A more emotional plot could be centered around family. Sarada has some doubts about her family, and Naruto and Sakura, having been through their own family - related struggles, could offer her advice and support. They could share their stories of growing up without parents (in Naruto's case) or with a complex family situation (in Sakura's case), which would help Sarada come to terms with her own family issues.
One idea could be a time - travel plot where Boruto and Sarada are sent back to Naruto and Sakura's genin days. They could witness the early days of Team 7 and get involved in some of their missions, which would change the course of history in unexpected ways.
One plot idea could be Sarada trying to learn more about her father Sasuke's past adventures. She could ask Sakura for stories, and together they could go on a small journey to a place important to Sasuke's past. This would strengthen their family bond.
Maybe a story where an enemy targets Sarada to get to Naruto and Sakura. Naruto and Sakura then have to put aside all their differences and past issues to protect their daughter. This could involve flashbacks to their own relationship history and how they overcame obstacles in the past. It could also show Sarada realizing the depth of her parents' love for each other and for her.
One plot idea could be Sarada discovers an old diary of Sakura's from her early days as a ninja. This could lead to Sarada learning more about her mother's past struggles and achievements, strengthening their bond. Another idea is that they go on a joint mission together where Sakura teaches Sarada some advanced medical ninjutsu skills. A third could be a story where Sarada gets into trouble and Sakura has to use her wisdom and strength to save her, and through this experience, Sarada gains a newfound respect for her mother.
One plot idea could be Sakura teaching Sarada some of her own medical ninjutsu skills. Sarada, being eager to learn, would face challenges in mastering the complex techniques but with Sakura's patient guidance, she would gradually improve. Another idea is Sakura taking Sarada on a mission to a far - off village. Along the way, they encounter various difficulties that test their relationship and skills. This would also be a chance for Sarada to see her mother in action in a different environment.
One idea could be a time - travel fanfiction where Boruto and Sarada end up in the past and meet Naruto and Sakura during their early days. They could help change some small events that have a big impact on the future.
One idea could be a time - travel plot where Boruto and Sarada are sent back to Naruto's era. They could interact with a younger Naruto and help him in some way that changes the future subtly. For example, they might help Naruto with a difficult mission that he barely survived in the original timeline, and this could lead to different relationships in the future.
Perhaps a fanfic where Sakura and Futa are old friends, and Sarada is initially suspicious of Futa. But as the story progresses, they all learn from each other. For example, Futa teaches Sarada some unconventional fighting techniques, while Sakura imparts her medical ninjutsu knowledge to Futa.
Another idea is that there is a prophecy about the two of them saving the village from a great threat. They initially don't believe it, but as strange events start to occur, they begin to accept their fate and train hard to be able to face the oncoming danger.
One idea could be exploring how Sasuke and Sakura adjust to the impending parenthood while also dealing with their ninja duties. Maybe Sasuke is away on a mission and Sakura has to handle the pregnancy alone for a while, which makes her stronger and more independent.
