Another plot could be set in an alternate universe where Sasuke never left the village in the first place. He and Sakura grow up together, train together, and their friendship slowly turns into love. They get married in the village and the fanfic could detail their wedding night and subsequent loving relationship, including the act of making love as a natural part of their married life.
One possible plotline could be that after Sasuke has finally returned to the village and reconciled with Sakura, they start to rebuild their relationship. They go on dates, share their feelings and experiences during their time apart, and gradually their love deepens until they reach a point of expressing their physical love for each other.
Perhaps Sasuke uses Sakura to get closer to some information. He might know that Sakura has connections or knowledge that can help him in his quest for revenge or for protecting the village. So he uses her in a strategic way while she is initially unaware of his motives. As the story progresses, their relationship could develop in complex ways.
Maybe Sakura teaches Sasuke about emotional control. Sasuke has always been brooding and angry, and Sakura, with her more empathetic nature, could show him how to manage his emotions better. This could lead to Sasuke becoming a more well - rounded ninja and a better teammate.
Maybe Sasuke is jealous because Sakura has achieved some great feat in the ninja world and is getting a lot of attention. In the fanfic, this could lead to Sasuke training even harder to prove himself worthy of her. Sakura, on the other hand, might be confused by Sasuke's sudden distance. She could try to reach out to him, but Sasuke's pride and jealousy keep him from being receptive. It could all come to a head during a dangerous encounter with a powerful enemy where they finally communicate their feelings.
One possible plotline could be that Sasuke, feeling conflicted by his past and the secrets he holds, distances himself from Sakura and starts to develop an inappropriate emotional connection with someone else, which Sakura misinterprets as cheating. As for Itachi's role, perhaps his memories or the influence he had on Sasuke play into Sasuke's actions, like Sasuke trying to live up to some ideal Itachi had that made him question his relationship with Sakura.
One possible plotline could be Sasuke becoming increasingly possessive as Sakura's popularity or friendships grow. He might start to isolate her from others, thinking it's for her own good.
A possible plotline could be that Sakura discovers she has a rare and dangerous pregnancy complication. Sasuke, initially shocked, vows to protect her and find a solution. He might go on a journey to find a rare herb or seek the help of a reclusive healer. Meanwhile, Sakura is in the village, trying to stay strong and use her medical skills to keep herself and the baby alive as long as possible.
Sasuke could initially be a vampire who is full of anger and resentment, maybe because of how he was turned. But Sakura's positive attitude and kindness could start to soften him. He might start to open up about his past and his feelings. Sakura could develop from a somewhat naive vampire into a more worldly and wise one. She would learn about the darker side of the vampire world through Sasuke, and this would change her. Maybe she would become more cynical at first, but then find a balance between her old self and the new knowledge she has gained.
For Sakura, she could grow in terms of her leadership skills. If they encounter any difficulties in the forest like being chased by a group of wild animals or getting caught in a dangerous situation, she could step up and lead the way out. Sasuke might then realize that Sakura has the potential to be a great leader. And for Sasuke himself, he could become more open to the idea of a relationship with Sakura. The seclusion of the forest could provide the perfect backdrop for him to explore his feelings for her.
A plotline might involve Sakura facing a lot of judgment from the village. But she stands strong and raises the child with the help of her friends like Naruto and Ino. They support her emotionally and sometimes even materially. As for Sasuke, he might be on a journey of self - discovery and when he hears about the pregnancy, he has to decide whether his path still lies away from Konoha and his family or if he should change his ways.
Another plotline could be that a new threat emerges in the ninja world that specifically targets the Uchiha clan. Sasuke, Sakura and Sarada have to work together to protect their family and the village. This would not only show their family bond but also their loyalty to their home. There could be intense battles and emotional moments as they face this new danger.
