Maybe in the fanfic, Naruto has faced too many political intrigues within Konoha. He has always been loyal to the village, but if he constantly encounters backstabbing or unfair treatment from some of the village's leadership or clans, it could lead to his weariness.
A unique Naruto - inspired dessert in Konoha could be ramen - flavored ice cream in a fanfic. Picture this: the creamy ice cream with a hint of soy sauce, seaweed flakes, and a touch of spicy miso. It might be a new and trendy dessert created by a creative Konoha chef. It could be a big hit among the ninja kids who are always looking for something new and exciting to eat.
In a Konoha fanfic, Naruto desserts can serve as a form of comfort. For instance, when a character is feeling down, a warm bowl of anko - filled mochi might cheer them up. It's not just about the taste but also the memories associated with it. Maybe it was a dessert their mother used to make, so it has an emotional value.
I think it's a really bad idea. Naruto is a hero in the series, and the fourth Hokage is also a great character. Linking them in such a negative and inappropriate way is disrespectful to the story and the fans who love it.
One possible reason could be for Naruto's safety. Maybe she has to go on a dangerous mission and believes Konoha is the safest place for him. Another reason might be that she is forced by some powerful enemies who threaten Naruto's life if she doesn't leave him in Konoha.
Sakura would probably be very worried. She has always cared about Naruto deep down, so she might be constantly trying to find a way to bring him back. Kakashi, on the other hand, would likely understand Naruto's reasons to some extent. He might be sad but also respect Naruto's decision. As for Sasuke, if he is in the village at the time, he could be conflicted. He and Naruto have a complex relationship, and Naruto's leaving might make him realize how much Naruto actually means to him.
Maybe he marries an OC (original character). The author of the fanfic could create a whole new character with unique qualities that attract Naruto during his time away from Konoha.
It could be Orochimaru. He has always had his eyes on Konoha and might find a way to manipulate Naruto into attacking it. Maybe he uses some new experimental jutsu on Naruto to make him do his bidding.
