Well, in some fanfictions, it might be because the writer wants to create an alternative storyline. Maybe they think Naruto has a different type of relationship in mind, like a more platonic or brother - sister - like bond with Hinata instead of a romantic one.
In some cases, the fanfiction might be taking a different approach to the characters' personalities. Naruto is a complex character, and in these fan - made stories, his dislike for Hinata could be due to a past event that changes his perception of her. For instance, if there was a misunderstanding between them in the past that led Naruto to form a negative opinion, and the fanfiction is about how they resolve this and eventually get together or not, depending on the direction of the story.
It could be that the fanfiction is exploring different character dynamics. Naruto might be portrayed as not liking Hinata in order to develop a plot where he has to overcome his initial feelings and grow to appreciate her in a different way. For example, the writer could be setting up a story where Naruto is so focused on his goals that he doesn't initially notice Hinata's feelings, and this is misinterpreted as dislike.
Maybe Naruto just sees Sakura as a friend. He might have a different idea of his ideal partner and Sakura doesn't fit that. His feelings for her could be purely platonic.
One possible reason could be his past traumas. Naruto grew up alone and was often shunned by the villagers. Physical touch might remind him of the times when he was pushed away or bullied, so he has developed an aversion to it in fanfiction.
Maybe in some fanfictions, the writer portrays Kakashi in a way that Naruto doesn't resonate with. For example, if Kakashi is written to be too strict or distant in a different way than in the original story, Naruto might not like that version of him.
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 possible reason could be miscommunication. Maybe Kakashi has been involved in some secret missions or decisions that Naruto doesn't understand, leading to a breakdown in trust. For example, if Kakashi made a call during a battle that put Naruto or his friends in danger without fully explaining it to Naruto later.
Well, some fans might create such fanfiction because they think Naruto's relationship with Sakura was more of a friendship. They feel that Naruto had a deeper bond with other characters like Sasuke in a different way than a romantic love for Sakura.
Maybe she likes it because she has deep feelings for Naruto and also respects Sasuke a great deal. Fanfictions allow her to explore different scenarios involving the two that she might have imagined in her mind.
Well, in some fanfictions, the author might want to create an alternate scenario where Harry has different relationship dynamics. Maybe they want to explore other pairings for Harry and so they write him as not liking Ginny to deviate from the original storyline.
It could be that she simply wants to keep her real relationship with Edward private. Fanfictions might make her feel like her relationship is being overly exposed or misrepresented. For example, some fanfictions might add in elements that she finds uncomfortable or not true to their actual connection.
Maybe in those fanfictions, the author portrays McGonagall in a way that Harry doesn't like. For example, the character might be out of character and act too harshly or differently from how he expects her to be in the original story.
