Perhaps Naruto is focused on his own personal growth and training. He might see the yaoi relationships around him as a distraction from his goals of becoming a stronger ninja. He could be thinking that engaging with others involved in yaoi would lead him astray from his path of self - improvement.
It may add tension to the story. If Naruto is a key character and he's not interacting, it can disrupt the normal flow of relationships in the fanfiction. This disruption can cause conflict among other characters who rely on Naruto for various reasons, like teamwork in ninja missions.
Well, there could be various reasons. Maybe the writer wants to create a unique situation where Naruto is silent to add mystery. For example, if the fanfiction is set in a scenario where Naruto has lost his voice due to a curse or some kind of magic. It could also be that the author is focusing on other characters' reactions to Naruto's silence, which can bring out different aspects of their personalities.
As Naruto is silent, his friends might start to recall past events to see if there were any signs leading up to this. They could also try different ways to communicate with him without words, like using body language or leaving him notes. This could lead to some interesting interactions and new friendships or alliances forming as they all work together to reach Naruto.
Perhaps he's under a powerful genjutsu. In the Naruto universe, genjutsu can manipulate a person's perception and behavior. It's possible that an enemy has cast a genjutsu on Naruto that makes him believe that if he talks to anyone, something bad will happen to them, so he chooses to remain silent.
One possible reason could be a traumatic event. Maybe he witnessed something so horrible that it made him shut himself off from everyone. For example, if he saw his friends in great danger and couldn't save them in time, it might have led to his silence as a form of self - blame.
The plot could develop through the reactions of other characters. They would be confused and concerned about Naruto's silence, which could lead to them trying different ways to reach out to him. For instance, Sakura might use her medical ninjutsu to check if there's any physical reason for his silence.
One impact is that it can change the dynamic between Naruto and other characters. Since he's not talking, other characters might have to take on more of a communicative role. For example, Sasuke might have to be more perceptive of Naruto's non - verbal cues, which could lead to a different kind of relationship development between them.
In some fanfictions, the author might make fem Naruto not talk to create an air of mystery around her character. By not speaking, she becomes more of an enigma, which can draw readers in. It could also be related to her character development. For example, she may be shy or introverted at the start of the story and gradually learn to open up and speak as she grows and overcomes her insecurities.
Well, it could be that the fanfiction is set in a very different universe where Naruto has different upbringing or experiences. But this is quite a stretch because Naruto's caring side is so deeply rooted in his story. It might also be that the writer is simply trying to create shock value by presenting such a counter - intuitive view of Naruto. But in general, it's not in line with the essence of Naruto as we know him from the original series, and it might be a bit of a gimmick to make the fanfiction stand out in a sea of more traditional Naruto stories.
