As a result of a family marriage, Lin Zhiwei and Shen Yan, who came from a scholarly family, had a flash marriage at the Civil Affairs Bureau. Underneath this marriage, which began as a contract, lies the old relationship and unspeakable thoughts of the two when they were young. The elders in the family are full of preferences, but the suitor disrupts the situation, others plot and frame them one after another, and many misunderstandings lie between the two. They not only have to fight against the conspiracy and persecution from the outside world, but also need to untie the knots that have been in their hearts for many years. After experiencing suspicion, danger, side by side, and overcoming old grievances, the two regretful people finally broke free from the shackles of fate and ushered in a stable two-way redemption.
