On the other hand, Naruto could also be determined to prove his innocence or change their minds. He is a very persistent character. He might go on dangerous missions alone to show his worth and loyalty to the village and hope that Team 7 will see that he is still the same Naruto they once knew and liked.
Naruto might initially be very confused. He has always considered Team 7 as his friends, so the sudden hatred would be hard to understand. He could try to talk to them to find out what's wrong, but they might just ignore him or be hostile.
One possible reason could be misunderstandings. Naruto is a bit of an outcast at first, and his brash personality can be misinterpreted. In fanfiction, the team may misjudge his actions as being self - centered when in fact he's just trying to prove himself. This could lead to them hating him.
He could try to fight back against this hatred. Naruto has a strong will. Instead of just accepting being hated, he might try to prove everyone wrong. He could start by doing good deeds secretly or try to expose any false rumors that are causing people to hate him.
Naruto might also be determined to change his brother's mind. He would keep showing his good side, like his kindness and his strong will to protect the village. He could think that by being a better person, his brother will eventually stop hating him. He may even go through some tough training to prove himself not only to his brother but also to the whole village. And in the process, he may face a lot of difficulties and rejections from his brother, but he won't give up easily.
Sakura would be heartbroken. She'd likely spend hours upon hours by Naruto's side, trying to jog his memory with stories of their adventures together. She might even get a bit overbearing in her attempts. Sasuke, who has his own complex relationship with Naruto, would be conflicted. He'd see Naruto's forgetfulness as a sign of weakness at first but then realize the importance of their bond. Kakashi, being the experienced leader, would start by observing Naruto carefully to see exactly how much he has forgotten and then start a systematic process of helping him remember.
It could create a rift within the overall story's world. Fans who love Naruto might not like this portrayal, which could lead to a divide among the fan base. Also, other characters in the story might have to take sides, either with Naruto or with the team that hates him, causing more conflict and drama within the fanfiction.
At first, Naruto would be extremely hurt. He has always considered Team 7 as his family, so their betrayal would be a huge blow. He might go into a state of shock and disbelief.
Maybe in that fanfiction, Naruto's over - eagerness to be recognized could be misconstrued. His loud and boisterous nature might annoy people. For example, if he constantly interrupted others or pushed his ideas too hard without considering others' feelings, it could lead to dislike.
They would be shocked at first. Minato would be filled with pride and joy seeing his son all grown up. Kakashi would respect Naruto's strength. Obito might be a bit envious of Naruto's popularity but also admire his spirit. Rin would be very friendly towards Naruto.
At first, Naruto might be really confused. He's used to thinking of his friends as his support system, so when they turn on him, he doesn't understand why. He'll probably try to talk to them, to ask what he did wrong. If they don't listen, he could become really sad and withdrawn. Maybe he'll start training even harder, using the pain of being rejected by his friends as motivation to become stronger.
Naruto's reaction could be complex. He might be sad and disappointed, but he also has a lot of love in his heart. He could try to forgive his teammates, believing that there must be some misunderstanding. However, if they continue to oppose him, his reaction would turn more towards self - preservation and growth. He would focus on his own development, both as a ninja and as a person. He would use this betrayal as a motivation to become stronger, all while still hoping that one day he can reconcile with Team 7.
