A possible plot could involve them trying to find a loophole in the Marriage Law. They team up secretly, putting aside their differences for a while. Along the way, they face many challenges like dealing with their families' reactions. The Weasleys are horrified at the thought of Ginny being married to a Malfoy, and the Malfoys have their own expectations. But as they search for a way out, they accidentally fall in love. They then have to decide whether to continue with their plan to break the law or accept their new - found feelings.
One idea could be that the Marriage Law forces them together, but at first they are hostile towards each other. Draco is still stuck in his pure - blood supremacist ways and Ginny is a fierce defender of the Weasley values. However, as they are forced to live together, they start to see the good in each other. For example, Ginny realizes that Draco is not as bad as she thought when she sees him being kind to a house - elf. And Draco discovers Ginny's strength and courage, which he starts to admire.
One idea could be that due to the marriage law, Draco and Ginny are forced together. At first, they are hostile towards each other because of their past differences. Draco's pure - blood pride clashes with Ginny's Weasley independence. But as time goes on, they start to see the good in each other. For example, Draco realizes Ginny's bravery and Ginny sees that Draco is not as bad as she thought.
One idea could be that the marriage law forces them to live together and they initially clash due to their different backgrounds. But as they get to know each other's true selves, they start to respect and even fall in love. For example, Hermione might introduce Draco to the value of Muggle - born magic and he could show her some of the more complex pure - blood magic traditions in a new light.
Well, a great plot idea could be that they are paired by the Marriage Law and have to pretend to be a happy couple in public for some political or social reasons in the wizarding world. But in private, they are constantly bickering. As time goes on, they find that they can't help but fall for each other. They might also face challenges from Draco's old Death Eater associates who don't approve of his union with Hermione.
In some fanfictions, the marriage law plot leads to a situation where Ginny and Draco have to navigate the complex politics of the wizarding world together. Their marriage becomes a symbol of unity between different factions. They might face opposition from both the Weasley family and the Malfoy family, but they find common ground in their desire to change the old ways of thinking in the wizarding community.
Maybe the marriage law causes a stir in the wizarding world. Draco and Hermione initially resist but then realize that for the sake of the baby, they need to make it work. The baby might be born with a special gift that is a combination of the Malfoy and Granger magic. They could have to deal with Draco's family not accepting Hermione at first, but the baby becomes the bridge that brings them all together in the end.
One idea could be that their children inherit a mix of their magical abilities. For example, having Draco's skill in potions combined with Ginny's talent for charm work. Another plot could involve their children facing a new dark threat at Hogwarts and having to use their unique family heritage to fight it. Maybe they have to deal with a new type of dark magic that is a combination of old pure - blood magic and some forgotten spells.
In a Marriage Law fanfiction, their relationship would be a slow - burning one. Initially, they'd be at odds because of their family backgrounds and personal beliefs. However, as they are forced to live in the same house, they start to notice little things about each other. Draco might notice how Ginny is always there for her friends and family, and Ginny might notice Draco's intelligence and his hidden softer side. Small interactions like cooking together or taking care of the house gradually break down the barriers between them. Eventually, they fall in love, but not without many bumps in the road due to their past differences and the external pressures of the wizarding society around them.
One interesting plot twist could be that Draco and Ginny initially resist the arranged marriage but then find common ground in their shared love for a particular magical art, like potions. They start working together secretly on new potion recipes and gradually fall in love. Another twist could be that there is a mystery surrounding the arranged marriage, like it was actually set up by an enemy to cause chaos in the wizarding world. As they dig deeper, they uncover a conspiracy and have to work together to stop it. And a third plot twist might be that Ginny discovers she has a long - lost relative who is related to Draco's family, which changes their perspective on the arranged marriage completely.
One idea could be exploring their wedding planning and all the chaos that comes with it. Maybe Molly Weasley is over - involved and wants everything to be perfect, while Ginny just wants a simple ceremony. Another could be their first year of marriage, dealing with things like living together in a new home and adjusting to each other's habits.
Here's a plot idea. Ginny becomes an Auror and is assigned to keep an eye on Draco who is still under some suspicion post - war. But as she observes him, she realizes he's not the same person he was. This leads to a series of interactions where they start to develop feelings. Another could be a story where Draco discovers a dark secret about Ginny's family that she doesn't know. He has to decide whether to use it against her or help her. And a third idea is a fanfic where they are both chosen for a special magical quest that only they can complete together, and during the quest, their relationship blossoms.
