In a 'Harry forces Hermione to marry him' fanfiction, there could be a number of reasons. It could be that he has lost his mind due to some traumatic event, like seeing too many friends die. This could make him cling to Hermione in an extreme way and think that marriage is the solution to keep her close. Also, there might be some sort of political conspiracy in the wizarding world. Maybe there's a group that wants to control the power that Harry and Hermione together could potentially have, and they manipulate Harry into believing he has to marry her for the safety of the wizarding community.
Well, perhaps in the fanfiction, Harry is influenced by a powerful magical artifact. This artifact might be corrupting his thoughts and making him believe that marrying Hermione is crucial for some grand purpose. It could also be that he has some sort of false memory implanted, which makes him think that he has always been in love with Hermione and that marriage is the natural next step. Another possibility is that there's a new, unknown threat to the wizarding world, and Harry believes that their union through marriage will create a powerful bond that can defeat this threat, even if Hermione doesn't initially agree.
There could be. Fanfiction often takes canon and twists it in unexpected ways. But this particular scenario is quite controversial as it changes the essence of the characters' relationships. A well - written one would have to do a lot of groundwork to make it believable. It might involve some sort of dark magic influence on Harry or a very strange set of events that make him think marrying Hermione is the only solution to a big problem. But generally, it's not a common or easy - to - accept plot in the 'Harry Potter' fanfiction world.
One possible reason could be his over - protectiveness. Edward might think that marriage would legally bind Bella to him and he could better protect her from the various dangers in their world, such as other vampires. He may believe that as his wife, he could keep a closer eye on her.
In some fanfictions, there might be a new magical element or prophecy that makes Harry question Hermione's motives. If the prophecy says something about Hermione being involved in a dark plot, even if it's false, Harry may start to have doubts about her.
One possible reason could be that in the fanfiction, Hermione has different career aspirations. She might be so focused on her magical research or her work in the Ministry that she feels marriage would hold her back. For example, she could be on the verge of a major discovery in the field of spell - modification and doesn't want any distractions.
Maybe Draco is jealous of Hermione's intelligence and abilities. In the fanfiction world, he could think that by making her his wife, he can somehow take credit for her achievements or keep her from outshining him. It could also be a power play. Draco might believe that having Hermione under his control through marriage would give him more influence in the wizarding world, especially if she has connections that he wants to use for his own gain.
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.
It's possible that Harry hates it because he has a certain image of Ron and Hermione in his mind. Fanfiction can sometimes create versions of them that are completely different from what he knows. For example, some fanfiction might focus on a love triangle that he doesn't think exists in their real relationship. This divergence from his perception could lead to his dislike.
Power could be a reason. If there's a chance for Ron and Hermione to gain a great deal of power by turning against Harry, some fanfictions might explore this. For instance, a new dark power might offer them something they've always desired, like the ability to reform the wizarding world in their own image. They might think Harry would oppose this, so they betray him to get what they want.
One possible reason could be jealousy. Maybe Hermione gets jealous of Harry's popularity or his special connection with other characters. Another reason might be differences in their approaches to solving problems. Harry could be more impulsive while Hermione is more methodical, leading to clashes. For example, in a situation where they need to rescue someone, Harry might want to rush in without a proper plan, but Hermione would insist on having a well - thought - out strategy first.
One reason could be to find peace. After all the chaos and war in England, they might just want to get away from it all and start fresh somewhere else.
