Luna Lovegood could also be a great choice. Her unique personality might intrigue Draco. She could be the one to show him a different way of looking at the world, and her kindness might break down his cold exterior during his 6th year.
Perhaps Hermione Granger. Their dynamic of being on opposite sides could create a lot of tension and interesting storylines. Draco could start to see Hermione in a new light as he realizes her intelligence and courage.
Another plot could involve Draco forming an unlikely alliance during his 6th year. For example, he teams up with a Muggle - born student to solve a mystery within the school walls. This would show his growth and changing perspectives. As he gets closer to this student, he starts to question the pure - blood ideology he was raised with.
Luna Lovegood might also be a possible love interest. Her unique personality and view of the wizarding world could attract Harry in a different way. She's not afraid to be herself and is very open - minded. In an AU, Harry could see her in a new light and they could start a relationship based on their shared experiences of being a bit different from the norm in Hogwarts.
I really liked 'Draco's Sixth Year Redemption'. In this fanfic, Draco starts to question his loyalty to the Death Eaters. His interactions with Harry become more frequent and meaningful. They find themselves in a situation where they have to rely on each other in a way they never expected. It's a story that gives a fresh perspective on their characters during that crucial sixth year.
Luna Lovegood could be an interesting pairing. She's a Ravenclaw with a very unique view of the world. Her dreamy nature could contrast with Draco's more cynical side, and perhaps she could help him see the magic in the world in a different way.
Obviously, Draco Malfoy is the main character. But other important characters could include Harry Potter. Their relationship might be explored further. Hermione Granger could also be there, perhaps helping Draco with his studies or his new - found quest for redemption. And Blaise Zabini, as Draco's friend, could play a significant role in his 8th year adventures.
Perhaps in this 7th - year fanfiction, Harry and Draco are both trying to find a way to end the war secretly. They start to communicate through a magical object that allows them to talk without being detected. As they share their thoughts and ideas, they develop a new - found respect for one another. They might even become friends in the end, and this friendship could play a crucial role in bringing peace to the wizarding world.
They might get paired up for some sort of magical exploration. Maybe they are sent to an ancient and dangerous part of the Forbidden Forest. Along the way, they argue at first but then start to open up. Draco could share his dreams of a different future for his family, away from the dark side. Harry could talk about his hopes for a post - war wizarding world. This shared journey could lead to a deeper bond between them.
A Beauxbatons student could be his love interest. Maybe a confident and intelligent witch who is at the top of her class in Beauxbatons. She could initially be put off by Draco's Slytherin reputation but then sees his softer side. Another option could be a half - blood student at Beauxbatons who is an outcast among the pure - blood - dominated school. Draco, being a Slytherin from a pure - blood family, could be drawn to her uniqueness.
It could be his father. Lucius Malfoy's actions and his ties to the Dark Lord might put Draco in a difficult position. Draco might disappear to escape the consequences of his father's actions or to avoid being used further in the Dark Lord's plans.
It could be some of the more radical pure - blood supremacists. They might see Draco as a symbol of the old pure - blood families that are starting to lose their influence. By kidnapping him, they hope to send a message to the Malfoy family and other pure - bloods that they need to be more aggressive in maintaining their status.
