One possible reason could be a misunderstanding. Maybe there was some miscommunication in the past that led Naruto to believe his family didn't understand him. For example, if his family had different expectations for his future as a ninja compared to his own dreams.
Well, it changes the family dynamic significantly. In the original story, family is a very important theme, especially later when Naruto discovers his connection to his parents. In this fanfiction, the lack of communication with his family means Naruto may not have the same support system, which could lead to a different path in his ninja journey.
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.
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.
One plotline could be Naruto's journey to find out the truth about his family. He doesn't care about them initially, but as he uncovers secrets, his feelings start to change. Maybe he discovers that they had a noble reason for their actions that he misinterpreted.
One possible reason could be that in the fanfiction, his family might have been portrayed as overly strict or controlling. Maybe they forced him into a certain path he didn't want to take, like a particular ninja training regime that Naruto found too rigid.
One possible reason could be a misdirection in his goals. If in the fanfiction he is overly focused on proving himself to the village, he might think that family is a distraction. So, he starts to distance himself from his family to concentrate more on getting recognition from the village.
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.
One possible reason could be that his newfound 'godlike' powers make his family feel estranged. They might not understand his sudden transformation and the magnitude of his power, which creates a sense of fear or discomfort, leading them to ignore him.
One possible reason could be that the fanfiction portrays his family in a way that goes against his ideals. For example, if his family is depicted as being involved in immoral or unethical activities, Naruto, with his strong sense of justice, would have a hard time accepting them.
