For example, they would need to find shelter and food, and this shared struggle could bring them closer.
Their relationship could turn into a mentor - mentee type. Naruto, with his vast experience and strong will, could teach Temari some of his unique ninja skills, and Temari, being from the Hidden Sand with her own set of skills, could show Naruto different ways of handling situations. This exchange of knowledge could deepen their relationship.
At first, they might be at odds. Temari is from the Hidden Sand and Naruto from the Hidden Leaf, and their villages have had a history of conflict. But as they are banished and have no one else but each other, they gradually start to understand each other better. They learn about each other's pasts, dreams, and fears, which transforms their relationship from a tentative alliance to a deep friendship or even something more romantic over time.
It could start with mutual respect. Naruto, despite being banished, still has his strong will and Temari would respect that. They might begin by sharing stories of their past and their respective villages. This would lead to a growing understanding of each other.

Their relationship might start off rocky. Naruto being banished and Kurotsuchi being from a different place with her own set of beliefs. But as they interact more, they'll find common ground. Maybe they start with small acts of kindness towards each other, like Naruto helping Kurotsuchi with a difficult task, and Kurotsuchi in turn providing Naruto with shelter. This could gradually lead to a deeper understanding and a romantic relationship could blossom.
Naruto might also initially feel a sense of abandonment. However, his kind - hearted nature could lead him to try and see the good in the situation. He could start to explore the world outside, learning about different cultures and ninja techniques. He may use this experience to become more empathetic towards others who have also faced hardships, and in the long run, this banishment could be a turning point in his life to become an even greater ninja.
Naruto could also become determined. Since he is 'godlike' in this fanfiction, he might see this as an opportunity to grow even stronger away from the village. He might set out on a journey to master his powers fully and prove himself, with the intention of one day coming back to the village and showing everyone that he was wrongly banished.
At first, their relationship might be one of mistrust. Naruto is wary of the Kyuubi as he's always been taught to fear it.

Itachi might initially be hesitant to fully accept Naruto. But as Naruto proves his loyalty and determination, Itachi would open up more. They could start to collaborate on various missions, and through these shared experiences, their bond would strengthen. Naruto could also introduce Itachi to his friends from Konoha (if they were to interact later), which could further change Itachi's view of the world outside of his own dark past.
