Naruto may start training even harder. Since Hinata has always been a source of motivation for him, her absence could make him strive to be better in the hope that when she returns, she'll see a stronger and more capable Naruto. He could also be seen daydreaming about her during breaks or when he's supposed to be relaxing, a clear sign that he misses her.
Naruto could constantly talk about Hinata to his friends. He might say things like 'I wonder what Hinata is doing right now' or 'I really miss Hinata's cooking'. This shows that she's always on his mind. Also, he could visit places they used to go together often, like a particular training ground or a spot in the village where they had a conversation.
In many fanfictions, Naruto shows his protectiveness of Hinata by always being by her side during dangerous situations. For example, when there are enemy attacks, he quickly positions himself in front of Hinata to shield her from harm.
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.
Well, first of all, Jiraiya gives Naruto a sense of family. Naruto has always been an orphan, and Jiraiya steps in as a father figure. He shows concern for Naruto's growth, not just as a ninja but as a person. He encourages Naruto to be true to himself. In terms of ninja training, he doesn't just teach Naruto techniques but also the strategy and wisdom behind them. And when Naruto makes mistakes, Jiraiya is there to correct him in a patient and understanding way, which is a very important quality of a good godfather.
One of the ways Naruto is like his father is in his self - sacrifice. Minato sacrificed himself to save the village and Naruto has on several occasions put himself in harm's way for the greater good. He doesn't hesitate to give his all, whether it's against powerful enemies or for the safety of his comrades, just like Minato did.
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.
In many fanfictions, Hinata calms Naruto with her gentle presence. Just by being there beside him, her quiet and kind nature has a soothing effect on Naruto, who is often so full of energy and impulsiveness. For example, she might hold his hand or give him a soft, understanding look that makes him feel at ease.
Fanfiction contributes by exploring different scenarios. For example, it can show them in everyday situations that the original series might not have covered. This gives a more complete view of their relationship.
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.
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.
He would be very angry. Naruto is not one to take betrayal lightly.
