Rock Lee could be the best man. He's always been one of Naruto's biggest supporters. His energetic and positive attitude would add a lot of fun to the wedding. He would be there cheering Naruto on and making sure the whole event is full of excitement.
I think Shikamaru would make a great best man. He's Naruto's friend and he's also very intelligent. He could help Naruto with all the arrangements and keep things in order during the wedding, which Naruto might not be so good at himself.
One possible plot could be that Naruto and Fuu meet during a mission. Fuu is initially intrigued by Naruto's determination. As they spend more time together, they discover they share a similar sense of humor. Eventually, Naruto realizes his feelings for Fuu are more than just friendship and he proposes. Their wedding would be a grand affair, with all of Naruto's friends from Konoha attending.
I really liked the fanfic 'Naruto and Fuu's Adventure'. It takes them on a journey outside the Hidden Leaf Village. They face various challenges together, and it's really exciting to see how their relationship develops throughout the story.
In the fanfiction, their relationship could develop in a very passionate way. Since Naruto is a very emotional and energetic character, and Fuu has her own charm. When they decide to have a child, they would be super excited about the future. However, they would also face difficulties like any couple. There might be times when Naruto's duties as a ninja conflict with his family life, and Fuu would have to be understanding. And vice versa. Through these ups and downs, their love for each other and their child would keep their relationship strong.
Sasuke could be a rival. He's always been competitive with Naruto, and he might see Fuu as an obstacle in Naruto's path. Also, some of the more arrogant ninja from other villages, like those who look down on Naruto's boisterous nature and Fuu's different style of fighting, could be rivals.
Naruto would initially struggle with the formalities of a political marriage. But as he spends time with Fuu, he would start to adapt. His character would become more refined in terms of handling political matters. He would learn from Fuu's grace and intelligence. Fuu would also change. She might become more assertive, as she has Naruto by her side. She would be more involved in making decisions for the greater good of both villages. Their characters would grow together, with Naruto's boldness and Fuu's tact combining to create a strong leadership duo for their joined communities.
Naruto's personality would likely become more mature. The responsibility of being in an arranged marriage might make him think more about the future. He would still keep his positive and determined side, but now he has someone else to consider. Fuu's personality could soften. She might start to open up more and show her vulnerable side to Naruto. The marriage could be a catalyst for her to become more trusting and less guarded.
One great 'Naruto Fuu and Gaara' fanfiction is 'The Bond Beyond Nations'. It focuses on how Fuu and Gaara's relationship develops over time, with Fuu being a character who initially misunderstands Gaara but then comes to see his true self. It has a lot of well - written emotional moments.
In this fanfiction, Naruto might teach Fuu about the values of the Hidden Leaf. He could introduce her to his friends and show her a different way of life compared to what she's known.
I think Kiba and Akamaru would be really fun to include. Kiba's boisterous nature could create some comical moments during the wedding preparations or at the wedding itself. Akamaru could also be part of some cute interactions with Naruto and Fuu. Tsunade would also be an important character. As the Hokage, she could have some say in the marriage, or at least offer her wisdom and support to Naruto. And Rock Lee could be there, showing off his crazy training regime and giving Naruto some motivation for his new married life.
The story might progress with Fuu adapting to the Leaf Village's lifestyle.
