Jiang Xu, a memory reconstruction specialist, is accused of stealing a man's memories, only to discover that the person who was truly forgotten is herself.
Jiang Xu is the youngest licensed memory reconstruction specialist in the country.
Eight years on the job, with no accidents. She has erased pain from countless people and never made a mistake.
Until Fu Yanzheng comes to her door.
He thrusts a surgical record at her. Her name is in the signature field. He says she stole a memory from his mind three years ago and demands that she give it back.
Jiang Xu searches through every medical record but finds no trace of the procedure. She concludes he's got the wrong person.
But her body doesn't agree.
There's a scar on the ring finger of his left hand. She doesn't know where it came from, but every time she sees it, her heartbeat slows.
There's a ring on her right hand. She's worn it for three years and never asked where it came from.
There's an encrypted album on her phone called "Do Not Open."
That night, she opens it. There's only one photo inside: her hand clasped with the scarred hand, their fingers intertwined.
She doesn't remember taking the photo.
But the ring on her hand in the picture is still on her finger now.
