길영 says this humble 국수 (guksu, noodle soup) restaurant has been his go-to since his rookie days on the force. In Korea, cheap local 국숫집 are comfort-food institutions — simple broth, hand-pulled or machine noodles, side kimchi — and regular customers often keep the same spot for decades. Choosing such a place over something fancy quietly tells us a lot about 길영's no-frills personality.
화평 explains that in her home village, demonic possession is called '손이 온다' — literally 'the hand comes.' It is a regional folk expression rather than standard Korean, pointing to the idea that something external reaches in and grabs hold of a person. Different communities in Korea have their own vernacular for what urban Koreans might call 귀신이 씌다 (being haunted or possessed).
한 신부 refers to himself as a 구마 사제 — an exorcist priest. The Catholic Church in Korea officially recognises exorcism (구마, 驅魔) under canon law, and each diocese may appoint a trained priest to perform it. The role is rare and kept quiet; drama series like this one draw on that genuine institutional secrecy to build atmosphere.
화평 teases her grandfather about his ancient television set still somehow working. Keeping a decades-old CRT TV is a recognisable shorthand in Korean dramas for an elderly rural household — grandparents in fishing or farming villages often hold onto appliances long past their expected lifespan, both out of frugality and habit. It's an affectionate generational joke Korean viewers immediately understand.
The neighbour drops by offering 노래미 — a small rockfish common along Korea's coasts — as a casual gift to drink with. Spontaneously sharing a fresh catch with neighbours is a deeply ingrained custom in Korean fishing communities; it doubles as a social visit and a reason to crack open makgeolli or soju together. The grandfather's slight embarrassment at having a guest shows how normal this impromptu hospitality is.
The orphanage director reveals that the young person they are discussing attempted suicide (자살 기도) while living there, underwent repeated hospital treatment, and was investigated by authorities as a result. In Korea, facilities housing minors have legal reporting obligations when a child self-harms, which explains the director's mention of investigations — and her strikingly callous framing of the incident as an inconvenience to herself.
화평 mutters about struggling to make 사납금 (sanapgeum), the fixed daily sum a taxi driver must hand over to the company before any of the remaining fares count as personal income. It is a pressure point well known to Korean viewers: drivers who fall short pay the difference out of pocket, so a slow shift or a long detour can mean working almost for nothing. The system has been widely criticised and is being phased out, but it remains common.
육광 is seen playing 화투 (hwatu), the Korean card game derived from the Japanese hanafuda. The cards feature flowers and plants matched to the twelve months, and 육광 hums about 흑싸리 — the black bush-clover card from August. 화투 is ubiquitous in Korean households and is strongly associated with leisurely or idle time-passing, perfectly suiting 육광's laid-back presence here.
육광 tells 화평 that her 귀문 (gwimun, 'ghost gate') is open, meaning her psychic threshold is low enough that spirits of all kinds can slip through freely. In Korean shamanistic belief, some people are born with or develop a permanently open spirit gate — usually those with innate 신기 (spiritual sensitivity) — making them both gifted and vulnerable. It is a sympathetic way of explaining why 화평 cannot stop seeing ghosts even when she wants to.
육광 arms himself with a branch from a peach tree grown pointing due east, explaining it will make evil spirits react when struck. In Korean and broader East Asian folk tradition, the peach tree (복숭아나무) is one of the most powerful natural wards against malevolent spirits; an east-facing branch is considered especially potent because east is the direction of rising yang energy. This is a genuine folk-magic detail, not something invented for the show.
윤 신부 uses the term 부마자 (浮魔者, bumaja), the Korean Catholic Church's formal word for a person who is demonically possessed and therefore a candidate for 구마 (exorcism). Using this precise ecclesiastical vocabulary signals that 윤 is approaching the situation from strict doctrinal method — checking for the classic physical sign of a reaction to a hidden cross — rather than accepting 화평's shamanistic interpretation.
