Legend has it that there is a soul pawnshop in the world that trades in family affection, fate, and lifespan. Once a contract is made, there is no turning back. Suffering from terminal stomach cancer, Lin Ting knocked on the door of the pawnshop to find her biological parents, only to learn that twenty years ago, to save their twin sister Lin Yu, her parents had pawned all of Lin Ting's family affection, fate, and entire life. From then on, Lin Ting was reduced to a tool, forced to donate her liver and subjected to endless torment. Seeing through the illusion of family affection, Lin Ting staked her remaining lifespan to redeem her fate, and after her life ended, she became an assistant at the soul pawnshop.
