Nuestra hermana pequeña (2015)

In the coastal town of Kamakura, the Koda sisters--the twenty-nine-year-old, Sachi; the twenty-two-year-old, Yoshino, and the nineteen-year-old, Chika--live together in their late grandmother's ancestral house, since their father left them to live with another woman, and their mother followed soon afterwards. And then, unexpectedly--after so many years--the sisters receive news of their unfaithful father's demise, and much to their surprise, they meet their unknown but lively thirteen-year-old half-sister, Suzu, at his funeral. Straight away, the girls know that there are so many things that unite them, and as a result, it's only natural that Suzu joins them in the family house. Will the arrival of the little sister mark the beginning of a better future and a new purpose in life?
