The relationship could develop as a result of a common goal. Let's say there's a competition between the houses, and Draco and Neville both realize that winning it would benefit Hogwarts as a whole. They put aside their differences and start to strategize together. Along the way, they discover that they have more in common than they thought. Draco's ambition and Neville's determination blend well, and they form a bond that grows stronger as they work towards the goal.
In the fanfiction, it could develop through shared experiences. Maybe they both get involved in a dangerous situation in the Forbidden Forest. Draco is used to relying on his own wits, but Neville's kind heart and loyalty make him a valuable ally. As they fight off dark creatures together, they start to see each other in a new light. Draco begins to respect Neville's tenacity, and Neville sees that Draco is more than just a snobbish Slytherin.
Perhaps a plot where Draco and Neville are both caught in a magical mystery outside of Hogwarts. They have to rely on each other to survive. Draco's Slytherin cunning helps them avoid some dangerous traps, while Neville's Gryffindor courage gives them the strength to face the unknown threats head - on. As they go through this adventure, they develop a bond that surprises their friends back at school, and they end up changing the views of their respective houses about the other.
In many of these fanfictions, Draco often starts as a more guarded character. But as Neville's pregnancy progresses, he becomes more protective and caring. For example, in 'The Unlikely Bond', he gradually sheds his Slytherin cold - exterior. Neville, on the other hand, grows in confidence. His pregnancy makes him more assertive about his relationship with Draco.
I really like 'Draco's Redemption and Neville's Forgiveness'. In this fanfic, Draco is trying to make up for his past wrongs during the war, and Neville is the one who helps him through it. It delves deep into their emotions and how they grow as characters through their interactions.
Their relationship could develop in a rather complex way. At first, they may be shocked by the pregnancy. But then, as they face the reality together, they find themselves falling in love. Neville could become more protective, and fem Harry could see a side of Neville she never noticed before. They would grow through shared experiences like preparing for the baby's arrival, dealing with family reactions, and facing the wizarding society's judgment.
One great 'Harry Potter' fanfiction with Neville and Draco is 'The Unlikely Bond'. In it, they are forced to work together on a school project. At first, they clash due to their different personalities and house loyalties. Draco is his usual snobbish self, while Neville is shy but determined. As the story progresses, they start to understand each other better. Neville shows Draco the importance of kindness and hard work, and Draco helps Neville become more confident in standing up for himself.
At first, they might be shocked and a bit confused about being twins. But as time goes on, they start to trust each other more. They could share their secrets and fears, like Harry might tell Draco about his nightmares of Voldemort, and Draco might open up about the pressure from his family.
Another interesting plot is when they are both part of a magical competition. They start as rivals but end up learning from each other. In one particular fanfiction, they are in a dueling tournament. Through the duels and the preparation for them, they see each other in a new light and form an unexpected bond.
I really like 'The New Alliance'. In this fanfiction, Neville and Draco team up to fight against a new dark force that emerges in the wizarding world. Their partnership is unexpected but it works really well. Draco uses his family's resources and Neville uses his Gryffindor courage. It's a fast - paced story full of action and adventure.
Another option is to check out some Harry Potter - themed fanfiction communities on social media platforms. Sometimes, members share their own works or recommend great fanfictions. For example, on Tumblr, there are often fanfic recs that could lead you to dominant Neville and submissive Draco stories.
In some fanfictions, there could be a slow - burn development. Hermione might initially despise Draco for his cruel remarks and actions. But then she starts to notice his insecurities and the pressure he is under from his family. Draco, on the other hand, might be attracted to Hermione's intelligence and courage. This gradual realization of each other's qualities builds a relationship that is fraught with the pain of their past interactions and the difficulty of changing their established opinions.
