One possible plotline could be that Kabuto has some ulterior motives related to the power dynamics between Sasuke and Naruto. He might think that by creating this rift through false accusations of cheating, he can gain some advantage in the ninja world. So, he sets up elaborate scenarios where Sasuke is wrongly implicated, and the story could follow how Sasuke and Naruto deal with this strain on their relationship, with Naruto initially being heartbroken but then starting to suspect something is amiss.
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.
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.
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.
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.
One possible plotline could be a comical situation where Sasuke is exasperated with Naruto's silly behavior and decides to 'spank' him as a form of discipline in a very light - hearted and friendly way. It could be part of their banter and growth as friends.
In a fanfic with a female Sasuke, the plotline might include her using her femininity as a strength in the ninja world. She could be more in tune with nature - based jutsu, for instance, and use that to her advantage. Her journey could also involve breaking gender barriers in the Hidden Leaf Village. She might be the first female to attempt certain high - level ninja training or missions. And her relationships with other characters like Sakura could be more complex, with a mix of competition and sisterly support as they both strive to be great ninjas in their own ways.
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.
Maybe to explore different character arcs. The writer might want to see how Sakura would develop as a character if she strayed from her loyalty to Sasuke. It could also be a way to introduce new characters or relationships into the Naruto fanfic world.
One possible plot could be Sasuke getting involved with another character due to a misunderstanding or a sense of being drawn to someone who seems to understand a different side of him that he feels Sakura doesn't. For example, if there's a new female character who shares his dark past experiences more directly.
In some plotlines, it could be a matter of self - discovery for Cas. He might think that his relationship with Dean is too constricting or that he needs to explore other aspects of love and connection. So, he cheats on Dean. However, this often leads to a lot of drama, with Dean finding out, and then there are a series of events like arguments, reconciliations, or even the end of their relationship depending on how the writer wants to take the story.
One possible plotline could be that Naruto and Fem Sasuke face a lot of challenges as they prepare for the arrival of their baby. Maybe they have to deal with the reactions of their friends and the ninja community, who might have mixed feelings about their relationship and the upcoming birth.
