Shen Ruojin died unjustly in her previous life and was reborn on her wedding day, forced to face the humiliation of her intended, Pei Jing, eloping with her half-sister all over again. She decisively chooses Qin Lang as her husband, intending to divorce him a year later. But as they spend time together, Qin Lang turns over a new leaf and supports her wholeheartedly. Yet the trauma of her previous life leaves Shen Ruojin suspicious of him.
Meanwhile, villains from all sides, driven by jealousy and self-interest, keep sabotaging her life and tarnishing her family’s reputation. In this chaotic age, Shen Ruojin faces the many restrictions society places on women. She must take revenge before the villains can fully secure their power, all while struggling to choose between vengeance and protecting the man she loves. In the end, Shen Ruojin and Qin Lang join forces to break through their predicament: one guards the nation’s borders with a gun, the other wields power to steady the court. But behind their victory lie the many hardships endured by their family and the one they love.
