Gossip about parents' deaths
0:51
Self-harm
The students are spreading rumours about a classmate whose parents both died by suicide. In Korean schools, this kind of whispered gossip travels fast through 엄마 네트워크 (mom networks) — parents sharing information in group chats — and children often repeat what they overhear at home without understanding the weight of it.

전국체전 (National Sports Festival)
1:05
전국체전, short for 전국체육대회, is South Korea's biggest multi-sport competition held every October, where athletes represent their home province or city. Winning three consecutive gold medals there as a school-age athlete is a serious achievement that puts you on the radar for the national Olympic programme.

스컬 / skeleton game character
1:52
The boy hands over a plastic skeleton figure calling it '스컬' (Skull) — a legendary loyal skeleton from a popular Korean mobile RPG. Giving away a prized in-game or toy collectible is a big deal for a kid; it's a genuine gesture of friendship, not just a random gift.

Police procedure at a student death scene
3:21
Self-harm
The detective announces the time of death and rules it a 자살 (suicide) on the spot, then asks for a quick wrap-up. In Korean schools, when a student dies on campus, there is enormous pressure from administrators to resolve the situation quietly and quickly to protect the school's reputation — a tension the drama is already leaning into.

App-based curse concept (주구)
10:49
The friends are debating whether a smartphone app can actually fulfil wishes and harm people. This taps into a long Korean folklore tradition of 저주 (cursed objects) that latch onto the living. The drama is updating that folk belief for the digital age — the idea that evil can spread through any medium that carries intent.
#
Trauma after parental loss
11:44
Seah describes recurring nightmares of her parents' disfigured bodies — a raw detail that explains why she reacts so fiercely to any new death around her. In Korea, children who lose parents suddenly and violently often have almost no formal grief counselling provided by the school system, which can leave that trauma entirely unprocessed.
#
고모 (paternal aunt) as guardian
14:08
Seah is living with her 고모, her father's sister. In Korean family structure, when both parents are gone it is common for an unmarried paternal aunt or uncle to take in the child rather than placing them in state care — keeping the child within the 부계 (patrilineal) family line is considered important for maintaining family honour.
#
Korean emergency call — 119
19:54
Seah calls 119, which is Korea's combined fire and medical emergency number (equivalent to 911 in the US or 999 in the UK). Police are reached separately on 112. That's why she asks for 경찰 (police) as a second request — callers sometimes have to explicitly ask for both services.
#
주구 — cursed object in Korean folk belief
24:56
하영 uses the term 주구 (呪具), a vessel that carries and transmits a curse. Traditional Korean 무속 (shamanic) belief holds that a curse isn't a free-floating thing — it needs a physical or symbolic container, like a letter, an image, or an object, to move from one person to another. The app fits neatly into this old framework.
#
Hospital resuscitation — 에이시스톨
26:23
The nurse calls out '에이시스톨' (asystole) — the flatline state where the heart shows no electrical activity at all. '에피네프린 투여' means they are injecting epinephrine (adrenaline) to try to restart it. Korean hospital dramas use the real clinical terminology that ER staff use, so these lines are accurate to actual procedure.
#
사주 (four pillars of destiny) in a wish ritual
27:14
The ritual instructions call for writing down your 생년월일 (birth date) and 사주 — the four pillars of birth year, month, day, and hour that define a person's fate in traditional Korean astrology. Including your 사주 in a spell or shamanistic ritual is meant to tie the working directly to your specific life-thread, making it far more powerful — and more dangerous.

Seah's selfless wish
29:23
Seah uses the app to wish for Geonu to be restored — accepting a countdown timer on herself to save him. This echoes the Korean concept of 희생 (self-sacrifice for those you love), which appears constantly in Korean storytelling from classical folk tales to modern dramas. The cultural expectation that a good person absorbs suffering so others don't have to gives this moment its full emotional weight.
