This is a small time deep in Yu'er's memory, some are warm, some are touching, some are sad...
These are some of the people Yuer loves most and are destined to be bound to each other for a lifetime, friends, relatives, lovers...
These times and people constitute the world that Yuer can perceive.
Purpose: The proof that a person has been in this world is nothing more than the memory and a tombstone left in the mind of the deceased.
