Sometimes being the villain is way more fun than being the hero.

Mamori Wataya is used to being a nobody. She lingers in the shadows of her high school, dismissed by everyone around her-that is, until she meets Soshi Fuji, the school's notorious troublemaker. Fueled by her deep admiration for villains, Mamori quickly becomes captivated by Fuji's devil-may-care attitude, and together they embark on a rebellion against the status quo.

Following a series of blushworthy mishaps, Fuji's feelings for Mamori deepen during an overnight study session at his house. When Fuji suddenly falls ill, Mamori attempts to nurse him back to health, only to discover she needs the help of her rival, Ichika. Can Mamori win over Ichika? Or will the young heiress remain an obstacle to Mamori and Fuji's budding romance?
