After Marrying in Her Father's Name, I Rule the Realm

Shen Zhiwei is the eldest legitimate daughter of the Prime Minister's mansion. As a child, her father brought back a concubine and a step-sister, causing her mother to miscarry and pass away. Since then, her affection has been stolen by her step-sister, Shen Zhiwan. The Emperor arranged a marriage for Shen Zhiwan with the Third Prince, Xiao Chengyu, rumored to be disabled and destined for a harsh border land. Her father forced her to marry in her sister's place. Initially reluctant, Shen Zhiwei later discovered that her beloved bodyguard, Xiao Yunzheng, is actually the Prince of Xue, who is obsessed with Shen Zhiwan and approaches her only for exploitation. After suffering repeated betrayals and injuries from him, she gave up hope and agreed to the distant marriage. On her departure, she blackmailed her father with 500,000 taels of gold, while Xiao Yunzheng, trying to please Shen Zhiwan, self-harmed and squandered his wealth, only to be played like a puppet. Unaware of this, Xiao Chengyu is actually the future heir chosen by the Emperor.
