I don't think there would be a lot of fanfiction like that. Hinata has always been loyal to Naruto. In the Naruto universe, their relationship is based on a lot of development and mutual understanding. So it's hard to imagine a scenario where Hinata would cheat on Naruto with Boruto in a legitimate fanfiction.
Well, Naruto would be in a really tough spot. He loves his family and the village, and this situation would be a huge blow to his traditional values. He might struggle to understand how this happened between his son and Hinata. Hinata's family, on the other hand, would be protective of her. Her father would want to ensure that Boruto is taking responsibility. Boruto's friends would also be surprised. Some might be supportive, like Shikadai, who would try to see the good in the situation, while others might distance themselves at first, not sure how to handle this new and rather strange development.
There are many great 'Boruto x Hinata' fanfics out there. One popular one might be those that explore their unique relationship in the context of Boruto's growth. For example, some fanfics focus on how Hinata's wisdom and kindness influence Boruto as he faces various challenges in the ninja world. These can often be found on well - known fanfic platforms by sorting through the highest - rated ones.
One idea could be a story where Boruto and Himawari discover an old diary of Naruto's from his early days as a ninja. Hinata helps them understand the context and the values their father held. They then use those lessons to face a new threat in the village.
One common theme is family. Since Hinata is Boruto's mother, many fanfics explore their family relationship, like how Hinata passes on the Uzumaki - Hyuga values to Boruto.
Yes, there are. Some fanfics imagine Boruto and Hinata going on missions together. These could be rescue missions or quests to uncover ancient ninja secrets. In these fanfics, Hinata's skills as a ninja are put to use alongside Boruto's growing abilities, creating an interesting dynamic.
One possible plot could be that Boruto and Hinata have a deep emotional bond that develops over time. They face many challenges in the Hidden Leaf Village together, which brings them closer. As a result of their love and closeness, Hinata becomes pregnant, and then they have to deal with the reactions of their family and friends, like Naruto's reaction as Boruto's father and also how the village will perceive this new development.
One good theme could be their training sessions. Maybe Hinata is teaching Boruto some of her unique ninja techniques, like her gentle fist style. This can show their bond as teacher - student within the family.
Often, they are shown as more mature and experienced. Naruto is still the strong Hokage but also a loving father. Hinata has become more confident in her role as Naruto's wife and as a mother. For example, she might be more assertive in decision - making for the family.
