The Yi Ge Pawn Shop opened on a rainy night. If you pawn your memory, you can exchange it for a wish.
Some people pawn their first love in exchange for getting rich overnight, some people pawn their fear in exchange for fearlessness in life and death, and she pawns "everything about her father" in exchange for a chance to get him back from the depths of her memory.
She is Lin Wanqiu, the seventh-generation owner of Yige Pawnshop. Whoever touches her can see the memories that whomever wants to forget the most.
He is Lu Shiyan, a criminal investigation consultant who has lost all his memories before 1999. He is rational and restrained, but he only feels an inexplicable familiarity with her.
A series of "memory theft" cases tied them together - unsent love letters during the SARS period, encrypted MP3s in QQ online dating, Super Girl's collapse on stage... Every old time of the post-8090s is the key to an unsolved case.
They both forgot about each other, but fell in love with each other again during the pursuit.
When memories can be pawned, what are you willing to trade for the right not to be forgotten?
