The line draws on the saying '매도 먼저 맞는 게 낫다' — roughly 'it's better to be hit first than to wait for the blow.' The idea is that facing an unpleasant thing early is preferable to dreading it. The minister is spinning the protesters outside as an advantage: the backlash arrived fast, so now they can deal with it and move on.
'원조 교제' (weonjyo gyoje) literally means 'compensated dating' — a term for teenagers receiving money or gifts from adults in exchange for companionship or sexual contact. Listing it alongside gambling, drugs, and gangs is the minister's way of painting Korean schools as dangerously out of control, justifying the new disciplinary agency.
Every November on 수능 (Suneung) day — South Korea's all-important college entrance exam — the government actually does restrict flights over test centres during the 40-minute English listening section, and even delays departures nationwide. It's a real policy that signals just how seriously Korea treats the exam, and the politician uses it as shorthand for how passionate Koreans are about education.
'보호비' literally means 'protection fee.' Collecting it from younger or weaker students is a classic marker of school 일진 (iljin) culture — informal gangs of delinquents who dominate a school's social hierarchy. The new transfer student handing over cash immediately marks him as a target in the school's pecking order.
'파밍' is slang borrowed from gaming — 'farming,' meaning to grind for resources or points. Here it means the lower-ranked students are going out to fight each other so a higher-ranking gang boss can scout the strongest ones. The whole school hallway brawl is essentially a tryout, with violence as the performance metric.
'짱' means the top fighter or leader of a group, and '통합 짱' means the overall boss across multiple cliques or departments — here, all three years of the school. Korean vocational high schools in dramas often depict this kind of tiered delinquent hierarchy where lower 짱s owe allegiance to one supreme figure.장권혁 sits at the very top of that pyramid.
Stuffing crumpled newspaper inside wet shoes to absorb moisture overnight is a well-known Korean household tip — the kind of practical knowledge passed down rather than looked up. The character doing this quietly for the transfer student is a small but meaningful act of care, showing a nurturing side beneath a rough exterior.
The teacher's joke about making textbooks 'the Joseon Dynasty way' refers to the era before printing was widely accessible, when students hand-copied texts character by character as their primary learning method. Telling delinquents who showed up without books that they'll reproduce the material by hand is both a punishment and a sly history lesson.
'보안 사항' means 'classified information.' The National Intelligence Service (국정원, Gukjeongwon) is South Korea's equivalent of the CIA, and personnel linked to it — or to special-forces black operations — can have career records sealed even from parliamentary intelligence committees. The brief four-character entry on the supervisor's file is the show's way of signalling he has a covert past.
'특전사' is the ROK Army Special Warfare Command — South Korea's elite airborne special forces, often compared to the U.S. Green Berets. '특임대' refers to a special-mission unit within that command. A captain-level officer from this background would have advanced combat and restraint training, which explains how one person could physically subdue an entire school of violent teenagers.
Tattoos (문신) carry strong social stigma in South Korea, historically associated with organised crime (조폭, jopok). While adults are legally free to have them, banning them on school grounds is portrayed here as a deliberate signal — the ministry is targeting the visual culture of gang affiliation. The scene where the announcement plays while someone's tattoo is visibly being removed makes the policy literal and darkly comic.
'MZ' is a Korean shorthand for the Millennial-Gen Z demographic. '조폭' (jopok) means organised crime syndicate. The phrase 'MZ 조폭' describes a newer phenomenon of youth gangs that recruit members through Instagram DMs and group chats rather than face-to-face initiation — exactly how 장권혁's DM to the boys was portrayed earlier in the episode.
의성 (Uiseong) is a county in North Gyeongsang Province famous for its garlic, and garlic-flavoured sausages from that region are a beloved cheap snack found in Korean school and workplace vending machines and convenience stores. Listing this ₩2,200 sausage alongside cash and a pair of Nikes in an official expense report is the episode's closing joke — deadpan bureaucratic absurdity.
