Description：Zheng Ruwei (played by Rainie Yang) and her boyfriend Tang Youyan (played by Yan Yulin) have been in love for many years, and their relationship is very stable. One day, Zheng Ruwei, a white-collar worker in the company, encountered a once-in-a-lifetime promotion opportunity. However, she had to go to Shanghai to work for this opportunity, which meant that she and Tang Youyan had to start a long-distance relationship full of unknowns and pain. Leave or stay, Zheng Ruwei doesn't know how to choose. The TV series uses parallel time and space to describe the possible ending that Zheng Ruwei might face after making a choice. After choosing to leave, although Zheng Ruwei was doing well in the workplace, the distance between her and Tang Youyan gradually drifted away, and eventually faced the ending of parting ways. After choosing to stay, Zheng Ruwei became pregnant and gave birth to a child, but gradually lost her light and became an ordinary and busy all-rounder.
