In September 2014, the middle school welcomed another batch of freshmen. Among these freshmen, a magical class appeared - 102. At first, Class 102 had a bad reputation. It was a bad class in the eyes of many teachers, with poor grades, poor discipline, and poor class cohesion. Later, when entering high school, Class 102 faced the fate of being divided into different classes. It was her appearance that saved Class 102. We affectionately called her "Geng Pangpang". After what happened, Class 102 began to fight back and became a legend in the school, making everyone start to look at it with admiration. "Goodbye, 102" reviews the three years of junior high school life from the perspective of a student in Class 102, recording the unforgettable memories on this campus. Please follow my words and find your youth.
