The relationship between Lin Tianjiao and Gao Xiang develops, as she begins to understand Gao Xiang better.

She then declines the award, and leaves the auditorium to rush to the train station to bid farewell to Gao Xiang. Unfortunately, she misses Gao Xiang. She (plus her brother, Lu Tiantian and Ou Xiaoyang) run into Gao Xiang's friends from the auto-ship, and hitch a ride to the local radio station, where Lin Tianjiao uses the programming to say farewell to Gao Xiang (singing The Beatles ' song "Hey Jude"). After a few years, Lin Tianjiao is a famous astronomer. She gave up on her mother's plan for her to study finance in Tsinghua University, but decided to follow her own dreams of doing astronomy.
