Li Lao'er’s Ordinary Days

“The male lead has fragments of memories from more than ten years in the future.”

Except for a few major events,

many of the people in his memories only appear in them after he meets them in person.

The male lead changes other people’s fates one by one.

Later on, the male lead from World A will briefly communicate with the male lead from World B.

These are events in World B, so many things will be different.
