Naruto could also be deeply hurt and go into a state of self - reflection. He might question his own judgment in relationships. For example, he could think about what he did wrong or if there were signs he missed. This could cause him to leave to find himself and grow stronger on his own. He may start to focus more on his ninja training and his friends in the village, trying to move on from the pain of being cheated on.
In such a fanfiction, Naruto might leave his village in anger and sadness. He could go on a journey of self - discovery, trying to come to terms with the betrayal. Maybe he'd meet new allies who help him grow stronger and more independent.
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.
His friends would be shocked at first. Sasuke might feel a sense of responsibility to find Naruto and bring him back. Sakura would probably feel guilty, especially if she was somehow involved in the situation that led to Naruto being cheated on.
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.
