Minhyuk says he can finally 'stretch out his legs and sleep' (발 뻗고 자다). This common expression means sleeping without worry or guilt — like you no longer have to curl up in anxiety. It's the Korean equivalent of 'sleeping soundly with a clear conscience,' and Koreans use it constantly when a long stressor has finally been resolved.
Baek Tak proudly declares that what the crime boss gang did is '노블레스 오블리주' — the idea that the privileged have a duty to serve society. The term is used seriously in Korean civic discourse but here it's played for laughs: a gangster genuinely believes that accidentally helping catch a serial killer counts as their aristocratic social responsibility.
Bong-soon's mom declares she is a '팩트 폭격 (fact bombing), 안구 테러 (eye terror)' kind of person. Both are popular Korean internet terms: '팩트 폭격' means overwhelming someone with blunt, undeniable truths, and '안구 테러' literally means 'assaulting the eyes' — used when something is so shocking or offensive to look at it feels like an attack. She's saying she wins arguments with evidence and brutal honesty, not fists.
Minhyuk receives a pour of 소주 (soju), Korea's signature distilled spirit, from Bong-soon's father at an outdoor campfire setting. In Korean culture it's an important gesture of acceptance when an elder pours for a younger person — receiving the glass with two hands and drinking immediately signals respect. The whole scene is essentially an informal marriage-permission negotiation conducted through shared cups.
Bong-ki uses the word 인연 (inyeon), which goes deeper than the English word 'fate.' In Korean thought, 인연 describes the invisible thread linking people across time — it's rooted in Buddhist ideas about karmic bonds. Koreans use it to explain why certain people keep crossing paths, and it carries a weight that 'destiny' in English doesn't quite capture.
The judge sentences the killer to 무기징역 (life imprisonment). South Korea still has the death penalty on its books, but executions have not been carried out since 1997, making Korea a de facto abolitionist state. Life imprisonment is therefore the most severe sentence a court realistically hands down for the most heinous crimes, which is why the verdict feels final and satisfying here.
Bong-soon receives a '용감한 시민상' (Brave Citizen Award) from the police chief. Korean police departments and local governments regularly present these certificates to civilians who assist in catching criminals or preventing harm. Because Bong-soon's supernatural involvement must be kept secret, the award goes to Minhyuk instead — a running gag about him having to publicly take credit for her heroics.
Bong-soon's parents mention having Bong-soon and Minhyuk's 궁합 (gunghap) checked. Gunghap is a traditional compatibility reading based on both people's birth dates and the Chinese zodiac — couples or their parents consult a fortune teller (사주쟁이) before marriage to see if the pair's energies harmonise. Getting a great result is a meaningful seal of approval in many Korean families, even today.
Guk-doo tells Bong-soon she was always his 코스모스 (cosmos flower). The cosmos is one of Korea's most emotionally loaded autumn wildflowers, famously lining country roadsides and school paths. In Korean poetry and song it symbolises something delicate, unassuming, and quietly beautiful — the opposite of showy. His confession that he called her frail and small, when really he meant lovely and irreplaceable, reframes years of their friendship in one word.
As petals fall, Minhyuk quietly says '초속 5센티미터' — 5 centimetres per second, the speed at which cherry blossoms drift to the ground. This is also the title of a beloved 2007 Japanese animated film that was enormously popular among Korean young adults, about longing and the distance between people. Dropping the phrase in this moment layers a very specific romantic nostalgia onto the scene for any viewer who knows the film.
Bong-soon uses her signature mangled French: '팜므 옴탈.' She means 'femme fatale' (팜므 파탈), but consistently garbles the second word. It has been her quirky self-description all series — she believes she is a dangerously alluring woman, and the mispronunciation is the show's gentle joke that she is endearingly unaware of how the word actually sounds.
At the wedding, Bong-soon's mom prays specifically for a grandson, asking the Buddha to help 'our Bong-soon give birth to a son.' Korea's traditional preference for male heirs (남아 선호) has faded dramatically among younger generations, but older parents sometimes still voice it — which is why the show plays it for comedy: the prayer is sincere, but the audience knows it's a generational quirk Bong-soon herself would roll her eyes at.
When Minhyuk learns the twins are both girls, someone teases him with '딸딸이 아빠' — a dad whose kids are all daughters. In Korean culture this was historically said with mild pity because of the old preference for sons, but today it is increasingly said with affection or pride. The scene flips the phrase on its head: Minhyuk is absolutely over the moon, and the old stigma dissolves into pure joy.
