Rikuto Mitani had a new younger brother Ayumu after his father’s remarriage. However, little did he know that Ayumu was actually his younger sister and it was under her mother’s orders to pretend as a boy. Every day, his heart beats a little faster around his overly cute little sister, while her heart aches to conceal her real identity to her kind brother.

With the arrival of spring, Rikuto and Ayumu begin attending the popular private Asaoka Academy, with Ayumu enrolling as a girl. As he became friends with his classmates, he noticed that they all had something missing. His friend from middle school, Matsuri, has lost sight of what it meant to be a girl. The cool-mannered Mao dresses as a boy even though she is a girl. The extremely shy class rep Kimika wishes to change herself.
