The group toasts with both Korean 짠 (jjan) and Japanese 간빠이 (kanpai) — the Korean word is pure onomatopoeia for clinking glasses, while kanpai literally means 'dry cup.' Mixing the two is a small, playful nod to the cross-cultural chemistry at the heart of the show.
에노시마 (Enoshima) is a small island near Kamakura, about an hour from Tokyo, famous for its sea-caves, shrine, and sunset views. It is one of the most iconic romantic day-trip spots for couples in Japan, so a photo taken there carries an instant 'romantic backstory' implication that Korean viewers would immediately feel.
The '국제 밤하늘 협회' is the real International Dark-Sky Association (IDA), a US-based nonprofit that certifies locations worldwide as Dark Sky Places to protect them from light pollution. South Korea has a certified site — Yeongyang Firefly Eco-Park in North Gyeongsang Province — making this a concrete, real-world destination the characters could actually visit together.
자갈치 시장 (Jagalchi Sijang) in Busan is South Korea's largest seafood market, famous for its raw fish stalls, pojangmacha (street-food tents), and lively atmosphere day and night. Locals treat it as a go-to place to drink and eat fresh hoe (회, raw fish) with friends, which is exactly what the women are doing here.
용우 (Yong-u) explains he grew up speaking two dialects: his mother's Busan 사투리 (satoori, regional accent) and his father's standard Seoul Korean. Busan dialect is the most distinctive regional variety in South Korea — faster, more melodic, and with different verb endings — so a Seoul speaker hearing it for the first time often needs a moment to adjust, hence the women's surprised reaction.
The scene reveals that Mu-hui's mother put sleeping pills or poison into a birthday cake hoping to die together with the family — a real pattern sometimes called 동반자살 (dongban jaSal, joint suicide or family suicide pact) in Korean news. This note flags the content: the drama depicts a parent's attempt to kill herself and her child.

무희 talks back to the vision and tells it to disappear so she can be free — a turning point the drama frames as her finally separating her own identity from her mother's. In Korean psychological drama, the idea that naming and confronting a trauma allows you to 'escape' it (벗어나다) is a common narrative device rooted in the concept of 한 (han), the deeply held sorrow or grief that Koreans believe must be released rather than suppressed.
호진 (Ho-jin) looks at a photo and notes how much Mu-hui resembles her biological mother. In Korean culture, the idea that a child is the 'mirror' of a parent — physically and temperamentally — carries strong weight; the aunt's decades of fear and coldness toward Mu-hui make sense to a Korean audience through this lens, even if it remains deeply unjust.
용우 asks to take 고추장 (gochujang, fermented red chili paste) and 맛간장 (mat-ganjang, seasoned soy sauce) to the UK — two staples that Koreans living abroad treat as irreplaceable. Home-made versions, especially 어머니표 (mother's-style), are considered far superior to store-bought, which is why he specifically praises 형님's mother's batch.
할아버지 Yun Won-jae is revealed to own a 디킨스 초판본 — a first-edition Charles Dickens novel. Rare foreign first editions are prized in Korean antiquarian-book culture, and the comedy here is that 호진 casually almost keeps it until 무희 spots what it actually is. It also echoes the earlier plot thread about donating the grandfather's 고서 (古書, old books) to a university library.
무희 snaps at the producer with the idiom '다 된 국에 발가락 담그다' — literally 'dipping your toe into finished soup.' It means barging in and claiming credit (or disrupting things) at the very last moment after everyone else did all the hard work. The image of sticking a dirty toe into a pot of ready-to-serve soup makes the rudeness of the act very vivid.
무희 arrives at the dark-sky observatory clutching a bundle of 클로버 (clover) she has been collecting throughout the series as a personal good-luck ritual. Finding a four-leaf clover (네잎클로버) for luck is a widely shared superstition in Korea just as in the West, but her collecting them 'by the bunch' is a running joke about how desperately she has been hoping for clear skies — and, by extension, a clear future.
