Firstly, Sasuke would be deeply hurt. He might see it as a sign of his own unworthiness. Naruto, who has always been empathetic, would try to make sure Sasuke doesn't go down a dark path again. As for Sakura, she would be starting a new chapter with Naruto. Their relationship would be under a lot of scrutiny. The village that once hoped for Sasuke and Sakura's union would now have to adjust to this new situation. And Naruto would have to be strong enough to protect Sakura from any threats that might come from Sasuke's side if he turns vengeful.
The dynamic would be turned upside down. Sasuke would likely become more of an outcast or a loner, feeling rejected. Naruto would be in a difficult position, having to balance his friendship with Sasuke and his new relationship with Sakura. Sakura would be the catalyst for this change, and she would have to face the consequences of her actions, like dealing with the villagers' opinions and the potential backlash from Sasuke's supporters.
Naruto might initially be in denial. He's so used to having Sakura around and believing that they have a future together. So when she leaves for Sasuke, he might think it's just a temporary thing or that she's been influenced by something or someone. But as time passes and he realizes it's real, he would be deeply hurt. He might also start to question his own self - worth, thinking that he wasn't good enough for Sakura. And he might even try to win her back at first, but then slowly come to accept the situation and focus on his other responsibilities like being a ninja and protecting the village.
Well, it makes the triangle less of a love triangle. With Naruto out of the picture in terms of caring for Sakura, it becomes more about Sakura and Sasuke's relationship without Naruto's interference. Sasuke may not have to deal with Naruto's rivalry in terms of Sakura's affection anymore.
She could be heartbroken. Sakura has always loved Sasuke deeply, so his leaving for Naruto would be a huge blow to her. She might initially be in denial, not believing that Sasuke would choose Naruto over her.
The story's dynamic would change significantly. For one, Naruto might be more confident and happy. Since he has feelings for Sakura, having her love in return would boost his morale. And their interactions would become more affectionate and less one - sided like in the original where Sakura was mainly focused on Sasuke.
One possible reason could be her long - standing and deep - rooted love for Sasuke. Since childhood, she has had strong feelings for him. Maybe in this fanfiction, she realizes that her feelings for Sasuke are unshakable and that she can't continue to be with Naruto while having such intense feelings for another.
Naruto and Sasuke's relationship might become more complex. On one hand, they are in a new and dangerous environment together, which could strengthen their bond as they rely on each other. But on the other hand, the ideology of Akatsuki might put some strain on their relationship if they have different views on how to handle the situation within the organization. For example, Sasuke might be more inclined to use force while Naruto tries to find a more diplomatic solution.
Well, Naruto has a very warm and persistent personality. He's always there for his friends, and he has a big heart. In fanfiction, Sakura might see these qualities in Naruto and realize his true value. He's the kind of person who can make her laugh and feel safe, which could be very appealing compared to Sasuke's more brooding nature.
Naruto and Sasuke's relationship would likely become more stable. They would have to put aside their old rivalries for the sake of the 'family'. They might start to see each other as brothers - in - law in a sense. Sakura would be the bridge between them, her love for both of them in different ways helping to ease any remaining tensions. Naruto would probably become more protective of Sasuke, and Sasuke would be more open to Naruto's friendship.
Yes, there are many such fanfictions. In some of them, Naruto and Sasuke realize Sakura's deep love over time. For example, in certain stories, after going through numerous battles and hardships together, they see Sakura's unwavering support and love. This makes them re - evaluate their feelings towards her and gradually accept her love in a very heart - warming way.
Their relationship would likely become more intimate and committed. With a baby on the way, Sasuke would feel a greater sense of responsibility towards Sakura. He might be more protective and stay closer to her.
