Tenten could also be a good option. She is a fellow ninja and has a practical mindset. She could teach the baby some basic ninja skills as it grows up. And she would be very reliable when it comes to following any instructions left by Neji and Sakura for the baby's care.
Rock Lee might be an interesting choice. He is Neji's friend and has a strong sense of loyalty. He would be very dedicated to taking care of the baby. His physical strength could also be useful in case of any danger. And his positive attitude would be great for the baby's environment.
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.
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.
In fanfiction, Neji and Sakura could form an unlikely alliance against a common foe within the Hidden Leaf Village. This could be due to some political intrigue where they have to trust each other despite their different personalities.
In some Neji and Sakura fanfictions, they might be part of a new team. This team could be facing a powerful new enemy. Neji's calm and strategic thinking combined with Sakura's determination and healing abilities would make for an interesting dynamic. The fanfiction could detail their training together to face this enemy, and how they develop their skills and teamwork.
At first, Sasuke's focus on revenge might make it difficult for him to fully engage with Sakura and Neji. However, as Sakura continues to show her growth in medical ninjutsu and combat, and Neji showcases his mastery of the Byakugan and combat skills, Sasuke might start to open up. Sakura could act as a mediator between the two sometimes. Neji might initially be suspicious of Sasuke's motives but as they face challenges together, he could grow to trust him. And for Sakura, she could develop a deeper bond with both as they all support each other in different ways.
Well, a fanfiction could start with Sakura being in danger during a battle. Neji, being protective and possessive, goes to extreme lengths to save her. He uses his Byakugan to its fullest extent, not caring about his own safety. After the battle, Sakura realizes how much Neji values her and his possessive nature is actually a sign of his deep care for her.
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.
