Mary Sue novels were based on traditional fairy tales such as Cinderella and Snow White, creating an extremely romantic, beautiful, and unrealistic love story. In these novels, the female protagonist usually had extraordinary beauty, wisdom, martial arts, and wealth, while the male protagonist was usually a perfect character who loved the female protagonist unconditionally without any flaws. The word "Mary Sue" came from the novel "Carrie the Witch" by Kelly of the Soviet Union. It was later borrowed by some novelists as a fictional literary style that was popular in Asia. It is worth noting that although Mary Sue novels are usually considered romantic fantasies, in fact, many of the plots in Mary Sue novels are impossible in reality. These novels often attracted readers with fake romance and unrealistic plots, but at the same time, they also reflected some of the expectations and fantasies of contemporary young people towards love and ideals.
