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.
It could mean that Sarada is trying to understand her father better. Fanfiction often explores different aspects of a character's personality. By reading Sasuke fanfiction, Sarada might be looking for insights into Sasuke's past, his motives, and his relationships. It could also be a way for her to connect with other fans' interpretations of her father, which might influence her own view of him.
In fanfiction, the idea of Boruto and Sarada getting married is quite popular. Many fans like to explore this relationship because they have a unique bond in the Naruto universe. Their personalities, with Boruto being adventurous and Sarada being determined, could make for an interesting married couple in fan - created stories.
As of now, no. In the Boruto series, their relationship is mainly focused on their friendship and comradeship as ninja. There are some moments that fans might interpret as having a hint of something more, but the story has not made their relationship a romantic one in an official capacity.
I really like the fanfic 'Sarada's Ascent'. It shows Sarada facing various challenges in the Hidden Leaf Village. The author does a great job of portraying her determination and growth, making it an exciting read for any Boruto fan.
There may be some well - known fanfics with Boruto and Sarada kissing, but it really depends on which fanfic communities you explore. Some smaller, niche communities might have a fan - favorite that isn't as well - known in the larger Naruto/Boruto fanfic world. It could also be that new fanfics with this theme are constantly being written, so popularity can shift over time.
Sure, Kakashi is present in the Boruto manga. His role might not be as prominent as in the Naruto series, but he still has significant moments and interactions.
