A third plotline could be set in an alternate universe where the war never happened. Hermione and Draco are arranged to be married for political reasons. Hermione initially resents this but Draco is intrigued by her intelligence. As they start to build a life together, they discover that love can grow out of an arranged situation. They then work together to make changes in the wizarding world, using their combined knowledge and influence.
Another plotline could involve a magical accident that binds their fates. Hermione and Draco find themselves magically married against their will. At first, they are furious and try to find a way to break the spell. But as they get to know each other during this time, they start to develop real feelings. Hermione might teach Draco about the importance of equality and he could show her some of the more nuanced aspects of Slytherin culture.
One interesting plotline could be their struggle to overcome the prejudices of their respective Houses. Since Draco is from Slytherin and Hermione from Gryffindor, their marriage would shock many at Hogwarts. They might face opposition from their old friends and families. Another plotline could be them working together to improve the relations between Muggle - borns and pure - bloods. Draco, with his pure - blood background, and Hermione, as a strong advocate for Muggle - born rights, could make a powerful team in the wizarding world's fight against blood - based discrimination.
A plot could be that Draco and Hermione are in a situation where they are magically bound to each other for a certain task. Hermione makes a decision that Draco thinks is foolish and nearly gets them both in trouble. So, Draco punishes her by not allowing her to use her favorite magic items for a while. This makes Hermione frustrated but also makes her realize she needs to be more careful. Another idea is that in a fan - created magical world, Draco is in charge of a group that Hermione wants to be part of. She fails an initiation test set by Draco, and his punishment is to make her serve the group without having any of the privileges for a period of time. This could create a complex relationship between them as Hermione tries to earn her way back into Draco's good graces.
One possible plotline could be that they are forced to work together on a difficult project in Hogwarts, and during the process, they start to see each other in a new light and eventually share a kiss. Another could be in a post - war scenario where they have to put aside their previous differences for the greater good of the wizarding world, and feelings develop leading to that kiss. Maybe in an alternate universe where the Gryffindor - Slytherin rivalry doesn't exist in the same way, they meet under different circumstances and fall for each other, which results in the kiss.
Maybe they meet in a secret place during their school years, away from the prying eyes of their classmates. They start to exchange ideas and knowledge, which gradually turns into a deep emotional connection. This connection then leads to a secret marriage, and they have to deal with the consequences of hiding it from everyone they know.
One possible plotline could be Draco and Hermione being forced to work together on a difficult school project. Despite their initial animosity, they gradually come to respect each other's intelligence and skills. Another could be a situation where they are both in danger and have to rely on each other for survival. This forces them to set aside their differences. And a third could be a magical accident that causes them to swap personalities or abilities, leading to some humorous and also relationship - building moments.
Well, perhaps there's a plot where they are both entered into a magical tournament against their will. In the process of competing, they realize they have more in common than they thought. For example, they both have a strong desire to prove themselves. This shared feeling makes them bond and slowly become friends, or even more, in the fanfiction world.
One interesting plotline could be that Draco and Hermione are forced to work together in a cancer research project at Hogwarts. They start off hating each other as always, but as they see the effects of cancer on patients, they gradually put aside their differences. Hermione's vast knowledge of magic and Draco's family's connections to certain potions ingredients could lead to them making a significant discovery in the fight against cancer in the wizarding world.
One interesting plotline could be Hermione trying to cure a werewolf - affected Draco. Maybe she discovers a new spell or potion that can ease his lycanthropy symptoms. It could lead to a lot of tense moments as they have to trust each other despite their past differences.
Perhaps a plot where they all become animagi and have to use their animal forms to solve a mystery in the Forbidden Forest. Draco as a sleek snake, Harry as a stag, and Hermione as an otter, they must navigate the forest's dangers and uncover the truth about a strange magical disturbance.
One possible plotline could be that Draco, in his 'evil' guise, is initially set on causing trouble for Hermione at Hogwarts. But as the story progresses, he might start to have complex feelings for her, leading to an internal struggle between his dark intentions and new - found emotions.
