Well, a storyline could be that Naruto decides to leave the village. After seeing his parents die, he feels that there's no place for him there. He might go on a journey to find other jinchuriki and form an alliance with them, thinking that they are the only ones who can understand his pain. Another possibility is that Naruto becomes a vigilante. He doesn't trust the village's system anymore and takes matters into his own hands to protect the weak, which causes a rift between him and the village leaders. Also, he could befriend a powerful enemy who was also involved in his parents' death in some way, but through their relationship, he changes the enemy's view.
One possible storyline could be Naruto seeking revenge. Instead of focusing on becoming Hokage to gain recognition, he could be consumed by the need to find and punish those responsible for his parents' deaths. Another could be that he becomes more withdrawn and brooding, and it takes a special person or event to pull him out of his shell and back onto the path of a hero. Or perhaps he discovers some hidden power that his parents left for him to protect himself, which then sets him on a different journey of self - discovery.
One possible storyline could be that with his parents alive, Dark Naruto might not have turned so dark in the first place. His parents' love and guidance could have steered him away from the path of darkness. For example, Minato, being a powerful ninja, could have trained Naruto properly from a young age, and Kushina could have provided the emotional support he needed. This would change the whole dynamic of the Naruto universe as we know it, and there would be no need for him to seek power in dark ways.
A possible storyline is that Naruto starts to suspect that there was a darker reason for his parents leaving him. This could lead to a conflict within himself, whether to forgive them or not. He could also meet other orphans in the village and form a sort of support group. They could work together to change the village's perception of orphans. Another idea is that Naruto discovers a secret about his parents that puts him in danger, and he has to fight to protect that secret while also coming to terms with his feelings of abandonment.
One possible storyline could be that Naruto's parents, Minato and Kushina, are alive and they train Naruto from a young age. This would make Naruto an even more powerful ninja earlier on. He would grow up with their love and support, and perhaps not be as much of an outcast in the village as he was in the original story.
A possible plotline is that Naruto tries to hide the abuse from his friends and the village. He is afraid of being judged or rejected if they find out. However, as time goes on, the signs of abuse become more and more obvious. His friends start to suspect something is wrong and eventually, they discover the truth. This could lead to a series of events where Naruto's friends try to help him, and Naruto has to learn to trust them and accept their help to heal from the trauma of the abuse.
Well, he could start to explore the reasons behind his parents' neglect. Maybe he uncovers some dark family secrets that were the cause. This could lead him on a path of either revenge or forgiveness. He may also get involved in a conflict that has larger implications for the entire ninja world. And as he faces these challenges, he slowly transforms from a bitter, neglected child to a more self - aware and powerful individual.
One possible storyline could be that Naruto grows up with his parents' love and training. He might become an even more powerful ninja at a younger age. Since Minato was a prodigy and Kushina had strong chakra, they could pass on their skills and knowledge early. Naruto could also have a different personality, more confident and less of an outcast as he has a loving family from the start.
It could also be due to a prophecy. Suppose there's a prophecy that Naruto will bring great disaster in the future. His parents, believing in the prophecy, might decide to disown him in an attempt to avoid that future. They might think that by cutting ties with him, they can somehow change the course of events.
One possible reason could be the lack of presence of his parents. Growing up without them, he might feel abandoned. And as for Konoha, if he hates it, it could be due to the way he was treated as an outcast, despite being the son of important figures. Maybe the villagers' coldness towards him made him resent the village that didn't seem to protect him from that.
One possible storyline could be that Naruto's wife was killed during a major battle against a new and powerful enemy. This would send Naruto into a deep state of grief and depression, perhaps causing him to question his purpose as a shinobi. He might then embark on a journey to find the true cause of her death and seek revenge.
The Akatsuki is also a possibility. They are after jinchuriki, and if they knew about Naruto's existence as a baby, they might try to kidnap him early. They could think that by having him from the start, they can better control the Nine - Tailed Fox within him.
