After cremation at a Korean funeral home, the family collects the remaining bone fragments themselves — a ritual moment called 수골 (sugol). A staff member guides the family to gather the bones with special chopsticks before they are ground into ash and placed in an urn. It is one of the most intimate and painful duties a bereaved family performs.
육광 uses the phrase 인생무상 (insaengmusang), a Buddhist-flavored saying meaning 'life is fleeting and without substance.' Koreans reach for it in moments of loss to express that clinging to grief is useless because nothing in life is permanent. It is a common, somewhat philosophical way older men try — awkwardly — to console someone.
Korea has two broad types of shamans: 강신무 (gangshinmu), who receive their calling through a spirit possession crisis, and 세습무 (sesupmu), who inherit the role through family bloodline. 세습무 traditions are especially strong in the southern and southwestern regions. The elderly shaman 윤심 is being identified as someone from such a lineage, which explains why she was consulted for a ritual as serious as a 누름굿.
A 눌림굿 (nullimgut) is a shamanistic rite performed to press down or suppress a powerful spirit inside a person rather than expel it entirely. Think of it as placing a lid on a force too strong to remove. The show uses it to explain why 화평's supernatural senses were dormant for twenty years — the ritual was holding the entity in check, and now that hold is fading.
신기 (shingi) literally means 'spirit energy' or 'divine gift,' and refers to the innate sensitivity some people are believed to have that allows them to perceive ghosts and spirits. In Korean folk belief, this ability can be suppressed by a ritual but resurfaces when the suppression weakens. 육광's concern that 화평's 신기 is waking up again frames the supernatural events 화평 has been experiencing as something rooted inside him, not just around him.
박홍주 casually reminds the police chief that her late father used to dine at the same restaurant with him — a pointed reminder of the family's long reach into police circles. In Korea, 인맥 (inmak), personal networks built on shared history and loyalty, often carry more practical weight than formal authority. This is why a sitting assembly member (국회의원) can summon a police chief to a restaurant and expect results.
강길영 explains the concept of 부마자 (bumaja) to 봉상 — a person who has been entered and controlled by a malevolent spirit (악령). 빙의 (bingui) is the broader Korean term for spirit possession, familiar from folklore and still widely referenced in shamanistic contexts. In this drama the word 부마 is borrowed from Catholic exorcism language (from Chinese 附魔, 'attached demon'), blending religious traditions deliberately.
양 신부 identifies himself as being at 상용 동부 성당 — a local Catholic parish. Korea has a sizeable Catholic population (about 11 percent), and parishes are the community anchor for lay Catholics and priests alike. A priest being reachable at his parish at night is realistic; Korean priests typically live in the rectory attached to the church building.
양 신부 admits he deliberately hung a crucifix upside down to see how 화평 would react. In Catholic exorcism tradition, a person inhabited by a demonic presence is expected to recoil from or be physically harmed by sacred objects — holy water, a crucifix, a Bible. An inverted cross in this context is not the pop-culture 'Satanic' symbol but a controlled spiritual probe, the kind of test a trained exorcist might use.
Throughout the series, people controlled by 박일도 destroy their own eyes before dying. This is the drama's inversion of a Korean shamanistic belief that the eyes are the gateway through which spirits enter and exit a person. Destroying the eyes can signify either the spirit sealing its exit or erasing the evidence of possession — the show leaves the meaning deliberately ambiguous but roots it in this folk-belief framework.
화평 reads out an address in the form '화경리 90길' — the new Korean address system (도로명주소, road-name addressing), introduced nationally in 2014, names streets and then gives a building number. Before 2014, addresses used lot numbers (지번주소) which were famously difficult to navigate. The road-name system was meant to make emergency response faster, which makes it an ironic detail here.
봉상 speaks in a layered, eerie cadence characteristic of how this drama portrays 부마자 — the human host's voice mixed with something else, referencing events the host's ordinary self could not know. Korean possession narratives, both in shamanistic tradition and in horror fiction, consistently emphasize this bleed of the spirit's knowledge into the host's speech as proof that something else is now in control.
