It could be that Naruto starts to question the values and leadership in Konoha. He has seen a lot and perhaps he realizes that some things need to change. He might start a movement within the village to make things better or he could choose to distance himself from those who uphold the old, perhaps flawed, ways.
Maybe Naruto decides to leave Konoha for a while in the fanfiction. He might feel that the village has let him down in some ways and needs to find himself outside of it.
In this fanfiction, Naruto may have reached his breaking point with Konoha due to various reasons. It could be the constant political intrigue, the way some of the villagers still treat him despite his heroics, or his disillusionment with the shinobi system in general. He could then set out on a journey to find a new place where he can be true to himself and his ideals, or he could try to reform Konoha from the inside out in a more radical way than ever before.
One reason could be that the fanfiction might have misrepresented Naruto's character. He's a complex character with strong values, and if the fanfiction twisted those, he'd have enough. For example, if it made him out to be too subservient to Konoha when he's always fought for change within the village.
Well, Naruto might leave Konoha because of the political unrest within the village. He may feel that his ideals are not being supported by the current leadership. For example, if they are more focused on power and control rather than the well - being of everyone. And perhaps he's just tired of the never - ending cycle of conflict that always seems to involve Konoha, and he wants to find his own path away from it all.
Perhaps he would journey to the Hidden Cloud Village. There he could meet new people and learn different techniques. He might also try to bridge the gap between Konoha and the Cloud Village, starting from outside Konoha's boundaries. This would be a way for him to still work towards peace on a larger scale, but away from the restrictions he felt in Konoha.
Well, Naruto might first confide in his closest friends like Sasuke or Sakura. They could either support his decision to break away from Konoha's norm or try to convince him to stay. If he leaves, he could encounter new enemies or allies in different lands. His skills and reputation would precede him, but he would be a sort of outcast from his own village.
In such a fanfiction, Naruto leaving Konoha could lead to his daughter having a different upbringing. She might be raised in a more secluded place, away from the hustle and bustle of the village. As a result, she could have a more independent personality. And she would probably have to face the challenges of not having the full support of the village that Naruto once had. But with Naruto as her father, she'd surely be strong - willed and determined to make her mark in the ninja world.
Perhaps Naruto has grown weary of the excessive focus on Sakura in fanfiction. He might feel that other aspects of his life and the world around him are being overlooked. His own growth, his relationships with other characters like Sasuke, or his dreams for the village are not given as much attention as they should be in these fan - created stories. So, he's had enough.
In this fanfiction, the Naruto family might be welcomed back with great joy. The villagers could hold a big celebration to honor their return. Naruto, as a hero, would finally be home with his family in Konoha, and his kids might start exploring the village that their father has so many memories of.
One possibility is that Naruto is being captured for a misunderstanding. Maybe Konoha has received false information about Naruto being a threat. In the fanfiction, this could lead to his friends having to prove his innocence.
In my opinion, 'naruto has had enough fanfiction' may mean that the Naruto series has been subject to an overabundance of fan - made fictional works. Fanfiction can be great, but when there are too many, it can start to feel like the original Naruto concept is being drowned out. There could also be a sense that the creativity in fanfiction has become repetitive or is going in directions that don't really fit with the core of Naruto.
In such a fanfiction, they might leave Konoha to start a new life in a peaceful place. Maybe they are tired of the shinobi life full of battles and politics in Konoha. They could find a small village by the sea and build a simple house there, living a quiet life away from the chaos.
