A 폐차장 (pyecha-jang) is a vehicle scrapyard or junkyard. In Korean crime dramas and real life, these sprawling, semi-industrial lots on the outskirts of cities are often associated with shady dealings because they are hard to monitor — lots of hidden space, heavy machinery, and few passersby. The killer chose it as his base for exactly that reason.
South Korea requires virtually all able-bodied men to complete around 18–21 months of mandatory military service. Being granted an exemption (면제, myeonje) due to a psychiatric record is rare and carries social stigma — it flags someone as having a documented psychological condition serious enough for the military to turn them away, which the detectives treat as a significant red flag.
소년원 (sonyeonwon) is South Korea's juvenile correctional facility, roughly equivalent to a youth offender institution. Records from there are normally sealed once someone reaches adulthood, so the fact that the detective is able to pull this detail signals they are digging deep through official channels. Arson resulting in death at 15 would be treated as an extremely grave juvenile offence.
삼성각 (Samseong-gak) is a small shrine building found within many Korean Buddhist temple complexes. It enshrines three indigenous folk deities — the Mountain Spirit (산신), the Recluse (독성), and the Big Dipper deity (칠성) — absorbed from pre-Buddhist Korean shamanism. Seeing the gangster boss meditating inside one plays up the absurdist comedy of a criminal trying to go straight through spiritual retreat.
The news anchor mentions the play '푸른 수염과 7인의 신부' — a Korean adaptation of the Bluebeard fairy tale, in which a wealthy man secretly murders a series of wives and hides their bodies. The killer modelling his crimes on this story explains his compulsion to collect and hide women: he sees himself as the fairy-tale villain, which is a classic real-world pattern investigators call 'fantasy-driven offending.'
Local district offices (구청, gu-cheong) in Seoul regularly organise community charity bazaars and volunteer events, especially in autumn. Residents, local celebrities, and public figures are often invited as 위촉 (wichok) — officially appointed volunteers. The joke here is that Bong-ki's father was doing perfectly innocent cookie-decorating volunteer work, but his wife's jealousy made it look scandalous.
'천국의 계단' (Stairway to Heaven) is a hugely popular 2003 Korean melodrama famous for its emotionally exhausting plot and — literally — a long flight of stairs as a recurring dramatic image. The gangster grumbling that the temple steps feel like 'Stairway to Heaven' is a self-aware joke: the show was notorious for making viewers suffer, and he is suffering climbing the steps.
'별 헤는 밤' (Counting Stars at Night) is one of the most beloved poems in Korean literature, written by independence-era poet Yun Dong-ju in 1941. It is studied by virtually every Korean schoolchild. The gangster's parody version — counting stars like prison sentences ('4 priors left') — works as comedy precisely because every Korean in the room instantly recognises the solemn original.
추석 (Chuseok) is Korea's major autumn harvest festival, when families gather, hold ancestral rites (제사), and travel home. The monk-in-disguise saying he visited the bathhouse at Chuseok is a nod to the Korean tradition of taking a thorough bath or visiting a 사우나 (sauna/jjimjilbang) before big holidays as a form of ritual cleanliness and self-care.
