubly awkward. Korean variety shows and dramas often portray birthday proposals as either very sweet or, as here, a calculated emotional manipulation tactic.
상견례 is the formal first meeting between a couple's two families before a wedding, usually at a restaurant. It involves careful attention to seating, speech formality, and gift-giving, and effectively signals that an engagement is official. It is a much bigger social ritual than a Western-style 'meet the parents' dinner — both sides are evaluating the other family's status and character.
