Is your happiness a real experience or a memory uploaded by others?
Levi always thought he had a perfect life, until he had a recurring dream - a strange woman calling him silently in the rain. When he tried to pursue the truth, he found that the company that produced this "happiness" was trying to eliminate him at all costs. The only clue is the woman Lin Wei who is exactly the same as in the dream. She claims that she is his prototype, but she may be the trap itself.
Breaking into the restricted area of memory, he finally discovers the truth that is far more terrifying than the identity of the clone: he is not a life, but a computing unit that can be formatted at any time in the entire huge conspiracy... When memory becomes a commodity, truth is the most expensive luxury.
