Mu Youxin thought that the summer of her senior year in high school would never happen again. When she was in her senior year of high school, she fell in love with Yu Zhouchu, a handsome boy who came to her rescue. The two got to know each other and became good friends. When she graduated, Mu Youxin plucked up the courage to confess her love but was politely rejected by Yu Zhouchu. All Mu Youxin's fantasies were shattered at that moment. Because Yu Zhouchu lied, the two of them were admitted to universities in two different cities. That summer was filled with the voices of Yu Zhouchu rejecting Mu Youxin. We were good friends. Mu Youxin did not go to the farewell party. Her family was not well-off and she chose to work part-time to earn money for traveling to Dalian. On her first day at the restaurant, she met a group of graduates who came to have fun and drank almost all the alcoholic products in the restaurant. Among them was a handsome boy who was taken home by Mu Youxin to take care of him because he could not contact his parents. So Mu Youxin and this boy named Yan Luo began an inexplicable fate.
