사부 (sabu) is a Korean adaptation of the Chinese term 師父, meaning a martial-arts or skills master. It sits above a regular teacher (선생님) and implies a deep, almost family-like bond between mentor and disciple. Using it here signals that the younger characters see this person as far more than a simple instructor.
호란 addresses her older brother as 오빠 (oppa), the standard term a younger sister uses for an older brother in Korean. The threat to 'send her flying into the ceiling' is spoken in blunt 반말 (banmal), the informal speech level used inside families — it marks intimacy even inside a threat, which is very typical of Korean sibling dynamics.
'분더킨더' is a Korean phonetic spelling of the German word Wunderkinder, meaning 'wonder children' or child prodigies. The drama uses it as the name of the antagonist group, and the characters immediately notice it sounds kind of cool — a wry reaction to discovering that even scary villains pick catchy names.
MOU stands for Memorandum of Understanding, a formal cooperation agreement common between Korean companies, universities, and government agencies. Using it here to describe a personal relationship is a deadpan joke: the speaker is wrapping up an awkward emotional admission in cold corporate language to avoid sounding sentimental.
깽값 (kkaeng-gap) literally means 'damage money' — cash demanded on the spot to settle a fight or an insult, like an informal street fine. Asking 'do you have 깽값?' is essentially daring someone: can you afford the consequences of hitting me? It is classic tough-kid banter rather than a formal legal threat.
'세상에 이런 일이' (There Are Such Things in This World) is a long-running KBS reality programme that reports on bizarre or extraordinary real-life stories. Shouting the title at the sight of an enormous cockroach is a comedic reflex — the characters are treating the absurd moment as if it belongs on that show.
'킹전복' means 'king abalone,' and 여사 is a respectful title for a businesswoman or matron, similar to 'Madam.' Giving the grandmother a seafood-trade nickname is a very Korean way of identifying a self-made market woman by her signature product — think of the powerful 아줌마 merchants famous in Korean traditional markets.
보육원 (boyugwon) are government-registered residential care facilities for children without guardians. Until major welfare reforms in the 2010s, they were the default placement for abandoned or orphaned children in Korea and often housed large numbers of kids in institutional settings — making a 'mass lock-up' scenario there especially chilling to a Korean viewer familiar with their history.
The phrases '표적이 따르리라' (signs shall follow) and repeated '할렐루야' (Hallelujah) mirror the high-energy call-and-response style of Korean Pentecostal and charismatic church rallies, which are enormously popular and recognisable in Korea. Framing a character as a '목자님' (shepherd-pastor) with a crowd chanting back is a sharp satirical signal about the group's cult-like structure.
'팔도강산' (Paldo Gangsan) means 'the eight provinces and rivers of Korea' and refers to the whole country. The song that plays lists real landmarks — Seoraksan, Gyeongpo Beach, Bulguksa temple, Cheomseongdae observatory — in a cheerful tour of the peninsula. It is a well-known piece that older Koreans often associate with road trips and national pride.
땡처리 (ttaengcheori) means selling off remaining stock cheaply at closing time, and it is a widely-used tactic at Korean 빵집 (bakeries). Customers who know the schedule will deliberately time their visit for the last hour to get cakes and bread at a steep discount — it is a familiar frugal habit, especially for younger Koreans watching their budget.
Korean superhero dramas often borrow the word 능력 (neungnyeok), literally 'capability,' as their casual shorthand for a superpower, avoiding grander Western terms. Laying out the rules of a power — triggers, side effects, range, recovery — in this practical, almost bureaucratic way reflects a very Korean storytelling tendency to treat extraordinary gifts as something to be managed and documented rather than celebrated.
