Li Fengsheng, a famous lady, and Xue Tao, the prince of the feudal lord, were childhood sweethearts and engaged to each other since childhood. However, a seemingly trivial incident involving a forehead flick stirred up years of resentment. In this unequal relationship, Li Fengsheng finally saw clearly that the other party's carelessness was related to her heart, and resolutely proposed to break off the engagement. After breaking off the engagement, she not only had to face Xue Tao's confusion and entanglement, and others' persuasion, but she also unexpectedly met Gu Xiangui, editor of the Hanlin Academy. In the process of breaking free from the emotional shackles of the past, Li Fengsheng gradually cleared away the fog, saw clearly the truth about people's hearts and the past, and also found his own direction in life in the process of self-awakening.
