Shen Weiwan, the owner behind the largest rouge shop in the capital, accidentally married Xie Jingxing, the current imperial master who was famous for his coldness and abstinence, in order to avoid being forced into marriage by his family.
On the wedding night, the two made a "non-interference" agreement. She thought the marriage was just a transaction where each got what he wanted - she used her status as the wife of the Taifu to protect the family business, while he used this marriage to block the whole family.
But after getting along, everything gradually went off track.
During the day, she was a dignified and decent wife, and at night she secretly went to the night market to sell rouge, and her abacus was crackling; on the surface, he was a serious official of the court, but he always "happened" to appear when she was being given trouble by the gangsters, silently giving her advice when she miscalculated her accounts, and when she giggled at the broken silver, there was a gentleness in her eyes that even she was not aware of.
When a little money lover meets Mr. Leng, when the account book encounters a memorial, the two people who originally had their own thoughts gradually turned the marriage agreement into honey through calculations and temptations.
"Xie Jingxing, you obviously don't like me showing up in public, why do you still help me calculate the cost of rouge?"
The tips of his ears were slightly red, and he threw over a copy of "Essential Techniques for Merchants" with a straight face: "... Lest you lose all your wealth and disgrace the Tutor's family."
It turns out that as cold as he is, he will also hide clumsy concern; as loving as she is, she will also wash her hands and make soup for him. This marriage, which began with an agreement, eventually became a tacit consummation.
