When Hye-jin says something unlucky out loud, Mi-seon tells her to grab a tree and spit three times ('퉤퉤퉤'). This is a Korean folk remedy for accidentally speaking bad luck into existence — the spitting wards off the jinx, similar to the Western habit of knocking on wood.
Hye-jin's point that dreams still require a university degree lands hard because South Korea's 수능 (college entrance exam) culture is one of the most intense in the world. A student's entire future career path is widely seen as hinging on which university they get into, making grades feel existential rather than just academic.
The civil servant mutters '답정너,' short for '답은 정해져 있고 너는 대답만 해' — 'the answer is already decided, you just have to say it.' It's a popular Korean expression for when someone asks a question but clearly only wants to hear one specific answer.
Du-sik describes Seong-hyeon as a '먹방' (mukbang) creator — someone who films themselves eating large amounts of food, often live, while chatting with viewers. The format started in South Korea and became a global phenomenon; Grandma Gam-ri has clearly never heard of it, which is the joke.
The '등대가요제' is a fictional small-town singing competition, but it mirrors real 가요제 (song festivals) held all over Korea at local holidays and community events. First prize is ₩3 million (about $2,200 USD) — serious money for a village contest, which is why everyone suddenly wants in.
Du-sik says jumping on stage means sharing Ju-ri's '쪽팔림' (embarrassment) so she isn't alone in it. In Korean social life, public humiliation carries real weight — it affects not just the individual but those around them. His willingness to absorb half the shame is framed here as genuine care, not just comic relief.
DOS (도스) is the fictional boy group Ju-ri obsesses over throughout the series. Their surprise guerrilla live — an unannounced pop-up performance — is a real K-pop marketing tradition where idols appear at public locations with no warning, whipping fans into a frenzy exactly the way we see here.
Hye-jin's father explains that the '행운목' (lucky bamboo dracaena) flowers only once every seven years, and whoever witnesses the bloom is said to receive once-in-a-lifetime good fortune. The plant has been sitting unnoticed in her clinic — the blooming flower works as a quiet signal that something life-changing is on its way.
After nearly falling into the water, Du-sik jokes he almost went to meet '용왕님,' the Dragon King who rules the undersea palace in Korean mythology. The phrase is a colorful way of saying he nearly drowned — equivalent to saying he almost 'met his maker' at the bottom of the sea.
