One possible plot could be that Naruto suffers a head injury during a battle. As a result, he forgets about Sasuke completely. His friends initially don't notice, but as time passes, they realize Naruto's behavior towards Sasuke - related things is strange. For example, he doesn't get angry when Sasuke is mentioned like he used to. Then they try to help Naruto regain his memories of Sasuke through various means, like showing him old photos or taking him to places they used to go together.
It could be a rogue ninja who has a vendetta against Sasuke. This ninja knows that Naruto's bond with Sasuke is strong, so he uses a special jutsu to make Naruto forget Sasuke, hoping to break Sasuke's spirit. By removing Naruto from Sasuke's life in this way, the rogue ninja believes he can defeat Sasuke more easily.
Obviously, Sakura and Sasuke are the main characters. Even though Sakura forgets Sasuke, their relationship (or the lack of it in this case) forms the core of the story.
One idea could be that Sakura forgets Sasuke due to a magical spell gone wrong. This could lead to her living a completely different life, free from her past obsession with him.
In such a fanfiction, Naruto might find himself in a very lonely and confusing situation. He would have to relearn about his relationships and the world around him. Maybe he'd be more cautious as he doesn't remember who is friend or foe.
One possible plot twist could be that Naruto's memory loss leads to him accidentally endangering his former teammates. For example, he might unknowingly reveal secrets to the wrong people. Another could be that his forgotten bond with Team 7 causes him to form new alliances that are initially at odds with his old team. Maybe he teams up with former enemies who manipulate his lack of memory. Also, it could lead to a situation where Team 7 has to reteach Naruto about their shared past and values, which would be a really emotional and character - developing journey for all of them.
Sakura would be heartbroken. She'd likely spend hours upon hours by Naruto's side, trying to jog his memory with stories of their adventures together. She might even get a bit overbearing in her attempts. Sasuke, who has his own complex relationship with Naruto, would be conflicted. He'd see Naruto's forgetfulness as a sign of weakness at first but then realize the importance of their bond. Kakashi, being the experienced leader, would start by observing Naruto carefully to see exactly how much he has forgotten and then start a systematic process of helping him remember.
One way the plot could develop is that Naruto begins to trust the wrong people because he doesn't remember who he should trust. This could lead to him getting into dangerous situations. Meanwhile, his true friends are desperately searching for a way to reverse his memory loss. As the story progresses, Naruto might start to have flashes of his old memories, which would add some mystery and hope to the plot.
