Well, it could be that they have a sleepover at Hinata's place. They might cook a simple meal together like ramen. And then, while sitting around, Naruto could accidentally fall asleep first. Hinata might then take a moment to watch him sleep peacefully, blushing a bit as she realizes how much she cares for him. Later, she might cover him with a blanket and quietly go to sleep herself.
Maybe there's a moment when they both fall asleep on the couch, leaning on each other. In the morning, when they wake up, they're a bit embarrassed at first but then they realize how comfortable they were together. And they start their day with a big smile, ready to face whatever comes next.
Well, they could just talk about their dreams. Maybe Naruto would finally open up to Hinata about his insecurities. They might share some childhood stories while munching on snacks that Hinata prepared.
A really cute moment could be when Hinata tries to make Naruto some tea and she's a bit nervous so she almost spills it, but Naruto just laughs it off and says it's okay. Another cute moment might be when they are getting ready for bed and Hinata offers Naruto one of her extra pillows, and Naruto thanks her with a big grin.
Naruto, Sasuke, and Sakura are the most obvious choices. They are the main characters and their interactions are always interesting. Naruto would bring his energetic and fun - loving nature, Sasuke his brooding intensity, and Sakura her intelligence and strong - willed personality.
Perhaps they have a competition to see who can do the best ninja - related magic trick. Naruto might try to use his shadow clone jutsu in a creative way, like making the clones form a human pyramid. And Sakura could use her chakra control to make small flowers bloom in their hands, which would be really cool and add a touch of beauty to the sleepover.
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.
Perhaps in the fanfiction, Hinata wears a micro bikini for a special festival in the Hidden Leaf Village. Naruto is really excited to see her in it. They participate in the festival games together and Hinata's new look makes Naruto see her in a different light, more as a strong and confident woman.
One possible plotline could be a story where Naruto has to choose between two versions of Hinata, the original Hinata and a version from an alternate RTN (Road to Ninja) universe. Maybe in this fanfiction, the different Hinatas have unique abilities or personalities that make Naruto's choice more difficult.
