The cute illustrator Ruan Mianmian was signed into a stand-in agreement by Li Mingyuan in the name of "emotional healing" because his appearance was very similar to that of the male protagonist Li Mingyuan, the late Bai Yueguang. The heroine is gradually moved by the extreme tenderness and material compensation, but she is deeply trapped in the pain of being a "substitute" and the persecution of the vicious female partner. After going through trials, struggles, separations and career rises, she discovered that the so-called "White Moonlight" was actually a wife-chasing script tailor-made for her by the male protagonist. In the end, the script collapsed and her true heart was revealed, and she won her career and love with her true self.
