Even as a little girl, Bai Ziyan never believed that fate was decided by heaven. She was strong and resilient. Faced with her relatives' cruelty and her mother's death, she refused to give up. She and her sisters lived together with the kindhearted older brother, Fu Tingkai. Later, Fu Tingkai arranged for the sisters to study and grow in different places. Little by little, Bai Ziyan fell in love with him. As an adult, Bai Ziyan became independent, capable, astute, and perceptive at work. Step by step, she sought justice for her mother from her relatives. Though her younger sister resented her, Bai Ziyan never stopped cherishing their family bond.
After Fu Tingkai went missing, he returned, but it wasn't him. It was his twin brother, Fu Xiuyan, who shared the same mother but had a different father. Decades into their life together, Bai Ziyan discovered this earth-shattering secret, and could only weep helplessly. When she saw the Fu Tingkai of old again, everything had changed. He had become her brother-in-law.
