The Fu Family was an ancient and noble family, while the Shu Family was just an ordinarily wealthy household. Under normal circumstances, Shu Wan and Fu Siyu would never have crossed paths.
However, when Fu Siyu's birth mother was abducted and trying to escape, fortunately, she was rescued by Shu Wan's birth mother, which allowed her to survive until the rescue team arrived.
At that time, Shu Wan's birth mother already knew that her husband was keeping a mistress and had fathered two illegitimate children.
She was filled with indignation, but at that time, she was also suffering from a serious illness. Her parental family favored sons over daughters and would never help her look after her own children.
Thus, when Fu Siyu's father proposed to repay the kindness, Shu Wan's birth mother tentatively asked if a marriage could be arranged.
