Zhou Yan, the prince of the Beijing Circle, is also a sought-after top student at Jinghua University. Wen Nuan has lived with her mother since she was a child. Her father committed suicide by jumping off a building because of debts, which caused a shadow in Xiao Wen Wen's heart. As a result, her mother also remarried a real estate owner. Her mother complained all day long and beat Wen Wen from time to time. She hid in her room and did not dare to speak out. Then she met Zhou Yan, who always encouraged her, warmed her, and brought her out of the shadows. Then the two met and fell in love with each other, but The beautiful days did not last long. Soon something happened to Nuan Nuan's family and her mother jumped off the building. This caused a lot of hurt and haze in Nuan Nuan's heart, and she suffered from depression. The day before the college entrance examination, Nuan Nuan reluctantly broke up with tears. Zhou Yan thought she was joking, but Nuan Nuan repeated: "Let's break up!" After saying that, Nuan Nuan ran away. Zhou Yan wanted to ask why, but he hadn't come yet. When he had time to ask, his eyes turned red. Wen Nuan didn't come to the exam the next day. Zhou Yan called and looked for it, but couldn't find it. The day after the exam, he found out that Wen Nuan had already taken a plane to go abroad. Five years later, Nuan Nuan returned to China and passed by Zhou Yan. They both wore sunglasses and seemed to not know each other. In the past five years, Zhou Yan established his own law firm, while Nuan Nuan took over while abroad. While receiving treatment, she was studying architectural design, until one day the two met in a restaurant. Zhou Yan seemed to be looking at a stranger again, took one look and left. Later, Zhou Yan called her while drunk at the bar and asked her why they broke up and why they left. Nuan Nuan remained silent. Zhou Yan said, "You are so cruel!"
