Who Says a Dandy Can't Marry a Princess?

A modern soul transmigrates into the capital's number-one wastrel and is chosen by Princess Zhaoyang to be her contract husband.

The two go from tearing apart the marriage contract, word by word, to joining forces to investigate cases.

Armed with account books as blades and evidence as swords, they crack down on illegal salt, uncover missing military funds, and expose exam corruption. A marriage first, love later, and a mutual devotion that draws them together.
