Chen Shan is a female lawyer in the securities department of a famous law firm. She is nearly 40 years old and has encountered a bottleneck in her career. Therefore, she devotes herself to work and has no time to take care of the emotional needs of her husband and son. Her husband Sun Lei works in a state-owned enterprise. In order to support his wife's career, he has taken on the responsibility of taking care of the family and almost gave up his career pursuit. This marriage model of a strong woman and a weak man has gone from working well to gradually losing balance in the past decade, and has been overwhelmed unknowingly. At this time, investment bank elite Lin Qingkun appeared, and the big order in his hands became the target of competition between Chen Shan and her competitors. Faced with the dual crises of marriage and career, Chen Shan tried desperately to deal with both at the same time, but it was increasingly counterproductive. Sun Lei and Chen Shan have gone through many tests, and each of them has met a perfect partner who seems to be more suitable for them, but in the end they found that after stumbling for so long, their original intentions for each other are still there. As long as they cherish and support each other, they are the most perfect partners for each other.
