What could be the plot in a fanfiction where Sakura and Neji are siblings?

Perhaps there's a mission where Neji and Sakura are teamed up and during that mission, something magical or strange happens that results in Sakura's pregnancy. Neji, who has always been a bit reserved, is now forced to confront his feelings not only for Sakura but also for the future of their unborn child. Sakura has to deal with the physical and emotional changes of pregnancy while still being a ninja. As the story progresses, they might find support in unexpected places, like some of the older ninja who have been through similar situations. And they'll have to navigate the complex world of the ninja villages while also preparing for their new family life.

Well, it could be a story set in a post - war era. Sakura is now a highly respected medical ninja, and Neji has become an important figure in the Hidden Leaf Village. They are brought together by a mysterious illness that is affecting some of the villagers. As they work together to find a cure, they spend a lot of time in close proximity. The fanfiction might explore their emotional and physical attraction during this time. Maybe there are some tender moments where they share their past traumas and hopes for the future, and their relationship blossoms in this unique situation.

One possible plot could be that Neji and Sakura are friends who end up taking care of a baby together. Maybe they find the baby during a mission in a village that has been attacked. They then have to figure out how to keep the baby safe and fed while also continuing their ninja duties. Neji could use his Byakugan to sense any danger approaching the baby, and Sakura could use her medical skills to make sure the baby is healthy.

They would become more protective of each other. Neji, being the older (or at least more experienced) one, would likely feel a sense of responsibility for Sakura. Sakura would look up to Neji and his skills. For example, in a fight, Neji would instinctively move to shield Sakura from harm, and Sakura would do whatever she could to support Neji, like healing his injuries immediately.

Another possibility is that they are rivals in a friendly way. They could constantly compete to see who can improve faster in different aspects such as medical ninjutsu (for Sakura) and Byakugan - related skills (for Neji). This rivalry could push them both to reach new heights in their respective skills and at the same time, deepen their respect for each other.

Maybe there's a plot twist where Sakura discovers that Neji was forced into the arranged marriage against his will. This could lead to her trying to find a way to break the arrangement in a way that doesn't cause too much trouble for their families or clans. However, in the process, they start to develop real feelings for each other.

Maybe the fanfic is set in a post - war scenario. Their team is tasked with rebuilding relations with a neighboring village. Sakura uses her charm and diplomacy skills, which she has developed over time. Neji, with his respected status, helps in negotiations. Shikamaru, being the brains, figures out the best ways to trade and cooperate. There could be some resistance from within their own village and from the other village, but they persevere.

One plot idea could be a story where Sakura and Neji are paired on a mission in a foreign land. They have to rely on each other's skills to survive and in the process, they discover new aspects of each other's personalities. For example, Sakura's medical skills might save Neji from a deadly poison, and Neji's Byakugan helps them avoid hidden traps.

Well, it could be a story about their academic competition. Maybe they are both top students vying for the best grades in school. Sakura could be really good at biology while Neji excels in math. They start off as rivals but gradually come to respect each other's skills and form an unlikely friendship.

One possible fanfiction could be about Neji and Sakura going on a mission together. In this story, they might start off as just comrades but gradually develop a deeper understanding of each other. Neji's calm and composed nature could contrast with Sakura's more fiery and determined personality, leading to some interesting interactions.
