In a fanfic where Naruto finds Hinata cheating on him, it would be a huge blow to his world. Naruto has always seen Hinata as someone very special. He might initially feel like his whole world is crumbling. His friends would probably notice the change in him right away. He could become withdrawn and less likely to jump into things as he usually does. He may also have a hard time trusting others in the future, especially in romantic relationships. And depending on how the story is written, he could either forgive Hinata after a long and arduous journey of self - discovery and understanding, or he could completely cut her out of his life and move on, albeit with a broken heart.
He might feel extremely betrayed and angry. In some cases, he could cut off all ties with Hinata immediately. Naruto is a passionate character, and such a discovery would shatter his trust in her.
For Hinata, if she's actually innocent, she would be heartbroken that Naruto thought she could cheat. She might have to fight hard to prove her innocence. If she was at fault, she would likely face a lot of guilt and the loss of Naruto's love, which was something she deeply cherished. In the fanfiction world, this could also lead to changes in the social dynamics among their friends. Their friends might be divided, some believing Hinata and some believing Naruto's initial perception. It could create a rift in the whole group.
Another possibility is that the writer wanted to explore different character reactions. Naruto might initially be devastated. He could go through a phase of disbelief and then anger. However, if it's a well - written fanfic, there would likely be a resolution where the truth comes out and their relationship is either repaired or redefined.
He would probably have to work really hard to repair the relationship. In fanfiction, Naruto's regret might mean he has to face Hinata's pain directly. Since Hinata has always been so devoted to Naruto, his cheating would be a huge shock. Naruto might try to be more open and honest about his feelings in the future. He could also face social consequences in the village. People might gossip about him and look at him differently. To fix things, he would need to show that he has truly changed and is committed to Hinata again.
The story could take a dark turn. Naruto might become bitter and start to isolate himself. His friends would worry about him and try to bring him back to his old self. There could be a lot of drama and tension within the group.
Well, in the 'hinata catches naruto cheating fanfiction', it really depends on how the author wants to develop the story. Maybe Hinata, after catching Naruto, decides to keep it a secret at first to figure out more about the situation. She might start observing Naruto more closely and try to find out who he is cheating with. And then, based on what she discovers, she will take different actions. For example, if it's a misunderstanding, she will feel guilty for doubting Naruto. But if it's true, she might seek advice from her friends or family on how to deal with it.
He might be initially shocked. Naruto has been so focused on his goals like becoming Hokage that he may not have expected Hinata's love. He could be really touched that someone as kind and gentle as Hinata has had such deep feelings for him all this time.
In such a fanfiction scenario, Naruto would likely be extremely hurt. He has deep feelings for Hinata, so finding out she cheats would shatter his trust. He might initially go into denial, not wanting to believe it. Then, he could become angry and might distance himself from Hinata. His friends would probably try to console him, but it would take a long time for him to get over the betrayal.
The fanfic could show Naruto's initial anger and confusion clearly. For example, having him raise his voice and ask Hinata how she could do this to him. Then, it could gradually show his sadness seeping in as he realizes the relationship might be over.
Sakura might find out about it later. She would probably tease Naruto about it, making him even more flustered. As for Sasuke, he might just roll his eyes at the whole situation, thinking it's just another one of Naruto's silly misadventures. But if the story is set in a more serious context, Sasuke could also see it as a sign of Naruto's growing closeness to Hinata and might have some complex thoughts about it.
