Wen and Ting became good friends when they were studying in a junior high school in Changsha. Up to now, although they had not lived in the same city for a long time, in Wen’s mind, Ting was still the only one who could be regarded as her best friend. They witnessed and spent the puberty of physical development and change, the first love of spring, the generation gap in communication with parents, and the weariness of learning before the entrance examination. In addition to going home to eat and sleep, they were basically inseparable. They were even teased by some naughty boys as having sexual orientation problems. At the end of the college entrance examination, Wen was admitted to a key university in Wuhan, and Ting’s score was only enough to read a college in Changsha. Although the two people were separated, their hearts never separated.
