Well, one possible plot development could be that Naruto's hatred for Sakura creates a lot of tension in the story. Maybe it leads to some kind of rivalry where they constantly compete in missions or training. And Sakura's love could be unrequited at first, causing her to strive harder to prove herself to Naruto. Another development could be that the fanfiction explores the reasons behind Naruto's hatred, like some past misunderstandings that need to be resolved for them to have a normal relationship.
Perhaps in this fanfiction, Naruto's hatred for Sakura is a cover - up for some deeper emotions he doesn't want to admit. Sakura's love, on the other hand, might be the driving force that eventually breaks through Naruto's facade. The plot could develop as Sakura tries different ways to get closer to Naruto, while Naruto struggles with his internal conflict of hating her but also being drawn to her in some way.
For Naruto, his character arc could start with his intense hatred for Sakura. As the fanfiction progresses, he might start to question his feelings. Maybe he realizes that his hatred was misdirected or based on false assumptions. For Sakura, her arc could be about persevering in her love despite Naruto's hatred. She could grow stronger and more confident in expressing her feelings and trying to change Naruto's view of her.
In fanfiction, the evidence often lies in the way the author portrays Naruto's interactions. For example, Naruto may be shown being cold or dismissive towards Sakura, like avoiding her company or not showing any romantic interest. Meanwhile, with Hinata, he could be depicted as being more affectionate, like blushing around her or always coming to her aid. But it's important to note that this is all in the realm of fan - created interpretations and not the official canon.
The plot could develop with Naruto trying to distance himself from Aphrodite and her influence. He might start to explore other aspects of his ninja heritage to counteract what he sees as her negative influence. For example, he could focus more on training with his ninja teachers who uphold the traditional values of the village.
One common plot device is the love triangle. It creates drama as Sakura may be jealous of Hinata's relationship with Naruto. Another is the redemption arc for Naruto's feelings. Maybe he used to be confused about his feelings for Sakura but then realizes his true love is Hinata. And there could be a friendship break - up plot device where Naruto distances himself from Sakura due to his newfound love for Hinata.
Another development could be that Sakura starts to develop feelings for Naruto as she spends more time thinking about his love for her. She might notice things about him that she never paid attention to before, like his kindness and determination in a more romantic way.
One possible plot could be that Naruto discovers Mimikyu in the Hidden Leaf Village. He's initially confused by this strange Pokémon but quickly grows fond of it because of its shy and somewhat mysterious nature. Naruto might see a bit of himself in Mimikyu, as they both have aspects that are not fully understood by others at first.
For Naruto, he might develop better understanding of the girls' abilities. For example, he could learn more about Ino's mental communication skills and Sakura's growing medical and combat skills. This could make him more reliant on them in different situations.
For Naruto, he could develop more in terms of his leadership skills. In fanfiction, he might learn to be more diplomatic when dealing with the different clans in Konoha, especially when working with Hinata's Hyuga clan. He would become more of a unifying figure, not just a powerful ninja.
Perhaps in this fanfiction's universe, Naruto's goals and ideals are completely different from Kakashi and Sakura's. Naruto may be aiming for a more radical change in the ninja world, while Kakashi and Sakura are more conservative. Their differences could lead to Naruto developing a sense of hatred towards them as they constantly oppose his ideas.
Perhaps Sakura gets into trouble during a training exercise and Itachi has to rescue her, which then leads to a more intense and focused training regime. Another development could be that Sakura starts to think like Itachi in battle situations, using his tactics to outwit her opponents. It could also be that as she gets stronger, other characters start to notice and either become jealous or try to recruit her for their own purposes.
