A fanfic might explore Sakura marrying a civilian. She could be attracted to the simplicity and peace that a civilian life offers compared to the chaos of being a shinobi. Sasuke, on the other hand, could marry a rogue shinobi who he tries to reform. This would create a lot of drama as he tries to balance his own values with his new partner's past actions.
Maybe in the fanfic, Sasuke has some personality traits that become more difficult for Sakura to handle over time. For example, his brooding nature might start to feel like emotional unavailability rather than just his usual self. This could lead to her regret.
One possible storyline could be the child's struggle with living up to the legacies of their parents. Sasuke and Sakura are both very powerful ninja, and the child might feel pressured to be just as great. Another could be the child making their own unique mark in the ninja world, perhaps by developing a new jutsu or forging new alliances.
In some fanfictions, Sasuke might be in a situation where he has to choose between his goals and Sakura. His choice could end up hurting her. For instance, he decides to go on a very dangerous mission alone, knowing that Sakura is deeply in love with him and would be worried sick. His disregard for her feelings in this case is a form of emotional hurt. Also, there could be a scenario where Sasuke is forced to fight against Sakura in a misunderstanding, and his superior skills end up causing her serious injuries.
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.
A different story could be them traveling the world together. They visit different villages and learn about new cultures and techniques. Along the way, they meet old friends and foes. This journey would strengthen their bond as they rely on each other for support and protection in unfamiliar places.
A fanfic could be centered around an alternate universe where Madara never turned evil. He and Sakura are both part of the same ninja team. Sakura, with her medical ninjutsu skills, often has to patch up Madara after their tough missions. Over time, Madara starts to respect Sakura not just for her healing abilities but also for her strong will. Sakura, on the other hand, sees a different side of Madara that is not known to many. Their relationship gradually evolves from teammates to close friends and perhaps something more as they face different challenges together in the ninja world.
One possible storyline could be that Sakura realizes Sasuke is too consumed by his revenge and she decides to focus on herself. She might start training harder to become a better ninja in her own right, perhaps specializing in medical ninjutsu even more. This could lead to her making new friends and allies within the village, and she could end up being a key figure in Konoha's development, without Sasuke in the picture.
In this fanfiction, it could be that Sasuke returns to the village and he and Sakura start to build a life together. Their friends are happy for them, and then Sakura becomes pregnant. The story might explore how the news affects their friends and family, and also how Sasuke and Sakura grow as a couple during this time.
One popular storyline could be their post - war life together. They might be shown building a family, with Sasuke learning to be more present in the family after his long absences. Another could be Sakura using her medical skills to help Sasuke with any lingering injuries from his battles. There could also be a story where they go on adventures together, facing new threats to the ninja world side by side.
Another storyline might be that Lemon is a person. Let's say Lemon is a new character who has some sort of connection to the Uchiha clan. She could be a long - lost relative or someone with a prophecy related to Itachi and Sasuke. And Sakura gets involved as she is part of Team 7. The story would then be about uncovering Lemon's true identity and purpose.
