Japanese drama "orange miracle"

The story is divided into two time and space. One is that ten years later, Xiang died, and Cai Sui was with Hiro who loved her and had a child. One is the present time and space. They changed history and Xiang survived. But it is precisely because of the relationship between the two time and space that the future time and space still continues the world without item, while item has survived in the present time and space.
