Well, in some fanfictions, a great plotline is that the arranged marriage is a political move. This forces Harry and Ginny to work together to figure out how to deal with the political implications. They may have to attend various wizarding events as a couple, which initially they dread but then start to enjoy. Also, there could be a plotline where Ginny's family secrets are revealed during the arranged marriage process, and Harry has to support her through it, which strengthens their bond.
One interesting plotline could be the initial resistance from both Zuko and Katara. They might be forced into the arranged marriage due to political reasons. For example, to unite two war - torn regions. As they start living together, they slowly discover each other's hidden qualities. Zuko might show his vulnerable side, and Katara her more understanding and forgiving nature.
One common theme is the struggle against fate. Harry and Ginny often feel like they are being pushed into something they didn't choose, and they have to come to terms with it. Another theme is the discovery of true love. Despite the arranged nature of their marriage, they find that they can truly love each other.
One interesting plotline could be their initial resistance to the arranged marriage. Hermione, being a strong - willed Gryffindor, would likely be appalled at the idea of being married to a former Slytherin bully like Draco. Draco, on the other hand, might be resentful of being forced into a union with a Muggle - born. As they are forced to spend time together, they could gradually discover each other's hidden depths. For example, Hermione might find that Draco has a softer side beneath his cold exterior, perhaps due to his difficult family situation. And Draco could come to respect Hermione's intelligence and courage. Another plotline could involve them facing external threats together because of their union, which forces them to rely on each other and strengthens their bond.
A possible plotline is that Hermione uses her intelligence to help Sirius clear his name in the wizarding world while dealing with their arranged marriage. This could involve her researching old laws and magical artifacts. Or, Sirius could teach Hermione some of the more unorthodox magic he knows, which helps her in her studies and also strengthens their bond. Also, there could be a sub - plot where they have to pretend to be a happily married couple for a mission, and during this pretense, they actually start to fall for each other.
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 possible plotline could be Ginny being influenced by a dark magical object that makes her turn against Harry. This could lead to a series of conflicts as Harry tries to figure out what's wrong with her and how to save her. Another plotline might involve Harry and Ginny being caught in a dark prophecy that forces them to make difficult choices that seem against their nature. For example, they might have to choose between saving each other or the wizarding world.
One interesting plotline could be the paparazzi misinterpreting a friendly moment between Harry and Ginny as something more romantic, which then causes chaos in their wizarding world. For example, they might take a picture of Harry helping Ginny up after she falls during Quidditch practice and spin it into a love affair story.
One interesting plotline could be how Harry and Ginny handle their kids' magical education. For example, they might have different ideas on whether to send them to Hogwarts early or let them study at home for a while first. Another could be the family's adventures during holidays, like exploring new magical places together.
One interesting plotline could be their post - war life. How they deal with the trauma of the war and build a normal life together. For example, they might struggle with nightmares but find comfort in each other.
One interesting plotline could be Harry and Ginny having a secret date in Hogsmeade. They might discover a hidden alley with a magical shop that holds a key to solving a mystery at Hogwarts. Another could be that they encounter a strange creature near Hogsmeade and have to work together to keep it from causing chaos in the village. And also, perhaps they meet an old wizard in Hogsmeade who tells them a prophecy about their future together.
