One possible reason could be that Draco is scared of the responsibility. He might come from a family with certain expectations and the idea of having a child with Ginny, who is from a different side in the wizarding world, could be too much for him to handle.
One possible reason could be miscommunication. Maybe they had a big fight over how to raise their child and Ginny, feeling unheard, decided to leave. Another reason might be external pressure. For example, if some dark forces were targeting their family again and Ginny thought leaving would keep Harry and the child safer. Or perhaps Ginny had some personal issues she couldn't deal with while being in the family, like feeling she lost her own identity in the relationship.
In this fanfiction, Ginny might find strength within herself that she didn't know she had. She could start to form new relationships with other characters who help her through the pregnancy. For example, she could become closer to Hermione, who could offer practical and emotional support. The pregnancy could also be a catalyst for changes in the wizarding society's view on single motherhood. It could lead to new laws or social norms being established, and Ginny could be at the forefront of this change.
Ginny might first be in shock and denial. But then she could draw on her Gryffindor courage. She would probably turn to her family for support. The Weasleys are a close - knit family, and they would surely rally around her, providing emotional and practical help.
One possible reason could be a misunderstanding. Maybe there was a miscommunication between them, like Ginny thought Harry was still too preoccupied with his past traumas and not fully committed to their relationship. Another reason might be external pressure. In some fanfictions, there could be outside forces, such as dark wizards threatening Ginny and she leaves Harry to protect him.
There are several possible reasons. Draco might be trying to assert his superiority. Since Ginny is from a 'blood - traitor' family in his view, he could be making fun of her to show that he thinks he's better. Also, he could be doing it to get a reaction from Harry. By taunting Ginny, he knows it will likely anger Harry, which might be part of his plan in the fanfiction.
One possible reason in such a fanfiction could be a magical bond that forms between Harry and Draco unexpectedly. This bond might be stronger than his relationship with Ginny. It could be a result of a shared magical experience or a prophecy that ties them together in a way that makes Harry question his feelings for Ginny and ultimately choose Draco.
Well, in this kind of fanfiction, a plot development could be that Ginny, being pregnant, discovers new magical abilities or powers related to motherhood. This could be a unique take on the story. Also, the wizarding community might react in different ways to Ginny's situation. Some could be supportive, while others might shun her because of Harry's departure. It could lead to Ginny having to fight for her place in the community and prove that she can be a great mother on her own terms.
Well, it could be that Ginny is pregnant in a world where magic exists (assuming this is related to a magical universe like Harry Potter if Ginny is from there). The pregnancy could bring about some sort of magical phenomenon. Maybe the unborn baby has some sort of special power that starts to manifest during the pregnancy. This could lead to Ginny having to protect the baby from those who might want to use the baby's power for their own gain. At the same time, Ginny has to deal with the normal physical and emotional aspects of pregnancy like morning sickness and mood swings.
One possible plot could be that Harry and Ginny are overjoyed at the news of Ginny's pregnancy. They start preparing for the baby's arrival by setting up a nursery in their home at Grimmauld Place. Ginny might take a break from Quidditch, and Harry would be extra protective, constantly worrying about her safety. Their friends like Hermione and Ron would be excited and offer their help, bringing baby clothes and giving advice based on what they've read in wizarding parenting books.
One possible reason could be that Harry realizes he has stronger emotional and intellectual compatibility with Ginny. He might find that Ginny understands his complex life as a wizard better, especially with her own experiences in the wizarding world. Also, Ginny is more in tune with Harry's adventurous spirit, which Cho might not be as much.
