In some fanfictions, there are special abilities or bonds that enhance their understanding. Maybe a magical connection that allows them to feel each other's emotions. This makes it easier for them to know what the other is thinking or feeling at any given moment. So, when one is in danger or has a strong emotion, the other can sense it and respond accordingly, deepening their understanding of one another.
Sakura would be completely devastated. She's been in love with Sasuke for so long and has a deep bond with Naruto too. She might go into a deep depression and lose her will to be a ninja for a while.
Well, in a lot of fanfiction, their love for each other is depicted as a soul - deep connection. They understand each other on a level that no one else does. Their relationship might be shown with a lot of emotional moments. Like when they reunite after a long time apart, there are intense feelings of relief and joy. Also, some fanfics may explore a more romantic side of their relationship, with tender glances and gentle touches.
Sakura would be devastated. She has always had deep feelings for Sasuke. She might initially be angry with Naruto, thinking that there could have been another way. But later, she might understand Naruto's difficult decision when she realizes the threat Sasuke posed.
The Hidden Leaf villagers would be shocked. They see Akatsuki as the enemy, so they would think Naruto and Sasuke have betrayed them. Kakashi would probably be very concerned and try to find out their reasons. Sakura would be heartbroken and might even try to go after them to bring them back. As for the Akatsuki members themselves, some might be suspicious of Naruto and Sasuke's motives at first, while others might see it as an opportunity to use their power for Akatsuki's goals.
Common themes include the idea of unconditional love. Naruto loves Sasuke regardless of what he does. There's also the theme of forgiveness. Sasuke has to forgive Naruto for some things, and vice versa. And a lot of fanfics play with the theme of destiny, as if they are meant to be together in some way, whether it's as friends or something more romantic.
Sakura would be devastated. She has deep feelings for both Naruto and Sasuke. She would probably be angry at Sasuke for killing Naruto and at the same time feel guilty for not being able to stop it. She might even try to take revenge on Sasuke.
Naruto would be deeply saddened. He has always hoped for Sasuke and Sakura to be happy together. He might initially try to mediate and get them to work things out, believing that their relationship can be salvaged. He would remind them of the good times and how much they mean to each other.
One way it could be developed is through a series of challenges that test their bond. For example, they could face a powerful enemy together. Naruto's determination, Sasuke's skill, and Sakura's medical abilities would all contribute to their victory. This shared experience would strengthen their love for each other.
Another moment might be when they save each other's lives. For instance, if Naruto risks his life to protect Sasuke from a powerful enemy. This act of self - sacrifice shows Sasuke how much Naruto truly cares about him, and it makes Sasuke start to see Naruto in a new light, thus deepening his understanding of Naruto. And vice versa, when Sasuke saves Naruto, it also has a similar effect.
