Lu Zehan&Luo Zhi
The two grew up together, but one day Lu Zehan suddenly went abroad without any news.
During that time, it happened to be a few days before the two were to get engaged, but he abandoned her and left without any reason.
It wasn't until many years later that Luo Zhi met Lu Zehan again in the restaurant.
At this time, Luo Zhi already regarded him as a stranger.
And she also decided to get engaged to someone else.
The biggest reason why Lu Zehan came back was to get her back.
