The woman calling out to Yeon-jin is a 무당 (mudang), a Korean shaman. Shamanic rituals called 굿 (gut) are still practiced in Korea today and involve the mudang channeling spirits of the dead. Here the ritual setting makes Yeon-jin's guilt feel literal — the dead girl she wronged seems to appear right in front of her.
The shaman cries out '벌전' (beoljeon), meaning penalty or punishment money. In a 굿 ritual, when an angry spirit demands justice, the mudang may call for special spirit-money to appease or pay off the grievance. The shout signals that the ghost is demanding a price, not just acknowledgment.
친권 (chinkkwon) is the legal term for parental authority over a child in Korean family law. Losing 친권 in a divorce is a serious consequence — it means the court strips a parent of the right to make decisions for their child. The panic here shows how much Yeon-jin fears her public scandal costing her custody of Ye-sol.
Dong-eun borrowed the English phrase 'Have a nice day' as her personal sign-off when she first warned Yeon-jin's gang years ago in the school rooftop scene. Hearing it again now — delivered coldly in the video — signals to the bullies that whatever is happening is part of Dong-eun's long-planned revenge, not a coincidence.
Yeon-jin tells reporters that So-hee was pregnant when she died, framing this as a reason her death was ruled a suicide rather than a murder. In Korean news culture, revealing a deceased person's pregnancy is a calculated move to shift sympathy — implying mental distress — and to pre-empt a murder investigation. Dong-eun anticipated exactly this kind of deflection.
'콩깍지' literally means a peapod shell — the husk that covers beans before they're revealed. In everyday Korean, it describes being so infatuated with someone that you can't see their flaws, equivalent to 'having rose-colored glasses.' Sara mocking Hye-jeong with this word is a jab at how she still clings to Jae-jun despite everything.
The line about one who rejoices at another's suffering being like Satan echoes imagery from Proverbs and the Book of Job. Hye-jeong delivers it like a preacher pronouncing judgment — ironic given her own behavior. In Korean evangelical culture, citing scripture publicly to shame someone is a recognizable social move, especially among church-going families.
CC stands for country club, and in Korea membership signals elite status. The 그늘집 (geuneulljip) is literally the 'shade house' — a small refreshment stall on a golf course where players rest between holes. Jae-jun casually name-dropping that his club's 그늘집 makes great dumplings is peak Korean upper-class small talk, designed to establish who belongs.
안치실비 are the fees a hospital or morgue charges to keep an unclaimed or long-term body refrigerated. In Korea, families who cannot afford burial or who are waiting on legal proceedings can accumulate years of unpaid storage bills. The fact that So-hee's fees from 2004 have been outstanding all this time shows she had no one to look after her — until now.
696969 is the phone passcode Jae-jun casually reveals he already knew. In Korean slang, '69' carries the same sexual connotation as in English. Jae-jun blurting it out this casually — in a hospital room, to someone who can't talk back — is meant to show how little he regards other people even in a moment that should carry some gravity.
Yeong-cheon recounts that every hospital refused to treat him because he was a convicted killer. Yeo-jeong's father stepped in alone, insisting that judging guilt is the court's job and healing is the doctor's. This reflects a real ethical debate in Korean medicine and law — the Hippocratic obligation to treat even prisoners — and explains why Yeo-jeong now wants to follow his father into prison medicine.
In Korean family culture, 모성 (moseong) — maternal love — is treated as almost sacred, the idea that a mother will sacrifice anything for her child. Dong-eun's line pointedly inverts this: Yeon-jin's mother chose to protect herself by handing over the name-tag evidence. The betrayal lands so hard because it violates the deepest cultural expectation of what a Korean mother is supposed to be.
Yeo-jeong realizes that Dong-eun was listed as So-hee's mother's guardian on the hospital chart before the two of them ever reconnected on the train — meaning Dong-eun had mapped out every person in her plan years in advance. This kind of meticulous, years-long preparation is central to the drama's theme of 복수 (boksu), revenge as a life's work rather than a spontaneous act.
