Designer Lu Qianqian is emotionally manipulated by her scumbag boyfriend and pressured into marriage. At her best friend's urging, she gets drunk at a KTV and impulsively marries her supposedly goofy distant cousin. When she wakes up, she discovers that she accidentally dragged his formidable older cousin, Xie Zhixing, a forensic doctor with severe germophobia, to register their marriage instead. Lu Qianqian panics and tries to run away, but the abstinent, powerful Xie Zhixing intercepts her. He offers her 5.2 million in spending money and his entire fortune, boldly declaring, "In the Xie family, there is only widowhood, never divorce!" Despite her ex-boyfriend's online harassment and her mother's coercion, the cold and aloof forensic doctor Xie Zhixing repeatedly protects Lu Qianqian, tearing apart every darkness threatening her and losing control of his self-restraint for her on countless nights.
