Major Korean newspapers and broadcasters assign dedicated reporters to cover the prosecutors' office full-time — a beat called 검찰청 출입 (geomchalcheong chulip). These reporters work so closely with prosecutors that they often develop personal relationships, which is why Seon-u casually mentions knowing a journalist through that connection. It is one of the most competitive and politically sensitive beats in Korean journalism.
포카라 (Pokara) is the gateway city to the Annapurna mountain range in Nepal and a well-known destination for Korean trekkers and mountaineering expeditions. Korean news outlets sometimes send journalists there to cover high-profile climbing missions. Seon-u uses this real geographical detail to make his cover story about a different reporter named Ju Min-yeong sound credible.
출생의 비밀 (chulssaeng-ui bimil), literally "birth secret," is one of K-drama's most beloved — and mocked — plot devices: two people fall in love, then discover they are actually related. Seon-u uses it here as dark, self-aware humour, essentially describing his own impossible situation through the lens of a TV cliché that every Korean viewer would recognise instantly.
The phrase 유지를 받들다 (yuji-reul batdeulda) means to carry on the will or dying wishes of someone who has passed. Jin-cheol pledging to honour Jeong-u's late father's 유지 is a formal, almost solemn expression in Korean culture, implying a debt of loyalty between families that goes beyond ordinary friendship — and in a business context, it often comes with strings attached.
"시작은 미약하나 그 끝은 창대할지니" is a Korean rendering of Job 8:7, meaning "though your beginning was humble, your end will be great." It is quoted so frequently in Korean business and motivational contexts that most Koreans recognise it immediately, even without religious intent. Jin-cheol reciting it here, alone in front of his new nameplate, underlines his ruthless ambition dressed up in lofty language.
하한가 (hahanga) refers to the maximum daily price decline allowed on the Korean Stock Exchange — currently 30 % below the previous day's closing price. When the news anchor says Myeongse Hospital's related stocks all hit 하한가 at once, it signals a complete collapse of investor confidence. Korean viewers understand this shorthand instantly as financial catastrophe.
Disclosing that someone is taking 우울증 약 (uuljeung yak — antidepressants) is still a significant admission in Korean society, where mental health treatment carries real stigma. Yu-jin mentions it specifically to make Seon-u understand how serious his brother's suffering is — the implication being that a proud Korean man admitting to needing medication is an extraordinary sign of how low he has fallen.
Seon-u playfully calls Ju-hui's lack of an umbrella a 꼼수 (kkomsu) — a sneaky little scheme. Sharing an umbrella, called 우산 쉐어링 in casual speech, is a classic Korean dating move: the close quarters force physical proximity and create an intimate moment. It is referenced constantly in K-dramas and rom-com webtoons, which is why Seon-u names it so confidently.
Min-yeong says she actually called the Pokara hotel and asked them to look up guest records — a detail that shows how desperate she is to verify her recovered memories. In South Korea, hotel guest registers (투숙객 기록) are protected personal data, so a member of the public asking a foreign hotel to confirm whether two specific people stayed there is a measure of last resort, and its failure only deepens her anguish.
Min-yeong realises the handwritten message she left inside a vinyl record album was her own private 혼인 서약 (honin seoyak) — wedding vow. In Korean weddings, vows are typically read aloud at a ceremony in front of witnesses; writing one secretly in a record sleeve, with no ceremony and no witnesses, captures the heartbreak of a bond that existed in one timeline but has left no official trace in another.
삼촌 (samchon) literally means paternal uncle. Throughout the drama Seon-u has used this word to keep Min-yeong at arm's length, reminding her of the familial label that makes any romantic feeling socially and legally unacceptable. His admission here that it is the word he most hates to hear is a quiet but enormous emotional reversal — in Korean, the label of a family role carries far more relational weight than it does in English.
Seon-u's declaration that Min-yeong "already married" him — referring to what happened during a past-timeline visit via the incense stick — draws on a distinctly Korean cultural gravity around marriage. In Korean law and tradition, a marriage ceremony and mutual consent create a binding bond even before civil registration. Framing the time-travel event in this language makes his claim feel categorical rather than fantastical to a Korean ear.
