Mao Manaka is a 15-year-old junior high school student who presents herself as a refined beauty, yet she is actually an impulsive girl who becomes extremely persistent once she sets her mind on something—a trait her childhood friend Ryouma compares to a bulldozer. This personality tends to keep peers her age at a distance, while Ryouma appreciates being essentially the only one who can spend time with her, as he secretly harbors feelings for Mao. Ryouma's daily routine with Mao shifts when she encounters Hayato Honjou, a novice actor struggling to establish himself in the entertainment industry. Ryouma quickly observes a change in Mao's attitude as she begins showing significant interest in Hayato's rising career. Mao soon confesses to Ryouma that she has feelings for Hayato and demonstrates her resolve to get closer to him.
