During her time in junior high school, Mao Manaka gives off the impression of a poised and elegant young lady. However, her impulsive nature becomes apparent when she becomes fixated on something. This trait causes her classmates to keep their distance - a behavior that her childhood friend, Ryouma, compares to that of a bulldozer. Despite this, Ryouma enjoys being the only one who can stay by her side, as he harbors feelings for Mao.
Their relationship undergoes a shift when Mao meets Hayato Honjou, a budding actor who is struggling to establish himself in the entertainment world. Ryouma can see that Mao becomes increasingly fascinated with Hayato's promising career. Eventually, Mao reveals to Ryouma that her heart is smitten with Hayato, and she is determined to get closer to him.
