During an ordinary medical checkup, the doctor's remark, "Are you sure the child's father is biological?", plunges Shen Qiao into the abyss. In her husband's safe, she finds two paternity tests: one is Niannian, whom she raised, and the other is eight-month-old Lin Ke, who is also her biological child. Yet Shen Qiao only remembers giving birth to one daughter. While investigating, she discovers that after a car crash she forgot a full eleven months, forgot her first marriage to Gu Yanshen, and also forgot her eldest daughter Keke. Everyone has been hiding it from her, and she is the only one who does not know. Twelve years later, she finally sees Lin Ke, but chooses not to force the child to call her mom. As the truth is uncovered, how can maternal love and choice both be fulfilled?
