It's possible that their friendship would be tested by outside forces at Hogwarts. Voldemort's return and the subsequent events could put a strain on their relationship. Draco might be pressured by his family to side with the Dark Lord, while Harry is obviously on the side of good. But their pre - Hogwarts bond might make Draco question his allegiances more deeply than he otherwise would.
If they were friends before Hogwarts, it could create a lot of internal conflict at Hogwarts. Draco might be torn between his new Slytherin friends who dislike Harry and his long - standing friendship with Harry. He might try to keep their friendship a secret, which could lead to misunderstandings between them.
Their pre - Hogwarts friendship could also lead to a change in the dynamic of the Hogwarts houses. They might try to bridge the gap between Gryffindor and Slytherin. For example, they could start joint study groups or magical projects that involve students from both houses, which would be a big change from the traditional rivalry.
Well, their friendship could start with a common goal. Maybe they find out about a hidden danger in Hogwarts that the teachers are unaware of. Harry's bravery, Hermione's intelligence and Draco's knowledge of the Slytherin side of things could combine to solve the mystery. They might initially be reluctant to work together, but as they face challenges, they start to respect each other more and form a real friendship.
In some fanfictions, Draco and Harry's friendship starts with a shared experience outside of their Hogwarts house rivalries. Maybe they get lost in the Forbidden Forest together and have to rely on each other to get out. This forces them to see each other in a new light, beyond just being a Slytherin and a Gryffindor.
One possible plot could be that they meet at a wizarding event in their early childhood. Maybe their families are both attending a magical fair, and the two boys, not yet influenced by the future rivalries at Hogwarts, strike up a friendship over their shared love for magical creatures. They might spend the day together looking at baby unicorns and discussing their favorite magical beasts.
When Draco turns Harry into a vampire, it throws his friendships into chaos. His friends are used to the regular Harry, the one who battles Voldemort and plays Quidditch. Now, he has different needs and behaviors. Some friends may distance themselves out of fear. But others, like Neville, might be curious and try to help him adjust. His relationship with Ginny would also be tested as he has to deal with his new vampire nature and how it affects their relationship.
If Harry were Draco's older brother in this fanfiction, their relationship at Hogwarts would be a total mess - up of the original dynamic. Harry would be constantly torn between the Gryffindor values he adheres to and his family bond with Draco. Draco might start to question his Slytherin - only ideology because of his connection to Harry. For example, they might find themselves in situations where they have to choose between their house loyalties and their new - found brotherly bond, like during the Quidditch matches or the Triwizard Tournament.
Yes, it is possible. In some fanfictions, they overcome their differences. Maybe they find out they have more in common than they thought, like their love for Quidditch or the pressure they face from their families.
Perhaps a mutual friend like Hermione could play a role. She might set up a situation where Draco and Harry have to work together on a project. At first, they would be reluctant, but as they start to see each other's positive qualities, like Draco's determination and Harry's loyalty, they begin to respect each other and a friendship could form.
In many fanfictions, their friendship changes their social interactions. Harry was always surrounded by his Gryffindor friends, but with Draco as a friend, he starts to interact more with Slytherins. Draco, who was used to being with his Slytherin clique, now has to deal with Harry's Gryffindor friends. This new dynamic forces them both to step out of their comfort zones. It also makes them more adaptable. They learn to handle different situations and people better because of their friendship.
In some fanfictions, it initially worsens their relationship. Harry might feel violated or extremely angry that Draco would use physical force on him. This could lead to a period of intense hatred and more frequent clashes. However, as the story progresses, this event could also be the catalyst for them to eventually make amends and develop a more complex relationship.
In some fanfictions, their secret friendship begins during an unexpected event, like getting lost together in the Forbidden Forest. They realize that they are not so different from each other. Draco may see that Harry is not just the 'Chosen One' but a normal boy with fears and insecurities, and Harry may see that Draco is not all about pure - blood supremacy. This new understanding could lead to a secret pact to protect each other from the real threats at Hogwarts, like the Death Eaters or other dark forces that might target them.
