수능 is the nationwide university entrance exam taken once a year, usually in November. It is one of the most high-pressure events in a Korean student's life, and jokes about 'losing a screw after 수능' — meaning a top student suddenly acting scatterbrained once the pressure is off — are a familiar piece of Korean humour.
In Korean Buddhist tradition, the soul of the deceased is believed to wander for 49 days after death before passing on to the next realm. Families hold memorial rites every seven days during this period. Yuri choosing exactly 49 days is not arbitrary — it maps directly onto this deeply rooted belief about how long a spirit lingers in the human world.
정동진 is a small coastal village on the East Sea famous for its sunrise views and seafood. Koreans frequently bring back regional food gifts — called 특산물 (teuksanmul, local specialties) — when returning from travel, and receiving dried seaweed (미역) from a coastal town is a perfectly ordinary neighbourly gesture.
A 무당 is a female ritual specialist in Korean shamanism (무속신앙) who communicates with spirits, performs exorcisms, and holds gut (굿) ceremonies. The ability to see and talk to the dead is considered a defining sign of the 신기 (divine gift). Yuri matter-of-factly claiming the title here plays on the familiar cultural archetype.
납골당 are the facilities where cremated remains are stored in Korea, increasingly common as burial land has become scarce. They function somewhat like a community for the deceased in Korean folk belief, which is why the ghost characters treat it as an organised place with its own social network and search parties.
Korean convenience store chains like GS25, CU, and 7-Eleven sell freshly prepared hot foods — 떡볶이 (spicy rice cakes), 오뎅 (fish cake skewers in broth), instant ramen with a boiling-water station, and even 족발 (braised pork trotter) in vacuum packs. Eating a full meal at the 편의점 is completely normal, especially for younger Koreans or those living alone.
Koreans often jokingly identify as 소주파 (soju people) or 맥주파 (beer people), treating the preference as a personality type. 소주 is a clear distilled spirit usually around 16–25% alcohol, and choosing it straight rather than mixing it in a 소맥 (soju-beer blend) marks someone as a no-nonsense drinker — a source of both pride and teasing.
Korean preschools and kindergartens regularly hold 부모 참관 수업 — structured lessons that parents sit in on and sometimes participate in alongside their child. Attendance is treated as a parental duty, and showing up smartly dressed or enthusiastic is a form of social performance among the parent group, which is exactly what Geun-sang is joking about.
양파링 (Onion Ring) is a hugely popular Korean ring-shaped corn snack made by Haitai. Hajun answering 'C' with 'Yangpa-ring' instead of the letter itself is a classic young-child logic moment — a ring shape looks like the letter O or C, and the snack is one of the first 'ring' things a Korean toddler knows. The adults' laughter shows it landed perfectly.
Strawberry is one of the more common childhood food allergies in Korea, and Korean preschools keep careful allergy records shared with all staff. The fact that Yuri — as a supposed new kitchen helper — does not know Sewoo's strawberry allergy is a glaring sign to observant viewers that she is not who she claims to be, since a birth mother would know this immediately.
Korean hospital nurses are assigned to specific wards and can receive 발령 (ballyeong), an official departmental transfer order. Being moved to the 부인과 (women's health / OB-GYN ward) is significant narrative positioning — it places Minjung directly in the space where birth, life, and maternal identity are most concentrated.
