High-end designer boutiques in Korea often require an appointment for fitting rooms, and walk-ins are politely turned away. Do Young bypassing that system — walking in without Yeon-jin and asking to try something on directly — is a quiet but deliberate power move that signals he owns the space.
Yeon-jin recites Hyeon-nam's daughter's full name, school, grade, and class number in one breath. In Korea, knowing someone's school registration details means you have pulled their official address record — it signals you have both the means and the will to reach their child. This is why Hyeon-nam collapses immediately.
Teachers at national and public schools in Korea are 공무원 (gongmuwon), full government civil servants with iron-clad job security and a pension. Mi-hui's immediate upgrade in attitude the moment she hears 'teacher' — then her disappointment that it's a private school — perfectly captures how much social weight that civil-servant status carries.
In Korea, a minor cannot withdraw from school without a parent or guardian's signature on a 자퇴서 (jatoeseo), a formal withdrawal document. Yeon-jin is reminding Dong-eun's mother that she was paid — by cheque last time — to sign that paper years ago, stripping Dong-eun of her education. It reframes their whole conversation as a repeat transaction.
The 동사무소 (dong-samuso), now officially called a 주민센터, is the local government office where residents register their address. Any citizen can request a 주민등록등본, a certified copy of someone's registered address, which is exactly how Mi-hui tracked Dong-eun down. It's a routine document used for banking and leases — but also, as shown here, for finding people who are hiding.
A '하우스' (hauseu) is Korean slang for an unlicensed private gambling den — think a back-room card or poker operation. The police chief is furious because his team raided one, exposing the corrupt arrangement he has with the people running it. These dens operate in a grey economy, often protected by paying off local cops.
잔치국수 (janchiguksu) are thin wheat noodles in a light anchovy broth, traditionally served at weddings and celebrations — hence 'banquet' noodles. Offering them to a frightened child she has just met is the retired teacher's way of saying 'you are safe here'; it is the Korean equivalent of making someone a warm bowl of soup.
When a family refuses to accept a coroner's ruling — especially a verdict of suicide — they can formally refuse to claim the body. Korean law allows a corpse to remain in a hospital morgue (안치실, anchisil) for an extended period while the dispute continues. Yoon So-hee's body has been there since 2004, a silent, physical protest against the official verdict.
The case filed in 2004 was officially closed as a suicide, but Yoon So-hee's family has refused to accept that conclusion and will not take her body. In Korea, disputing a 자살 (jasal) ruling is extremely difficult without new evidence, so refusing to claim the remains is one of the few ways a family can keep public pressure alive on an unresolved case.
프로포폴 (propofol) became notorious in Korea after several celebrity scandals in the 2010s revealed it was being administered casually in private clinics for cosmetic procedures and even for sleep. Its use outside of official surgical settings is heavily regulated, but the drama shows it still being offered here for a simple filler appointment — a detail Korean viewers read as a red flag immediately.
Myeong-oh claims to have physical proof — something kept inside an object he is holding — that places Yeon-jin on the rooftop the night Yoon So-hee died. In Korean criminal law, witness testimony alone is rarely enough to reopen a closed case; tangible evidence like a photo, recording, or physical item is what makes his threat real rather than just words.
Myeong-oh is offering Yeon-jin what he describes as a strawberry-scented substance in a small package, strongly implied to be a flavoured illegal drug. Flavoured or scented versions of drugs like philopon (methamphetamine) have appeared in Korean drug cases and in the press, making the detail recognisable to Korean viewers as a deliberate marker of his drug dealing.
Yeo-jeong administered propofol sedation before asking Yeon-jin about So-hee's death. Yeon-jin waking up to hear a voice she doesn't recognise — Do-young's, recorded or live — means she may have spoken while sedated. The episode ends on this note deliberately: in Korean legal terms, anything said under sedation is not admissible, but it could still destroy her.
