One common plotline is the discovery of their brotherhood. It often involves a big reveal, like a hidden letter or a dying relative's confession. Another is them working together against a common enemy. Since they come from different backgrounds, they can bring unique skills to the table. For example, Draco's knowledge of the dark arts and Harry's courage. Also, there's the plotline of them trying to reconcile their different family values and the expectations that come with being part of the Potter and Malfoy families.
Well, one unique plotline is when Draco and Harry are forced to work together on a secret mission for the Order of Phoenix. They have to put aside their differences and learn to trust each other, which is a complete turnaround from their usual rivalry in the original books.
One popular plotline is the redemption of Draco. In these stories, Draco realizes the error of his ways and tries to make amends. As he does so, he and Harry grow closer, and eventually, they share a kiss. Another common plot is the 'enemies - to - lovers' trope. They start off hating each other but through shared experiences, like fighting a common enemy or getting to know each other's true selves, they fall in love and kiss. There's also the plotline where they are forced to work together on a secret mission, and during this time, their relationship blossoms into something more romantic.
One interesting plotline could be that after a strange magical accident, Harry discovers he is pregnant. Draco, initially shocked, gradually feels a sense of protectiveness towards Harry. They have to hide this from the wizarding world which is full of prejudice. Another could be a spell gone wrong during a duel that results in this unexpected situation, and they then must work together to figure out how to deal with the physical and emotional changes, all while still being at odds with their respective friends and families in Hogwarts.
One way they could be brothers in a fanfiction is if there was a mix - up at the orphanage or some sort of magical interference in their early lives. Maybe a powerful spell was cast that made them related, and as they grew up, they had to deal with the strange connection while still having their different personalities and allegiances at Hogwarts. Draco, with his pure - blood family values, and Harry, with his own sense of justice, would have a very complex relationship.
One common theme is redemption. Many fanfictions explore Draco's journey towards redemption and how Harry can play a part in it. For example, Draco realizing the error of his ways under the influence of Harry's more noble values.
One possible plotline could be Fem Draco Malfoy having to team up with Harry Potter on a secret mission in Hogwarts. Along the way, they start to see each other in a new light and develop an unexpected friendship that gradually turns into something more. Their different backgrounds and personalities create a lot of interesting dynamics.
The power of forgiveness also pops up a lot. Harry, being the hero he is, often has to grapple with whether to forgive Draco for all the mean things he's done in the past. And this struggle and the ultimate act of forgiveness (or not) can be a major part of the story. Fanfictions might explore how this impacts their relationship and the wizarding world around them.
The theme of breaking social barriers is also prevalent. In the wizarding world, same - sex relationships might face some challenges, and these fanfictions often show Harry and Draco fighting against such prejudices. For example, they might have to deal with the reactions of their families and friends.
One common theme is redemption. Draco is often seen as a character who needs to redeem himself, and his relationship with Harry as mates can be a part of that journey. For example, in many stories, Draco realizes the error of his ways through his bond with Harry.
Overcoming prejudice is also a big theme. Since they are from different houses with a long - standing rivalry, they have to break through the walls of prejudice that their fellow students and the wizarding world in general have towards their relationship. For example, Gryffindors might be shocked that Harry is soulmates with a Slytherin like Draco.
