Separation is also a common theme. Maybe Naruto has to leave the village for a long time, leaving Hinata behind. The distance and the lack of communication during this time can be a source of hurt for both of them. It often tests their relationship and loyalty.
In some cases, Naruto could be deeply hurt and withdraw from Hinata. He might question their relationship and whether he misjudged her all along. If the hurt is physical, he may also be more cautious around her in future interactions. For example, if she accidentally used a strong jutsu on him during training, he might be hesitant to train with her again without proper precautions.
There might be a story where Naruto accidentally says something really hurtful to Hinata during an argument. For example, he might compare her unfavorably to Sakura in a moment of anger. This then causes a rift between them as Hinata is deeply hurt and Naruto has to figure out how to make it up to her.
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.
One great source for Naruto and Hinata fanfiction could be FanFiction.net. You can search for stories specifically focused on their relationship there. There are often new and interesting takes on their story, from how they first fell in love to their married life in the future.
Naruto might be hurt by fanfiction in various ways. For example, some fanfictions could distort his character. They might portray him as overly cruel or weak, which goes against his original essence in the official story. This can mislead fans who are new to the Naruto universe and create a wrong perception of him.
In a fanfiction scenario, Naruto being a jealous husband might lead to some internal conflict. He has always been confident, but when it comes to Hinata's affection, he might worry that he's not doing enough. So, when he sees Hinata having a normal conversation with someone else, he might start to doubt himself. This self - doubt can be explored in the story, and through his relationship with Hinata, he can learn to overcome it.
A Naruto x Hinata fanfiction could focus on a mission they go on together during Naruto Shippuden. They are forced to rely on each other in a dangerous situation. Hinata gets injured protecting Naruto, and Naruto is filled with a new - found determination to protect her. This experience deepens their bond, and Naruto starts to see Hinata in a whole new light, leading to the start of their romantic relationship.
One reason could be envy. Maybe Naruto sees Hinata as having something he doesn't, like a more stable family situation, and he lashes out in jealousy. Another reason might be that he's just being a typical, rambunctious kid who doesn't realize the impact of his words or actions on Hinata.
Hinata supports Naruto by being his emotional anchor. When facing the Juubi, Naruto can get caught up in the chaos and danger, but Hinata is there to remind him of his humanity and the things he's fighting for. For example, with a simple look or a kind word, she can calm him down in the heat of battle.
