Their relationship would go through several stages. Initially, there would be a sense of unease as they are leaving their home. However, as they journey on, they will encounter various difficulties. For example, when they are short on food and supplies, they have to work together to find resources. This kind of shared experience would make them more empathetic towards each other. Sasuke, who has always been reserved, might open up more about his family and his quest for revenge in a more sincere way to Naruto. Naruto, in turn, would share his insecurities about being the Jinchuriki. Over time, their relationship would evolve from comrades to true friends who are willing to sacrifice for each other.
At the beginning, their relationship might be a bit rocky. Sasuke is used to being alone, and Sakura has to adjust to his way of doing things. However, as they face challenges together, like fighting off enemy ninjas or surviving in harsh environments, they start to bond. Sakura's constant support and her growth as a ninja start to make Sasuke respect her more. Eventually, this respect could lead to a more intimate relationship where they truly open up to each other.
On the other hand, their relationships could grow stronger. Away from the rules and expectations of Konoha, they rely more on each other. Naruto and Sasuke could finally understand each other better. Sakura, with her medical skills, becomes even more important to them. They start to trust each other more deeply, and their bond as a team becomes unbreakable. They might have heart - to - heart conversations that they never had in Konoha.
At first, their relationship might be a bit rocky. They both have strong personalities and different ways of doing things. But as they face challenges together, they start to understand and respect each other more. Their bond grows stronger as they rely on each other for survival.
One possible plot could be that they leave Konoha due to a new threat that the village is unable or unwilling to face. They might go on a journey to find a way to defeat this threat on their own. Along the way, they could face many challenges that test their friendship and skills.
One possible plot twist could be that they are being secretly manipulated by an unknown enemy who wants them out of Konoha for some dark purpose. Maybe this enemy has spread false rumors about them in the village, making them feel like they have no choice but to leave. Another plot twist might be that they discover a long - hidden truth about their families that is connected to some ancient power outside of Konoha, which compels them to leave in search of answers.
Well, it could be that Sasuke decides to join Naruto in leaving. They've always had a complex relationship. Maybe Sasuke sees Naruto's reasons for leaving as valid and decides to support him, which strengthens their bond.
One major challenge could be dealing with new enemies. Outside of Konoha, there are different ninja clans and organizations that may not be friendly. They have to adapt to new fighting styles and strategies of these opponents. For instance, they might encounter powerful rogue ninjas who are more ruthless than the ones they faced in Konoha. Another challenge is that they may have to deal with their own internal conflicts while on the road. Naruto might struggle with feelings of homesickness and Sasuke with his inner demons related to his past and his thirst for revenge.
Sasuke might initially be shocked. He has always seen Sakura as someone connected to Konoha, so her leaving would be unexpected. He could be concerned about her safety, especially if she leaves without proper preparation or protection.
One possible fanfic could be 'Abandoned Bonds'. In this story, Naruto's departure from Konoha sets off a chain of events where Sasuke is seen in a negative light as he fails to understand Naruto's reasons for leaving. However, it's important to note that Sasuke - bashing can be a divisive concept among fans as Sasuke has his own complex backstory and motives.
If Sasuke raised Naruto, Naruto would become very attuned to Sasuke's emotions. Sasuke is not one to show his feelings easily, but Naruto, growing up under him, would learn to read his every mood. Their relationship would also be influenced by the outside world. The other ninja clans might view this relationship with suspicion. However, Naruto and Sasuke would be united in facing any challenges, with Naruto learning from Sasuke's combat skills and Sasuke learning about compassion from Naruto.
