만수무강하십시오 is a deeply formal Sino-Korean phrase wishing someone ten-thousand years of health and long life. It's the kind of elevated blessing you'd shout at a superior's birthday party — half sincere, half playfully over-the-top — which is exactly why the whole room bursts out laughing here.
The office party has turned into a singing session, a staple of Korean 회식 (hoesik) — the compulsory after-work gathering. Singing together, especially boisterous duets by the newest employees, is expected to show team spirit. Refusing to perform can actually mark you as a poor fit for the group.
The boss orders Seon-u to escort the injured new hire to the hospital purely because he arrived late and literally knocked her over. In Korea's hierarchical office culture, the senior person present is expected to take personal responsibility for a junior colleague's welfare — even when the situation is awkward or inconvenient.
개또라이 stitches 개 (dog, used as a crude intensifier) onto 또라이 (a nutcase or total weirdo). The compound reads as something like 'a complete raving lunatic.' It's rude but not the heaviest profanity in Korean — more exasperated than vicious — which is why Seon-u says it while half-laughing.
In Korea, items seized as 증거품 (jeunggeopum, physical evidence) during a criminal or accident investigation are held by police and only returned to their owner once the case is officially closed. Receiving a package back from the station is a quiet signal that the authorities consider the matter finished — here the hospital fire.
막장 originally described a dead-end mine shaft — the most desperate, dangerous spot a miner could reach. Applied to drama or real life it means a situation so scandalous and convoluted it's practically unwatchable: secret identities, hidden parentage, forbidden love all at once. Seon-u uses it about his own life, which is both bitter and darkly funny.
In Korea, a marriage becomes legally binding the moment the 혼인신고 (marriage registration) is filed at the local government office — not at the wedding ceremony. Min-yeong is pointing out that if she is already registered as Seon-u's wife, a second registration with anyone else would be bigamy under Korean law, making the upcoming wedding literally impossible.
패륜 (paeryun) means a violation of the most fundamental Confucian family bonds — the kind of act society considers almost unforgivable, like a child harming a parent or romantic involvement between close relatives. Seon-u uses it to name what their relationship looks like from the outside, before immediately explaining why the label doesn't actually fit.
턱을 쏘다 literally means 'to shoot a treat' — Korean slang for paying the entire bill for a group. A senior who promises to 'buy the round' every time a stock rises is taking on a running tab of obligation; the junior's breezy confidence that it will keep climbing makes the moment both funny and a little cheeky.
Jung-u reveals that for twenty years he has wanted to die over what he did, but held back because of his family. This is a direct disclosure of long-term suicidal thoughts rooted in guilt and shame — a serious moment the drama treats with weight rather than melodrama. If this resonates personally, the Korea Suicide Prevention Hotline is available 24 hours at 1393.
이민 수속 refers to the full administrative process of formally emigrating from Korea: medical checks, asset declarations, and government clearance. In the 1990s this was a lengthy and visible procedure, which is why Jung-u says he was tempted to turn himself in every time he walked past a police station — the weight of the secret was constant during that paper trail.
A 레코드 숍 (record shop) selling LP and cassette albums was a common small business in 1990s Korea, often run by music-loving owners and serving as informal neighbourhood gathering spots. The name 'Floor Records' and the shop's atmosphere place this flashback squarely in that era, before digital music made such stores disappear.
청부업자 means someone hired to carry out a job on another person's behalf — here a fixer or enforcer working for Chairman Choi. The alarm in Jung-u's voice comes from realising that Choi has already identified Seon-u's face, making him a loose end that Choi's청부업자 has been sent to silence.
