Pei Ji was a transfer student. After transferring to No. 7 Middle School, he became roommates with Xia Huaixing. Xia Huaixing is generally cheerful, but not very good at studies, while Pei Ji is a relatively aloof scholar who doesn't like to talk because of his family background. It was Xia Huaixing who redeemed him and allowed him to step out of the shadow of his original family. He also helped Xia Huaixing make progress so that he was no longer a thorn in the teacher's side. But the good times did not last long. Pei Ji transferred to another school and moved to Chongqing. Xia Huaixing waited for him for three full years, and three years later the two met again.
