In some fanfiction, this could happen due to a power play. Maybe Draco's family still has some influence and he uses it to force Harry. It could also be a result of a misunderstanding or a dark plot twist where Draco believes he has no other choice to get what he wants.
In some fanfiction, if Draco forces Hermione to marry him, it could lead to a very dark and complex storyline. Hermione, being a strong - willed character, would likely fight back in some way. Maybe she'd initially resist and try to escape. It could also involve other characters like Harry and Ron coming to her rescue. However, some fanfic authors might explore a more nuanced relationship where over time, Hermione might find unexpected understanding or even a strange connection with Draco despite the forced start.
One consequence could be a huge rift among their friends. Harry's friends would surely be against this forced union and might try to rescue him. For Draco, his friends might also be divided as some may not support such a cruel act.
I really like 'Fate's Forced Hand: Harry and Draco'. This fanfiction delves deep into the magical laws that force them to marry. It's not just about their relationship but also about how the wizarding community reacts. The author does a great job of showing Harry's confusion and Draco's pride as they are thrust into this situation. They slowly learn to co - exist and eventually find some sort of understanding and even a bit of love in the midst of all the chaos.
One way this could develop is through a dark magic plot. Maybe Draco is under some sort of spell or family obligation that he thinks can only be fulfilled by marrying Hermione. He might use threats against her friends or family in the fanfic to force her into the marriage. However, Hermione being the strong - willed character she is, would constantly be looking for a way to break free from this forced union.
She might use her intelligence. Hermione could try to outwit Draco by finding loopholes in whatever is forcing this marriage, like in the wizarding laws or contracts. For example, she could research ancient magic laws that could nullify such a forced union.
One way this plot could develop is through a political or family power play. In the wizarding world, marriages are sometimes used to strengthen alliances. Maybe the Malfoy family and some powerful wizarding families or political forces force the situation. Harry, being female in this fanfic, might initially resist but then gradually find some unexpected common ground with Draco as she gets to know him better in this forced situation.
She would probably be furious at first. Harry is known for her strong will, and being forced into a marriage, especially with Draco, would go against everything she believes in. She might try to fight it directly, using her magic skills to break free from whatever is forcing this marriage.
Some writers choose this plot because it creates a lot of drama. Harry and Draco are from rival houses at Hogwarts, so forcing them into a marriage is a huge contrast to their previous relationship. It also allows for a lot of character development as they have to overcome their differences.
This is a really interesting and dark fanfiction concept. In the Harry Potter universe, Draco and Ginny are from different houses and have different loyalties. If Draco were to kidnap Ginny to marry her, it would go against her will and the values of the wizarding world. However, it could make for a very intense and dramatic story, exploring themes of power, love, and coercion.
