One possible reason could be that Harry has post - war trauma. He might have seen so much death and destruction during the war that he doesn't want to bring his darkness and pain to the Weasleys. He may think that staying away is a way to protect them from his own emotional turmoil.
At first, the Weasleys might try to reach out to Harry. But as he continues to avoid them, they could start to feel rejected. This might lead to some resentment building up, especially among the younger Weasleys who don't understand why Harry is acting this way. For example, Ron might be really frustrated as he considered Harry one of his best friends.
Well, at first, Harry might feel a bit out of place, but the Weasleys' warm welcome would soon make him feel at home. He would start to participate in their family discussions, offer his own opinions, and be a part of their decision - making processes. The Weasleys would teach Harry things that he missed out on growing up without a proper family, like how to handle family disputes in a healthy way. Harry, on the other hand, would bring his own unique perspective to the family. His fame and the things he had been through would make the Weasleys see the world in a different way. This exchange of ideas and experiences would continuously deepen their relationship over time.
I'm not sure if it's a popular fanfiction. It's such a dark and against - the - grain concept for the 'Harry Potter' fandom that it might not have a large following. Most fans are used to the positive relationships between Harry and the Weasleys in the original series.
I haven't actually read this specific fanfiction, but it's a very dark and disturbing concept. In the normal 'Harry Potter' universe, Harry and the Weasleys are friends. So this fanfiction probably involves some sort of dark plot twist or alternate reality where Harry turns against them for reasons that could range from being influenced by dark magic to some misinterpreted prophecy or a huge misunderstanding.
In this fanfiction, the betrayal might also stem from jealousy. Harry is often in the spotlight, and the Weasleys, who have always been a big family but not always in the center of attention, could let envy get the better of them. This could lead to actions that Harry perceives as betrayal, like spreading rumors or withholding support when he needs it most.
No, it's not common. Usually, fanfiction focuses on positive relationships between characters, especially Harry and the Weasleys who are often portrayed as a close - knit family. So this would be a rather unusual and dark theme.
At first, the relationship would be tense. The Weasleys might be distrustful of Tom and Harry. But as they explain their reasons for whatever they were doing, the Weasleys could start to understand. Maybe they would offer to help Tom and Harry instead of punishing them. This could lead to a new bond between them, with the Weasleys becoming sort of mentors to Tom and Harry.
Harry could become an Auror, as he's always been good at fighting dark forces. Ginny, on the other hand, might continue her career in Quidditch. They would support each other's choices. Harry would cheer for Ginny at her matches, and Ginny would be proud of Harry for his work in keeping the wizarding world safe.
