Under the camphor tree in the city's No. 1 Middle School, transfer student Chen Yanqiu and "problem boy" Lu Shiyan became friends because they sat at the same table. He blocked her pranks, and she filled in his notes. There was a youthful love hidden in the strawberry milk and wrong question book. However, family changes and the pressure to enter higher education came like a storm, and she was forced to transfer to another school, leaving only a notebook with a picture of camphor. He waited all night for the graduation ceremony, and only exchanged pleasantries when they reunited after many years. This youthful love was both sweet and bitter, and in the end it became an unsent letter.
