Korean police are legally required to state the specific charge aloud at the moment of arrest — here they name both the victim and the crime. This mirrors the Miranda-style rights reading that follows: the suspect must be told they can hire a lawyer and stay silent. Doing this on the spot, in front of witnesses, is standard procedure.
뉴트리아 are large, semi-aquatic rodents originally imported to Korea for fur farming. They escaped into the wild and became an invasive species along rivers and wetlands. The government offered a bounty — around ₩20,000 per animal — to encourage citizens to trap them, which is exactly what Seok-do is bragging about. Calling himself the 'Geumga-dong nutria' is his way of saying he's a scrappy, hard-to-kill predator from this very neighbourhood.
Hong-sik says he once 'ate knife rice' (칼 밥 먹다) inside an organisation — a blunt slang phrase meaning he lived the violent day-to-day life of a gang member. Leaving that world is often described as 'washing your hands' (손 씻다), and Hong-sik pre-emptively mocks that cliché, suggesting Vincenzo should skip the noble speech and just keep using his real skills.
믹스커피 is a single-serving sachet of instant coffee, powdered creamer, and sugar all pre-blended — you just tear it open and add hot water. It became a staple of Korean office culture and pojangmacha stalls from the 1970s onwards. Vincenzo saying he'll never forget the taste is a quiet admission that this humble drink has come to represent Korea itself to him.
영정사진 is the formal portrait displayed at a Korean funeral and placed on the ancestral altar. It is traditionally taken while the person is still alive, often in their best clothes, with a neutral background. Gyeong-ja wanting one done now — knowing she is gravely ill — is a quietly devastating act of practical preparation rooted in Korean funeral custom.
At Korean drinking parties, a 흑기사 ('black knight') is someone who volunteers to drink a penalty shot on another person's behalf — a gallant gesture. 흑장미 ('black rose') is the same role played by a woman. The crowd chanting these terms is pressuring someone at the table to step up and take Vincenzo's drink for him, a beloved ritual in Korean 술자리 (drinking gatherings).
당근마켓 — literally 'carrot market' — is Korea's dominant neighbourhood second-hand trading app, similar to Craigslist or Facebook Marketplace but hyperlocal: you can only buy and sell within a few kilometres of your GPS location. Ju-seong casually mentioning he sold the expensive kopi luwak beans there because he couldn't be bothered brewing them is a very relatable, very Korean punchline.
Vincenzo switches to Italian and quotes what the show translates as 'catch a big fish with a small lure.' Using Italian at key strategic moments is a recurring character tic — it signals that he is shifting from emotional thinking into cold, calculating Mafia-consigliere mode. The subtitle card the writers add ('자막') is a meta-joke acknowledging that even the Korean characters need the translation.
붕어빵 are iconic Korean winter street snacks — batter pressed into a carp-shaped iron mould and filled with sweet red-bean paste or, more recently, custard cream (슈크림). Vendors push small carts and sell them cheaply, often three for ₩1,000. Cha-young immediately claiming the cream-filled one without hesitation is a small, warm moment of domesticity between two people who are otherwise navigating very dangerous territory.
묻지 마 범죄 literally means 'don't-ask crime' — an attack on a stranger with no apparent motive, often triggered by the perpetrator's personal frustration or mental state. The term entered Korean public discourse after several high-profile random stabbings and became shorthand for unpredictable street violence. Vincenzo using it here is both a question and an accusation — he is forcing the attacker to label his own act.
South Korea became one of the world's largest sources of international adoptees from the 1950s through the 1980s, with tens of thousands of children sent abroad. Reunion between adoptees and their Korean birth families is a recognised, emotionally loaded phenomenon, and Jang Han-seok weaponising this fact — killing a mother days after her first reunion with her son — is framed as a deliberate escalation to maximum cruelty.
따까리 is informal Korean slang for the lowest-ranked helper in a hierarchy — someone who fetches coffee, runs errands, and has no real authority. Han Seung-hyeok using it to describe what he would have been without Myeong-hui's patronage is meant as a stinging insult to her investment in him, and her explosive reaction shows exactly how much the word lands.
