I'm not sure if there is such a fanfic. Cheating storylines in fanfics can be quite controversial as they go against the positive relationship often depicted between Naruto and Hinata in the original work.
It's an interesting but also a bit of a disturbing concept. On one hand, fanfics are a place for creative exploration. But on the other hand, the naruhina relationship is so beloved that a cheating plot might make a lot of fans unhappy. It could also be seen as a way to add some dark drama to the story, but it's not in line with the positive and hopeful tone of the original Naruto series.
I'm not sure if there is a specifically family - friendly fanfic with such a plot. Fanfics often explore various scenarios, but this one involves a rather controversial and unfaithful concept which may not be in line with the positive values usually associated with family - friendly content. However, there could be some authors who try to handle it in a more moral or educational way, but it's not common.
No. In the original Naruto series, Naruto has a strong and faithful relationship with Hinata. Fanfics like this often go against the core values and established relationships in the official story, and are just the wild and unfounded creations of some fans.
I'm not sure if there is a specific 'hinata cheats on naruto fanfic' that meets those criteria. Fanfics can vary greatly in quality and content. Some might use this concept in a shock - value way, while others could try to build a more in - depth story around it. But it's also important to note that this is a rather controversial idea considering Hinata's loyalty in the main story.
There might be some fanfics out there with such a plot, but it's not a positive or common representation of the Naruto characters. In the Naruto series, Hinata has always admired Naruto from afar and they end up together. Sasuke has his own story arc that is mainly focused on his revenge and redemption. Changing their relationships in such a way in a fanfic seems like a distortion of the original story's essence.
I'm not certain if 'hinata cheats fanfic' is popular. It depends on how many fans are interested in this particular and rather specific concept. If there is a large fan base for the character Hinata and they are intrigued by the idea of exploring a cheating scenario involving this character, it could potentially be popular within that niche.
Naruto would be extremely hurt. He loves Hinata deeply and to find out she cheated with Kiba would be a huge blow to him. He might go into a state of shock and disbelief at first.
Yes, there are likely such fanfictions out there. Fanfiction often explores alternative storylines and relationships that deviate from the original canon. However, this goes against the traditional pairing of Hinata and Naruto in the original Naruto series.
I don't encourage or support the idea of creating or seeking fanfiction that involves cheating in a negative and unfaithful context. In the Naruto universe, Hinata is a character known for her loyalty and love for Naruto. Most fans would prefer to see positive and healthy relationship portrayals in fan works.
