Well, perhaps in the fanfiction, Naruto and Hinata find out they're having a baby unexpectedly. They then have to deal with the initial shock and excitement. Naruto could be super protective of Hinata right away, making sure she has everything she needs. Hinata might start thinking about how to decorate the nursery in a way that combines their two cultures, Uzumaki and Hyuga. And as the pregnancy progresses, they could share their fears and joys with their friends in the village.
One possible plot could be that Naruto and Hinata are adjusting to their new life as parents. They might face challenges like Naruto's busy Hokage duties and Hinata trying to balance taking care of the baby and her own ninja training. For example, Naruto might miss important baby milestones because of a mission, but Hinata is understanding and they work through it together.
Well, perhaps in this fanfiction, Hinata is forced into a situation by some outside influence, like a villain's mind - control, which makes her act in a way that causes Naruto to cry. After she breaks free from the control, she is filled with regret. She then decides to go on a dangerous mission to retrieve something important to Naruto that was lost during the incident as a way to earn his forgiveness.
Well, one possible plot development could be that Naruto is overjoyed and becomes super protective of Hinata. He might start taking on fewer dangerous missions to be around her more. And Hinata could be dealing with all the hormonal changes while also feeling a bit of pressure as she's now carrying the next generation of the Uzumaki - Hyuga line. There could also be a lot of support from their friends like Sakura, who would be there to help with Hinata's prenatal care.
Perhaps the baby could be named Kazuki. It gives a sense of being strong and noble, which would be fitting for the child of Naruto and Hinata. In fanfiction, the name could also be symbolic of a new beginning or a special power that the baby might possess, like being related to the combination of Naruto's Nine - Tailed Fox power and Hinata's Byakugan abilities.
One possible plot could be that Hinata discovers she's having a baby unexpectedly. This throws her life into chaos as she has to balance her personal life, relationships, and her own growth. Maybe she struggles with how to tell the father, if there is one in the story, and she also has to deal with the reactions of her friends and family.
A possible plot could be that there's a baby monster that is scared of everything in Monsters Inc. Boo, who has experienced the monster world, takes it upon herself to show the baby that there's nothing to be afraid of. She introduces the baby to all the friendly monsters she knows. Sulley and Mike are a bit skeptical at first but soon see how Boo's kindness is helping the baby grow braver. As time goes on, the baby becomes more confident and starts to explore the world on its own with Boo by its side as a guide.
A simple plot could be that Hinata gets injured while on a mission, and Naruto takes it upon himself to nurse her back to health. During this time, they have long conversations and get to know each other on a deeper level, leading to the start of their romantic relationship.
A possible plot could involve Hinata going into early labor. She's scared but tries to be strong for the baby. Naruto is at a crucial point in a diplomatic mission for the village. He has to make a tough choice between staying for the mission's success or leaving immediately for Hinata. In the end, he decides to go to Hinata and with the combined efforts of the medical ninja in the village, they welcome their new baby.
Well, it could be about the baby girl's first steps in ninja training. Maybe she has some unique abilities inherited from both Naruto and Hinata. For example, she might be able to use the Byakugan in a new way that Naruto has influenced, like combining it with his shadow clone jutsu concept.
Their friends would be overjoyed. Sakura would probably be really excited and offer to help Hinata with any medical advice during the pregnancy. Shikamaru might give Naruto some practical advice on how to handle the added responsibilities. Kiba could be really happy and joke around about the new baby being a future ninja partner for his own pups. And Ino would be eager to plan a baby shower for Hinata, full of beautiful flowers and gifts.
