The heroine Su Wanxing was the "cute daughter" of the top wealthy Su family in Jiangcheng in her previous life. She was as innocent and sweet as a little white flower, but she mistakenly believed in the "adopted daughter" Lin Chuchu brought by her stepmother and her family's fiancé Gu Jinyan. The two men jointly planned the poisoning, thus taking away all the property of the Su family and killing Su's father and mother. When Su Wanxing was pushed off the cross-sea bridge and died with hatred, she saw Lin Chuchu wearing her wedding dress and embracing Gu Jinyan. Once reborn, she was taken back to the day of her 19th birthday party - the critical moment when Lin Chuchu debuted as an "adopted daughter" for the first time and when Gu Yanze proposed to her. After rebirth, Su Wanxing retained the memories of her previous life, but still had the ignorance and cowardice of Xiao Baihua. Facing familiar enemies, her instinctive fear made her subconsciously escape, but at the critical moment she said "I will not marry", shocking the entire audience.
