For sixteen-year-old Lin Zhenzhen, Qi Yu represented the first 'heartbeat'.
For twenty-six-year-old Lin Zhenzhen, Qi Yu represented complete "disheartenedness."
Lin Zhenzhen chased Qi Yu for ten years, and accompanied Qi Yu to wait for Bai Xinran for ten years.
When a wedding invitation with the names of Qi Yu and Bai Xinran was placed in front of her, Lin Zhenzhen realized that even after being hurt countless times, her heart still couldn't get used to it. But this time she was really tired and couldn't catch up anymore. So she chose to turn around and leave for the first time, but she didn't expect that this turn would take ten years and return to the starting point where everything started.
This time, she decided to love herself well, and said to Qi Yu when she was sixteen: Goodbye, never see you again.
