Su Mingtang, the legitimate daughter of the Hou family, was raised in the lap of an old lady when her aunt died young. She thought she would be able to get married safely, but at the age of 18 she was involved in troubles in the house - harsh treatment by her stepmother, scheming by her concubine, conspiracy by sidemen, and she was even accused of marrying the rumored "cold-faced murderer" Dingbei General Pei Yan. Mingtang broke through the situation with wisdom. While dealing with the house fight, she and Pei Yan went from testing each other to connecting with each other. The couple worked together to resolve the crisis in the Marquis's mansion and the hidden dangers in the military camp. In the end, in the intertwining of the house and the country, they became each other's most solid support. They worked together to run the family and the government, writing a sweet story of marriage first and love later.
