When he was 16 years old, Yu Fan, a transfer student, met Wen Nannan. Wen Nannan was warm and generous, while Yu Fan was cold and sensitive. The two did not know each other without fighting. Yu Fan melted under Wen Nannan's warm face against her cold buttocks, and became friends with Jiang Lan and Yu Wenwen. The two even agreed to take the Jinling Nan University college entrance examination. On the day when the results came out, both Wen Nannan and Yu Fan had reached the score. However, something happened in Yu Fan's family and Yu Fan went abroad to study. Wen Nannan was heartbroken after being unable to contact Yu Fan, so she changed her choice to Nanjiang University. Ten years later, the two met again in a wine shop. At this time, Wen Nannan was calm, composed, and profound after entering the workplace, which was very different from before. On the contrary, Yu Fan changed his sunshine. In a car accident, the two returned to 10 years ago, when they were 17 years old. After Yu Fan explained everything, the two reconciled. And decided to make up for the regrets of the past and prevent tragedy from happening again.
