Tong Tong was expelled from her original school because of something, and was sent to the home of her brother-in-law, a teacher, to look after her. She was also allowed to attend school in the class taught by her brother-in-law. Tong Tong promised her mother that she would study hard and stop causing trouble. After she arrived in Class 3, Grade 2, she met many people, including the grumpy Fu Lina, the mean-spirited Liang Wei, the short cry-loving Hu Li, and many other interesting people. The stories of these people, as well as hers, made her the best memory of high school in a ridiculous way.
