Li Youyou and her business partner Ji Hanzhou signed a three-year agreement, each getting what they need without interfering with each other. She thought it was just a deal, but one day she accidentally found a photo from her college days in Ji Hanzhou's study - the profile of the girl in the photo was exactly the same as hers. Ji Hanzhou never called her by her name, only "Xiaojiu". Li Youyou gradually discovered that every unconscious move she made seemed to confirm a secret that she had long forgotten: she was not a substitute, she was the first love that Ji Hanzhou had been looking for for eight years. Amnesia Bai Yueguang went to the healing literature in both directions. The heroine lost her memory due to an accident, and the hero silently guarded her and waited for her to be awakened. The emotions are sincere and warm, focusing on the sense of fate of "I am destined to love you", which is in line with the public's view of marriage and love.
