[Childhood Sweethearts, Reunion After Years Apart, Mending a Broken Relationship, One-on-One Romance]

Mu Qingyao is the daughter of the wealthiest man in the land. For the sake of her family's interests, she abandoned her childhood sweetheart, the poor scholar Xiao Bieli, on the eve of their wedding. She married into a wealthy family, only to suffer a family tragedy and become a widow. She now runs the family business alone with her stepdaughter.

Five years later, her stepdaughter is kidnapped by the family's enemies. With nowhere else to turn, Mu Qingyao sends the long-sealed letter: "Xiao Bieli, please save her."

Three days later, her stepdaughter returns safe and sound, and the poor scholar she once knew has become the regent, The Outcast, second only to the emperor and above all others.

When he comes to ask for her hand, he says, "I won't take a principal wife. I'll marry into your family instead. Your household needs a steward, so I'll take the job."

The entire court is stunned: the regent wants to become the son-in-law of a merchant's daughter?
