Our Little Sister

Three sisters, Sachi, Yoshino, and Chika, live together in their grandmother's house in Kamakura after their parents abandoned them. The oldest sister, Sachi, takes on a motherly role. When they learn of their father's death, they attend his funeral half-heartedly. However, during the funeral, they meet their 13-year-old half-sister Suzu and are captivated by her charm. Sachi invites Suzu to live with them, sensing that their father's widow, Yoko, would not be a suitable guardian.
