Another possibility could be a new character introduced in the fanfic. This new character might be using Naruto to gain something, like power or influence in the ninja world, and when they get what they want, they cheat on him. It would add an element of mystery and betrayal to the story.
If Naruto is cheated on in a fanfic, it has the potential to change the entire dynamic of the story. His friends might rally around him, which could strengthen their bonds. However, it could also drive a wedge between him and the person who cheated. His self - esteem could take a nosedive, and he might struggle to regain his confidence, both in himself and in the idea of love. This could lead to a darker, more brooding Naruto, which is a significant departure from his usually upbeat and determined self.
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.
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.
Yes, there are likely fanfictions out there with such a plot. Fanfic writers often explore different and sometimes controversial storylines. However, this goes against the strong bond between Sasuke and Naruto in the original series.
I think Naruto would be heartbroken. He's always been so open and sincere in his feelings. When he discovers Ino has cheated on him, he might go on a bit of a self - discovery journey. He'd wonder what he did wrong, even if it wasn't his fault at all. He could also become a bit more cynical about love, which would be a big change for him. He might start to see the world in a different light and be more guarded in future relationships.
In the long run, Naruto might try to find a way to redeem those who cheated on him. Despite the pain, his kind heart would still hope for the best. He would likely try to understand their motives and see if there's a way to fix the broken relationships, while also being more cautious and less trusting in the future.
He might also become more reserved in future relationships. After being cheated on by Anko, Naruto could be more cautious when it comes to getting close to someone again, always having that fear in the back of his mind that he could be betrayed once more.
Naruto might be initially shocked and heartbroken. He is someone who values loyalty and friendship deeply, so being cheated on would be a huge blow to him.
