In order to save the family business that was on the verge of bankruptcy, Yun Jinyu was forced to have a flash marriage with her ex-boyfriend Yan Zhongchen, whom she had decided to leave four years ago. After marriage, the two seem to have a cooperative relationship in which each gets what he wants, but as they get along again and again, they reopen old wounds and test each other's bottom line. Yan Zhongchen tried to make up for his past mistakes in a clumsy and persistent way, while Yun Jinyu hesitated between resistance and wavering.
When truth, misunderstandings and past disappointments intertwine, they must decide whether to drift apart in the shackles of the transaction, or to choose each other again in the process of learning to love again.
Concept: Under the dual pressure of reality and emotion, true love is not possession and control, but the mutual achievement of understanding, respect and self-growth.
