He could be a bit jealous. Boruto has his own relationship with Sasuke as his mentor, and if Sarada is so interested in fanfiction about Sasuke, Boruto might feel like she's encroaching on his territory in a way. However, he would probably be too proud to admit it right away.
Some fans might be outraged. Naruto is a beloved character, and the idea of him being cheated on by Boruto goes against the positive father - son relationship they expect. They would see it as a distortion of the characters' true natures.
Sakura would be protective of Sarada. She would want to make sure that Boruto has good intentions. She might initially be a bit against the relationship but would come around once she sees how much they care for each other. Shikamaru, being the smart strategist, would see this as a potential distraction for both of them. He would try to give them advice on how to balance their relationship and their ninja duties.
Well, Boruto might feel a sense of pride seeing his father Naruto in action against Sasuke. He has heard so many stories about their battles, and now seeing it in a fanfiction version could make him realize the deep bond and rivalry between them. He might also analyze their fighting styles and try to incorporate some of their moves into his own combat techniques later on.
Boruto might be in awe. He could see his father in a new light, understanding the struggles and growth Naruto went through. It might also inspire Boruto to better himself and live up to his father's legacy.
No, Boruto is alive in the manga. The plot hasn't led to his death. However, the manga is ongoing, and anything could happen in the later developments.
Yes, Boruto is indeed a manga. It expands on the Naruto universe and offers fresh perspectives and storylines. Many fans enjoy reading it to delve deeper into the world created by the series.
Naruto would be devastated. He might blame himself for not being able to protect his son. Sasuke would be angry and would likely go on a hunt for the perpetrator. His friends like Sarada and Mitsuki would be heartbroken. Sarada might vow to become stronger to prevent such a tragedy from happening again.
