Bye, Mr. loser. You can watch the watermelon video. Introduction to the movie: At the wedding of Qiu Ya (Wang Zhi), the first love in school, after graduation, Charlotte (Shen Teng), who was raised by her wife, pretended to be a rich man and made a fool of herself. In the middle, her wife Ma Dongmei (Mary) stabbed her. In the chaos, Charlotte accidentally traveled through time and space and returned to the classroom of her student days in 1997. Ignorant, he thought it was a realistic dream, so he beat Mr. Wang, kissed him and tried to wake himself up by jumping off the building. When the injured man woke up from his hospital bed, he realized that he had really traveled through time and space. Since there is a chance to start over, it is better to have a good toss. He bravely pursued Qiu Ya, mocked Yuan Hua (Andrew), the top student, and refused Ma Dongmei's tenacious beating. Later, Charlotte entered the entertainment circle by composing famous songs for Pu Shu, Dou Wei and others. His life has changed greatly, but somewhere in his heart, he feels more and more empty.
