우원재 (Woo Won-jae) is a real South Korean rapper and singer who rose to fame after appearing on the hit survival show 'Show Me the Money 6' in 2017. Attending a solo concert without telling your parents is a big deal for a kid Hajun's age — Korean idol and artist concerts sell out instantly and feel like once-in-a-lifetime events to fans.
Suhyeok shows Yuyeon a small card that just says '웃어' (smile / laugh). Giving someone a tiny handwritten note or printed card with a single encouraging word is a common way young Koreans express quiet emotional support — it is more personal than a text message but less burdensome than a long talk.
Jiyong orders Hajun to roll up his trouser leg — the classic set-up for striking a child's calf with a hand or a rod, called 종아리를 맞다. This was a widely practiced form of parental and school discipline in Korea for generations. Attitudes have shifted significantly and it is now legally considered abuse, but older cultural scripts around it persist in dramas set in wealthy, traditional households.
Heesu tells Hajun '오늘은 그냥 자자, 내일은 오늘이랑 다를 거야' — essentially 'let's just sleep tonight; tomorrow will be different.' Telling a child to sleep through pain rather than talk it out right away reflects a Korean tendency to let emotions settle overnight before addressing them, rooted in the idea that exhaustion makes everything harder to process.
Soonhye mutters '거지발싸개 같은 놈들,' literally 'guys like a beggar's foot-rag.' A foot-rag (발싸개) was a strip of cloth peasants wrapped around their feet instead of socks — so this insult equates the tabloid journalists to the lowest, most wretched thing imaginable. It is a very old-fashioned and vivid piece of Korean invective.
The appraiser identifies the blue diamond as a '라자르 컷' — a Lazare cut, referring to Lazare Kaplan International, a New York diamond house famous for its precise ideal-cut stones. Each Lazare diamond is laser-inscribed with a unique serial number, which is what makes it instantly traceable. This is why selling it anywhere would immediately flag it as stolen.
Jinhee mentions '서래마을 취선당,' placing Heebin's restaurant in Seorae Village (서래마을), a neighbourhood in Seoul's Seocho district historically associated with the French expat community and upscale dining. Dropping a Seorae Village address signals that Heebin's establishment — and by extension her world — is expensive, refined, and firmly in the upper-class orbit.
Jiyong tells Seohyeon he knows her future partners would be women, not men — implicitly outing her as a lesbian. In conservative Korean chaebol society, same-sex relationships carry enormous stigma; a woman in Seohyeon's position would be expected to maintain a conventional marriage entirely for appearances. This is why she married into the Han family and why the secret has been so carefully kept.
When the nun asks what that person meant to Seohyeon, she answers simply '마인 — 내 거요' ('mine — they were mine'). This single word is the title of the entire series. In Korean, saying '내 거' (my thing / mine) about a person is intensely possessive and intimate — it collapses the polite distance Koreans usually maintain and lays bare how completely Seohyeon has privately claimed this relationship.
Jiyong tells Hajun that people who are 'not born ordinary' have something taken from them by God in exchange — a way of making elite privilege sound like sacrifice. This kind of fatalistic framing is common in how wealthy Korean families explain hardship to children, softening the truth with a philosophy that positions loss as the price of greatness rather than the consequence of adult choices.
Hajun tells Heesu he wishes he could go back in time and be inside her womb — to have been hers from the very beginning. This is an extraordinarily raw expression of longing for unconditional belonging. In Korean culture, the bond between mother and child is often described as starting before birth (태교, prenatal care and bonding is taken very seriously), so his wish to share that origin with her is deeply meaningful.
Seohyeon uses the phrase '불편한 진실' (an uncomfortable truth) — also echoed in the episode's title — when she finally comes to tell Heesu about Jageyong. The nun earlier turned the same phrase back at her as a question: would you choose uncomfortable truth or false peace (거짓된 평화)? The episode has been building to this moment as Seohyeon's answer.
