It could end with Harry accepting the rejection gracefully and moving on. He might focus more on his friendships or other aspects of his life like his magic studies or adventures.
One possible reason could be that there are cultural differences between Harry and the elf. Elves might have different values and traditions when it comes to relationships. For example, their society might have strict rules about mating or partnering with non - elves.
He might be initially heartbroken. Harry has always been a bit of an emotional person, so he could go into a state of depression for a while. He might isolate himself from his friends and focus only on his studies or fighting against the dark forces, using it as a way to distract himself from the pain of the rejection.
One possible reason could be that Hermione is too focused on her studies and career goals in the wizarding world. She might see a relationship with Harry as a distraction. Another reason could be that she has different values when it comes to love. Maybe she wants someone more like her, who is more into books and intellectual pursuits all the time, while Harry is more action - oriented.
One reason could be that his mate has different life goals. Maybe she is more focused on her own magical career and doesn't see a relationship with Harry fitting into that at the moment. Another possibility is that there are misunderstandings between them. For example, Harry might have been too involved in some dangerous adventures and his mate thought he didn't value their relationship enough. Also, it could be due to external pressures, like her family or friends not approving of Harry for some reason.
Maybe Harry is turned into an elf by a misfired spell. Then he has to deal with his new small size and pointy ears while still trying to attend Hogwarts classes. He might face challenges like fitting into his regular robes or being taken less seriously by some students.
One common theme is self - discovery. When Harry gets rejected, he often has to look within himself to find his true strength. For example, in many fics where he's rejected by friends or allies, he realizes he can be independent and powerful on his own. Another theme is resilience. Harry has to bounce back from the rejection, like in fics where he's rejected from a magical opportunity but then works hard to create his own path.
In the fanfic, Harry could have a range of reactions. At first, he might be in denial, thinking that Hermione is just joking or that she will change her mind. Then, when he realizes it's for real, he could get angry, feeling like he's been unfairly judged or rejected. However, over time, he may come to accept it and focus on other aspects of his life, like his fight against the dark forces or his relationships with other friends.
It could be Voldemort. He might see turning Harry into an elf as a way to weaken him. Since elves are generally seen as lower in the wizarding hierarchy, Harry in this form would be less of a threat to Voldemort in the eyes of many wizards.
One popular 'harry gets rejected fanfic' is 'Rejected by the Golden Trio'. In this fic, Harry faces rejection from his closest friends which leads to a series of self - discovery and adventure as he tries to find his place without their support. Another one could be 'The Rejection at Hogwarts' where he is rejected by the Hogwarts community in a rather unfair situation and has to fight to regain his reputation.
