In 2045, memories become a tradable commodity. People can rent out fragments of their own happiness, and they can also rent out an experience of being "deeply loved" to heal wounds and fill emptiness. "Echo", the world's largest memory company, declares: "There is no pain that cannot be cured." Lin Zhixia is the company's best "memory cleaner" - her job is to sneak into other people's minds, remove illegally implanted and remaining disordered memory fragments, and maintain the purity of the system.
Until one day, during a routine cleaning task, she accidentally came across a memory that did not belong to the client: a wedding in the sun, a man putting a ring on her and whispering in her ear: "Zhixia, I have been waiting for this day for a lifetime."
But she never married.
This memory was marked as "destroyed" and the source number was E-07 - a woman named Su Wanqing who died in a car accident seven years ago. Lin Zhixia's birthday, blood type, and childhood details closely overlapped with hers. She began to doubt: Are her memories really hers?
Whose replacement is she?
If my memories are not mine, then am I still alive?
Intention: The true self lies not in what you remember, but in who you choose to be.
