Han Qingyu, also known as Xu Muyao, the legitimate daughter of the Han family who was unjustly imprisoned in the past, the first thing she did when she returned to the imperial capital was to enter into a marriage contract with Ma Jiaqi, known as the "Devil of the Imperial Capital". A marriage letter connects the two people, it has nothing to do with love, each holds a bargaining chip, and uses the power in each other's hands to settle old grudges step by step and clear the way forward to hidden troubles.
