It's possible that he associates heroine novels with a certain type of femininity that he doesn't identify with. He may feel that these novels are only for a particular audience, and as someone who doesn't fit into that audience, he hates them. Also, if he has a preference for male - centric stories or stories that are more gender - neutral, heroine novels would be far from his taste.
He might be a person who is more interested in complex plots and deep character development. Heroine novels, in his opinion, might be too simplistic, focusing mainly on the love story of the heroine and lacking in other areas such as political intrigue or moral dilemmas.
One reason could be that he thinks they are too unrealistic. Heroine novels often have elements of fantasy and over - the - top romance, which might not appeal to his more practical or down - to - earth nature.
One possible reason could be a misunderstanding. Maybe the hero misinterprets the heroine's actions or words and lashes out with an insult.
One possible reason could be a misunderstanding. Maybe there was some miscommunication in the past that led the hero to form a negative opinion of the heroine. For example, he might have overheard something that was misinterpreted.
Maybe he has some personal beliefs or values that conflict with the typical themes in heroine novels. For example, he might dislike the often overly romanticized or damsel - in - distress portrayals in those novels.
Maybe she has had some bad experiences related to so - called heroes in real life, which makes her cynical about the idealized heroes in romance novels.
Maybe she's scared of commitment or has trust issues. Or perhaps she feels like the hero is too intense or overwhelming for her.
One reason could be that some fans are very purist about the original Naruto story. They might feel that fanfiction often distorts the characters or the plot in ways that go against the essence of what Naruto is all about. For example, changing a character's personality completely to fit a romantic or dark and edgy narrative that doesn't align with the source material.
Perhaps the hero hides her out of jealousy or possessiveness. The result might be a lot of drama and misunderstandings before they finally work things out.
One possible reason could be that the hero has a bad reputation in the society they live in. Maybe he is known for being a playboy or having a cruel streak, which makes the heroine despise him.
Perhaps he thinks fanfic undermines the integrity of the original Naruto story. The official story has a certain narrative and character development, and fanfic can deviate from that significantly. When it comes to his connection with Naruto, any deviation in fanfic might be seen as a negative. For example, if a fanfic changes the way he mentors Naruto, it could be something he wouldn't like.
It might be due to cultural differences. Hermione comes from the wizarding world, and Annabeth from the demigod world. In fanfiction, these differences could be exaggerated, and Hermione might find Annabeth's 'alien' culture off - putting or difficult to understand, leading to dislike.
