이강 uses the word 추격전 (choo-gyuk-jeon), a term straight out of action movies meaning a 'pursuit/chase battle.' Dropping a cinematic word like this is a common way Korean speakers add self-deprecating drama to an awkward real-life moment — he's narrating his own embarrassing scramble as if it were a thriller.
요양원 (yoyang-won) is a long-term residential care facility, distinct from a regular hospital. Placing an elderly or ill parent in one carries real social stigma in Korea, where Confucian values traditionally make adult children — especially sons — responsible for personally caring for aging parents at home. 이강 mentioning it so matter-of-factly signals he has already come to terms with carrying that judgment.
Korea has one of the world's highest rates of alcohol consumption per capita, and alcohol-related family problems are a quietly common but rarely spoken-about issue. A parent's 알코올 중독 (alcohol addiction) is the kind of personal detail a Korean student would only share in a written assignment — bringing it up face-to-face is far more vulnerable than it might look on screen.
언니 (eonni) is the word a woman uses for her older sister — it carries deep warmth and is also used between close female friends. Hearing someone refer to a deceased older sister as just 언니, with no name, is a quiet but powerful signal of grief in Korean speech; the word itself holds the entire relationship.
법적인 대응 (legal action/response) is a very loaded phrase in Korea. Defamation law there is unusually broad — you can be sued or even criminally charged for spreading true but damaging information if it harms someone's reputation. When a powerful person says 'I'll take legal action,' it is a genuine and effective threat, not just bluster, which is why the housekeeper has real reason to back down.
좆밥 is a crude compound insult — 좆 is a vulgar word for male genitalia, and 밥 means rice/food, together meaning something like 'worthless piece of trash.' It sits at the harshest end of Korean profanity. The fact that 민희 uses it so freely about the man she's been blackmailing tells us exactly how much contempt she actually has for him beneath the polite front.
출판 기념회 (chulpan ginyeomhoe) is a book publication celebration party, a well-established social ritual in Korean intellectual and literary circles. They are semi-formal events where academics, journalists, editors and well-connected friends all mingle — the kind of gathering where personal reputations are on full display, making it exactly the wrong place to have a confrontation about plagiarism.
Saying something would be a 실례 (silye, disrespect) to the 고인 (goin, the deceased) reflects a deeply held Korean belief that the dead retain social standing and deserve continued consideration. Rushing or making a fuss around funeral arrangements isn't just tactless — it is seen as a moral failing that reflects on the whole family.
Koreans sing 생일 축하합니다 (saengil chukha hamnida) to the same melody as 'Happy Birthday to You.' The lyrics literally mean 'Congratulations on your birthday' — the word 생일 (birthday) + 축하합니다 (congratulations/celebration). Cutting to a warm family birthday party at this exact moment of the episode is a deliberate tonal contrast — the drama is placing ordinary domestic happiness right next to what the audience now knows is lurking underneath it.
Korean hospital staff in emergencies mix Korean and English medical loan-words fluidly: 어레스트 (arrest — cardiac arrest), CPR, 컴프레션 (compression), 에피 (epi — epinephrine/adrenaline), 인튜베이션 (intubation), 펄스 (pulse). This isn't laziness — these terms entered Korean medical education directly from English-language textbooks and are the standard clinical vocabulary, just as they are in many countries.
The professor is proposing that 이강 become a false witness — essentially committing 위증 (wijeung, perjury) or filing a false report, both criminal offences in Korea. The drama frames this as a moral turning point: throughout the episode 이강 has been the passive note-taker, and now the story he has been writing is being asked to become something he has to live inside.
