Chen Mo pawned the memory of his deceased girlfriend just to escape the pain. After the transaction, he began to dream of strange fragments: the platform on a rainy day, the ring that was not given away, and the medical records hidden in the drawer. He pawned not only the pain, but also his girlfriend's last distress signal before she died. In order to regain his complete memory, Chen Mo became a temporary clerk in a pawn shop, helping the mysterious shop owner Lin Wan deal with all kinds of customers - some people pawned the warmth of their childhood in exchange for a promotion, and some people pawned their first love to get rid of their obsessions. He discovered that Lin Wan had pawned the "memory of being loved" in exchange for eternal life guarding the pawn shop, forever losing the feeling of love and being loved. In the end, Chen Mo faced a choice: retrieve his memory and face the pain to fulfill his promise, or help Lin Wan redeem his memory and make the pawn shop disappear?
