One possible plot could be that future Sakura, with her advanced medical skills and battle experience, goes back in time and meets a younger Sasuke. She might try to prevent some of the tragedies that Sasuke later endures. For example, she could warn him about Orochimaru's true intentions, which would change the course of Sasuke's journey. This would also lead to different interactions between Sakura and Sasuke compared to the original story. Their relationship might develop in a more positive way earlier on, as Sakura from the future has a deeper understanding of Sasuke's pain and the consequences of his actions.
Their relationship would likely become more complex. Since future Sakura has more knowledge about Sasuke, she would approach him differently. She might be more confident and less shy around him compared to her younger self. Sasuke, on the other hand, would be intrigued by this strange girl who seems to know so much about him. He might start to trust her more quickly than he did in the original story, which could lead to a deeper emotional connection between them.
Sasuke might be initially surprised. He is used to the Sakura from his past, so seeing a different, more mature future Sakura could catch him off guard.
In this fanfiction, Sasuke might be shocked to see how much Sakura has changed in the future. Maybe she has become a more powerful ninja, or perhaps she has achieved great things in the medical field, which could make Sasuke view her in a whole new light.
In a Sarada meets past Sasuke fanfiction, it could be that Sarada has to keep her identity a secret at first. She might be on a mission in the past for some reason. As she observes past Sasuke, she could notice his skills and the way he interacts with others, like Naruto. This would give her a chance to understand the bond between her father and Naruto from a whole new perspective, which could be really interesting for the readers.
In this fanfiction, Sasuke might be really nervous when meeting Sakura's parents. He could be worried about making a good impression. Maybe he would bring a small gift, like a flower from his clan's garden.
Well, Itachi might be shocked to see how much Sasuke has changed in the future. Maybe Sasuke has developed new powers or a different outlook on life. Itachi could also feel a sense of pride or regret depending on how Sasuke has turned out.
Another theme is the exchange of knowledge. For instance, a character from the past might have some unique skills or knowledge that is valuable in the future, and vice versa. They then share and learn from each other, like an ancient herbalist teaching future doctors about natural remedies that have been forgotten.
The main characters are Sasuke and Sakura. Sasuke is often depicted as the brooding and talented one, while Sakura is the intelligent and kind - hearted girl.
In this fanfiction, Sasuke and Sakura might have a chance encounter in the high school hallway. Sasuke could be his usual cool self while Sakura might blush seeing him.
