At first, they would be very distrustful of each other. Harry might suspect Draco of having some hidden motives, and Draco would be cautious around Harry. But as they face difficulties like finding food and shelter during their escape, they would start to rely on each other. Eventually, they could become friends or at least comrades in their situation.
Draco's character could develop from a somewhat arrogant and prejudiced boy to a more empathetic and self - aware person. Being with Hermione, who constantly challenges him intellectually and morally, would force him to grow. Hermione would also develop in terms of her relationships. She would learn to trust someone from a different background and perhaps become more rebellious against the norms of the wizarding society that have been holding her back in some ways.
One possible plot could be that they run away to escape the ongoing wizarding war. They find a secluded place, perhaps a hidden cottage in the Forbidden Forest. There, they start to understand each other better without the influence of their respective houses' prejudices. They might discover new magic together and form a bond that is deeper than friendship.
One possible reason could be a conflict of values. Hermione is a strong advocate for justice and equality among wizards and non - wizards alike. Draco, on the other hand, was brought up in a family with pure - blood supremacist views. Hermione might run away from Draco in a fanfiction if she realizes that his views are unchangeable and they are fundamentally opposed to her own. For example, if Draco makes a derogatory comment about Muggle - borns in front of her, it could be the last straw and she decides to run away.
They might run away because they want to explore the wizarding world on their own terms. Without the restrictions of Hogwarts or the watchful eyes of the Ministry of Magic.
The storyline might then take different directions. For example, Hermione running away could lead her to new adventures on her own. She could discover new magical abilities or meet new characters who will help her grow. Meanwhile, Draco might have his own character development as he reflects on why Hermione left. He could either become a better person trying to win her back or turn even more bitter. Overall, it can greatly diversify the plot.
At first, their relationship would be very tense. They have a long history of animosity from their Hogwarts days. But as they run away and are forced to rely on each other, they start to see each other in a new light. Draco might start to admire Hermione's intelligence and determination, while Hermione could come to understand the pressures Draco faced from his family. This new - found understanding could lead to a cautious friendship, which gradually turns into something more romantic as they share more personal stories and experiences.
Well, perhaps they run away to escape the chaos at Hogwarts. Maybe they've discovered a dark secret within the school that puts their lives in danger. So they decide to flee and find a hidden place in the Forbidden Forest to stay safe.
One possible plot could be that they run away to escape the dark forces that are taking over the wizarding world. They might be on a quest to find a powerful magical artifact that could turn the tide of the battle. Along the way, they face various challenges like dangerous creatures and spells.
Voldemort and his Death Eaters would be obvious antagonists. They could be constantly hunting for Harry and Tonks as they are seen as threats to Voldemort's plans for total domination of the wizarding world.
