Yin Feng met 27-year-old Yang Wan in the summer when he was 25. At that time, Yang Wan's scumbag boyfriend was arguing with Yang Wan every day. In Yin Feng's eyes, Yang Wan was mature, gentle and careful, so Yin Feng gradually began to enter Yang Wan's life. After Yang Wan made the painful decision to break up with the scumbag, Yin Feng and Yang Wan came together. The two people have been stumbling in life for four years. Suddenly, Yang Wan's former colleague Chen Yu appears in Yang Wan's life. Because Yin Feng is very impatient, stubborn, and a little nervous, Yang Wan's life is miserable. The appearance of the mature and wealthy Chen Yu is undoubtedly a great test for the two people's lives. Can Yang Wan and Yin Feng finally go on?
