Y/N has a rap sheet longer than the school year; setting fires, starting fights, breaking rules just for the thrill of it. Expulsion? Suspension? Not a chance. Her parents' generous donations keep her untouchable, much to the staff's frustration. As a last resort, the principal assigns the student council to "babysit" her, keep her in check, tutor her, and, if possible, teach her how to be a functioning member of society. The council, made up of perfectionists and overachievers; Kim Minji, Pham Hanni, Lee Hyein, Danielle Marsh, Kang Haerin, thinks it'll be just another chore. But between detention study sessions, awkward after-school hangouts, and moments where trouble turns into laughter, the lines between captor and captive blur. What started as a punishment becomes something none of them expected; a messy, electric, and dangerously close bond that threatens to break every rule they've sworn to uphold.
