Tsubame attends Star's Hill Academy, a school divided into two sections: one for regular students and another for celebrities, known as the fine arts course or "celeb course." Stuck in the normal school, Tsubame has no interest in the upper-class life. However, she has been secretly eyeing Chio, a male model enrolled in the celeb course.

One day, while Tsubame is walking, Chio suddenly approaches her, grabs her, and announces to his fans, "Sorry, this is my girlfriend." Confused and dragged along, Tsubame finds herself forced into a "date" with the celebrity. Her ordinary school life is turned upside down as she gets entangled in Chio's world.
