I'm not entirely sure there is a specific 'Naruto is a Uchiha death fanfiction' in a common sense. Naruto is a main character in the Naruto series and the Uchiha are a significant clan in it. If it's a fanfiction, it might be some writer's very specific and perhaps dark take on the Naruto universe where Uchiha deaths play a central role.
Their relationship could develop through mutual understanding. Naruto's open - hearted nature would help Izumi open up more. Izumi, in turn, would support Naruto in his duties as a village hero. They might start by sharing small things like their favorite foods and gradually move on to deeper conversations about their dreams and fears.
He would be super excited. Zuko would probably be right there on the floor with Izumi, coaxing her to take those first steps. He might hold out a small, shiny object from the Fire Nation as an incentive.
In the original Naruto story, Naruto is mainly focused on becoming Hokage and bringing peace to the village. However, in a 'Naruto is a Uchiha death fanfiction', Naruto's character arc might revolve around the Uchiha deaths. For instance, he could be more involved in uncovering the truth behind the Uchiha massacre or trying to prevent further Uchiha deaths.
I'm not sure about a specific one. But you can try looking on fanfiction websites like Archive of Our Own. There might be some well - written stories about Itachi and Izumi in that kind of situation.
One common theme could be the challenges they face as a couple with an upcoming baby. Maybe dealing with the secrecy in Itachi's life given his situation in the Naruto story. Another could be their relationship development during the pregnancy, like how they support each other.
