Perhaps Fem Sasuke is brainwashed by an enemy. This enemy could use some sort of mind - control jutsu on her. They plant false memories or ideas in her head, making her believe that Naruto has become a danger. She then betrays him, but as the story progresses, she starts to break free from the mind control and realizes her mistake.
Well, in a fanfiction context, it could be possible if we consider a crossover universe where Naruto somehow ends up in the Star Wars galaxy. Maybe he's brainwashed by the dark side's influence which is similar to some dark forces in his own world. This could lead him to betray the Jedi ideals that he might have adopted during his time there.
Perhaps Fem Sasuke in this fanfiction has a different view of the world. She might believe that Naruto is a threat to her goals or to the future of the ninja world she envisions. It could also be that she has some deep - seated emotional pain that she blames Naruto for, and that leads her to kill him.
Maybe Naruto is framed by a powerful enemy within Konoha. False accusations are made against him, and instead of getting a fair trial, he is hunted down. This injustice could make him turn his back on the village that he once loved and swore to protect.
Their relationship can be developed through shared experiences. For example, going on dangerous missions together. Each time they face a new threat, they learn more about each other's abilities and personalities. Naruto's positive attitude can slowly break down Fem Sasuke's more reserved nature.
Well, Naruto and Fem Sasuke's relationship could start with their mutual understanding of each other's pain. They've both had difficult pasts. Naruto, being the lonely kid, and Sasuke, with his clan's tragedy. In a fanfiction, Fem Sasuke might be more in touch with her emotions. They could start as rivals still, but gradually, Naruto's unwavering determination to bring Sasuke back could turn into a deeper affection. Maybe during a mission together, they could share a moment of vulnerability and realize their feelings for each other.
Well, often their relationship development is a slow - burn process. At first, Fem Sasuke may be standoffish towards Naruto because of her pride in the Uchiha clan and her Sharingan abilities. But as they are forced to work together on various missions, Naruto's unwavering belief in her, despite her flaws, starts to break down her walls. They gradually become friends, and in some fanfictions, it even develops into a romantic relationship. This is especially true when the author focuses on how their individual growth as ninja is intertwined with their relationship. For instance, Naruto might learn new combat techniques from Fem Sasuke's Sharingan - based moves, and in return, he teaches her about the power of friendship and perseverance, which deepens their connection.
At first, it might be a bit rocky. They are both strong - willed individuals. Naruto is used to being the center of attention and having his own way, and fem Sasuke has her own ideas. But as they live together, they start to understand each other more. For example, Naruto realizes that fem Sasuke's aloofness is sometimes just her way of protecting herself. And fem Sasuke sees that Naruto's boisterousness is his way of showing his love for people. So they gradually become more in tune with each other's needs and wants.
Their relationship might start off very one - sided. Sasuke is in control as the 'owner' of fem Naruto, who is his pet. But gradually, fem Naruto could show her unique charm and strength, making Sasuke start to respect her more. This could lead to a more equal relationship over time.
In a fanfiction of Naruto marrying Fem Sasuke, the story could start with their post - war relationship. They might start as friends who train together. As they train, they start to notice little things about each other. Naruto might be attracted to Fem Sasuke's strength and determination, while she might be drawn to his unwavering spirit. Eventually, their friendship blossoms into love, and they decide to get married. Their wedding could be a grand event with all their friends and allies from the ninja world in attendance.
Well, perhaps in the fanfiction, Fem Sasuke's blindness is a result of some dark jutsu. Naruto, with his determination, tries to find a way to restore her sight. Along the way, they encounter many old foes and new allies. The story could explore how Fem Sasuke copes with her new disability and how it changes her ninja skills, for example, she might develop new ways of using her Sharingan even without sight.
