Well, there might be characters from their clan. Since Itachi is from the Uchiha clan, other Uchiha members could play significant roles. They could be elders or other young Uchiha who are involved in the clan's affairs and in turn, affect Itachi and Izumi's story.
Love and loyalty are common themes. Their love for each other often has to face the harsh reality of the ninja world, which tests their loyalty. For example, in many fanfictions, Itachi's loyalty to the village conflicts with his love for Izumi.
Their relationship would likely become more trusting. In marriage, they would have to rely on each other more. For example, Itachi might open up more about his missions and the secrets he has been keeping.
Another one is 'Itachi and Izumi: Unspoken Bonds'. This fanfiction focuses on the unspoken connection between them. It beautifully portrays how they communicate without words at times. The author does a great job of building the tension and the emotional depth between the two characters.
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.
One common theme is unrequited love. Since Itachi has so many secrets and a complex life path, often in fanfics Izumi might be in love with him while he's preoccupied with other things. Another theme could be the exploration of their shared Uchiha heritage. Writers may delve into how their clan upbringing affects their relationship.
Itachi and Izumi's relationship was a complex one. Izumi deeply loved Itachi. However, Itachi was burdened with many secrets and a difficult path in life. Their love was more of a bittersweet one as Itachi's circumstances didn't allow him to fully embrace their relationship. In the end, their love story was cut short due to the tragic events in Itachi's life.
One of the main themes could be friendship. Itachi and Izumi might have a complex relationship that explores the depths of loyalty and connection between them.
Perhaps the story could start with Itachi realizing his true feelings for Izumi after a near - death experience. He then decides to court her in a very traditional way within the Uchiha clan. Their marriage would be a symbol of hope for the future of the clan, and they face challenges together like rebuilding the Uchiha's reputation and dealing with outside threats.
