Lin Tianjiao (Guo Shutong) is a recognized three-good student in the eyes of classmates and teachers. Not only does she have excellent academic performance, but her moral character is also obvious to all. However, in a very important exam, Lin Tianjiao did not perform well because she caught a cold. She was anxious and thought of cheating, but she was exposed because of her poor cheating skills. Lin Tianjiao, who thought everything was over, did not expect that her classmate Gao Xiang (Bai Jingting) would take the blame for her. You know, Gao Xiang is the kind of troublemaker that Lin Tianjiao despises the most. He is lazy and idle and has nothing to do. In this way, a wonderful bond began to form between Lin Tianjiao and Gao Xiang. The more Lin Tianjiao wanted to stay away from Gao Xiang, the more a wonderful force brought the two together. As time went on, both of them gradually discovered the unknown soft side of each other's hearts.
