He may initially be too stunned to fight back. But as the situation progresses, if Sakura continues to attack, Naruto might start to defend himself while still trying to understand why she is so angry. He could also feel a bit of sadness because he values their friendship and doesn't understand why she is acting this way. Naruto might even start to think that he has done something truly unforgivable without realizing it.
Naruto might be shocked at first. He has always seen Sakura as a friend, so being beaten up by her would be unexpected. He could try to talk to her and figure out what's wrong.
At first, Naruto might be extremely shocked. He trusts Sakura as a teammate and friend, so being kidnapped by her would be completely unexpected. He would likely try to talk to her, asking her why she's doing this.
Sasuke could be one. Given their complex relationship, there could be a situation where Sasuke's newfound power or different ideology leads him to fight and beat Naruto in a fan - made story.
At first, Naruto may be heartbroken and confused as to why he is being bullied. He might cry in private, but in public, he tries to put on a brave face. As time goes on, he realizes that he can't let the bullies control his life. So, he tries to find friends who will support him, like Shikamaru or Choji. With their help, he begins to stand up to the bullies more effectively and also works on building his own self - confidence.
It could lead to a shift in the type of fanfictions being produced. If Naruto getting fed up with Sakura fanfiction becomes a popular concept, more fanfic writers might avoid writing in that vein or might try to rewrite the relationship in a more acceptable way, which in turn changes the overall landscape of Naruto fanfictions in the fandom.
Naruto would be angry. He's not the type to just accept being kidnapped. He'd immediately start looking for ways to escape. He might try to use his ninja skills to break free from whatever restraints Orochimaru has put on him.
Naruto might be very forgiving right away. He has always had a big heart and cared deeply for Sakura, so he could just accept the apology with a big grin and say it's all in the past.
Naruto could also feel a deep sense of hurt. After all, he has been through a lot with Sakura. In the face of her betrayal, he might start to question his own judgment of people. However, being Naruto, he would not give up easily. He might try to find a way to redeem Sakura or at least make her see the error of her ways. He would draw on his own experiences of being ostracized in the past and use that to try to understand her actions and find a solution.
Well, Naruto is a really perceptive guy deep down. If Sakura pretends to love him in fanfiction, at first he might be super excited. He'd probably start thinking about all the things they could do together, like going on dates to Ichiraku's. However, Naruto also values honesty a great deal. Once he starts to suspect that Sakura's love isn't real, he would likely confront her. He might say something like 'Sakura - chan, I feel like there's something not right. You can tell me the truth.' And depending on how Sakura responds, Naruto could either be really sad and withdraw a bit, or he could try to figure out why she's pretending and help her if there's a deeper issue.
She might be heartbroken. Sakura could initially be in shock and then fall into a deep sadness. She may blame herself for Naruto's leaving, thinking that she could have done something differently.
I think Naruto would be heartbroken. He's always been so open and sincere in his feelings. When he discovers Ino has cheated on him, he might go on a bit of a self - discovery journey. He'd wonder what he did wrong, even if it wasn't his fault at all. He could also become a bit more cynical about love, which would be a big change for him. He might start to see the world in a different light and be more guarded in future relationships.
