Eun-sae is quoting a popular Korean saying: '명품 몸매면 싸구려를 걸쳐도 빛난다' — 'If your body is designer-class, even cheap clothes shine on you.' The joke is that everyone repeats it, but she finds it backwards: building a 'designer body' is itself the hard part.
'쌤쌤' is a casual Korean slang term — a phonetic shortening of the English 'same same' — meaning 'we're even' or 'call it a draw.' Eun-sae is declaring that the unexpected kiss cancels out whatever awkward thing she did the night before, so they start with a clean slate.
In the early 2000s, Korean internet communities called '얼짱 카페 (eoljjang cafés)' — literally 'best-face cafés' — were online message boards on platforms like Daum Cafe where users voted on the most attractive photos. Being ranked number one was a genuine path to fame and sometimes a modelling or acting career.
율무차 (yulmu-cha) is a warm, slightly nutty Korean tea made from job barley (율무). It has been popular for centuries and is still sold at school festivals and traditional tea houses today. The young Gi-jun mentioning he loves it is a small character detail — it's considered an old-fashioned, homey drink for someone his age.
Soo-ji refuses the hospital coffee because she only drinks '당일 로스팅' — beans roasted the same day. This is a real preference in South Korea's very developed specialty-coffee culture, where third-wave cafés often print the roast date on the bag. Saying this in a hospital waiting room is a pointed display of refined taste.
Tae-ha jokingly calls the neighbourhood ahjumma trio '엿마을 SES.' SES was a massively popular K-pop girl group from the late 1990s — three members, huge local fame. Comparing three village women to them is a playful way of saying they are the undisputed queens of Yeot-village.
The investigator says '이 구찌가 큰 거는' — using 'Gucci' not as the fashion brand but as Korean street slang meaning 'this matter / this thing.' Borrowed from English slang ('Gucci' = good/important), it filtered into informal Korean speech to signal that something is a serious affair.
Baek Sang-gil compares managing threats to pruning an apple tree — you must cut troublesome shoots early, before they grow. This kind of agricultural metaphor for political or criminal control is a well-worn trope in Korean crime dramas, echoing the real-world imagery that powerful figures use to sound philosophical while ordering violence.
'깨를 볶다' (literally 'roasting sesame seeds') is a Korean idiom for a couple acting lovey-dovey in public — the kind of sweet, slightly cringe-worthy affection that makes bystanders feel like third wheels. Maeng-suk uses it while watching Tae-ha and Eun-sae zoom past on the motorbike.
Hee-ja says Tae-ha has become '최수종' — Choi Soo-jong is a beloved Korean actor famous since the 1990s for playing devoted, gentle romantic leads. Calling a man 'Choi Soo-jong' is a shorthand for saying he has turned into a completely whipped, sweet-hearted boyfriend.
오마카세 (omakase) — the Japanese chef's-choice tasting-menu format — has become a major dining trend in Seoul, especially in the upscale Cheongdam-dong neighbourhood. A single seat can cost hundreds of thousands of won. Eun-sae's excitement at the TV segment hints at the kind of lifestyle she may have enjoyed before losing her memory.
In South Korea, becoming a 국가대표 (national representative / national team member) is considered an enormous honour and a rare achievement. Hee-ja's cutting point is that even reaching that elite level didn't protect Tae-ha from ending up in organised crime — making it the worst possible outcome in her eyes for her son.
