One interesting plotline could be Naruto and Hinata going on a secret mission together in Boruto's time. They get to show off their teamwork skills that have only gotten better over the years.
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.
Well, in some fanfics, there's a plotline where Hinata loses her memory and Naruto has to make her fall in love with him all over again. It's a classic but still very engaging. There are also stories where they are arranged to be married for political reasons at first, but then they actually fall in love for real during the process. And a really unique one is when Hinata becomes a super powerful ninja overnight and Naruto has to deal with his feelings of being a bit overshadowed while also being proud of her.
A really interesting plotline might be where Hinata's aggression is a result of some new power she has obtained. This power makes her more confident and bold. She then uses this new - found aggression to help Naruto in his quest to bring peace to the ninja world. For example, she might be the first to volunteer for dangerous undercover missions, which Naruto is initially hesitant about, but she convinces him with her determination.
A possible plotline is Naruto, in Hinata's body, trying to confess his love to himself (his normal body). It would be a really strange and funny situation. He could struggle with Hinata's shyness while still having his own strong emotions. Also, in this state, he might explore Hinata's memories and understand her better. This could lead to a deeper connection between them when he returns to his own body. Maybe he discovers how much Hinata has secretly supported him all these years and feels more grateful and closer to her.
One plotline could be Naruto realizing how much Hinata means to him when he's on a long and difficult mission. He might be constantly distracted, thinking about their shared moments, like when she confessed her love during the Pain attack. Another could be Naruto in an alternate reality where Hinata is missing, and he has to search through different dimensions to find her, facing many challenges along the way.
One interesting plotline could be Hinata becoming a powerful ninja in her own right and protecting Naruto instead of the other way around. For example, she could master a new and unique jutsu that saves Naruto from a powerful enemy.
One interesting plotline could be exploring Naruto's early days of training with Jiraiya in more detail. Maybe showing his struggles and how he overcame them during that time.
Maybe they are part of an ANBU team tasked with protecting a very important person. Along the way, Hinata discovers a new power within herself, and Naruto is there to support and encourage her. This could lead to some tender moments between them and also show how they work together in a high - stakes ANBU operation. Their relationship could develop further as they face numerous challenges and threats together.
In a fanfiction, Naruto and Hinata as friends could go on a journey to find a rare flower that has the power to heal serious injuries. They encounter various obstacles like dangerous terrains and wild animals. Hinata might use her tracking skills with the Byakugan to find the right path, and Naruto would protect them from any immediate threats. As they travel, they talk about their dreams and fears, deepening their bond of friendship.
A plotline could be that young Hinata gets lost in a mysterious forest near the Hidden Leaf Village. Naruto goes to find her, and during their time in the forest, they discover an ancient ninja artifact. They have to figure out how to use it or keep it safe from evil ninja who also want it. This adventure would test their skills and bring them closer together.
