Wen Yitang, a jewelry designer, marries Fu Sinian, the president of the Fu Group. After their wedding, Fu Sinian's mother presents a forged infertility diagnosis and pressures her to divorce. Under his mother's pressure, Fu Sinian gives in and signs a divorce agreement stating, "There are no children born of this marriage during its existence." Forced to leave the Fu family with nothing, Wen Yitang is already pregnant with twins—a boy and a girl. Unwilling to use the children to win back her husband's affection, she leaves for Lanzhou City alone to protect her pregnancy and give birth. Before leaving, she secretly preserves Fu Sinian's biological samples, entrusts lawyer Lu Yan with securing the evidence, and establishes a private trust exclusively for her two children.
