In the fast-paced city, 31-year-old Tao Xiangwan lives a sober and controlled life. The childhood trauma made her instinctively resist the opposite sex, and the marriages of her friends who were useless made her firm in her life choice of "not getting married". She devoted all her energy to work and only wanted a stable sense of security. 32-Year-old Yu Zhou has focused on his law firm career after his divorce and has dealt with countless marital disputes. He has long lost expectations for relationships and is used to the peace of being alone. A project docking led to the intersection of these two people who are equally cautious about relationships. The tacit understanding at work and companionship in life made them gradually let down their guard, but they were repeatedly pulled back by past experiences and interference from the outside world. This is an emotional record about urban men and women over 30 years old. It tells the story of how to break self-limitations and bravely embrace love under the influence of age anxiety, trauma and marriage prejudice.
