Y/n, a rich girl with a rebellious streak, transfers to HVIS's Section E-a class filled with delinquent boys. She has a rough time initally but refuses to be intimidated. The boys, especially Keifer, try to push her out with endless pranks and challenges. However, y/n is not an easy target-she outsmarts them, fights back, and slowly earns their respect. As the months pass, Keifer starts seeing her differently, and what began as rivalry and annoyance turns into something much deeper.
