Gu Xiying has been the darling of her family since she was a child. Her father runs a steel forging and processing company, and her family is wealthy. Xiang Bo is a poor boy from a small county town with no family background at all. One is a young lady and the other is a poor boy. When two people come together, the sparks of erasure are particularly eye-catching, especially in the intense study and life in high school. Along the way, they did not lose to teachers or parents, but they lost to their own self-esteem. When you are young, it is easy to regard self-esteem as a big deal, but you don't know that it is only for the strong. After the breakup, Gu Xiying went on a trip alone while Xiang Bo worked at home. While traveling, Gu Xiying met Xiang Bo's lost twin brother Chen Chaofan. Chen Chaofan fell in love with Gu Xiying at first sight and followed him all the way. Later the three met in college.
