Without more context, it's hard to say exactly who Harry is. But given the phrasing, it could be a reference to Harry Potter, as he is a very well - known character who is often the subject of fanfiction.
Maybe in some fanfictions, Ron is portrayed in a way that doesn't match Hermione's idea of him. For example, he might be made overly clumsy or insensitive, which could annoy Hermione.
One possible novel could be 'The Heart's Rebellion'. Here, the heroine is fed up with the societal norms and expectations placed on her in the pursuit of love.
If we consider 'harry is fed up fanfiction', it could be that Harry is a character who has been the subject of numerous fan - made stories. He might be fed up because these fanfictions often take creative liberties that he's not comfortable with. Fanfiction can range from being very positive and in - line with the original spirit to being quite out - there and off - putting. Harry could be frustrated with the lack of control over how he's depicted in these fan - created works. He might feel that his character is being misrepresented or that the fanfiction is encroaching on his own sense of identity within the fictional world.
Maybe he's fed up because the fanfiction often misrepresents the Order's values or actions. In some fanfictions, the Order might be depicted in a way that doesn't align with how he knows them, which could be frustrating.
Another reason could be that the fanfiction is full of clichés when it comes to their relationship. It always follows the same tired plotlines, and Hermione, being the intelligent and forward - thinking witch she is, is tired of seeing such unoriginal takes on their relationship.
Perhaps Naruto is fed up with Konoha's fanfiction because he wants a new adventure outside of the village. He has spent most of his life in Konoha and might be craving for a change. He could be bored with the same old politics and power struggles within the village. Also, he may have realized that the ideals of Konoha are not as perfect as they seem, and this disillusionment makes him tired of it.
Well, there are several reasons. Dumbledore is this all - knowing figure in the original series, but in fanfiction, his actions can be seen as manipulative. He might be making decisions for Harry without really considering Harry's feelings or wishes. Also, Dumbledore's grand schemes might not always be in Harry's best interest. Harry might realize this and get fed up. For instance, if Dumbledore is using Harry as a pawn in a bigger battle against Voldemort, Harry would likely be angry when he figures it out. And Dumbledore's failure to prevent certain tragedies, like the death of Sirius, could also be a reason for Harry's disillusionment.
One reason could be the over - saturation of certain types of fanfiction. If there are a ton of fanfictions that follow the same tired tropes, like Harry always being the hero in the exact same way or his relationships being portrayed in a very clichéd manner, it could lead to this feeling of being fed up.
