Min-hyeok announces he is gay specifically so that Bong-soon's family and Guk-du won't object to her staying overnight at a single man's apartment. In Korean society, unmarried men and women sharing a home — even for work — is still considered highly improper, and a gay employer sidesteps that stigma entirely. The ruse is played for laughs but reflects a real social anxiety around 밤외박 (staying out overnight).
Guk-du proposes a 무박 2일 (mu-bak i-il), literally 'zero nights, two days' — slang for pulling an all-nighter and going straight into the next day without sleeping. It became a popular phrase from a long-running variety show of the same name where celebrities travelled and did challenges through the night. Using it here frames their drinking competition as a fun, spontaneous adventure.
The three characters move from billiards straight into a 술 시합 (sul si-hap), a drinking contest. Competitive drinking games are a staple of Korean social bonding — the loser of each round downs a glass of 소주 (soju) or beer. What looks chaotic is actually a structured ritual: refusing to drink when you lose is considered poor sportsmanship and a breach of group harmony.
Aghwi rattles off a rapid-fire list of rice meals — 국밥 (soup rice), 콩나물밥 (bean-sprout rice), 잡채밥 (glass-noodle rice), 볶음밥 (fried rice), 쌈밥 (lettuce-wrap rice), 맨밥 (plain rice) — to show he is taking the word '밥' (bap, rice/meal) very literally. In Korean, '밥 먹자' simply means 'let's eat,' and Baek-tak's irritation is that Aghwi is being absurdly pedantic about something obvious.
Drunk Guk-du murmurs that his carriage will turn into a pumpkin before midnight — a direct nod to the Cinderella fairy tale. Korean audiences know the story just as well as Western ones, but the joke lands harder here because Guk-du is the one playing the Cinderella role: he is the straight-laced, proper man who has accidentally ended up in an overnight situation that breaks all the rules he normally enforces.
A '지라시' (jirashi, from the Japanese chirashi) is an anonymous tip sheet that circulates among stock traders and journalists — essentially a rumour memo. In Korea, these unsigned documents can instantly move share prices because investors act on the gossip before it is verified. When a jirashi claims Min-hyeok is gay, Ainhoft's stock hits the 하한가 (hahanga), the daily lower circuit-breaker limit of 30%.
The aggressive driver mutters '병신년' — the Korean cyclical calendar name for 2016, the Year of the Red Monkey. In everyday speech, '병신' is also a crude insult meaning 'idiot' or 'cripple,' so the phrase has a double-edged, self-pitying tone. The drama is set in 2016–2017, and characters occasionally drop the year name as dark, self-deprecating humour about how rough things are.
Min-hyeok compares himself to the human heroine gazing at King Kong and saying 'Beautiful.' Korean rom-com heroes frequently reach for Hollywood films to describe feelings they find too embarrassing to state plainly — borrowing a fictional frame makes the emotion safer. His point is that Bong-soon's superhuman strength makes him feel small and protected, which is a gender-role reversal he finds both unsettling and thrilling.
The neighbours debate the exact title of the novel Guk-du's mother wrote — all versions involve '호르몬' (hormone) and a domestic space (room, attic, corner). When she arrives to explain it as a serious work about modern alienation, the gap between her pretentious literary framing and the neighbourhood gossip about it being a steamy bestseller is the joke. Self-published or independently distributed erotic fiction became a quiet commercial phenomenon in South Korea in the 2010s.
Team Leader Yuk name-drops '수사반장' (Susa Banjang), a legendary MBC crime drama that ran for 18 years and starred Choi Bool-am. It is the Korean equivalent of referencing a classic like 'Columbo' — a touchstone of analog detective intuition versus modern forensics. Yuk quoting it is his way of saying that reading human emotion matters more than CCTV footage, and it also signals his age to younger colleagues.
When Bong-soon's grandmother 순심 여사 (Sunsim Yeosa) single-handedly beats up the gangsters harassing women on the street, it confirms for the audience that the family's superhuman strength passes through the female line — something Bong-soon already hinted at earlier in the episode. Calling an older woman '여사' (yeosa, madam/lady) is a respectful title in Korean, often used for the wives of prominent men, but here it becomes quietly ironic given how formidable she is.
The pharmacist warns that taking sleeping pills (수면제, sumyeonje) long-term is harmful — a routine caution that also quietly flags something wrong with the male customer. In South Korea, benzodiazepine-type sleep aids require a prescription and pharmacists are trained to counsel patients about dependency. The scene plants a clue about the suspect's psychology through what looks like an ordinary pharmacy visit.
