Adapted from the original novel "Dear Sponsor, Please Respect Yourself" by the author Tao Guan, the story is about Ye Xiaotang, a wealthy girl who lost her dream-making crystal and had to find a husband before the age of 20 to prolong her life. She was determined to marry the cold scholar Mu Jinyan as her husband, but she fell in love with him after all the twists and turns. She even ignored the prince Ling Ziran who took the initiative to pursue her. An unsolved case entangled the fate of the three people together. On the one hand, they were happy to play: the "unfavored" prince was despised for his persistence, and the rich girl pursued the arrogant and cold-faced man under the pretext of assisting in the investigation; on the other hand, fate was embarrassing: the cold heart was finally resolved, but because of their natural incompatibility, the lovers could not stay together in the end; how should the three face the challenges given by fate?
