겉절이 (geotjeori) is a lightly seasoned, un-fermented kimchi eaten the day it's made — crunchy, bright, and less sour than aged kimchi. Bringing a big batch to someone's home is a classic Korean neighborly gesture, the kind a parent or in-law might do to check on a family member without making the visit feel like a formal intrusion.
누룽지 (nurungji) is the golden, slightly crispy layer of rice that sticks to the bottom of a stone or iron pot when rice is cooked the old-fashioned way. Many older Koreans grew up eating it as a snack or simmering it into a thin porridge. Preferring freshly pot-cooked rice with nurungji over a microwaveable packet (햇반, Hetbahn) is a subtle way of saying instant shortcuts feel hollow — and of asserting a certain old-school authority.
교권국 (Gyogwon-guk) translates roughly as the 'Education Rights Bureau' or 'Teacher Authority Bureau' — an invented government agency at the heart of this drama. The news segment framing it as a rising political force mirrors real Korean debates about 교권 (teacher authority), which became a major public issue after a wave of teacher suicides sparked nationwide protests in 2023.
Jang Wonyoung is a member of the K-pop group IVE and one of the most-referenced beauty standards among Korean teen girls right now — tall, slim, with large eyes and a bright smile. Casually dropping her name as a compliment ('you'd be a total Jang Wonyoung') is typical of how idol aesthetics set hyper-specific, body-conscious benchmarks in teenage social circles.
일진 (iljin) is Korean slang for a school-gang member or serial bully — kids who run informal hierarchies through fear and violence. The rumour that fellow inmate Kim Su-gyeom murdered every 일진 who tormented him turns him into an almost mythic figure among the delinquents, reflecting a real cultural undercurrent: when institutions fail victims repeatedly, fantasies of extreme self-help fill the vacuum.
