In my mind, the ending must be HE. Regardless of whether Cheng Fengtai waited for Shang Xirui at the station in the end, Shang Xirui went. No matter if he misses the train, as long as Shang Xirui is willing, he can find Cheng Fengtai in every corner of the world, let alone Hong Kong.
After watching the TV series, I decided that he was a HE, but I still couldn't get over it. I like them both so much. So I just wanted to write an article casually, just to be honest.
The setting of this article is that the previous life was BE, and Cheng Fengtai did not wait for Shang Xirui. After that separation, they never saw each other again, becoming each other's lifelong concern and regret.
Intention: true love
