The younger generation of ninja like Boruto and his friends, if they were to somehow be involved in this situation (maybe in a time - travel or AU fanfic), would be very confused. Boruto especially might have a hard time imagining his father in this kind of romantic situation. They might try to interfere in a well - meaning but clumsy way, thinking they know what's best for Naruto and Sakura.
Sasuke would probably be quite surprised. He might initially be a bit skeptical about Sakura's feelings, thinking it could be some sort of impulse. Shikamaru, being the perceptive one, would likely see the potential for chaos in this new development. He might try to stay out of it at first but keep an eye on how things unfold. Choji would be more focused on the emotional aspect and would hope that Naruto and Sakura can work things out happily.
However, in other cases, Naruto could be hesitant. He might have grown so used to their friendship that the idea of a romantic relationship with Sakura is a bit overwhelming. He could take a step back and say something like 'Sakura, this is really unexpected. I need some time to think about this.' This would then lead to a more complex exploration of their relationship in the fanfiction.
Sasuke might initially be a bit aloof but secretly be happy for them. He's always had a complex relationship with Naruto and Sakura, and deep down, he would see that they are good for each other.
Kakashi would be more of a supportive figure. He has seen Naruto and Sakura grow up, and he would likely be happy for them. He might offer some advice to Naruto on how to handle this new relationship, especially considering the challenges they might face as ninjas. For Sakura, he could give her words of encouragement to be true to her feelings.
Their friends would be overjoyed. Kakashi would probably be like a cool uncle, always ready with some wise advice for the new parents. Shikamaru might be a bit exasperated at Naruto's over - enthusiasm as a father, but still be happy for them. Ino would be excited to spoil the baby with cute outfits and toys, and Choji would bring over lots of delicious snacks for the new family to enjoy.
Sasuke would probably have a complex reaction. He might feel a bit of envy deep down but also be happy for them on the surface. Kakashi would be very supportive and would likely give them some sage advice about marriage, like how to always communicate and trust each other. Shikamaru would be like 'What a drag, but congratulations anyway' in his typical laid - back style.
Sakura might initially be confused. She has known Naruto for a long time and his sudden coldness would be unexpected. She may try to reach out to him to find out what's wrong.
Sakura might be really surprised at first. She could offer to help Naruto with his girl disguise, teaching him things like how to do his hair or choose the right clothes. She might also find it a bit funny but would be supportive in the end, seeing it as part of a mission. Sasuke, on the other hand, might be a bit more aloof. He would probably just raise an eyebrow at Naruto's new look but wouldn't make a big fuss about it as long as it was for a good reason.
His friends would likely be shocked. Shikamaru, for example, would probably be disappointed in Sakura. He might try to comfort Naruto and tell him to think rationally. Choji might be angry on Naruto's behalf and want to confront Sakura. And Sasuke, if he's around, might have a complex reaction. He might feel a strange sense of satisfaction that Naruto is finally seeing Sakura's 'true' side, but also a bit of pity for Naruto.
She may feel angry at first. Sakura is a strong - willed character. She might think that Naruto has made this decision without considering her feelings. In the fanfic, she could go on a rant about how he should have talked to her before making such a big decision.
At first, Naruto would likely be extremely shocked. He has always considered Sakura a friend and teammate, so this would be a huge blow. He might question his own judgment in trusting her.
