The Pain Invasion is a turning point for their relationship in fanfiction. Before, Naruto was mostly oblivious to Hinata's feelings. But after, he starts to notice the little things about her. Hinata, who was always shy, becomes a bit bolder in her interactions with Naruto. She might even give him small gifts or tokens of her affection. Naruto, in turn, begins to seek her company more. He might go to her for advice or just to have a quiet moment. Their relationship evolves from a one - sided admiration on Hinata's part to a mutual understanding and the start of something deeper, like a budding romance or at least a very strong friendship.
Well, it's possible that Hinata becomes more confident around Naruto after the Pain Invasion. She might be more forward in expressing her emotions, which could lead to Naruto reciprocating her feelings. Maybe they go on adventures together in the village, helping people out and in the process, their bond grows stronger. They could also have some really deep conversations about their pasts, their dreams, and how they see the future of the village, which further cements their relationship.
Their relationship could develop through shared trauma. During the Pain Invasion, they face a great threat together. This might make them rely on each other more and understand each other better. For instance, Naruto might see Ino's courage in the face of danger, and Ino could see Naruto's selfless nature up close.
The relationship would likely become more intimate. They'd have more time to just be with each other, sharing their thoughts and feelings without any rush. For example, they could have long conversations at night before going to sleep.
Naruto could also be more focused. The experience of the Pain invasion made him realize the importance of being fully present and concentrated during battles and training. He might have less of his usual goofiness and be more serious about his growth as a shinobi.
In many fanfictions, after the Pain arc, Naruto and Hinata's relationship often deepens. Naruto starts to see Hinata in a new light. He realizes her strength and her unwavering feelings for him. This can lead to more interactions between them, like Naruto becoming more protective of Hinata and Hinata being more confident in expressing her love for Naruto.
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.
Their relationship would likely become even more intimate. Naruto would be more protective of Hinata. He would constantly be by her side, making sure she's safe and comfortable. Hinata, on the other hand, would rely on Naruto more, sharing her fears and joys about the pregnancy with him.
Their relationship would likely become more interdependent. As Jinchuuriki, they would have to rely on each other for support and understanding. For instance, they might train together more often to master their powers, which would bring them closer.
In this kind of fanfiction, Hinata's care often deepens their bond. Naruto, who has always been somewhat alone, starts to rely on Hinata more. This reliance can turn into a deeper form of love. As Hinata takes care of his physical and emotional needs, Naruto realizes how important she is to him, which can lead to a more romantic relationship between them.
In fanfiction, they might become closer friends. Naruto's heroic deeds during the Pain Invasion could make Ino see him in a new light. She may start to respect him more deeply and offer him more emotional support. They could also train together sometimes, with Ino learning some of Naruto's unique ninja skills.
