Perhaps the story could start with Hinata revealing her pregnancy to Neji. Neji is initially shocked but then quickly embraces the idea of being an important figure in the child's life. As the pregnancy progresses, they face challenges like Hinata's health issues due to her delicate state. Neji uses his skills and knowledge to find remedies and support her. They also plan for the future of the baby, thinking about what kind of ninja the child will become.
Maybe in the fanfic, they are on a mission together when Tenten realizes she's pregnant. This throws them off their game a bit as they now have to worry about the baby's safety too. They return to the village and Neji tells their friends, who are all excited and offer support. As Tenten's pregnancy progresses, they face some challenges like Tenten having morning sickness and Neji trying to balance his duties and taking care of her.
The antagonists could be some members of their own clan who oppose the union or the pregnancy for various reasons, such as concerns about bloodline purity or political power within the clan. They might try to undermine Neji and Hinata's relationship and the pregnancy.
Maybe there's a powerful enemy who has the ability to make people transform. Naruto gets hit and turns into Hinata and Neji. As Hinata, he tries to use her gentle fist techniques and discovers new aspects of combat. As Neji, he might get into debates with his own Naruto - self in his mind, as Neji had different views on things like destiny. This could lead to Naruto re - evaluating his own beliefs.
One idea could be a story where Hinata discovers she's pregnant and is initially scared. Neji, being her protective cousin, steps in to support her. He could help her prepare for the baby by training her gently to keep her healthy during pregnancy. Another aspect could be how the rest of the clan reacts to the news. Some might be overjoyed while others may worry about Hinata's ability to still be a strong ninja.
One possible plot could be a forbidden love story. Since they are from the same clan, there might be some clan rules against their relationship. So they have to keep their feelings a secret until they can't hold back anymore and share a kiss. Another plot could be that Hinata is in danger and Neji saves her, and the relief and pent - up emotions lead to a kiss.
One possible plot could be that Naruto and Hinata find out about the pregnancy and they are both overjoyed. They start preparing for the baby's arrival, with Naruto being super protective of Hinata. He might go on missions less often to be around her. Hinata, on the other hand, could be seen knitting baby clothes and daydreaming about their future family life.
Well, perhaps in the fanfic, Naruto is away on a mission when Hinata discovers she's pregnant. She then has to deal with the initial shock and excitement all by herself. But she's strong, and she starts taking care of herself and the unborn baby. When Naruto returns, he's overjoyed and vows to protect his family even more fiercely. And they could have a little ceremony in the village to celebrate the upcoming addition to their family.
Another plot could be that they discover their pregnancies around the same time and decide to support each other in their respective journeys. They might share their fears and hopes, like Hinata being worried about how her child will fit into the Hyuga clan's strict hierarchy and Neji being concerned about providing a good future for his child. They could then work together to change some of the old ways in the clan for the betterment of their future children.
One possible plot could be that Hinata is somehow mind - controlled. Maybe an enemy uses a powerful genjutsu on her that makes her see Neji as a threat to Naruto or to the village. Under this influence, she attacks and kills Neji, which then leads to a great deal of guilt and self - loathing for Hinata once she breaks free from the control.
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.
