Xiaohua is a clever, brilliant little genius. She lives a loving life with her mother, Gu Wan, who is shunned by her husband for being ugly. Her father keeps a mistress, Qiao Man, and her daughter, living a wealthy life while completely ignoring Xiaohua and her mother. After her mother's death, Xiaohua, dressed in mourning, crashes the wedding of her scumbag father and Qiao Man. In the scuffle, she hits her head and dies—but miraculously wakes up one year in the past! Reunited with her still-living mother, Xiaohua uses her genius intellect in this second life to save her mother from a deadly crisis and cure the face deemed ugly. She also exposes her father's betrayal, forces a divorce, and by her own power propels her mother to become the nation's first female billionaire.
