Seven-year-old Xiaomi is told by her mother to call her "Auntie" in front of other people. Even the cup she receives for her birthday is given away to another child. From that day on, she never calls her Mom again. Her father, who works away from home, quits his job and returns to the city to open a bakery, recording every pickup and every missed moment in a notebook. After her parents separate, the judge asks whom she wants to live with. She replies, "Mom is a name only I can call her." Later, Ye Qing, who works at the bakery, uses three meals a day and unfailing companionship to help Xiaomi say those two words again.
