Zhao Li and Song Xinyuan are half-brothers and sisters. Zhao Li's father and Song Xinyuan's mother are a recombined family. So they lived together naturally, but the reality was that the relationship between the reorganized family was not so harmonious.
The relationship between Zhao Li and Song Xinyuan was not so harmonious at the beginning. They teased, complained, fought, and later avoided and evaded, so that when they recalled it many years later, they still felt quite regretful.
