In some fanfics, Naruto might feel unwanted because the author wants to explore a darker or more angsty side of his character. They may show him being excluded by the villagers even more than in the original story, perhaps to create a different kind of character development arc where he has to overcome not only external enemies but also this sense of being an outcast within his own community.
One reason might be related to his sense of responsibility. Naruto feels a huge obligation to protect the village and his friends. In fanfiction, when things go wrong or he fails in some small way, he could start to feel undeserving of all the good things in his life. He might think that if he can't fulfill his duties perfectly, he doesn't deserve the love, the power, or the status he has. Also, his own high standards for himself, which he has developed over the years of trying to prove himself, can make him feel unworthy when he falls short in any way.
In some fanfictions, Naruto might feel left out because he has a unique background. He was an outcast in the village at first. Maybe the other characters in the fanfic are forming groups or having relationships that don't include him. For example, if there are new teams being formed and he's not part of them, it could make him feel left out.
One reason could be the epic nature of both. Naruto has a grand story of a young ninja's journey to become Hokage, facing powerful enemies and saving his village. Similarly, Final Fantasy often features heroes on a large - scale quest to save the world from various threats.
One reason could be that the fanfic writer wants to deviate from the original narrative where Naruto gradually gains acceptance. They might want to put him in a situation where he has to struggle more with being unwanted to make the story more interesting. For instance, they could write a scenario where new characters are introduced and they shun Naruto for some reason.
Well, in fanfic lore, Jasper is often depicted as a protector. He has a lot of experience and combat skills. Bella could feel safe around him because she knows he can defend her from any threats. Also, his loyalty to his family and friends might make Bella trust him more, and thus feel safe.
A 'creampie' is a vulgar term often associated with sexual content. Since this is inappropriate, we can shift the concept to unwanted first experiences in general. Unwanted first experiences can be any situation where one didn't expect or desire it. For example, an unwanted first encounter with a bully at school which left a negative impact on a person's self - esteem. It's unwanted because it causes distress, discomfort or harm.
Maybe it's because he hasn't mastered all the necessary skills or jutsus. Or perhaps he's underestimating the difficulty of the exam.
It could mean that there is a fanfic related to the Greek god Ares which is considered unwanted. Maybe it has elements that are not appealing to the general audience, like a bad portrayal of the character or a plot that goes against the common perception of Ares in Greek mythology.
She might like it because it offers new perspectives on the Naruto world she knows so well. Fanfic can explore different relationships and storylines that the official series doesn't cover.
One reason is the difference in interpretation. Some fans have a very set idea of what Naruto should be, and when a fanfic goes against that, they bash it.
