When sycamore leaves fell all over the playground of Xinghua Middle School, Lin Xiaoxing walked into Class 3, Grade 2 (Grade 3) with a washed white schoolbag on her back. She was known as the "lower child" in the school. She always hovered around the passing line in math exams. Her new classmate, Gu Yanze, was the academic god who always ranked first in the grade. He even easily won the long-distance running championship in the sports meeting.
