Well, perhaps the story is set in a post - war scenario. The wizarding world is in a state of rebuilding, and Draco is ostracized due to his family's actions during the war. Hermione, being the empathetic person she is, takes him in. She might face a lot of opposition from the wizarding community, but she doesn't care. In the fanfic, their relationship could develop in an interesting way, like Draco learning about Muggle - born rights from Hermione and starting to fight for equality himself.
One possibility could be that in the wizarding world, Hermione, known for her kind heart and strong sense of justice, sees Draco in a vulnerable state. Maybe his family has fallen from grace and he has no one to turn to. Hermione decides to adopt him as a way to show that people can change and grow. She could introduce him to her way of life, filled with books and learning, and Draco would slowly start to adapt and become a better person under her influence.
At first, their relationship is likely to be tense. Draco is used to a certain way of life and Hermione has her own strong - willed nature. But as time passes, Draco starts to respect Hermione's intelligence and kindness. Hermione, in turn, sees Draco's vulnerability and the potential for good in him. Their relationship gradually becomes one of mutual understanding and support.
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.
The story could also involve Hermione using her magical knowledge to help Tom control his powers. Since Tom is a powerful wizard from a young age, he might have difficulty handling his magic properly. Hermione, being a brilliant witch, could guide him. This could lead to a unique bond between them, where Tom respects Hermione for her abilities and Hermione sees the potential for good in Tom.
One possible storyline could be that Hermione, having witnessed the hardships of war and the many orphaned children, decides to adopt a child. She might choose a child who shows magical potential but has been overlooked in the post - war chaos. The story could then focus on her struggles and joys of raising the child while also dealing with her own career and the expectations of the wizarding world.
Draco would likely become more open - minded. Growing up in a rather closed - off pure - blood family, being adopted by Hermione would expose him to different ideas. He might start to question the long - held beliefs of his family. For instance, he could become more accepting of Muggle - borns, like Hermione herself.
One way this could develop is through a dark magic plot. Maybe Draco is under some sort of spell or family obligation that he thinks can only be fulfilled by marrying Hermione. He might use threats against her friends or family in the fanfic to force her into the marriage. However, Hermione being the strong - willed character she is, would constantly be looking for a way to break free from this forced union.
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.
It could be a plot where Draco and Hermione are forced into a situation where they have to rely on each other's knowledge. Their 'tongue' in this case might refer to their quick - wittedness. For instance, they might be in a magical maze and need to solve puzzles by using their combined intelligence, which then leads to a new - found respect for each other.
One possible plot could be that Hermione is captured and brought to the Malfoy Manor. Draco, having some internal conflict due to his growing feelings for Hermione despite their past enmity, tries to protect her from the other Death Eaters in the Manor. Maybe they end up having to work together to escape some dark magic trap set within the Manor.
