Born into the household of the Marquis of Le'an, she had no control over her own fate. The eldest young lady's husband, whom she hadn't even lifted her bridal veil to see, was suddenly exiled. Gu Xuan Nu had no choice but to take the young lady's place and set off into exile.
Rumor had it that her husband, Wei Changgeng's father, had taken away the Third Prince and raised him among the common people, where he suffered greatly. Wei Changgeng's father was already dead, but the emperor and the Third Prince still held a grudge against Wei Changgeng.
Everyone assumed Gu Xuan Nu would be utterly miserable with Wei Changgeng.
But Gu Xuan Nu knew nothing of all this. She believed that with her own two hands, she could build a good life.
And so, despite everyone's doubts, the two of them built a better and better life together. They became the wealthiest family in the place of exile, and Wei Changgeng even found a way to return to the capital.
Gu Xuan Nu thought their days would go on quietly and peacefully. She never expected that she was the true eldest daughter of the Marquis of Le'an's household, while the original eldest daughter was actually the one born into the household.
She thought being switched at birth was outrageous enough, but what was even more unbelievable was that Wei Changgeng was actually the real Third Prince!
