The story begins in the student union office of Yanqing University with a discussion about the welcome party. Lu Jing, a sophomore in the Department of Physics and President of the Student Union, and Qin Wanyao, a sophomore in the Department of Mathematics, Vice Chairman of the Student Union and President of the Music Club, are arguing over the details. However, underneath the seemingly business-like conversation, there was an unspoken intimacy and understanding between the two - they were childhood sweethearts who had been together since childhood, and they confirmed their relationship after the college entrance examination. In the eyes of others, they are the proud sons of heaven: Lu Jing is the second son of the Lu Group, and his brother Lu Mo is the established heir. He is smart and calm, and is a popular figure on campus; Qin Wanyao is the second princess of the Qin Group, and her sister Qin Zhen is in charge of the family business. She is bright, dazzling, and talented. But to each other, the other is just the "one" who grew up together and shared all their secrets and dreams.
