Korean expression of relief
0:45
민혁 says he can finally 'stretch his legs and sleep' (발 뻗고 자다). In Korean this idiom means resting easy with a clear conscience — the opposite of lying awake worrying. After the serial kidnapper is caught, it's the perfect phrase for exhaling a long-held breath.

노블레스 오블리주 (Noblesse Oblige) in Korean culture
2:28
백탁 declares that helping catch the villain is their 'noblesse oblige' — a French phrase Koreans use to mean that people of wealth or status have a duty to act for the public good. The joke is that his crew are gangsters claiming a high-minded social duty, which the show plays entirely for comedy.
#
Korean poetic expression for loneliness
5:38
공 비서 says a crow is crying inside his chest (가슴속에 까마귀가 울고 있다). Crows in Korean tradition are associated with bad omens and melancholy, so the image captures a hollow, aching loneliness. 오돌뼈's deadpan appreciation — 'how poetic' — is the punchline.

쑥갓 (Crown daisy) in Korean cooking
8:14
칠구 corrects 민혁 when he mistakes 쑥갓 for 쑥 (mugwort). 쑥갓 is crown daisy, a leafy herb with a distinctive bitter fragrance used in soups, hotpots, and stir-fries. Confusing it with the similar-sounding 쑥 is a classic city-boy mistake — 쑥 is a completely different plant used in rice cakes and teas.

Asking a father's permission to marry
9:38
민혁 formally tells 봉순's father he wants to marry her and asks for his blessing (허락해 주세요). Seeking parental approval before proposing is still a deeply respected custom in Korea. Doing it face-to-face, sitting humbly, carries far more weight than simply announcing a decision after the fact.
#
무기징역 (Life imprisonment) in the Korean legal system
21:50
The judge sentences the villain to 무기징역 — literally 'unlimited-term imprisonment,' i.e. life in prison. Korea does not have the death penalty in practice (executions have been suspended since 1997), so a life sentence is effectively the harshest punishment a court can hand down for murder and serial abduction.
#
용감한 시민상 (Brave Citizen Award)
22:51
봉순 receives a 용감한 시민상, a real category of civic award that Korean police and local governments give to ordinary people who help prevent crime or rescue others. Because 봉순's superhuman role had to be kept secret, 민혁 took the public credit — making the ceremony especially awkward for him.
#
코스모스 (Cosmos flowers) as a symbol of feminine fragility
28:18
국두 once said he liked 코스모스-type girls — delicate, swaying wildly in the wind, in need of protection. Cosmos flowers bloom along Korean roadsides every autumn and are a classic poetic symbol of gentle, unassuming beauty. 봉순 spent years hiding her strength because she feared she didn't match that image.
#
초속 5cm (5 Centimetres Per Second) — cherry blossom reference
40:32
'초속 5cm' is the speed at which cherry blossom petals (벚꽃) fall — a fact made famous by the 2007 Japanese animated film of the same name, well known among Korean young adults. 민혁 uses it romantically to ask how fast his own feelings were moving toward 봉순.
#
팜므 파탈 — Korean mispronunciation joke
46:42
봉순 says she's a '팜므 옴탈' instead of the correct French loanword '팜므 파탈' (femme fatale). She has been mispronouncing it all series, replacing '파탈' (fatale) with the nonsense syllables '옴탈.' 민혁 finds it endearing every time and plays along rather than correcting her.
#
사내 연애 (Office romance) attitudes in Korea
54:04
오돌뼈 bluntly says she doesn't do 사내 연애 — dating within the same company. Office romance is a hot-button topic in Korean workplaces: company policies often discourage or require disclosure of relationships between colleagues, and many Koreans worry it feels too close, like dating a relative (근친).
#
아들 선호 사상 (Son preference) treated as comedy
64:11
진이 prays to Buddha specifically for a grandson (아들), framing it as the only way for her son-in-law 민혁 to 'sleep with his legs stretched out' — a callback to the episode's opening joke. Korea's historical preference for male heirs is now widely acknowledged as an old-fashioned attitude, so the drama plays 진이's desperate prayer for laughs rather than endorsing it.
#
딸딸이 아빠 (Father of daughters only)
65:06
민혁 discovers 봉순 delivered twin girls, making him a '딸딸이 아빠' — a colloquial term for a dad with only daughters. Older generations sometimes treated this as unlucky, but younger Koreans have largely reclaimed the phrase affectionately. 민혁 is overwhelmed with joy, not disappointment, which is the show's gentle nudge at changing attitudes.
