Kimihiro is a high school student living a quiet life with his father. One day, his world is turned upside down when his favorite model, Sakiko, appears at his doorstep. Before he can process his confusion, his father reveals a shocking truth: Sakiko is actually his own sister. His parents divorced years ago, and Sakiko had been living with their mother. Now, she has come to live with them, forcing Kimihiro to navigate an unfamiliar family dynamic. As they share a home, he struggles with conflicting emotions, caught between the sister he never knew and the feelings that blur the lines of their new relationship.
