'딸라' is a colloquial, slightly mocking Korean pronunciation of 'dollar.' Myeong-o is asking Sa-ra to exchange cash for him, using the slang word to keep things casual — but Sa-ra immediately turns it into a pun, snapping back that he should be worrying about his '딸' (daughter) instead of dollars.
Myeong-o demands one Bitcoin per 'page' of the embezzlement ledger — at the time the show is set, Bitcoin's price had been falling sharply (a '하락장,' or bear market), which is exactly why Jae-jun reacts with outrage rather than just fear. Paying in cryptocurrency also makes the transfer nearly untraceable, a common feature of Korean blackmail plots involving digital assets.
Yeon-jin works as a 기상캐스터 (gisang kaeseuteo), a weather forecaster who appears on screen during news broadcasts. In Korea these roles are highly visible and glamorous — casters are often celebrities in their own right — which makes Yeon-jin's public respectability a key part of her armor against Dong-eun's revenge.
Dong-eun admits she imagined herself as the unstoppable action hero from the Hollywood film 'Taken' (2008) when she first planned her revenge. The film is enormously popular in Korea and became shorthand for a one-person rampage of righteous vengeance — making it the perfect, slightly self-deprecating reference for how she pictured herself before reality set in.
Yeo-jeong has put up a small 'Welcome Home' sign for Dong-eun. For Korean viewers this lands with extra weight because 'home' (집) carries deep cultural meaning around safety, belonging, and family — things Dong-eun was systematically denied growing up. The English phrase on the sign is deliberately warm and slightly foreign-feeling, as if marking a fresh start outside her old world.
Dong-eun's first instinct when she sees a cozy lit-up house is to calculate the 난방비 (heating bill) and 전기세 (electricity bill). This is a deeply relatable reflex for Koreans who grew up in cramped or cold housing where utilities were a constant source of stress — and it's a quietly heartbreaking reveal about how Dong-eun's poverty shaped even her sense of beauty.
The retired detective confirms that So-hee's death was officially closed as suicide (자살로 종결). In Korea, once a case is formally concluded this way, reopening it requires significant new evidence and bureaucratic will — which is why the adults in Dong-eun's life were so confident that burying the truth would hold. The ease of that cover-up is part of what the drama is interrogating.
Hyeon-nam explains that she chose her daughter's name herself: '선' (善) means 'good/virtuous' and '아' (雅) means 'elegant/clear.' Naming children with hanja (Chinese characters) chosen for their meaning is a cherished Korean tradition, and parents often agonize over the choice — or, as Hyeon-nam jokes, worry that a poorly chosen name brings misfortune.
Yeo-jeong's mother, a surgeon, tells her son that his late father's 'blind goodwill and ethics' amounted to nothing more than empty glory. This is a pointed critique of a particular Korean ideal — the selfless, uncomplaining 사람 좋은 사람 (a truly good person) — suggesting that pure virtue without strategic action can fail the people it is meant to protect.
The autopsy report reveals So-hee was pregnant at the time of her death. In Korea, an unmarried teenage pregnancy in the early 2000s carried enormous social stigma, which would have added yet another layer of vulnerability and isolation for So-hee — and makes the cover-up of her death even more damning for everyone who knew and stayed silent.
Dong-eun quietly tells So-hee's mother that there were many moments she wanted to die, but that imagining bringing So-hee home kept her alive. She frames So-hee as the thing that literally 'put her to sleep' — a protective presence that broke the worst moments. This is the drama's most direct acknowledgment of Dong-eun's long-term psychological suffering from the bullying.
Yeon-jin tells Myeong-o she is in a '모임' (a gathering or social meeting) and can only meet at 11 p.m. Moim are a staple of Korean adult social life — alumni groups, neighborhood circles, work dinners — and citing one is a completely natural-sounding excuse that also signals she is maintaining her polished public life even as everything around her unravels.
