The senior athlete tells Bok-joo to meet at 태릉 (Taereung), shorthand for the 태릉선수촌 — South Korea's elite national athletes' village on the outskirts of Seoul. Being invited to train there is a big deal; it means you are on the radar of the national squad selectors.
이선수rattles off today's 학식 (학생 식당 — student cafeteria) menu: 제육 (spicy stir-fried pork), bean-sprout soup, braised black beans, stir-fried anchovies, and a small yogurt drink. University cafeterias in Korea serve a rotating hot-meal set for a subsidised price, and athletes on tight budgets depend on them heavily.
The team cheers about going to 쇠판 — literally "iron plate." It is a slang nickname for the student cafeteria, a playful reference to the metal meal trays used there. For weightlifters who spend their days around iron barbells, the double meaning makes the word especially fitting.
The weightlifters grumble that their old practice hall was taken over by the 리체부 (리듬체조부 — rhythmic gymnastics team). The two sports sit at opposite ends of the Korean athletic image spectrum: rhythmic gymnastics is associated with slender, glamorous athletes who receive heavy media and sponsorship attention, while weightlifting is seen as unglamorous grunt work. This real cultural tension between the two sports runs throughout the show.
Bok-joo's uncle teases the three friends by calling them 도, 미, 솔 — the Korean names for the musical notes Do, Mi, and Sol. It is a light-hearted way of saying the three of them are always together in a set, like a chord, poking fun at how inseparable they are.
Coach Yoon recalls the 미국 애틀란타 올림픽 (1996 Atlanta Games) and the agony of cutting 4 kg in a week to make a new weight class. Dehydration methods like saunas and spitting were common in Korean combat and lifting sports at the time; the story is meant as a cautionary tale about letting weight creep up in the off-season.
The girls debate choosing between 송중기 and 김수현, two of the biggest Hallyu (Korean Wave) heartthrob actors of the mid-2010s. 송중기 had just finished the mega-hit drama Descendants of the Sun, and 김수현 was famous for My Love from the Star — name-dropping them signals peak fan-culture wish-fulfillment.
The on-screen title announces a 국가대표 선발전 — a national representative selection competition. In Korean sports, making the 국대 (국가대표 — national team) is the central goal of a university athlete's career; failing the first round, as Song Si-ho does here, is a significant and public setback.
Song Si-ho tells Bok-joo she has just come back from 태릉 after failing to make the national team. Athletes who are cut from the squad at Taereung must return to their university dorms, which can feel like a humiliating step backward. Sharing a room with a weightlifter she once looked down on adds an extra layer of irony.
Bok-joo washed Joon-hyung's handkerchief before returning it, meaning well, but he is annoyed rather than grateful. In Korean social norms, handling someone's personal item without permission — even to clean it — can feel like an overstep, especially between people who are not yet close. His reaction is exaggerated for comedy but rooted in that real sense of boundary.
