You can try fanfiction websites like Archive of Our Own (AO3). There are a large number of Astoria and Draco fanfictions there. Just search for their names in the search bar and you'll get a long list of stories to choose from.
Another option is to check out some Tumblr blogs dedicated to Harry Potter fanfiction. There are often reblogs of really interesting Astoria and Draco stories. You can also interact with other fans there and ask for recommendations. They might be able to point you to some hidden gems that are not as well - known on the bigger platforms.
You can start by looking on fanfiction platforms like FanFiction.net or Archive of Our Own (AO3). Just search for 'Draco Astoria baby Scorpius' on their search bars, and you'll get a list of relevant stories. Some stories might focus on the family dynamics, like how Draco and Astoria raise Scorpius, while others could be more about adventures with a young Scorpius in the wizarding world.
Another good one is 'Love in an Arranged Bond'. This story delves deep into the emotional turmoil of both Draco and Astoria. Astoria is a bit more open - minded about the marriage from the start, but Draco is resistant. As the story progresses, they start to share their secrets and fears with each other, which ultimately brings them closer together. The descriptions of their Hogwarts - like surroundings also add to the charm of the story.
Fanfiction.net is also a great place to search for such fanfictions. There are many authors who write about these characters. However, the quality can vary, so you might need to read a few summaries and reviews before choosing which ones to read. You could also join some Harry Potter - related fan groups on social media platforms and ask for recommendations from other fans.
In my experience, Reddit has some hidden gems when it comes to this type of fanfiction. There are subreddits dedicated to Harry Potter fanfiction. You can post a request for Draco Malfoy and Astoria Greengrass fanfics, and often the community will come through with some great suggestions. You might also want to check out some of the smaller, more niche fanfic websites that focus specifically on Harry Potter.
I also like 'The Malfoy Family Ties'. This fanfiction gives a detailed look into the daily lives of the Malfoy family. Draco is shown as a more complex character, trying to be a good father. Astoria is depicted as a loving mother, and Scorpius is just an adorable child caught in the middle of the family's growth and change. It's a great exploration of their family dynamics.
In some versions, Astoria is often depicted as more of a free spirit. She may introduce Draco to a new way of life that he finds exciting. Her charm and grace could also be factors. She might be the kind of person who doesn't put pressure on Draco like Hermione might have, in terms of his past actions or family history. This lack of judgment makes Draco feel more comfortable around her.
One great Draco and Astoria pregnant fanfiction is 'A New Beginning' which beautifully depicts their journey into parenthood. It shows Draco being very protective and Astoria handling the pregnancy with grace.
In some Dramione fanfictions, there might be such a plotline where Astoria cheats on Draco. However, it really depends on the specific fanfiction. Different authors may have different interpretations and story developments.
One possible aspect in this fanfiction could be the initial encounters between Draco and Astoria. Maybe they meet at a pure - blood event, where Draco, who has changed a lot after the war, is drawn to Astoria's kind and intelligent nature. Astoria, on the other hand, might see through Draco's past mistakes and recognize the person he is trying to become. Their love could develop gradually as they share secrets and experiences, slowly realizing that they are meant for each other.
Draco and Astoria's love in fanfiction is often depicted as a journey of two souls finding each other. In many stories, Draco, who has a complex past, is shown to be redeemed by Astoria's love. Their relationship starts with a simple encounter, perhaps in a wizarding ball or in a quiet corner of Diagon Alley. Astoria, with her kind heart, sees beyond Draco's former Slytherin bravado. Their love then blossoms as they share secrets, dreams, and fears. They might go on adventures together, facing dark wizards or solving mysteries within the wizarding world. Their love is not only about passion but also about mutual understanding and growth.
