Aimi, a shy and determined student, is preparing for the Miss Campus contest, where she faces fierce competition from the elegant and refined Shiraishi-san. Aimi's secret, however, is anything but refined—she's a neet who's been living a reclusive life, hiding the truth from everyone, even her friends. Her only confidant is her older brother, affectionately called "Oniichan," who constantly teases and plays pranks on her, making her both embarrassed and excited.
As the day of the contest approaches, Aimi finds herself in a series of awkward and intimate situations with her brother, who seems to know all her secrets. Their interactions are a mix of playful teasing, seductive moments, and unexpected revelations. Aimi’s brother, though seemingly childish, has a deep affection for her, and his constant encouragement helps her build the confidence she needs to face her rival, Shiraishi-san, and the rest of the competition.
In a series of increasingly bold and intimate encounters, Aimi's insecurities are challenged, and her relationship with her brother grows more intense. Each moment brings her closer to her goal, as she begins to embrace her true self, shedding the layers of her reclusive life and stepping into the spotlight with newfound courage.
As the contest begins, Aimi faces not only her rival but also her own fears and desires. Her journey is not just about winning the title of Miss Campus—it's about discovering her strength, embracing her identity, and finally letting go of the shame that has held her back for so long. With the support of her brother and the memories of their intimate moments, Aimi is ready to shine, no matter what comes next.
