Ye Zhiyu, a merchant's daughter in the Great Sheng dynasty, learned the art of business from her maternal grandparents from an early age. Clever and decisive, she fell in love with Xiao Heng, the young heir of the Marquis of Ning'an, but their relationship was torn apart by their vastly different social standing. To inherit her family's business, Ye Zhiyu has no choice but to take in a live-in son-in-law. Yet she cannot find a suitable match until she meets Jiang Linfeng, a poor scholar.
Jiang Linfeng is impoverished but immensely talented. To repay Ye Zhiyu's kindness, he agrees to marry into her family, and the two enter into a marriage of convenience. He quietly learns the business, gradually winning over the Ye family with his sincerity and intelligence. They stand side by side in the perilous world of commerce, using honest business practices to break a corrupt merchant's monopoly, and feelings begin to blossom between them as they spend their days together.
When Xiao Heng unexpectedly returns and business rivals set a deadly trap, their marriage, founded on mutual gain, faces its greatest test. Can Ye Zhiyu and Jiang Linfeng stay true to themselves and weave a fine match through the tangled threads of political schemes and genuine affection?
