수능 (su-neung) is South Korea's national college entrance exam, taken once a year in November. A student's score determines which universities and which departments they can apply to — so a bad score genuinely locks you out of your preferred major. The father's frustration here is that a poor 수능 result leaves his son with very little room to be choosy about his course of study.
점호 (jeom-ho) is a mandatory nightly roll call held in Korean university dormitories, usually at a set time — miss it and you can face punishment or even expulsion from the dorm. It functions a bit like military-style attendance, and getting locked out before 점호 ends is a genuine crisis for a resident student.
학식 (hak-sik) is short for 학교 식당, the subsidised cafeteria run by a university. Because tuition and campus life are tightly budget-conscious for Korean students, a price hike in 학식 is a real flashpoint — cheap, reliable cafeteria meals are considered a basic student right, which is why the protesters are demanding the school board explain itself.
Many Korean universities in the 1990s had an on-campus 방송반 (bang-song-ban), a student broadcasting club that ran the campus PA system and produced live radio-style programmes. Because these clubs controlled the campus-wide speaker network, an accidental open-mic moment — like the argument overheard here — would genuinely broadcast to every building on campus.
삼겹살 (sam-gyeop-sal) — thick slices of pork belly grilled at the table — is one of Korea's great comfort foods and a staple of casual social eating. Ordering it alone is seen as slightly sad because the whole experience is built around sharing, turning the meat together, wrapping it in perilla leaves, and pouring each other's drinks. His admission that he has no one to eat it with is an indirect confession of loneliness.
미세먼지 (mi-se-meon-ji), the fine particulate pollution that blankets Seoul on bad days, had not yet become a topic of daily life in 1999. It only entered mainstream Korean vocabulary around the 2010s, when air-quality apps and face-mask routines became normal. A character mentioning 미세먼지 and 'Chinese-made air' in a 1999 setting is one of the show's running jokes about the time-travellers accidentally revealing future knowledge.
The chant — 'A people who forget their history have no future' — is a famous line attributed to the independence activist 단재 신채호 (Sin Chae-ho), though historians debate its exact origin. It became a rallying cry for Korean nationalism and is especially beloved by history (사학과) students and departments. Using it as a cheer at a department party is both a genuine expression of pride and a running in-joke about how seriously historians take themselves.
Ordering 반반 (ban-ban) — half plain fried (프라이드) and half sweet-spicy glazed (양념) — is practically a national ritual when Koreans order chimaek (chicken and beer). It became the default group order precisely because it lets everyone have both styles without committing to one. The sheer delight in shouting '반반!' here captures how central this small choice is to Korean social eating.
시집 가다 literally means 'to go to the husband's house' and is the standard Korean phrase for a daughter getting married. The mother's teasing — 'Are you getting married? Why else would you do the dishes?' — reflects the traditional expectation that girls learn housework in preparation for married life, and that doing chores voluntarily at home is so unusual it must signal something big. The daughter's gentle pushback is a small generational clash.
장모님 (jang-mo-nim) is the formal, respectful term a son-in-law uses for his wife's mother. Dropping to his knees and calling her 장모님 in front of the family home is an immediate social signal — it tells her exactly who he is and what his relationship to her daughter is, without needing to say another word. In Korean culture, the sudden use of this title by a stranger at the door would be stunning.
