This is not a story about saving the world. It's a broken person who learns to love another broken being in an imperfect but real way.
Chen Liqiu is the third generation boss of Liqiu Hall. He suffers from dissociation disorder. He can accurately read the emotional value of other people's memories, but cannot sense his own emotions. His shop pawns memories, and "emotional interest" must be paid when redeeming them. When an old professor mortgaged the memory of his first love in 1957, Chen Liqiu accidentally triggered the system's awakening during the transaction and discovered that he might be the son of the creator of the memory system.
Concept: The value of memory is not in perfect preservation, but in real experience; the essence of love is not to be created or collected, but to choose to remember
