Another reason could be a lack of communication. Hermione is very outspoken and intellectual, while Draco is more reserved and used to a certain way of life. If they don't communicate effectively, misunderstandings can build up. For instance, Hermione might be passionate about her work for the rights of magical creatures, and Draco may not fully understand or support her in that, leading to resentment and ultimately divorce.
One possible reason could be their different backgrounds and values. Hermione is a Muggle - born witch who values knowledge, justice, and equality. Draco, on the other hand, comes from a pure - blood family with a long - standing tradition of pure - blood supremacy. These fundamental differences might lead to constant clashes in their marriage, causing them to grow apart and eventually divorce.
One possible reason could be their different backgrounds. Draco is from a pure - blood wizarding family with traditional values, while Hermione is a Muggle - born witch. Their families might not fully accept each other, leading to constant stress and ultimately divorce in the fanfiction. Another reason could be differences in their career goals. Maybe Draco wants to focus on maintaining his family's status in the wizarding world, while Hermione is more interested in promoting Muggle - wizard relations and her own academic pursuits, causing a rift between them.
Perhaps it's part of a power play. Draco comes from a pure - blood family and Hermione is a Muggle - born. In some fanfictions, this power dynamic is explored more deeply. By cutting her hair, he is trying to assert his superiority over her. It could also be an impulsive act in the heat of an argument. They might be arguing about something like blood purity or house points, and he lashes out in a very physical and mean - spirited way.
In the fanfiction, it could be related to family values. Draco comes from a family with certain beliefs about blood purity. Hermione being a Muggle - born might be seen as beneath him by his family's standards. So, Draco might abuse Hermione as a way to show his superiority based on those wrong family - instilled ideas.
One possible reason could be that Draco has had a change of heart. Maybe he realizes that Hermione is a person worthy of protection regardless of her House or her friendship with Ron. He might have seen some injustice about to befall her from Ron and his Gryffindor bravado getting out of hand.
In some fanfictions, their fight might be due to a competition at Hogwarts. Maybe they are both vying for the top spot in a particular class or for a special award. Hermione's studious and competitive nature combined with Draco's pride and desire to outdo others could easily result in a fight.
Another reason could be their different views on how to raise their children. Hermione would likely be very strict with studies and following rules, while Ron might want a more laid - back approach. Disagreements over parenting styles can put a great strain on a marriage and could be a factor in their divorce.
Some writers might do it to explore the darker sides of the characters. They want to see how Hermione, who is usually so strong and intelligent, would react in such a terrible situation. And for Draco, it could be a way to show his capacity for evil in a more extreme way than in the original books.
There could be several reasons. Draco might be facing some sort of blackmail. Someone could be forcing him to be with another person for some hidden motives. Also, his own pride could play a part. He may not want to admit that he's falling for Hermione, a Muggle - born in the eyes of some in the wizarding world. So, to prove to himself that he doesn't care about her as much as he thought, he cheats. Additionally, he could be influenced by the peer pressure within the Slytherin house, where some might not approve of his relationship with Hermione and push him towards someone else.
One possible reason could be differences in their long - term goals. Maybe Mal wants to focus more on her own kingdom and its development, while Ben is more centered around his own kingdom's affairs, leading to a rift between them.
One possible reason could be Sasuke's continued obsession with his revenge - even after they got married, his focus on past grudges might have driven a wedge between them. Another could be differences in their life goals. Sakura might have wanted a more settled family life, while Sasuke was still drawn to his wandering ways in the name of protecting the village from afar.
