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 common plotline could be Draco getting punished for his past actions at Hogwarts, like his bullying behavior. Maybe he's made to do community service within the wizarding world, helping those he once looked down upon. Another could be that he's punished by his family for not following their pure - blood supremacist ideals, leading to him having to find his own path while dealing with the consequences of their disapproval.
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 possible plotline could be a story where Draco realizes his true feelings for Hermione later in life. He might initially approach her with the idea in a rather clumsy way, leading to a lot of misunderstandings and drama. For example, he could be from a family that is pressuring him to have an heir, and he sees Hermione as the perfect person to have a family with. But Hermione is focused on her career and has to decide if she wants to put that on hold for a relationship and potential pregnancy.
One plotline could be that they are magically bound to the apartment and can't leave until they resolve some deep - seated issues between them. Maybe there's a spell that requires them to get along and understand each other's perspectives.
One possible plotline could be that Draco kidnaps Hermione due to some dark family obligation related to her birth. Maybe there's a prophecy that involves her and his family wants to control the situation. Another could be that he's misinformed about her birth and thinks she's a threat to the wizarding world as he knew it. So, he takes her to figure out the truth.
One possible plotline could be that through some sort of time - travel magic, Hermione goes back in time and meets Salazar. They fall in love in a very unexpected way, and then she becomes pregnant. The story could then focus on how she tries to adapt to the ancient wizarding world while being pregnant and dealing with the differences in magic and society from her own time. Another plotline might be that Salazar somehow returns to the modern day in a spirit or reincarnated form, and he and Hermione form a connection that leads to her pregnancy, and the story could explore how the wizarding community reacts to such a strange union.
One possible plotline could be that Draco realizes the error of his ways immediately after cheating. He spends a great deal of time groveling and trying to prove his love for Hermione anew. He might do grand gestures like giving her rare magical items or standing up to his old pure - blood supremacist friends when they say mean things about Hermione. Hermione, initially hurt and angry, gradually sees his sincerity and decides to forgive him as she still has deep feelings for him.
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.
Well, one plotline could be that Hermione is heartbroken by Ron's cheating. Draco, who has secretly admired her from afar, steps in to comfort her. This leads to them exploring a relationship that was previously unthinkable due to their houses' rivalry.
One possible plotline could be that Voldemort gives Hermione to Draco as a way to test Draco's loyalty. Draco, who has his own complex feelings towards Hermione, might initially be conflicted. He could be ordered to torture her for information, but instead, he tries to protect her in secret. This could lead to a series of events where they form an unlikely alliance against Voldemort.
