Leanne, a commoner who received a scholarship to the prestigious noble school, was mistaken for the princess because of her pale blue hair. She exploited this resemblance, pretending to be the princess, bullying others, and enjoying free money and privileges. Since the real princess didn't attend the school, Leanne, now a second-year student, continued her deception. Today, the new noble first-years arrived, including the real princess, who Leanne didn't recognize.

They bumped into each other in the hall; both had pale blue hair, but different eyes. The empire's princess, Astrid Arianne Valious, is the identity Leanne used to her advantage. As the princess hadn't made her debut, no one had seen her face.
