The heroine Shen Ning and her husband Zhou Cheng were originally in love, but they accidentally miscarried after getting pregnant, resulting in infertility. Because of this, her husband Zhou Cheng began to neglect her, and later cheated on her with his subordinate Li Xin. After Shen Ning found out, she didn't expose it, but began to take revenge - she almost cuckolded her husband, two of whom were: the milk dog A (Lu Yuan) who liked her and the steady old classmate B (Lin Xiubo).
Zhou Cheng later came to his senses and discovered that Li Xin was just coveting his money, while Shen Ning was the one who truly loved him. He started frantically trying to win back Shen Ning and was very kind to her. Shen Ning accepted his kindness on the surface, but in fact she had already given up.
In the end, the two sat down and had a good chat. Shen Ning confessed that he had also cheated on her mentally. Zhou Cheng tried his best to stay, but Shen Ning believed that cheating once was unforgivable, and they eventually divorced.
