Unemployed on a rainy night, Su Wanqing was hit by a tricycle, staining the mysterious antique scale with blood. "Bartering, no one can bully an old man." A voice sounded in his mind. From exchanging three days of life for a job to exchanging memories for skills, Su Wanqing has tasted the sweetness of equal exchange. She opened a firm and traded everything for people - beauty, talent, luck. Until she meets Gu Yan, the pianist who lost his musical talent due to her deal. When love grows, she realizes that all the gifts given by fate have been secretly marked with a price. What she wants to redeem is not only his talent, but also the entire world that has been disrupted by her own hands. This time, she had to pay the most expensive price.
Intent: This is a warning about how to keep human nature intact in the era of desire, and explores what is the bottom line of our lives when everything can be traded.
