In a blink of an eye, Yizhen (played by Tianxin) and her husband Shao Wen (played by Li Mingshun) have been married for seven years. During these seven years, Yizhen has always played the role of a good wife and completed her job perfectly and impeccably, but as time went on, Yizhen found that she and Shao Wen had fewer and fewer common topics, and finally there was only suffocating silence between the two. Yizhen felt that in her long marriage life, she might have taken a wrong step, which led to her current situation. At the moment when she was most hesitant and entangled, a man named Zhou Shangen (played by Qiu Kaiwei) appeared beside Yizhen. Shangen's existence made Yizhen regain her passion for life. Although neither of them was free, they could not suppress the throbbing in their hearts and had an unethical relationship.
