The Dark Mark could be a catalyst for their relationship to become a very complex and passionate one. They might be constantly at odds with each other because of their different views on how to handle the situation of the Dark Mark. However, these arguments could also lead to a deeper understanding. Draco's internal struggle with his past and Hermione's quest for knowledge and justice would collide and merge. Through this process, their relationship would develop from enmity to a sort of grudging admiration, and eventually to love as they realize they are better together in facing the mystery of the Dark Mark.
In the context of the Dark Mark, they could develop a relationship based on mutual protection. As they try to figure out what the Dark Mark means in the new situation, they become each other's protectors. Draco could use his knowledge of the wizarding underworld to keep Hermione safe, and Hermione could use her intelligence and magical skills to shield Draco from the suspicions of others. This would create a bond between them that gradually turns into something deeper, like love.
In this context, at first they would be full of resentment. But as they have to live together and follow the Marriage Law, they would start to notice small things about each other. Draco might be impressed by Hermione's determination in handling household magic in a different way than he's used to. Hermione could see Draco's loyalty to his family in a new light. This could lead to a cautious friendship that over time might turn into something more romantic.
It could also be that they are initially enemies within the Death Eater world. But as they witness the atrocities committed by the Death Eaters, they both have a moment of realization. Draco, having grown up in that world, and Hermione, seeing it from an outsider's perspective. This shared experience could lead to a begrudging respect that then blossoms into a deeper relationship as they try to find a way out of the dark world they've found themselves in.
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.
In some fanfictions, Hermione and Draco become friends through mutual understanding. Maybe they start to see beyond their house rivalries at Hogwarts. For example, they could be forced to work together on a special project for the school. At first, they might be hostile, but as they get to know each other's true selves, a friendship begins to form.
In fanfiction, Draco's connection to the Dark Mark often serves as a source of internal conflict. Writers explore how he grapples with the mark's implications and his family's ties to the Dark side. It can be a powerful device to show his character development.
One plot idea could be that Draco discovers Hermione has a connection to the Dark Mark against her will. Maybe she was cursed with it during an encounter with Death Eaters. Draco, having some knowledge of the Dark Arts, decides to help her get rid of it secretly, which would lead to many tense and secretive meetings between them as they try to figure out how to break the curse without getting caught by either side.
In many of these fanfictions, their relationship starts off rocky. They're forced into this marriage situation, and at first, they can't stand each other. But as time goes on, they start to communicate more. Small things like sharing a meal or discussing their daily lives break the ice.
At first, their relationship might be full of tension. Draco is used to the pure - blood ideology of Slytherin and Hermione is a Muggle - born. But as they spend more time together, they start to see each other's good sides. For instance, Draco might notice Hermione's determination and loyalty, which are also Slytherin traits in a way.
At first, their relationship might be full of confusion and denial. Draco, coming from a pure - blood supremacist family, would struggle to accept a Muggle - born sister. Hermione, on the other hand, would be shocked but also curious. As time goes by, they might start to secretly help each other. For example, Draco could give Hermione some insights into the Slytherin way of thinking, and Hermione could help Draco with his studies.
In this fanfiction scenario, their relationship would be a journey of discovery. Hermione would bring her logical thinking and knowledge, while Draco would contribute his knowledge of the wizarding elite society. Initially, they would be at odds, but as they spend more time together at work, Draco might open up about his insecurities regarding his family's past actions. Hermione, in turn, would start to empathize with him. This sharing and understanding would gradually develop into a strong bond between them.
