Our Little Sister 4K 2015

The father of the three daughters, Sachi, Yoshino and Tiki, left them for another woman when they were still children. Their mother, unable to bear their father's infidelity, also left them. Sachi's older sister was left with no choice but to become the head of the family and take care of the younger ones, even though she was still in high school at the time. After 14 years, their father dies, and the three sisters come to the funeral. There they meet their half-sister, 13-year-old Suzu. Suzu's mother has long since died, and after her father's death she is left with her stepmother and estranged brother. The sisters invite Suzu to come and live with them.
