Our Little Sister

There are three sisters: 29-year-old Sachi Kouda (Haruka Ayase), 22-year-old Yoshino Kouda (Masami Nagasawa) and 19-year-old Chika Kouda (Kaho). They live at a house in Kamakura, Japanese. Their house was left by their grandmother.

One day, they receive news of their father’s death. When the sisters were young, their parents divorced and their father left them. They haven’t seen their father in 15 years. Upon hearing the news on their father’s death, the sisters attend their father’s funeral.

At the funeral, they meet their stepsister Suzu Asano (Suzu Hirose). She is 14-years-old and there are no one to take care of her. Oldest sister Sachi invites Suzu to live with them.
