For Itachi, he could become more open and less brooding. Hinata's love and support might make him feel like he can finally let go of some of his past burdens. For Hinata, she could gain more confidence in herself. Being with Itachi, who is highly skilled, gives her the motivation to train harder and become a stronger ninja. Also, she might become more assertive in dealing with clan matters, especially when it comes to any opposition to their relationship.
One possible plot could be that Itachi, after leaving the Akatsuki and resolving his issues, meets Hinata. Hinata, with her kind heart, helps Itachi adjust to a normal life. They gradually fall in love and decide to get married. Their wedding could be a small, private affair with only their closest friends present, like Naruto and Shikamaru for Itachi, and Sakura and Ino for Hinata.
One interesting plot idea could be a story that focuses on their wedding preparations. It could show how Naruto, who is not used to all the formalities, struggles with choosing the right wedding kimono or learning the proper wedding etiquette. Hinata, on the other hand, is more in tune with the traditional aspects but is nervous about becoming the wife of the Hokage. Another idea could be a time - travel fanfic where they go back in time to their first meetings and relive those moments with the knowledge of their future together. It would be a chance for them to see how far they've come and how their relationship has developed over the years.
One idea could be that they are brought together through some kind of post - war alliance building. With the ninja world in a state of rebuilding, their villages see the marriage as a way to strengthen ties. Hinata, with her gentle nature, slowly breaks through Sasuke's cold exterior as they navigate the challenges of married life together, like dealing with family expectations from both the Hyuga and Uchiha clans.
One plot idea could be a time - travel fanfic. Naruto, Sakura and Hinata are sent back in time to their childhood days. They remember their future lives where they got married. This knowledge makes them act differently. Naruto tries to avoid some of the mistakes he made in the past. Sakura focuses more on her medical ninjutsu from a young age. Hinata works on her confidence even earlier. Eventually, they still end up getting married in a more perfect way than in the original future they knew.
For Naruto, as a female, she might become more confident in her femininity while still maintaining her strong ninja spirit. She would grow in her ability to understand Sasuke on a deeper level. Sasuke, on the other hand, would become more empathetic. His cold exterior would soften as he is influenced by Naruto's warmth. He would also learn to be more domestic, sharing responsibilities in their relationship.
For Jaune, he might become more confident and assertive as he takes on the role of a husband. He could also develop new combat skills as he protects Neo. Neo, on the other hand, might start to open up more and show her softer side. Maybe she becomes more trusting of others.
One idea could be a story that focuses on their wedding preparations. It could show how Naruto is clueless about most of the traditional wedding stuff in the Hyuga clan, and Hinata has to patiently explain it to him. Another plot could be set after their marriage, where they face challenges in balancing their ninja duties and family life. For example, a mission comes up that might take Naruto away for a long time right after their honeymoon, and they have to figure out how to deal with it as a newlywed couple.
Well, in a Naruto and Hinata married fanfiction, their married life would likely involve Naruto constantly going on missions but always coming back to Hinata's warm embrace. Hinata would support Naruto in his Hokage duties, and they'd probably have family dinners with their friends from the village. Maybe they'd have a daughter who Hinata would train in the gentle fist style while Naruto taught her some of his own ninja tricks.
The fanfiction 'Marriage of the Uzumaki and Hyuga' is quite popular. It explores the cultural differences between the Uzumaki and Hyuga clans and how Naruto and Hinata bridge those gaps in their marriage. It has some really nice descriptions of their wedding ceremony, incorporating both clan traditions. 'A Hokage's Marriage' is also worth reading. It focuses on Naruto's role as the Hokage and how Hinata supports him in his duties while also building their own family. There are some great emotional moments in this fanfic when Naruto realizes how much Hinata means to him in his new role.
One possible plot could be that after years of knowing each other through the ninja alliances and various missions, Gaara and Hinata start to develop feelings for each other. Hinata is initially shy about her new - found feelings as she has always been a bit reserved. Gaara, on the other hand, is also hesitant as he has his own responsibilities in Suna. But as they keep meeting and working together, they realize their love is real. Eventually, they decide to get married, uniting the Hidden Sand and the Hidden Leaf in a new way. Their wedding could be a grand affair with ninjas from all over coming to celebrate, and it could also signify a new era of peace and cooperation between the two villages.
