In 2075, humans mastered the "memory retrospective" technology - through the implanted chip "Memory Mirror", memory fragments of specific objects can be projected into the consciousness of others, and the crime scene or character's experience can be restored.

Some people modify memories to cover up crimes, and some delete painful memories to escape reality...
When memories can be tampered with or even deleted, can humans still have a "self"?
