Lin Wanyi, the legitimate daughter of the Shangshu Mansion, was reborn thirty years ago. In her previous life, she and Xie Changhuai had been at odds with each other for thirty years, but only received his request before his death that she give up the life-saving opportunity to his concubine Lin Wanqing. In this life, Lin Wanyi fulfilled his wish and watched coldly as Xie Changhuai failed in the imperial examination and his official career was bleak without her support. Lin Wanqing also repeatedly acted like a monster and her reputation was ruined. Lin Wanyi unexpectedly received a marriage proposal from Gu Qingyuan, the general she had rescued, and the two got married. Xie Changhuai felt regretful after regaining his memories of his previous life, and even took risks to treason with the enemy, ultimately reaping the consequences. Lin Wanyi and Gu Qingyuan joined hands together, gave birth to an heir, and finally lived a happy life.
