There is no well - known and established love story between Arti Singh and Sidharth Shukla. While they may have interacted in the context of their work in the entertainment field, it doesn't necessarily translate into a romantic relationship. People might misinterpret their on - screen or off - screen chemistry as something more, but it could just be friendly camaraderie.
There are likely some rumors out there. Since they are both part of the same industry and might have been seen together or interacted in some way, the rumor mill can start churning. However, it doesn't mean there is any truth to it. They could just be professional colleagues who are friendly with each other.

Perhaps in the fanfiction, some sort of dark magic or curse has been placed on Naruto. This could be messing with his mind and causing him to act in an insane manner. It could be a way for the author to introduce a new and dark plot element to the story. Another cause might be that he has been betrayed by those he trusts the most, which shatters his mental state.
