Su Jinning, the legitimate daughter of the Yongning Marquis Mansion, lost her mother when she was young and was treated harshly by her stepmother Liu Yuru. Her stepmother also arranged a marriage contract with her concubine Su Yuwei. At the wedding ceremony, she publicly exposed her stepmother's conspiracy to secretly change the engagement, and regained her own engagement with General Zhenbei. After that, she used her wits to fight against the unruly slaves, check the account books, seize the middle-class gifts, and remove her stepmother's minions one by one. When she met the concubine, she pretended to be pitiful to gain sympathy, so she exposed her hypocritical mask and let her suffer the consequences. Xiao Che, the general of Zhenbei, seems to be cold-faced and taciturn, but he only dotes on Su Jinning, shielding her from enemies and solving her difficulties. The two get to know each other in the house fights and intrigues. Su Jinning eventually became not only the legitimate daughter of the Hou family, but also the only wife in the General's heart.
