일가견 means having a real expertise or strong opinion in something — like saying someone 'knows their stuff.' The joke here is that one character mangles the word, saying 일과견 or 과견 instead, and gets roasted for it. Misquoting set phrases is a classic source of comedy in Korean banter.
Dong-eun addresses Yeon-jin directly in her internal monologue, listing every person who participated in or witnessed her torment — not just the main bully, but anyone who walked beside her, laughed with her, or held her hand. In Korean revenge narratives this total accounting of accomplices is a moral framework: guilt extends outward like ripples, and so will the reckoning.
기일 (기일) is the anniversary of someone's death, and it's treated as a solemn family occasion in Korea. It's common for a hospital director's family to observe it privately; colleagues and staff often know the date out of respect for the family. The fact that a coworker has memorized it without being told signals how tight-knit — and gossip-prone — hospital culture can be.
Handing a father's watch to a child is a loaded gesture in Korean family culture — watches are associated with a patriarch's authority and the passage of that role to the next generation. It often appears at funerals or moments of transition, silently saying 'you carry this now.' The weight of the object is meant to feel heavier than it looks.
Korean schools are deeply stratified by parental wealth and connections (인맥, in-maek), and children's social standing often reflects their parents' status. Dong-eun's declaration that those three things — job, money, connections — will carry no power in her classroom is a radical statement in this context. It's a direct mirror of exactly what was weaponized against her when she was a student.
근정훈장 is a real South Korean state decoration awarded to civil servants, including educators, for distinguished public service. Ha Do-yeong's father having received one marks him as an officially honoured figure in the education system. Dong-eun weaponising this honour — threatening to tarnish it — is especially cutting because Korean society places enormous value on family reputation and public legacy.
Dong-eun describes her own moral journey in three precise Korean social roles: 방관자 (bystander), 피해자 (victim), and 가해자 (perpetrator/aggressor). These terms come directly from Korean anti-bullying education frameworks, which classify school violence participants in exactly these categories. Her deliberate use of the clinical vocabulary turns a personal confession into a structural indictment of the system.
Dong-eun compares Son Myeong-oh to an SD card she snapped in just to record what she needs. An SD card has no value on its own — it's a tool that stores what the user chooses. Framing a person this way is coldly transactional, and it shows how completely Dong-eun has reorganised her emotions around the chess logic of her revenge plan rather than personal feeling.
바둑 (baduk) — known internationally as Go — is an ancient board game of territory and encirclement played on a 19×19 grid. It's deeply woven into Korean culture, from neighbourhood 기원 (gi-won, baduk parlours) to professional tournaments. Dong-eun has learned it specifically as a framework for revenge: the goal is to surround and capture, not to attack head-on, which maps precisely onto her long-game strategy against Yeon-jin.
