Well, Naruto is a very emotional person deep down. If Sasuke cheats on him in a fanfic, he may feel so heartbroken that suicide seems like an option. But he has so many friends like Shikamaru, Sakura, etc. who would probably notice his distress. They would try to talk him out of it. And Naruto also has his dreams for the village and his own growth. So, while the pain of Sasuke's betrayal could be overwhelming, he has many reasons to keep living and fighting.
If Sasuke cheats on Naruto in the fanfic, Naruto's reaction leading to the thought of suicide could be complex. He might think that all the efforts he put into their relationship, whether it was friendship or something more, were in vain. But on the other hand, his ninja way would also be a factor. He always stands up for what's right and to protect others. So, he might struggle between his personal pain and his sense of duty. In the end, it depends on how the author wants to portray his internal conflict, but there are always elements within Naruto's character that could either lead him towards or away from the idea of suicide.
In such a fanfic, Naruto might first feel extreme betrayal. He has always considered Sasuke a close friend or more. If Sasuke cheats on him, he could feel that his world has crumbled. He might initially go into a state of shock, unable to believe what has happened. Then, the thought of suicide could creep in as he might feel that there is no one left to trust or that his life has lost its meaning without Sasuke's loyalty. However, Naruto is also a strong - willed character, so he could also choose to rise above it and prove to Sasuke and himself that he doesn't need such a person in his life.
I'm not sure if there is such a specific fanfic. Fanfiction can cover a wide range of scenarios, but cheating themes might not be very common in the Naruto fanfic world, especially considering the strong bond between Sasuke and Naruto. However, with the vast amount of fanfiction out there, it's possible that one exists.
Well, it might show Sasuke being put in compromising situations by Kabuto's schemes. For example, Kabuto could use his medical ninjutsu knowledge to create illusions that mislead Naruto into believing Sasuke is unfaithful. The plot could then revolve around Naruto's reaction and how he tries to uncover the truth.
One reason could be to create a lot of angst. If Sasuke cheats, it would deeply hurt Naruto and cause a rift in their relationship, which could lead to a lot of emotional turmoil for both characters. This would make for a very dramatic story.
Some fanfic authors might write it as a form of wish - fulfillment. They might prefer the Naruto - Sakura relationship more than the Sasuke - Sakura one. So, they create a scenario where Sakura turns to Naruto in a romantic way. Additionally, it could be a way to explore the characters' personalities further. For example, how Sasuke would handle being betrayed and how Naruto would deal with being involved in such a situation. It gives a chance to dig deeper into their emotional and moral aspects.
Naruto might be heartbroken. He's a very emotional character, so he could cry a lot and feel a deep sense of loss.
To avoid making Naruto's suicide seem forced, the fanfic writer should first establish a deep emotional connection between Sasuke and Naruto. Show their relationship evolving over time. Then, when Sasuke cheats, it should be a major blow. But also give Naruto other things to live for. For example, his relationships with other friends like Iruka - sensei or his determination to protect the village. Maybe Naruto could initially think about suicide, but then have an epiphany about his other important values.
Naruto's reaction would be complex. He would be devastated because his bond with Sasuke is so deep. However, he also trusts Sasuke to an extent. So, he would be torn between his immediate emotional response of anger and his long - standing faith in Sasuke. He might start to look for clues and evidence, and in the process, he could end up uncovering Kabuto's devious plan while also reaffirming his friendship with Sasuke. He would probably be more determined than ever to set things right and prove Sasuke's innocence if he is indeed innocent.
There might be some fanfics out there with such a plot, but it's not a positive or common representation of the Naruto characters. In the Naruto series, Hinata has always admired Naruto from afar and they end up together. Sasuke has his own story arc that is mainly focused on his revenge and redemption. Changing their relationships in such a way in a fanfic seems like a distortion of the original story's essence.
In a fanfiction where Sakura cheats on Sasuke with Naruto, there could be many consequences. Firstly, it would shatter the trust within Team 7. The camaraderie and unity that they had built over the years would be severely damaged. For Sakura, she might lose the respect of her friends and comrades. In the Naruto world, reputation is important. Naruto himself might be ostracized by some in the village who see him as a home - wrecker, despite his good intentions. And Sasuke could potentially go on a dark path again, seeking revenge or just distancing himself from everyone. Overall, it would create a lot of chaos and emotional upheaval.
Fans would likely be divided. Some fans who like exploring unconventional and darker storylines might be interested in such a fanfic. They might see it as a creative exploration of the characters. However, many fans who are loyal to the original relationships in the Naruto series would probably be outraged. They would feel that it goes against the essence of the characters and the positive relationships that were built up over the course of the series.
