The on-screen text reads 역량기 (力量記), roughly 'Chronicle of Power.' K-dramas often use stylised chapter titles mid-episode to signal a turning point in the story. Here it marks the moment right after Bong-soon channels everything she has to hurl the bomb skyward.
Bong-soon promises to replace Min-hyuk's ruined clothes once her 월급 (wol-geup, monthly salary) comes in. South Korean workers are almost universally paid on a fixed monthly schedule rather than weekly, so promising something 'when my paycheck arrives' is a very common everyday expression of delayed generosity.
Bong-soon's line is a classic K-drama confession beat: instead of saying 'I like you,' she expresses her feelings indirectly through the emotion the moment brings her. Korean romantic expression often centres on how someone makes you feel rather than a direct declaration, making this kind of line quietly loaded with meaning.
원빈 (Won Bin) is one of Korea's most celebrated actors, famous for his striking looks in films like 'Mother' (2009). The joke is that the poem about an impossibly perfect person is simply titled with his name, treating 'Won Bin' as a synonym for unattainable beauty — a pop-culture shorthand any Korean viewer would catch instantly.
The poem's title 닭 쫓던 개 지붕 쳐다본다 ('the dog that chased the chicken now stares at the roof') is a well-known Korean proverb. It means someone who worked hard toward a goal ends up with nothing and can only watch helplessly as the chance escapes — the punchline that 'the chicken had long legs' is the students riffing on the familiar saying.
둘리 (Dooly) is the hero of the beloved Korean cartoon 'Dooly the Little Dinosaur' (아기공룡 둘리, 1983–present), a baby dinosaur from prehistoric times who lands in modern Seoul. When Bong-soon jokes she is 'not Dooly' and therefore can't just 'leave Earth,' she is poking fun at the idea that she is some kind of alien being — a running gag about her superhuman strength.
Min-hyuk and Guk-du meeting at a bar to sort out their rivalry over Bong-soon follows a deeply ingrained Korean social script: serious personal matters, especially male competition, are often aired over 맥주 (beer) or 소주 at a 호프집 (hof-jip, a casual beer bar). The ritual of pouring for each other — even grudgingly — implies a mutual acknowledgment that this conversation has to happen.
가출 (ga-chul) literally means 'leaving the house without permission' and in Korean is almost always used for a teenager running away from home. Applying it to a middle-aged father is the joke: the word choice makes him sound like a sulky teen, and the family's immediate assumption that mom must have hit him again adds to the absurdity.
궁합 (gung-hap) is a traditional Korean practice of checking whether a couple's birth dates and times are compatible before marriage, usually done by a fortune-teller (사주쟁이). Bong-soon's mom asking Min-hyuk for his 생년월일시 (birth year, month, day, and hour) is not small talk — it is the classic first step a Korean mother takes to vet a potential son-in-law.
Min-hyuk reveals he had Bong-soon wear a 방탄복 (bang-tan-bok, bulletproof vest) made from '최첨단 소재' (cutting-edge materials). The word 방탄 is also famous internationally as part of the group name BTS (방탄소년단, Bangtan Sonyeondan — 'Bulletproof Boy Scouts'), though here it is used entirely in its literal sense.
