One possible consequence could be a shift in the power dynamics within the village. With Naruto leaving, there might be a lack of his unique skills and leadership, which could lead to new challenges for Konoha in terms of defense against enemies. Another consequence could be the emotional impact on his friends and allies. They would likely feel betrayed or worried about his departure, and this could strain relationships. Also, Naruto's leaving might expose some hidden secrets or issues within Konoha's heritage that were previously overlooked, causing a stir within the village.
His decision could make him more self - reliant. Away from Konoha, Naruto has to depend solely on himself. He'll likely face new challenges that force him to dig deeper into his own abilities and beliefs. This could lead to a more mature and nuanced understanding of his own strength.
Maybe there are some dark secrets within Konoha that he discovers in the fanfic. These secrets could be related to the treatment of certain individuals or something more sinister about the village's leadership.

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.
