Another reason could be in a fan - created scenario where there are secrets involved. Hinata might be keeping a secret from Naruto that, when revealed, makes Naruto feel betrayed or deceived. This sense of betrayal could easily turn into anger. For instance, if Hinata has a connection to an enemy that she's been hiding from Naruto.
Maybe in the fanfiction, Naruto has made some decisions that go against Hinata's beliefs or values. Suppose Naruto decides to use a very dangerous and unethical jutsu for power, and Hinata, who is usually very moral, might start to hate him for that.
Some people create such fanfiction maybe because they like to explore alternative or dark storylines. They might think it's interesting to deviate from the canon relationship between Naruto and Hinata.
It could be for the sake of creating an interesting and unique plot. Writers like to take characters out of their normal situations to explore different aspects of their personalities and relationships.
It could be due to jealousy. Some villagers might be jealous of Naruto's power and Hinata's noble status. So, they spread false rumors that lead to their banishment.
Stuttering is often used to show their nervousness. Naruto, who is usually confident, stuttering around Hinata can show his deeper feelings for her that he might not be fully aware of or know how to express. For Hinata, it emphasizes her shy nature.
Another reason is that in the original series, Naruto has a big dream and strong will. When he dominates in fanfiction, it's a continuation of that. Hinata, on the other hand, is often seen as someone who supports and admires Naruto. Fans like to see how Naruto's dominance plays out in different situations, whether it's in battles, relationships or village - related matters. This exploration of different aspects of their relationship through Naruto's dominance is what attracts many readers to such fanfiction.
In some fanfics, the idea of Naruto hating Hinata might be a plot device to create drama. Maybe the writer wants to explore a different kind of relationship dynamic than the canon one. It could also be that the writer has a unique interpretation of the characters' personalities and how they might clash in certain situations.
Well, Naruto has a unique charm in the Naruto world. He's a bit of an underdog who rises up. Hinata, being a more reserved character, is attracted to his boldness and his big dreams. In fanfiction, this is often exaggerated, making her 'crazy' about him. For example, she might see him as the only one who can truly understand her shyness and her own hidden strength, which makes her love for him grow to an extreme level.
Well, they're popular because it's a bit of a classic 'unrequited love finally fulfilled' story. Hinata has loved Naruto from afar for a long time, and fans like to see that love be reciprocated. It gives a sense of hope and satisfaction.
