임한림 asks 식사하셨습니까? — literally "Have you had a meal?" — as a greeting rather than a genuine question about food. In Korean culture, asking whether someone has eaten is a common way to show care and acknowledge another person, similar to saying "How are you?" in English. It carries warmth without expecting a literal answer.
나화진 mentions watching 천상열's lectures on EBS 인강 (인터넷 강의, internet lectures). EBS — Korea's public educational broadcaster — provides affordable online classes that millions of students use to prepare for the 수능 (college entrance exam). Passing 육사, the Korea Military Academy, is an extraordinarily competitive achievement, so crediting a single teacher's EBS course carries real emotional weight.
The shot lingers on the hanja character 忍 (참을 인), meaning "endurance" or "to bear/suppress." Koreans often write or display this character as a personal reminder to keep their temper in check. The fact that 나화진 mutters that he should not be made to write it signals he is dangerously close to losing his composure.
SKY (스카이) is the informal name for Korea's three most prestigious universities — Seoul National University (서울대), Korea University (고려대), and Yonsei University (연세대). Getting in on a full scholarship (장학금) is considered the gold standard of academic success, making it shorthand here for an almost unreachable level of achievement that박현웅 is apparently throwing away.
미미미누 is a real, hugely popular Korean YouTube channel that began as study-with-me and exam-prep content and grew into a broader entertainment channel beloved by high school students. A teacher appearing on the channel would immediately go viral among teenagers, which is exactly why 천상열 agreed to it. The name is a playful nonsense handle with no literal meaning.
순대 is a beloved Korean street food made by stuffing pig intestines with glass noodles, vegetables, and sometimes pork blood, then steaming or boiling them. It is cheap, filling, and strongly associated with 포장마차 (street stalls) and late-night study culture. The friends tearing into it during exam prep is a very familiar image for Korean students.
족보 literally means "family genealogy," but students use it as slang for collections of past exam questions — often photocopied and passed around secretly between classmates and schools. Having the right 족보 before midterms is considered a serious edge, which is why the friends are squabbling over who gets it first.
Korean college-entrance scores are divided into nine 등급 (grades), with 1등급 being the top roughly 4% and 9등급 the very bottom. When 천상열 tells 박현웅 his "grade" is 9, he is not talking about school year — he is delivering a devastating personal insult, telling the top-ranked student that he and his entire family belong at the lowest rung of society.
교권보호국 (Teacher Rights Protection Bureau) is the special agency at the centre of this drama. 교권 (교사 권리) means "teachers' rights," a real and hotly debated topic in Korea following several high-profile cases of teachers being assaulted, humiliated, or driven to suicide by students and parents. The show exaggerates the concept into a near-lawless enforcement body to explore those tensions.
후원의 밤 ("night of support") is a formal fundraising banquet where wealthy donors pay large sums to support a politician's campaign. They are a standard, legal part of Korean electoral politics but are also frequently associated with quid-pro-quo arrangements — exactly the corrupt exchange being arranged here between the candidate for 교육감 and the wealthy school mother.
The politician quotes Article 8 of the 교권보호국's founding law, which states that a supervisor's actions during an investigation cannot be restricted by other laws or agencies. 초법적 (超法的) means "above the law" or "extra-legal." This fictional clause is what has allowed the Bureau to act so aggressively all series — and it is now being used as a political weapon against them.
Reading out a list of named individuals — including sitting lawmakers, former prosecutors, and corporate CEOs — during a live 국회 (National Assembly) committee hearing is an extraordinarily explosive act in Korean political culture. Parliamentary proceedings are broadcast and the statements carry legal privilege, making it nearly impossible to suppress, which is precisely why 최강석 chooses this moment and this venue.
나화진 jokes that he simply told suspects he would go easy on the first one to talk — 한 놈만 불어, roughly "just one of you needs to confess." This is a well-known investigative bluff in Korean crime dramas and real-world interrogation, essentially a prisoner's-dilemma tactic. The punchline is that everyone talked, making the whole corrupt network collapse instantly.
