The elder brother had a grudge against the prince Gu Qing. In order to retaliate, he asked his younger sister Qin Ning to seduce the most cautious man in the capital and "dump him after the fun". Qin Ning was seduced by her beauty and agreed immediately. Unexpectedly, a series of ridiculous overtures resulted in the prince's vicious tongue and disgust. When she was publicly humiliated and embarrassed, Song Ci, her sweetheart who had been with her since childhood, silently guarded her time and time again. The farce ended, and Qin Ning finally understood that the person who taught her to write and protected her was her best friend in this life.
