One possible reason could be that in the original 'Harry Potter' lore, Draco and Harry are from rival houses and have a history of animosity. So in fanfiction, Draco might reject Harry based on this pre - existing enmity. For example, Draco's pure - blood supremacist views might clash with Harry's more inclusive attitude.
In the 'harry rejects draco fanfiction', it could be due to the social divide between Gryffindor and Slytherin. Harry, as a Gryffindor, has been taught to distrust Slytherins. Draco's actions towards Harry's friends, like Hermione who is a Muggle - born, also contribute. Harry may reject Draco because he stands for the discrimination that Hermione has faced from Draco and his family.
Harry could be initially shocked and hurt. After all, having your potential mate reject you is a very painful experience. He might start to question himself and wonder what he did wrong. Then, he could become angry. Given his Gryffindor nature, he might confront Draco about the rejection and demand an explanation.
The rejection in the 'harry rejects draco fanfiction' could lead to a sort of cold war between them. They might avoid each other as much as possible, but in times of crisis at Hogwarts, they are forced to interact. This interaction could be filled with hostility and distrust. Draco may try to undermine Harry in more subtle ways, while Harry would be more determined to keep his distance and protect his friends from Draco's schemes.
One possible reason could be their long - standing rivalry. Draco has been taught to dislike Harry from a young age due to their family differences. His pure - blood supremacist upbringing might make him reject Harry as a mate because Harry is seen as a 'Mudblood - lover' in the eyes of Draco's family and their circle. Another reason could be fear. Draco might be afraid of what the wizarding society would think if he accepted Harry as his mate. The wizarding world has its own set of norms and expectations, and a relationship between them would be highly unconventional and likely face a lot of opposition.
It can solidify the view that they are fundamentally different. Since Draco rejects Harry, it emphasizes the divide between Gryffindor and Slytherin values that they represent. It makes their relationship seem more like a classic hero - villain dynamic, at least from Draco's perspective.
In this kind of fanfiction, it could be that the author wants to explore a different dynamic. Hermione and Ron have a long - built relationship in the original series. Maybe the author feels that Ron and Hermione have a more 'grounded' connection compared to Harry and Hermione. It could also be about showing Ron's growth and how he becomes more worthy in Hermione's eyes over Harry.
One possible reason could be differences in their social status. In some fanfiction settings, Daphne might come from a pure - blood family with high - society expectations, and Harry, being an orphan with a somewhat 'outsider' status in the wizarding world, may not meet those expectations. Another reason could be conflicting personalities. Maybe Daphne is a very reserved and traditional person, while Harry is more impulsive and adventurous, which could lead to her rejection.
Alternatively, Ginny could be very mature about it. She might respect Harry's decision, even though it hurts. She could choose to step back and give Harry the space he seems to need while secretly hoping that he will change his mind in the future.
Harry might be extremely hurt. He could initially feel a sense of shock and disbelief. After all, he may have started to develop some feelings of trust or kinship towards Severus. Then, he might turn to anger. Anger at being rejected, especially if he doesn't understand the reasons behind it. He could also feel a sense of loss, as if he has been deprived of a chance at a real family connection.
