Well, as Naruto becomes Hokage, their relationship changes in many ways. Firstly, they have more responsibilities towards the village together. Hinata might be more involved in village events by Naruto's side. Naruto also becomes more protective of Hinata, seeing her as an important part of his new life as a leader. He may show his affection for her more openly in front of the villagers, which is a big change from before. Also, they might have more private moments where they discuss the future of the village and their family, strengthening their bond.
Well, it could strengthen their bond. Naruto being hurt might make Hinata more protective and caring towards him. This could lead to Naruto realizing Hinata's true feelings for him more deeply, and in turn, he might start to see her in a new light, growing closer to her.
The fanfiction could explore their relationship by having them communicate in a more in - depth way. Since they are part of Team 7, they are constantly in each other's company. Naruto might start to notice the little things about Hinata, like how she always blushes when he looks at her. Hinata, on the other hand, might become more confident around Naruto because of their Team 7 experiences. There could also be situations where they have to trust each other with their lives, which further cements their relationship.
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.
Often, the jealousy Hinata feels acts as a catalyst. It makes her more determined to get closer to Naruto. So, she starts to be more confident around him. Naruto, seeing this new side of Hinata, becomes more interested in her. Their relationship then moves from Naruto just seeing Hinata as a friend to seeing her as someone he could have a deeper connection with.
Their relationship would likely become even stronger. With Naruto as Hokage, Hinata would be more in the public eye as his partner. They would have to rely on each other more for emotional support in the face of the high - pressure situation of leading the village.
In fanfiction, their relationship often deepens as they face parenting challenges together. They support each other more and become more in tune with each other's feelings.
In some of these fanfictions, their relationship develops as they gradually remember their past. They start having strange feelings and dreams, which lead them to explore their connection. As they do so, they start to fall in love all over again, just like in their previous lives.
One interesting plotline could be how Hinata supports Naruto in his journey to become Hokage. For example, she might use her Byakugan to gather information for him on potential threats to the village. Another could be their relationship development while Naruto is facing the challenges of leadership. Maybe Naruto realizes just how much Hinata means to him during a particularly tough time as Hokage - in and out of the office.
In some fanfictions, Naruto is completely oblivious at first. He doesn't understand why Hinata is acting strange. He just goes about his day, being friendly as usual. But as Hinata's jealousy becomes more obvious, he might start to notice that something is wrong. He could be confused and try to ask Hinata what's bothering her.
Naruto could change Konoha by promoting unity. He might organize village - wide events where everyone, from the strongest jounin to the youngest genin, participates. This would strengthen the bonds between the villagers.
