One possible storyline could be that Draco and Hermione initially keep their relationship a secret. They struggle with how the wizarding world will react to their union. As they are expecting twins, they face even more challenges. Hermione might be worried about how her friends, like Harry and Ron, will take it. Draco could be concerned about his family's reaction. But in the face of all these, they start to build a home together, preparing for the arrival of their twins. They might also have to deal with threats from those who oppose their relationship.
One way could be through a time - travel plot. Maybe some magical accident sends Hermione back in time and she ends up in a relationship with Draco. Their different backgrounds would create a lot of tension. For example, Hermione's Muggle - born status and Draco's pure - blood family values. But as they get to know each other better, they fall in love and then the unexpected pregnancy occurs. This would shock the Hogwarts community as they are from rival houses and different social circles.
One possible storyline could be that Katniss and Peeta are living in a post - Hunger Games world. They find out about the pregnancy, which is a huge shock as they are still dealing with the trauma of the Games. The twins could symbolize a new hope for their district. Maybe there are difficulties during the pregnancy, and they have to rely on the support of their friends like Haymitch to get through it.
Harry and Ron would probably be shocked at first. Ron, especially, might have a hard time accepting it because of his past relationship with Hermione. But eventually, they would come around because they care about Hermione. Ginny would likely be more open - minded and try to be supportive. Other friends from Hogwarts might also be divided, some might be against it because of the long - standing rivalry between the Gryffindors and Slytherins, while others would see it as a chance for unity in the wizarding world.
In fanfiction, the idea of Hermione being pregnant with twins at Hogwarts can lead to a lot of interesting character developments. Her friends, like Harry and Ron, would likely have to step up and support her. And the Hogwarts faculty might be in a quandary about how to handle a pregnant student. There could also be a mystery surrounding the father of the twins, or perhaps it's a magically - induced pregnancy due to some dark or light magic experiment gone wrong.
The story could also focus on the relationship between Hermione and Draco. At first, there might be a lot of tension and mistrust. Draco might be resistant to being 'adopted' by Hermione, a Muggle - born. But as time passes, they could start to understand each other. Hermione could help Draco with his schoolwork, especially in areas where he struggles like Potions (since Hermione is excellent at it). In turn, Draco might share some of the secrets of the Slytherin common room or some of the Pure - blood family politics that Hermione was previously unaware of.
If they were twins in fanfiction, Draco could have a complete transformation. He might start to secretly help Hermione with her campaigns for the rights of Muggle - borns, which would be a huge shift from his character in the original story. Hermione could also change. She could become more protective of Draco, especially when he faces backlash from his pure - blood family for his new - found views. Their relationship could be a central focus of the fanfiction, with both of them growing together and learning from each other. This would create a really interesting dynamic as they are from such different backgrounds within the wizarding world.
There could be a situation where Draco has a change of heart later. Maybe he realizes his mistake after some time away and tries to come back into Hermione's life. This could lead to a very emotional and complex reunion, with Hermione having to decide whether to forgive him or not.
One way could be through a time - travel or alternate - reality plot. Maybe in a different timeline, the rules at Hogwarts are different, and Hermione and Snape form an unexpected bond. Then, an accident or a magical mishap could lead to her pregnancy. But it would have to be carefully crafted to make it somewhat believable within the fanfiction world.
If Hermione and Draco were siblings in fanfiction, it would completely turn the original story on its head. For one, Hermione's Gryffindor nature and Draco's Slytherin one would create a really interesting family dynamic. Their parents must have had a very complex relationship for this to be possible. It could lead to Hermione having a different view of the wizarding world from the start. Instead of being a Muggle - born advocate in the way she was, she might have had some internal conflict due to her Slytherin - influenced family ties. And Draco might not be as much of a bully as he was originally, or at least he would have a different kind of relationship with Harry, Ron, and Hermione.
If Draco steals Hermione from Ron in fanfiction, it might show a different side of Hermione. She might be attracted to Draco's intelligence in a different way than Ron's loyalty. This could lead to new magical adventures where Hermione uses her knowledge in a more Slytherin - like way, influenced by Draco. It could also make for some interesting interactions between the Gryffindors and Slytherins, as now there's a connection between them through Hermione. The story could explore how love can cross house boundaries in a more extreme way than what we see in the original books.
