One common reaction could be Naruto's shock. In most fanfictions, Naruto is portrayed as someone who deeply loves Hinata, so being cheated on would leave him completely stunned.
Hinata might react with anger. She's a strong - willed character deep down. So she could confront the person who cheated on her head - on. She might yell and express her disappointment and hurt. This would show her growth from a shy girl to someone who stands up for herself.
One common plot twist could be that Hinata finds out she was actually set up. Maybe someone was jealous of her relationship and made it look like her partner cheated. This would add a layer of mystery and give Hinata a chance to fight for her relationship.
It could be that the fanfiction author has a different view on the characters. They might not be satisfied with the original relationship development in the Naruto series. So they come up with the idea of Hinata cheating on Naruto to show an alternative scenario. For example, they could be trying to show how Naruto would deal with betrayal, which is a very different aspect from the original story where Naruto is mainly about his growth as a ninja and his positive relationships.
In fanfiction where Spiderman gets cheated on, it often explores the emotional turmoil he goes through. It can be a way to add more depth to his character. Writers might show his vulnerability and how he copes with the betrayal. Maybe he throws himself more into his superhero duties to distract from the pain.
Well, in the realm of fanfiction, anything can be written, but it has no basis in the official Naruto storyline. Naruto is portrayed as a loyal character, and his relationship with Hinata is based on deep love and respect. So, the 'naruto cheated on hinata' in fanfiction is just a wild, unfounded idea that some fanfic writers like to explore for the sake of creating conflict in their stories.
One possible outcome in this fanfiction could be Percy feeling a deep sense of betrayal. He might initially be in denial, not wanting to believe that he has been cheated on. This could lead to a downward spiral in his self - esteem as he questions what he did wrong in the relationship.
There could be many interpretations in such a fanfiction. Maybe it shows Naruto's vulnerability in relationships. It might be a way to explore his character deeper by putting him in a difficult emotional situation.
Ino could be a very complex character in this fanfiction. It's possible that she cheats on Naruto because she has a fear of commitment. Naruto is a very passionate and all - in kind of person, and that might scare Ino. So, to avoid getting too deep into the relationship, she cheats. Or perhaps there's a power struggle at play. She might think that being with a different person would give her more influence or status in the ninja world. And there could be a hidden agenda that she's following, something that she can't achieve with Naruto but believes she can with someone else.
