태릉 (Taereung) National Training Center
0:24
태릉 (Taereung) is South Korea's elite national sports training facility in Seoul, where athletes selected for national teams live and train together under strict schedules. Being sent there is a huge honor — it means you've made the national team (국가대표, gukgadae). The campus is famous for its intense, almost military-style discipline, including mandatory lights-out times, which is exactly why Bok-joo is sneaking to a quiet corner just to make a phone call.

Homesickness and comfort food
0:59
Bok-joo isn't just missing people — she specifically longs for the fried chicken her dad and uncle make at 복치킨 (Bok Chicken), the family's chicken shop. In Korea, fried chicken is deeply tied to family and comfort, and a homemade batch from a loved one carries a whole different emotional weight than ordering delivery. Mentioning food alongside family is a very natural way Koreans express that they feel the warmth of home slipping away.
#
조카사위 (joka-sawi) — nephew-in-law
3:48
When Bok-joo's uncle immediately calls Joon-hyung '조카사위' (joka-sawi, nephew-in-law), he's using a real Korean kinship term for the husband of one's niece — even though they aren't engaged yet. Koreans often apply family titles pre-emptively when they approve of a relationship, which is both a warm blessing and a little bit of playful pressure on the couple.
#
Taereung dating curse
6:12
The senior athlete's warning that roughly 90 percent of athletes who enter Taereung break up with their partners is a well-known piece of sports culture lore in Korea. The intense isolation, rigid schedules, and total focus on competition make maintaining outside relationships genuinely difficult, so this fear is real and widely talked about among student-athletes — not just dramatic gossip.
#
증거 (Proof) and confrontation culture
8:28
Nan-hee's insistence that you need hard evidence before you confront someone — or even form a plan — reflects a pragmatic streak in how young Koreans approach relationship conflicts. Catching someone '현장에서' (hyeon-jang-eseo, in the act, at the scene) is the gold standard; hearsay alone is not considered enough to act on, even among close friends who are already suspicious.
#
황운동 (Hwang-undong) sports medicine
17:01
The coach refers Bok-joo to a specific clinic in 황운동 (Hwang-undong), a neighborhood known in Korean sports circles for its concentration of specialized orthopedic and rehabilitation clinics catering to athletes. It's common for coaches to maintain a personal list of trusted doctors for their athletes rather than sending them to a general hospital — the relationship between coach and sports doctor is an important part of the support network.
#
인사 (Insa) — greeting elders
22:33
Joon-hyung desperately tries to steer Bok-joo away before she can go in and greet her father, because a formal 인사 (insa, greeting) to a parent is a serious, sit-down moment in Korean culture — not something you can rush past. Letting her do it would mean she'd linger inside, discover the closed sign, and find out about the surgery. Blocking the greeting is the only way to control what she learns.
#
꿀 떨어진다 (Honey dripping eyes)
27:35
The expression 눈에서 꿀이 떨어진다 (eyes dripping honey) is a popular Korean idiom for the way someone looks at a person they're completely smitten with — their gaze is so sweet and adoring it's like honey pouring out. Bok-joo uses it to compare how Joon-hyung used to stare at her versus now, which is both a complaint and a confession of how much she misses feeling adored.
#
가게 임시 휴업 (Temporary business closure) notice
37:45
The handwritten sign on 복치킨's door — apologizing for the temporary closure due to 'the owner's circumstances' — is a completely standard sight on small Korean family businesses. Rather than explain the real reason (a hospital stay), owners use this vague, polite formula to avoid worrying regulars. The sign is such a normal fixture that neighbors accept it without question, which is exactly why it almost doesn't tip Bok-joo off immediately.
#
밴댕이 소갈딱지 (Tiny anchovy heart)
40:53
When Bok-joo calls herself a '밴댕이 소갈딱지' (baendaengi sogaldakji), she's using a beloved Korean insult that translates roughly as 'someone with a heart as small as the inside of a tiny anchovy.' Koreans have long used the sprat-like 밴댕이 fish — whose guts are famously minuscule — to describe a petty or narrow-minded person. Using it on yourself is a very Korean way of making a sincere, self-deprecating apology.
#
노적성해 (Dewdrops filling a sea)
50:15
The professor fumbles the four-character Chinese idiom 노적성해 (露積成海, nodong-seonghae — dewdrops accumulating to form a sea), meaning small efforts add up to something vast. These Sino-Korean cheongjageo (four-character idioms) are still used in formal speeches in Korea, especially at academic ceremonies. The moment is funny precisely because professors are expected to deliver them flawlessly, and a student has to quietly rescue him.
#
말년휴가 (End-of-service leave)
53:51
Tae-kwon announces he's on '말년휴가' (mallyeon-hyuga), the special leave granted to Korean soldiers in the final weeks of their mandatory military service — a moment almost every Korean man celebrates. The fact that he timed it exactly for the graduation is a big deal; mal-nyeon (말년, end of service) is the light at the end of a roughly 18-month tunnel, and showing up in civilian clothes to cheer on his friends is a classically dramatic K-drama pay-off.
#
사돈 (Sado n) — families of a couple meeting
54:37
When Joon-hyung introduces both sets of parents to each other and his uncle uses the term '사돈어른' (sadon-eoreun, honorable in-law family member), it signals a full-blown informal 상견례 (sanggyeonre) — the first official meeting of both families that traditionally precedes an engagement. Even though no proposal has been formally made yet, both families sliding into 사돈 language means everyone is already treating this as a done deal.
