Yes, in some fanfictions, Sakura can get jealous of Hinata. For example, if Hinata has a closer relationship with Naruto than Sakura does in the story, Sakura's feelings for Naruto might make her jealous. It could be because Hinata is always so supportive and kind towards Naruto, which Sakura may feel she lacks in comparison.
Well, in fanfiction, Sakura might use her intelligence and understanding of both Naruto and Hinata to bring them together. She could notice the little things, like how Hinata blushes around Naruto and how Naruto unconsciously looks for Hinata in a crowd. Sakura could then subtly plant ideas in their heads. For instance, she might mention to Naruto how Hinata is always there for him when he's in trouble. And to Hinata, she could say how Naruto really values her presence. This way, she gradually builds a connection between them until they realize their feelings for each other.
In a Naruto and Hinata get married fanfiction, they might have a big, traditional shinobi - style wedding. All their friends from Konoha would be there, like Shikamaru, Sakura, and Kakashi. They would celebrate with lots of food and dancing.
Another theme is the development of their relationship against the backdrop of the ninja world. They often face challenges together earlier than in the original plot. For example, they might have to deal with the disapproval of some of the village elders who think they are too young or not suitable for each other. But they overcome these obstacles through their mutual love and determination.
In fanfiction, it could be for safety reasons. There might be threats or political situations in the village that make them keep their marriage a secret. For example, there could be some groups who oppose their union, and by keeping it secret, they can avoid any potential problems until they are strong enough to face them. Also, they might just want to have a simple, intimate bond without all the formalities and public attention that a normal wedding would bring.
In many such fanfictions, it could be a variety of deities. It might be an ancient and powerful god from Naruto's world's mythology that the story's author has chosen to insert. For example, it could be a god of elements like a super - powerful fire god, which could give Naruto even more control over his existing fire - based jutsu and new, more extreme abilities related to fire.
Well, a great plot could be that Naruto is feeling lost after achieving his dream of becoming Hokage. He's so caught up in his duties that he forgets about his own personal life. Hinata, on the other hand, has always been there for him. One day, she makes him a special meal and they sit down to talk. Through their conversation, Naruto realizes how much Hinata means to him and how she has always supported him. This moment of realization leads to them getting closer and eventually getting together.
Their relationship would likely bring a sense of unity to the village. Naruto is already a beloved figure, and Hinata is from a respected clan. Together, they would be a symbol of love and harmony. Their union could inspire younger generations to look beyond differences in status or abilities and focus on the importance of love and loyalty. It could also lead to stronger alliances within the village as the Uzumaki and Hyuga clans become more closely connected.
In this fanfiction, I think Sasuke could be an unexpected but interesting choice for the best man. Despite their past differences, he and Naruto have a deep bond. And for the bridesmaid, Ino would be a good option. She's fashionable and could help Hinata with all the wedding preparations. She's also a good friend to Hinata in a way.
