One popular plotline could be that the ring has some sort of magical property that binds Draco and Hermione in an unexpected way. For example, it might make them share thoughts or emotions, leading to a deeper understanding of each other despite their initial differences. Another could be that the ring is a family heirloom of Draco's, and by some turn of events, Hermione comes into possession of it, which causes a stir in the wizarding world as it's seen as a symbol of ownership over her in some archaic sense, but they end up working together to break the strange bond it represents.
Often, the plot might involve the ring being enchanted by a dark wizard long ago. Draco discovers the ring first and when Hermione accidentally touches it, she becomes linked to him. They then have to go on a quest to find a way to remove the ring's power. This journey forces them to rely on each other, and in the process, they start to see the good in one another. It could also be that the ring is part of a prophecy that involves their union, which both initially resist but as the story unfolds, they come to accept it.
A popular plotline is the redemption arc for Draco. In these fanfictions, Hermione might be the catalyst for his change. He realizes the error of his ways under the influence of her strong moral compass. There could also be a plotline where they are competing for the same goal, like a powerful magical artifact. As they hiss and argue throughout the competition, they gradually develop feelings for each other. Also, some fanfictions have a plot where they are both involved in a dangerous situation outside of Hogwarts, like in the wizarding underworld, and they have to rely on each other to survive.
The 'owner ring' often creates a forced connection. It can start as a source of conflict as Hermione may resist the idea of being 'owned' by Draco. But it also means they have to interact more, which can lead to a grudging respect and eventually deeper feelings. For example, if the ring gives Draco some power over Hermione's actions, she'll fight against it at first but then they might find common ground.
A frequently seen plotline is the arranged marriage one. In these fanfictions, the wizarding world's old - fashioned ways force Draco and Hermione into an arranged marriage. At first, they resist but as they get to know each other better, they fall for each other. There are also plotlines where they are competing for the same powerful magical artifact. During their rivalry, they start to respect each other's skills and intelligence which then turns into attraction. And sometimes, fanfictions have a plot where Draco saves Hermione from a dark wizard and this heroic act makes Hermione re - evaluate her feelings for him.
One interesting plotline could be that Draco and Hermione are forced to work together in a post - war magical reconstruction project. As they spend time together, they start to see each other in a new light and gradually fall in love. Eventually, they rise to become king and queen - like figures in the wizarding world, leading with a new sense of unity.
In some fanfictions, the baby is born in a time of danger. There could be dark wizards still out there who want to harm the baby because of its significance. This forces Hermione and Draco to go into hiding and rely on each other for protection. The baby then becomes a source of strength for them, and they grow closer as they fight to keep their family safe. This kind of plotline adds a lot of action and adventure to the story.
One common plotline is Draco secretly helping Hermione during the Triwizard Tournament. Maybe he warns her about certain dangerous tasks or provides her with a bit of insider knowledge on the challenges. Another plotline could be in a post - war scenario where Draco, trying to make amends for his past, offers his assistance to Hermione in rebuilding Hogwarts or in dealing with the remaining Death Eater threats. There are also plotlines where they are paired up for a school project and Draco, against his family's beliefs, decides to help Hermione succeed.
In some fanfictions, the plotline involves Hermione getting a tattoo that has a hidden meaning only Draco can understand. This leads to Draco being intrigued by her and trying to figure out why she got it. As he delves deeper, they start to develop feelings for each other. Another idea is that they get matching tattoos during a time - traveling adventure. They are forced to work together in a different era and the tattoos become a symbol of their bond. Also, there could be a plot where Draco is forced to get a tattoo as a punishment and Hermione, out of her kindness, helps him deal with it, which starts a whole new relationship between them.
Some fanfictions focus on the Sorting Hat ceremony in their first year. What if the Sorting Hat had a moment of indecision between Gryffindor and Slytherin for Hermione or Draco? For Hermione, it could consider her ambition and intelligence which are also traits of Slytherin. For Draco, it might see a glimmer of courage or a different side to him that could fit in Gryffindor. This moment of near - mis - sorting could be the start of an alternate universe type of fanfiction where their relationship develops in a very different way from the original story.
Often in this type of fanfiction, there's a power dynamic at play. Draco, being from a pure - blood family, might think he has the right to have Hermione as his pet. But Hermione, being the strong - willed character she is, will constantly fight against this. This creates a lot of conflict and drama. There could also be a plot where the other Hogwarts students find out about this strange relationship and either try to rescue Hermione or are confused by the change in Draco's behavior towards her.
One popular theme could be the idea of redemption for Draco. In many fanfictions, he is shown to overcome his family's dark past and prejudice. Another theme might be the power of friendship or love that develops between Hermione and Draco, despite their initial differences. It could also explore how they navigate the complex wizarding world together, facing challenges from their respective houses and the general wizarding society.
