On the wedding night, an accidental marriage swap occurred. Frontier warrior Lu Lingyue originally planned to give her dissolute husband a stern warning, only to find that the arrow was aimed at the cold-faced powerful minister Gu Xiting. Meanwhile, the gentle and reserved elder sister Lu Mingyue, who was supposed to marry into the Gu family and become the Second Councilor's wife, entered the bridal chamber of the dissolute scion Qin Mingchuan. Inside the deep courtyard, Lu Mingyue skillfully tamed the rake, turning a bad hand into a thriving success; outside the imperial court, Lu Lingyue drew her bow and rode her horse, living out the image of an independent heroine under the lifting support of her powerful minister husband. Everyone was waiting to make a joke of them, waiting and waiting, only to wait for the two most untouchable couples in the entire capital.
