Five years ago, Sang Wu, a professional "liar", deliberately approached Huo Xichen, the flower of Qingcheng Gaoling, in order to raise money to save his grandmother. After he succeeded, he took the money and disappeared, which became a thorn in Huo Xichen's heart. Five years later, Sang Wu was hired by Huo Xichen's fiancée Ye Zhen. The task was to seduce Huo Xichen again to obtain evidence of cheating in order to break off the engagement. Sang Wu returned to Qingcheng and worked every step of the way, but found that he had already fallen into the trap set by Huo Xichen.
