"Three Stations Subway"
Originally titled "Starlight Falls on the Third Floor of the High School"
In my senior year of high school, the top grader taught me 300 physics questions.
Later I found out that those 300 questions were considered good during the summer vacation of his sophomore year of high school.
Three days before I changed my mind, he had already paved all the way for me.
Three subway stops from Peking University to BIT.
He waited for me for a whole year.
