It could be because fans like to explore different relationship dynamics. The idea of Naruto, who is usually seen as a hero, having this flaw of neglecting someone like Fem Sasuke adds an interesting layer to their relationship.
Well, in the original Naruto story, Sasuke and Naruto have a complex relationship. By creating Fem Sasuke and the concept of neglect, fanfiction writers can explore themes of unrequited love, friendship gone wrong, and the pain of being overlooked. It also gives a chance to rewrite parts of the story from a different perspective. For example, how Fem Sasuke might feel and react differently compared to the male Sasuke in the face of Naruto's neglect.
There's a fanfiction called 'Silent Longing'. In this story, Fem Sasuke has feelings for Naruto but he is too busy chasing after power and recognition in the ninja world to pay attention to her. It shows how she copes with this neglect and her own growth in the process. Another one could be 'Abandoned Promises' which delves into how Fem Sasuke's expectations from Naruto are not met as he neglects her in their relationship.
Another reason could be to deviate from the original story's narrative. In the original, they have a lot of attention in different ways. By making them neglected, it creates a whole new set of plot possibilities. For example, they might form different alliances or develop new skills out of necessity.
It could also be to add more depth to their relationship. When they are neglected, they have to rely on each other more. For example, in a fanfiction where the village turns their backs on them, Naruto and Sasuke might form an even stronger bond as they face this together. This gives writers a chance to develop their friendship in new and interesting ways. Also, it can be a way to introduce new plotlines and conflicts that wouldn't exist in the original story. By changing their status from being in the center of attention to being neglected, new challenges and opportunities for character growth are created.
One example could be a story where Naruto is so focused on becoming Hokage that he unintentionally neglects fem Sasuke. She might start to feel left out and lonely. In such a fanfiction, the author could explore her feelings of abandonment and how she tries to get Naruto's attention back.
Well, it could involve Naruto being overlooked or ignored by the village in this fanfic. And his relationship with Fem Sasuke could start as a form of mutual understanding. Maybe they find solace in each other because of their own issues. For example, Naruto's loneliness due to being neglected and Fem Sasuke's own complex past.
In fanfiction, the idea of Naruto banishing Fem Sasuke might be used to create drama. It's a way to put a new spin on the relationship between the two characters.
Maybe Naruto sees Sasuke as a strong and unique male character. Changing Sasuke into a female in fanfiction might go against his perception of their relationship and Sasuke's true identity. It could also be that he feels it's disrespectful to Sasuke's character development as a male ninja.
The concept is fascinating as it allows for exploring different aspects of their personalities. Naruto's neglected state can bring out a more vulnerable side, while fem Itachi can show a more nurturing or empathetic side. This contrast can create a lot of drama and tension in the fanfiction. Also, it gives a chance to rewrite the relationships in the Naruto world in a new and exciting way. It can make readers see the characters from a fresh perspective and imagine different futures for them.
The neglect can create a lot of distance. For example, fem Sasuke might start to close herself off emotionally. She may feel that Naruto doesn't value her as much as she thought. This could lead to her being more cold and distant towards him.
In canon, Naruto is not completely neglected in the long run and Sasuke is male. In this fanfiction, Naruto being neglected for a long time would change his character development. And having Fem Sasuke instead of male Sasuke completely changes the dynamic of their relationship.
