Another theme could be self - discovery. As they interact with each other, both izumi and ryouma might learn more about themselves, their strengths, and their weaknesses. For example, in some fanfics, they might discover new talents or overcome personal fears because of their relationship.
The ending of the Shikimori manga is quite satisfying. The main characters reach a conclusion that feels right for their journey, and loose ends are neatly tied up.
Sure. One great izumi x ryouma fanfic is 'The Bond of Izumi and Ryouma' which focuses on their adventures together. It beautifully portrays their relationship development through various challenges they face.
Sure, there are probably some great Olivier Mira Armstrong x Izumi Curtis fanfictions. A lot of fanfiction writers are creative and come up with unique scenarios for different character pairings. To find them, you could also join relevant fan communities on social media platforms. Members there might be able to recommend some really good fanfictions that feature this particular pairing. They might even share their own works if they have written any for this pairing.
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.
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.
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.
