A 재정 증인 (jaejeong jeungin) is a witness summoned at the court's own discretion rather than by either party. Vincenzo is exploiting this mechanism to get himself onto the stand despite being connected to the plaintiff's side — a cheeky procedural manoeuvre that Korean viewers would immediately recognise as bending the rules.
Han-seo mangles Vincenzo's name into '빙신조,' which sounds almost identical to '병신조,' a crude insult meaning something like 'idiot Zo.' Korean wordplay like this — swapping one syllable to sneak in an insult — is a staple of comedy and playground teasing, and the fact that Han-seo does it accidentally-on-purpose tells us a lot about how he really feels.
Cha-young shouts '플렉스 해 줄게!' — borrowed directly from English hip-hop slang, 'flex' entered Korean youth culture around 2018–2019 and means showing off wealth or spending lavishly. Buying ten bespoke suits as a work bonus is her very on-brand version of flexing.
The tailor shop they visit is a 맞춤 양복 (custom suit) atelier — a tradition still thriving in neighbourhoods like Jongno and Euljiro in Seoul. Getting a suit 맞추다 (made to measure) rather than buying off the rack is a marker of serious taste and money in Korean professional culture, which is why Cha-young's offer of ten suits is such a big deal.
차박 (chabak) — sleeping in your car as a camping trip — exploded in popularity in South Korea around 2020–2021 as a low-cost, socially-distanced outdoor activity. Pairing it with 감바스 (gambas al ajillo, garlic shrimp cooked in a pan) became a cliché of Korean outdoor food culture, so the investment-team manager rattling off this list instantly marks him as a very typical Korean weekend dad.
손흥민 (Son Heung-min) is South Korea's most celebrated footballer, playing for Tottenham Hotspur in England. Being called '제2의 손흥민' — the next Son — is the highest possible compliment for a young Korean player. The news report sets up the plot device of a European scout looking for Korean talent, something that resonates deeply with Korean sports fans' dreams of overseas success.
준우's father told him as a schoolboy to live a life that could never be written as a 위인전 (uiinjeon) — a biography of a great, virtuous person, the kind every Korean schoolchild reads. The line is a chilling piece of corporate-villain parenting: greatness in business, he implies, requires deeds too dirty to be celebrated.
The homeless man's name 길벗 literally means 'companion on the road' (길 = road, 벗 = friend) — a poetic old Korean word. The residents initially mishear it as 'Gilbert,' assuming it is a foreign name, and the correction gets a big laugh because the pure Korean word sounds unexpectedly Western.
서초동 (Seocho-dong) is the neighbourhood in Seoul where the Supreme Court, prosecutors' offices, and countless law firms are clustered. When Cha-young says 서초동 gossip spreads instantly, she means the tight-knit legal community there is essentially a small village — everyone knows everyone's business, especially embarrassing failures like Myeong-hui's bungled bribe attempt.
부가세 (bugase) is South Korea's Value Added Tax, and small business owners must file returns twice a year, with one deadline in late January. Miss Yang stopping the gangsters mid-departure to collect meal receipts for her VAT filing is pitch-perfect: no matter how dramatic the situation, Korean small-business tax admin waits for no one.
