In modern romance novels or fantasy novels, the male protagonist was usually younger than the female protagonist. This setting could attract the interest of young readers and add some romantic plot to the story. However, such a setting also had its limitations. If the storyline needed to show the wisdom and courage of the female protagonist or the various setbacks and growth experienced by the male protagonist in the process of growing up, then the setting of the female protagonist's age could also add depth and complexity to the story. Regardless of whether the male protagonist was young or the female protagonist was young, the plot and character settings required the author to cleverly conceive and portray them in order for the readers to truly feel the charm of the story.
