A 무당 (mudang) is a Korean shaman, usually a woman, who acts as a medium between the living and the spirit world. The role carries deep social stigma in modern South Korea — someone giving up a prestigious corporate job to become one would shock and embarrass most families, which is exactly why Ha-jun hid it.
Korean ride-hailing apps like Kakao T let drivers choose which trip requests — called 콜 (col, from 'call') — to accept. The driver's muttering means he regrets picking up a fare headed somewhere remote or difficult. Drivers can lose ratings or income on bad calls, so destination complaints under the breath are a familiar comedy beat in Korean dramas.
Ha-jun compares the mysterious gatekeeper to a 장승 (jangseung), a tall carved wooden or stone post traditionally placed at the entrance of villages and temples to ward off evil spirits. Calling a person a jangseung is a colourful way of saying they stand there like an immovable, expressionless guardian who won't let anyone pass.
처남 (cheonam) is the specific Korean term a man uses to address his wife's younger brother. Using it implies a marriage between Ha-jun's sister and Ha-jun — which is exactly why Ha-jun keeps objecting. Korean kinship titles carry relationship status the way a title deed carries ownership, so using one incorrectly (or cheekily) is a real social provocation.
Korean shamanic belief holds that a person's spirit is not a single thing but a set of parts — 넋 (neok) and 혼 (hon) refer to different aspects of the soul. Ha-yeong's ritual chant warns that a person cannot live if even one part goes missing, which sets up the logic of the whole rescue: Sae-a's soul-part has been captured and must be retrieved intact.
Ha-yeong calls on 문전신 (Munjeon-sin, the door god), 조왕신 (Jowang-sin, the kitchen/hearth god), 주목지신 and 정살지신, all traditional household guardian deities in Korean shamanism. Invoking them by name before entering a dangerous spiritual space is standard ritual practice — each deity is asked to protect a specific threshold or zone.
The rhythmic chant Ha-yeong sings is a 무가 (muga), a sacred song that shamans memorise over years of apprenticeship. This particular one names a series of spirit 'bridges' (다리) — pathways that help guide souls between the living world and the spirit world. The repetitive, incantatory style is meant to open those pathways.
The prohibition against looking back while passing through a spirit space echoes a widespread motif in Korean folk tales — looking back breaks the protective conditions set by a shaman or deity and exposes both the person and their guide to whatever is following. It is the spiritual equivalent of Orpheus and Eurydice, and audiences would recognise it immediately.
Ha-yeong breaks down the word 매흉: 묻을 매 (埋, to bury) + 흉악할 흉 (凶, evil/ominous) — literally 'a buried evil thing.' It refers to a physical object in which a curse is anchored, similar to the concept of a 저주 인형 (jeouju indyeong, cursed doll) or a buried charm used in folk hexes. Destroying it severs the spiritual connection.
Ha-yeong instructs Sae-a to dispose of her worn clothes in a designated spot so they can be burned. In Korean shamanic practice, garments that have been in contact with malevolent spirits or a spiritually polluted space are considered 부정 (bujeong, impure) and must be destroyed rather than washed — ordinary laundering would not remove the spiritual contamination.
Ha-yeong explains that the visions of Sae-a's deceased parents were not entirely fabricated — they were woven from Sae-a's own repressed grief, memories she had buried in her unconscious. Using a person's real love for the dead against them is a recognised motif in Korean ghost lore: the spirit (원령, wonryeong) exploits emotional bonds because they are the hardest to resist.
원령 (wonryeong) means the spirit of someone who died holding intense, unresolved resentment (한, han). Unlike a regular ghost, a wonryeong actively harms the living and can create curses that persist until the source of that resentment is addressed. Ha-yeong identifying the app as a wonryeong's curse frames the entire supernatural threat in traditional Korean spiritual terms.
