There could be a fanfic with this title, but the use of 'lemon' makes it a bit suspect. In the world of fanfiction, there are so many different takes on Naruto and Hinata's relationship. But if it's a 'lemon' fanfic, it's likely to contain adult - themed content. So, if you're looking for proper, non - inappropriate fanfics about them, you should look for ones that are rated for general audiences.
Sakura could be a common character. Since she has a history with Naruto, she might be part of the harem in some fanfictions. Also, Tenten could be included as she is another female ninja in the Naruto universe. And Ino, with her strong personality, could also be written into the harem scenario.
For Naruto, you can show his more romantic and sensitive side. He could be more attentive to Hinata's feelings and needs. For example, he might bring her flowers just because. Hinata can be developed by showing her becoming more confident in the relationship. She could start to initiate dates or activities.
One reason could be envy. Maybe Naruto sees Hinata as having something he doesn't, like a more stable family situation, and he lashes out in jealousy. Another reason might be that he's just being a typical, rambunctious kid who doesn't realize the impact of his words or actions on Hinata.
One great 'Naruto loves Hinata' fanfic is 'A New Beginning'. In this fanfic, it shows Naruto realizing his true feelings for Hinata after the war. It beautifully portrays their relationship development, from Naruto's initial confusion to his deep and abiding love for Hinata. Another one is 'The Road to Forever'. Here, the author takes a different approach, exploring how Hinata's long - held love for Naruto changes and grows as they face new challenges together in the post - war shinobi world.
Hinata supports Naruto by being his emotional anchor. When facing the Juubi, Naruto can get caught up in the chaos and danger, but Hinata is there to remind him of his humanity and the things he's fighting for. For example, with a simple look or a kind word, she can calm him down in the heat of battle.
A fanfic about Naruto and Hinata's wedding could start with the preparations. Hinata would be shyly picking out her wedding dress with the help of Ino and Sakura. Naruto would be out with Kakashi, getting some last - minute advice on marriage. The day of the wedding arrives, and the whole Hidden Leaf Village is decorated. As they exchange vows, Naruto promises to always protect Hinata and their future family, and Hinata vows to support Naruto in all his dreams, ninja or otherwise.
In some Naruto fanfictions, Hinata could potentially be portrayed as a 'weapon' in a very metaphorical sense. For example, her Byakugan abilities might be exploited in unique ways that make her seem like a strategic weapon for a side or a cause. But in the canon Naruto story, she is a character with her own agency and not really a weapon.
One great source for Naruto and Hinata fanfiction could be FanFiction.net. You can search for stories specifically focused on their relationship there. There are often new and interesting takes on their story, from how they first fell in love to their married life in the future.
