Five years ago, Qiao Nian was schemed against by her sister, Qiao Xin. After spending a night with a stranger, Qiao Nian got pregnant. She did not know who the father of the child was, and eventually gave birth to a stillborn. Under the machinations of her mother and sister, Qiao Nian was stripped off of her shares in Qiao Group and sent to a mental hospital.

On the day he was born, the doctor predicted that he would not live past twenty years old. Her mother could not bear to see Qiao Xin marry such a person and thought of Qiao Nian, who was still locked in the mental hospital. Overnight, Qiao Nian was taken out of the hospital to replace Qiao Xin in her marriage into the Gu family. Her mother said, "It's a good thing that Qiao Nian, this good-for-nothing, can replace Xin'er to be a living widow in the Gu family. If Xin'er were to marry into that family, I would be heartbroken." Qiao Xin said, "Mom, don't say that about Sister. If it weren't for her, I wouldn't know what to do. I'm just worried that Sister wouldn't agree." Her father said, "Xin'er, you're too kind.

In the blink of an eye, her multiple identities shocked the world as each of them got exposed. It turned out that she was rich enough to rival a country! Later on, Second Young Master Gu placed a pair of Qiao Nian's miniature clones in front of her. Faced with these two children who resembled her and Gu Zhou, Qiao Nian blinked in shock. "When did I give birth to your children?"
