Kamura has been the caretaker of her family since her father's death in elementary school, handling household duties and ensuring her mother gets to work, as she vowed to protect her. When her mother announces plans to remarry, Kamura is introduced to her future stepfather and an older brother-in-law she had seen homeless the day before. Meanwhile, her friend Youhei, who often mocks her, begins acting unusually and even offers comfort. Kamura must now adjust to this new family dynamic, including a new father and brother, while learning to release the burden of being solely responsible for her mother.
