It could be the influence of a powerful enemy or a dark power. Suppose there is an enemy who has the ability to manipulate emotions or a dark power that corrupts Naruto's mind. This could lead him to change his personality and become more like Gaara. For example, if the enemy makes Naruto feel alone and unloved, he may start to develop the same cold and distant behavior that Gaara once had.
The situation where Gaara becomes obsessed with Sakura fanfiction could also have an impact on his own self - perception. He might start to compare himself to the characters in the fanfiction, either feeling inadequate or trying to be more like the idealized versions. This could either make him strive to be a better person in a positive way, or it could lead to some self - doubt and confusion as he tries to fit into this new - imagined world related to Sakura in the fanfiction.
One idea could be that in this fanfiction, Fem Gaara is in debt to Naruto for saving her life. As a result, she decides to become his servant. This could lead to many comical situations where Naruto, being his usual clumsy self, has no idea how to handle having a servant. For example, he might accidentally give her tasks that are inappropriate or too easy, and Fem Gaara has to figure out how to deal with it while still maintaining her pride.
The relationship would likely be a complex one. Naruto is a character who values justice and friendship. When Fem Gaara becomes his prisoner, he might struggle with his own beliefs. He has to keep her locked up, but he also feels a sense of guilt. This could lead to him trying to make her time as a prisoner more bearable. Fem Gaara, being proud, would resist at first. But as Naruto continues to be empathetic, she might open up. They could share stories about their upbringings, which are both filled with hardships. Through these exchanges, a deep connection could form between them, changing their initial hostile relationship into one of mutual understanding and respect.
The Naruto universe would be in for some chaos. Gaara's new obsession could disrupt the balance of power dynamics. If he starts to prioritize the fanfiction - related ideas about Sakura over his duties in the Sand Village, it could lead to political unrest or at least some tension between the Sand and Konoha. After all, his actions as a leader are important for maintaining peace between the villages.
One possible plot could be that there has been a misunderstanding between their villages. Naruto, believing Fem Gaara to be a threat to Konoha, captures her. However, as time passes, Naruto realizes that she was misjudged. He starts to see her vulnerability and they gradually form an unexpected bond. Through their interactions, they learn more about each other's pasts and the pain they've endured. This could lead to a change in Naruto's perception of Fem Gaara and ultimately, he might work towards her release and forging an alliance between their villages.
Naruto might become more withdrawn like Gaara was initially. Gaara was isolated due to his power and the fear others had of him. So Naruto could start to keep to himself more, losing some of his boisterous and friendly nature.
Character development in this fanfiction could be quite complex. Fem Gaara might struggle with her new role, which could lead to her exploring her own identity outside of being a powerful ninja. She could become more humble as she realizes there are things she can learn from Naruto. Naruto, too, would change. He might become more confident in his abilities as he has someone relying on him. Their relationship could evolve from a master - servant dynamic to a more equal partnership, with both characters growing and maturing as a result of their time together.
One possible story could be that Sakura goes to the Sand Village for a medical mission while Gaara is Kazekage. They start to interact more, and Gaara is impressed by Sakura's strength and kindness. Eventually, they form a strong friendship that helps in strengthening the bond between the Leaf and Sand villages.
