Edward could develop more patience. As Bella trains, he may have to learn to let her take risks and grow on her own, instead of always being overprotective.
They could both develop a deeper understanding of each other's worlds. Bella gets to see the vampire side of things more closely during her training, and Edward gets to see Bella's determination and courage in a new light. This could strengthen their bond in ways that go beyond just their romantic relationship.
A plot could involve Bella training in some ancient vampire magic that Edward doesn't know about. It could be a way for her to assert her independence and also help in the fight against their common enemies.
Their relationship could develop as they start to respect each other's skills more. As they train, they see the hard work and determination in each other, which makes them put aside their past grudges. For example, when Naruto manages to dodge one of Sasuke's powerful attacks, Sasuke realizes that Naruto has truly become stronger. This makes him more open to working with Naruto rather than against him.
At first, their relationship would likely be formal, with Genma as the strict trainer and Sakura as the eager student. But as time goes on, Sakura's determination and progress might earn Genma's respect, and he could become more of a mentor to her. For example, he might start sharing his own experiences with her to help her understand the importance of the training.
Bella often becomes more confident in her relationship with Edward as his wife. She may be more assertive in making decisions for their future together.
In fanfiction, King Edward might start as a rather aloof character and gradually open up to Bella. His character development could involve learning to trust and rely on her more.
Well, in the 3 - year training fanfiction, Naruto could also have some intense mental growth. He might learn more about the history of his clan and the ninja world from Jiraiya. This knowledge would not only make him a better ninja but also shape his understanding of his place in the world and his responsibilities.
It often starts with attraction. Edward is drawn to Bella's unique scent and her differentness. Bella, on the other hand, is intrigued by Edward's mysterious nature.
Their relationship can develop as they rely on each other during training. For example, Naruto might start to see Hinata in a new light when she saves him from a tricky training situation using her skills. This newfound respect can be the start of deeper feelings.
At first, their relationship might be one of pity on Bella's part. She sees Edward as someone in need and wants to help. But as they spend more time together, old feelings start to resurface. Edward may be hesitant at first, being in a vulnerable homeless state, but Bella's kindness slowly breaks down his barriers.
Their relationship might develop slowly at first. Since Edward is older, he could be more cautious. He might take his time getting to know Bella on a deeper level before fully committing to a relationship.
