Zhou Xuanyi was admitted to the experimental middle school with the first score in the city, and his parents divorced on the day of the release of the list, and Zhou Xuanyi refused to live with either party. After entering high school, I closed my mind and didn't interact with anyone, and in addition to studying, I had to work on my own to make ends meet. In order to avoid the interference of other factors, Zhou Xuanyi chose to be a score-controlling scumbag, and his test results were just the passing line every time. Over time, everyone has forgotten about this former champion of the high school entrance examination. But the squad leader Tang Jing has been paying attention to this maverick teenager, from the curiosity at the beginning to the later understanding, she understands Zhou Xuanyi. At the graduation party, Zhou Xuanyi chose to confess to Tang Jing and entered Peking University together to start the next stage of life. Zhou Xuanyi, a sophomore, chose to start a business, and the days of entrepreneurship were very hard, but Tang Jing has always accompanied him and supported him without regrets. The two survived the start-up period together and got their first financing. After graduating from college, Zhou Xuanyi proposed to Tang Jing. Tang Jing said to Zhou Xuanyi: "I am willing to use the rest of my life to illuminate your world." A few years later, when Zhou Xuanyi recited Yeats's "When you are old" for Tang Jing by the sea, Tang Jing and Zhou Xuanyi hugged each other tightly, and they had no regrets in this life.
