One popular theme could be the idea of redemption for Draco. In many fanfictions, he is shown to overcome his family's dark past and prejudice. Another theme might be the power of friendship or love that develops between Hermione and Draco, despite their initial differences. It could also explore how they navigate the complex wizarding world together, facing challenges from their respective houses and the general wizarding society.
In a fanfiction with this theme, it could be set post - war. Draco and Hermione find themselves in a situation where they are on the run from some dark wizards who are after them for different reasons. During their escape, Hermione gets wet and cold. Draco, having a change of heart after the war, gives her his warm cloak. This act of kindness begins to break down the barriers between them, and they start to have deeper conversations, realizing they have more in common than they thought.
Perhaps there's a fanfiction where a powerful and dark wizard from outside the school is targeting Muggle - borns. Hermione, being a Muggle - born, is understandably afraid. Draco, who has always had a complex relationship with Hermione, is conflicted. He doesn't want to see her hurt because, deep down, he has feelings for her. He ends up using his Slytherin cunning to outwit the dark wizard and keep Hermione safe.
One reason could be the traditional rivalry from the original series. In the books, they are from different houses, Slytherin and Gryffindor, which have a long - standing feud. Fanfiction writers might play on this by having Draco be mean as a continuation of that in - built tension. Another aspect could be his family upbringing. The Malfoy family has certain pure - blood supremacist views, and Hermione being a Muggle - born might be a target for Draco's meanness in fanfictions.
She could stand up to him. Hermione is known for her intelligence and quick - wittedness. So she might use her sharp tongue and logical arguments to put Draco in his place. For example, she could expose his wrongdoings or the flaws in his pure - blood ideology.
One alternative theme could be a time - travel story where Hermione and Draco are sent back in time and have to work together to preserve the wizarding world's history. It's a fun way to explore their characters in a new setting.
In a different fanfiction, Hermione could be afraid of a prophecy that involves her and Draco. The prophecy seems to foretell doom and destruction. She's terrified of what might come to pass. Draco, who also hears about the prophecy, tries to comfort her. He tells her that prophecies can be misinterpreted and that they can change their fate together. He starts to work with Hermione to figure out a way to avoid the bad outcomes predicted by the prophecy.
There's 'Manacled' which is quite well - known. It has a complex plot where Hermione is in a difficult situation and Draco plays a significant role. The story is full of twists and turns that keep readers hooked. It explores their relationship in a very intense and unique way.
Draco might start to show his more caring side. For example, he could become very protective of Hermione during her pregnancy, which is a big change from his former Slytherin coldness.
Ron Weasley often makes an appearance. He might be suspicious of Draco's intentions towards Hermione and try to protect her. His loyalty to Hermione and his hot - tempered nature can add a lot of drama to the story.
