In many fanfictions, Sakura might choose Sasuke. They have a long - established relationship, with Sasuke being someone she has loved since childhood. Her feelings for him are deep - rooted and often in fan - created stories, she remains loyal to those initial feelings.
Maybe it's about protecting Sakura. Itachi might think that Sasuke isn't the right person for Sakura and wants to protect her from Sasuke's darker side. And Sasuke, on the other hand, believes he can protect Sakura better than Itachi and that Itachi has no right to interfere.
One reason could be Naruto's power. In the Naruto universe, Naruto has great power, and both Itachi and Sasuke might see Naruto as a key to achieving certain goals. Itachi might want to protect Naruto because he sees Naruto as a force for good in the future of the ninja world. Sasuke, on the other hand, may view Naruto as a rival in terms of power and influence, and in fanfiction, this could lead to a fight between them over Naruto.
Itachi. He was a highly skilled and intelligent shinobi. His Sharingan abilities were extremely powerful, and he had a lot of combat experience. He also had a strategic mind, which would give him an edge in a fight over Naruto.
One common theme is redemption. For example, Sasuke often has a journey of redeeming himself after his dark turn. Another theme is friendship, like how Naruto's unwavering friendship for Sasuke is a central part. Also, the idea of sacrifice, as seen with Itachi's great sacrifice for the village and his brother.
Fanfiction often takes the existing characters of Sasuke and Sakura and gives them new scenarios. In this 'do - over' concept, perhaps it's about them re - experiencing a part of their story. For example, if there was a fight or a misunderstanding in the original story, the fanfiction might have them go through it again with different reactions and outcomes. It could also be about their personal growth and how this do - over affects their individual development as characters.
Well, one possible plot could be that Sakura, feeling neglected by Sasuke, finds comfort in Itachi's more empathetic nature. Itachi, perhaps, has his own reasons for getting involved with Sakura, like trying to understand the nature of relationships better. However, this would be a very complex and controversial plot as it goes against the established relationships in the original Naruto series.
In the fanfiction, Itachi might be acting according to some secret mission that endangers Sakura's life. Sasuke, who has a strong bond with Sakura now, won't let that happen. He jumps in and uses his ninja skills. Sasuke could have developed some new jutsu that he uses to counter Itachi's attacks. This not only saves Sakura but also shows Sasuke's growth as a ninja. And Sakura, in turn, might be in the middle of researching some important medical ninja stuff that Itachi's actions could have disrupted if not for Sasuke.
In fanfiction, their relationships could be reimagined in many ways. For example, Itachi could have a more mentoring role towards Naruto, sharing his wisdom from a different perspective. Sakura might be more assertive in her relationship with Sasuke, not just being the passive admirer. And Sasuke could find a new sense of brotherhood with Naruto that goes beyond their rivalry, all because of different plot twists and character developments that fanfiction writers can create.
Well, Naruto has a very warm and persistent personality. He's always there for his friends, and he has a big heart. In fanfiction, Sakura might see these qualities in Naruto and realize his true value. He's the kind of person who can make her laugh and feel safe, which could be very appealing compared to Sasuke's more brooding nature.
