I Became the Prince's Favorite After Mistakenly Marrying into His Mansion

Song Muyu sponsored Li Jingwen for three years of high school, only for him to cheat with Bai Yanran and carefully plan a mistaken wedding, sending Song Muyu to the Northern Marcher Prince's mansion. She publicly settled old scores, smashed the Li family's new house, and tore up Li Jingwen's official credentials, giving a hard face-slapping to the unfaithful couple. The Northern Marcher Prince Qin Xiao, suffering from a 'madness' and facing his end, originally just wanted to enter a contract marriage to bring his mother out of the palace. However, through their interactions, he was healed by Song Muyu's intelligence, optimism, and Song parents' open-minded protection. After recovering, despite Empress Dowager and Bai Yanran's relentless schemes to frame him, Qin Xiao finally produced the late emperor's succession edict to calm the court turmoil, bringing Song Muyu to the throne.
