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.
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.
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 He could become withdrawn and less likely to jump into things as he usually does.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.
Perhaps Hinata will be really confused at first. She could ask her friends for help, like Naruto. Together, they would try to figure out where the baby came from and what to do with it. Since Hinata is kind - hearted, she'll surely do her best to keep the baby safe and comfortable.
Another possibility is a complete character distortion in the fanfiction. The writer might decide to create a 'bad Naruto' version where he has lost all his positive traits. However, this is quite far - fetched considering the strong foundation of Naruto's character in the original series. It would be a very different and probably controversial take on the Naruto - Hinata relationship.
One possible outcome could be Naruto feeling extremely hurt and betrayed. He might distance himself from Sakura completely. In the context of fanfiction, he could also focus more on his training and his other friendships, like with Shikamaru or Kakashi. He might become more determined to prove himself without Sakura's support.
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.
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.
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.
Hinata might be very cautious at first. She has been deeply hurt by Naruto's cheating, so even though he regrets it, she would need time to heal. She may not immediately forgive him and might keep her distance to protect herself.
One way could be through their leadership. Naruto, with his experience and strength, and Hinata, with her kind heart and support. They could start by gathering the remaining Uzumaki clansmen. Then, they might use Naruto's influence to get resources from the other villages. Hinata could help in planning the layout of the rebuilt village, making it a place full of love and harmony, just like her own family environment.
