They could also have adventures together outside of the village. Maybe they go on a quest to find a lost ninja art that was important to one of their predecessors. During this adventure, they rely on each other's skills, Naruto's strength and Hinata's intelligence. This would bring them closer as they face challenges side by side and see new sides of each other.
Communication is key. In the fanfic, they could have deep conversations about their fears and hopes for the future. Naruto might share his concerns about the safety of the village during difficult times, and Hinata can offer her support and insights based on her own experiences. This would make their relationship more profound as they understand each other on a deeper level.
Their relationship can be developed by showing them facing challenges together. For instance, when Naruto has to make tough decisions as Hokage, Hinata can be there to support him morally. And when Hinata has to deal with her family's expectations, Naruto can encourage her to follow her own path. This mutual support can deepen their connection.
You could also explore their relationship in the context of parenting. Show how they have different parenting styles but still work together to raise their children. For instance, Naruto might be more lenient and want their kids to have fun and explore, while Hinata is more cautious and focuses on teaching them proper ninja etiquette. The way they resolve these differences can show the strength of their relationship.
Their relationship could be developed through shared challenges outside of the village. For example, they could go on a diplomatic mission together to a far - off land where they face cultural differences and political intrigue. They'd have to rely on each other more than ever.
Their relationship can be developed through shared adventures. For example, going on a mission to rescue hostages. Naruto can teach Mitsuki how to better understand the emotions of the hostages and use that in battle strategy. This would deepen their bond as teacher - student and friends.
Hinata can be developed by making her more assertive in her relationship with Naruto. Instead of always being the shy one, she could take the initiative in some situations. Like when they face an enemy, she could be the one to come up with a battle plan and Naruto would follow her lead for once. This would show her growth and confidence.
At first, Naruto might be a bit shocked when he finds out about Hinata's hanyou side. But then he would start to see her in a new light. He could encourage her to be more confident in herself, which would deepen their bond.
To develop Naruto further, we could see him struggle with the political aspects of being a Hokage. Hinata could be developed through her relationships with other female ninjas in the village. She could form a sort of female ninja council to address issues specific to women in the ninja world. Tenten could be developed by having her mentor a young ninja with a passion for weapons, which would force her to reflect on her own journey and growth as a weapon - user.
Their relationship could be developed further through mutual understanding. For example, Naruto could learn more about Kurama's past and the reasons for his anger and hostility in the beginning. This would make Naruto more empathetic towards Kurama, and Kurama in turn could start to trust Naruto even more.
Hinata could be developed by showing her taking on more leadership roles. For example, she could lead a small team on a mission and show her strategic thinking and decision - making skills. This would also show her growth from a shy girl to a confident ninja.
Their relationship can be developed through shared adventures. For example, they could go on a journey to find a rare herb that is said to enhance chakra control. During this journey, they face difficult terrains and enemies. Naruto can show his concern for Hinata's well - being, and Hinata can use her intelligence to help Naruto out of tricky situations, thus bringing them closer.
