In his sophomore year of high school, Zhou Yanyan transferred to Jin An's class. When she and Du An gradually became fond of each other, her mother's words reminded her of the reason why she transferred from the "political and historical place" to the "material and chemical life" - to bring her grandma back from the suburbs in order to find a good job in the future. She began to distance herself from Duan, and Duan didn't know why, but he allowed the relationship to get further and further out of face, until he couldn't help but go find her during the Chinese New Year. So, they reconciled again. Zhou Yanyan originally thought that she would be able to clear up her relationship after going to college after the college entrance examination, but she found that conflicts gradually developed between them under the pressure of her senior year in high school. Then she heard the news that he was going abroad, which made her face the wealth gap between them. As a result, they lost contact after three years of college, until Zhou Yanyan accidentally went to intern at the driverless car company where Duan worked before graduation. Zhou Yanyan initially wanted to leave immediately after the six-month internship without having anything to do with him, but the reality is: Can Duan let her leave?
