In the fan fiction, it could be that an old acquaintance of Harry's parents shows up at the Dursleys'. This person rescues Harry and takes him to a secret magical community. There, Harry encounters a girl who has a special gift. They become friends first, but as they work together to uncover a mystery related to Harry's past, their feelings turn into love. The story could focus on how their relationship helps Harry to overcome the trauma of his time with the Dursleys.
One possible plotline could be that a new character, perhaps a powerful witch or wizard, arrives at the Dursleys' place and whisks Harry away to a magical hideaway. There, Harry meets a love interest who has also been in hiding from the dark forces. They bond over their shared experiences and start to fall in love.
Perhaps in the fanfic, a time - traveling wizard goes back to save Harry from the Dursleys. This would lead to a lot of changes in the timeline. Harry might be introduced to magic much earlier and form different relationships. He could also have a different understanding of his parents' history and his own role in the wizarding world as a result of being removed from the Dursleys' environment.
In some fan fictions, Severus might save Harry from the Dursleys because he realizes that Harry is the key to defeating Voldemort in the long run. He might see that the Dursleys' treatment is making Harry weak and less likely to be able to face Voldemort. So, he intervenes, maybe by intimidating the Dursleys into treating Harry better and providing him with proper education about the wizarding world. He could also give Harry some potions to boost his health and magical abilities that have been stunted by the Dursleys' neglect.
Perhaps a mysterious half - blood who has been living on the fringes of the magical world. She has her own reasons for being near the Dursleys' neighborhood and when she sees Harry's plight, she decides to save him. As they go on the run together, they discover that they have a lot in common and fall in love. Her knowledge of the darker corners of the magical world helps Harry in ways he never expected.
Maybe Dumbledore steps in at the last moment and takes Harry away from Vernon's house. He could use his powerful magic to protect Harry and remove him from that hostile environment.
There are quite a few. One popular one is 'The Protector's Grace' where a powerful wizard steps in to rescue Harry from his miserable life with the Dursleys.
One possible plotline could be Harry adjusting to a new family that actually loves and supports him. He might discover new magical abilities or a different side of the wizarding world. Another could be his relationship with his adoptive family as they learn about his past and the challenges he faced at the Dursleys.
It could be that Daphne has a personal connection to Harry that she's not aware of until she starts investigating the strange magical disturbances around the Dursleys' place. Once she realizes it's Harry in trouble, she enlists the help of her friends or some sympathetic wizards to break Harry free. She might also face some challenges along the way, like dealing with the Dursleys' resistance or the Ministry of Magic's rules about interfering in Muggle affairs.
One possible plotline could be Harry finding a way to secretly practice magic while imprisoned. For example, he might discover a hidden corner in the attic where he can perform small spells without the Dursleys noticing.
In a 'bill cheats on harry' fan fiction, the plot could start with Bill and Harry being part of a close - knit group. Bill might be in a long - term relationship with another character. However, as he spends more time with Harry, he begins to have romantic and sexual feelings for him. He might start to hide his interactions with Harry from his partner, leading to a web of lies and deceit. This could cause a rift in the group, with Harry being conflicted about his feelings for Bill and the moral implications of being involved with someone who is 'cheating'. The story could then explore how they deal with these complex emotions and the fallout from Bill's actions.
There are fanfictions where a powerful wizard or witch, not part of the main Hogwarts faculty, discovers Harry's situation. Maybe an old hermit wizard who lives on the outskirts of the wizarding world. This wizard uses his magic to create a diversion at the Dursleys' place and then whisks Harry away to his own hidden cottage where he teaches Harry different kinds of magic not taught at Hogwarts.
