Perhaps Naruto sees Ino's growth potential more clearly. Ino has been working hard to improve herself, and Naruto might recognize that. In contrast, Sakura's focus on Sasuke sometimes overshadows her own growth. Naruto might choose Ino because he wants to support someone who is more focused on their own self - improvement and is also able to contribute more effectively to the team.
Perhaps Sakura is jealous because of her own insecurities. She might be comparing herself to both Naruto and Ino. Naruto has his own charm and strength, and Ino has her grace and popularity. Sakura, who might be struggling with her own self - worth, could see their interactions and feel envious, thinking that they are better off without her or that they have something she doesn't.
One reason could be their long - standing feelings for Naruto. They both care about him deeply, and in fanfiction, this can lead to intense rivalry. Sakura may feel that she has known Naruto longer and has a stronger claim. Hinata, on the other hand, has her own deep, unspoken love for Naruto that she might be more willing to fight for. Another reason could be their own insecurities. Sakura might be insecure about Hinata's gentle and kind nature that Naruto seems to like. Hinata could be insecure about Sakura's strength and her history with Naruto.
One reason could be for the sake of creating drama. Writers often use such plot twists to make the story more interesting. If Ino is in a relationship in the fanfiction, cheating can add a lot of conflict.
One possible reason could be Hinata's unwavering loyalty. Throughout the series, Hinata has always been there for Naruto, believing in him even when others didn't. In contrast, Sakura was often more focused on Sasuke. So Naruto might see Hinata as someone who truly understands and supports him.
Sakura might cry over Sasuke because of the distance between them. In many fanfictions, Sasuke goes off on his own journey, leaving Sakura behind. She misses him and the pain of separation makes her cry. Additionally, if Sasuke gets injured severely in a fight, Sakura, being a medic, might cry out of worry for his well - being and the possibility of losing him.
In a fanfiction, Sakura and Ino fighting over Naruto could lead to some intense verbal exchanges. Maybe Sakura would bring up how she has been on more missions with Naruto, while Ino might counter with how she has a deeper understanding of Naruto's emotional side. It could also involve some petty rivalries like competing over who gets to sit next to Naruto during team meetings in the fan - made story.
Jealousy could be a major challenge. Sakura and Ino have had a bit of a rivalry in the past, so sharing Naruto might bring back some of those feelings. Also, the social norms of the village might be against such a non - traditional marriage, which could lead to them facing discrimination or at least strange looks from the villagers.
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.
One reason could be that Naruto has always been more attracted to those who understand his outcast past better. Sakura doesn't really have that kind of connection with him as she comes from a more normal background. So there's a lack of that fundamental understanding between them which hinders any romantic feelings.
One reason could be jealousy. If in the fanfic, Sakura gets closer to someone else Naruto cares about, like Sasuke in a different way than he expected, it might make him hate her. For example, if Sakura teams up with Sasuke against Naruto's wishes in the fan - created plot.
