A possible storyline is them teaming up to solve a mystery related to their family. Maybe their parents were involved in something before they were born, and now Draco and Hermione have to follow the clues. In some fanfictions, they find that their family has a connection to an ancient magic. They start to learn about their family's past together, and along the way, they overcome their initial differences. Draco's Slytherin cunning and Hermione's Gryffindor bravery combine to make them a formidable duo when it comes to unravelling the secrets.
Well, there could be a storyline where they are reunited as siblings in a time - travel scenario. They get sent back in time and find out that their parents were friends in their youth. This leads to Draco and Hermione being born earlier in a different timeline and having to adjust to being siblings in this new situation. They have to use their knowledge of the future to prevent some dark events from happening while also dealing with their new family relationship. It's a unique take on the idea of them as siblings.
Hermione would likely become more understanding of Draco's situation. In the original stories, they were enemies. But as siblings, she would see the pressures he was under from his family. This could lead to her being more empathetic. Draco, on the other hand, would probably have to tone down his arrogance. With Hermione as his sister, he'd be constantly challenged. He might start to show more humility, like in one fanfiction where he apologized to Harry and Ron for his past behavior because Hermione made him realize how wrong he was.
One common plot twist is the revelation of a hidden family connection that makes them siblings. Another could be that they have to team up against a common enemy, like a dark wizard who is targeting their family. It might also be that Draco has to choose between his Slytherin friends and his new - found sister Hermione when there's a conflict between them.
Often, in such fanfictions, there are plots where Hermione tries to keep the pregnancy a secret from the wizarding community at large. She might fear the reaction from both the Gryffindor and Slytherin sides. There could also be a storyline where Draco, despite leaving, has second thoughts later in life and tries to come back into Hermione's and the child's life, creating a lot of emotional turmoil.
A great storyline could be the daughter having a unique magical ability that neither of her parents have. This could lead to her being both feared and admired at Hogwarts. In some fanfictions, she uses this ability to solve mysteries around the school. There could also be a story where she has to choose between following the Slytherin or Gryffindor values more closely, as she has a connection to both through her parents. This internal struggle can make for a very engaging read. And of course, a plot where she gets involved in a time - travel adventure related to her parents' Hogwarts years would be really exciting.
One popular storyline is the 'enemies - to - lovers' trope. Draco starts off hating Hermione as in the original series, but gradually falls in love with her through various encounters. For example, they might be forced to work together on a project for Hogwarts and start to see each other in a new light.
One great Draco and Hermione fanfiction is 'Manacled'. It presents a very complex and engaging story where the relationship between them develops in a unique post - war setting. The characters are well - written and it keeps you hooked from start to finish.
One interesting storyline could be a time - travel plot where Hermione and Draco are sent back in time and have to work with Hogwarts professors from different eras to fix a major magical disruption. For example, they might have to team up with Professors Dumbledore and Snape in the past to prevent a dark wizard from changing the course of wizarding history.
Perhaps a storyline where Draco and Hermione's daughters are at Hogwarts and are part of a new generation trying to bridge the gap between the houses. Their daughters could start a club or an initiative that promotes unity among the different houses, much like their parents overcame their own house differences. They might face opposition from some traditionalists who still believe in the old rivalries, but they persevere.
One popular storyline could be that Draco and Hermione are forced to work together on a secret mission in the night club setting. Maybe there's a dark wizard threat that only they can solve due to their combined knowledge and skills. Another could be that they accidentally meet at the night club and start a friendly rivalry that slowly turns into something more romantic as they get to know each other better. A third one might be that they both attend the night club for different reasons, Hermione for some sort of academic research on the social behavior of wizards at such places and Draco just for leisure, and their paths cross in an unexpected way that changes their relationship dynamic.
One possible storyline could be that their children inherit the best of both worlds. For example, they might have Draco's Slytherin cunning and Hermione's Gryffindor bravery. They could be the bridge between the former Slytherin - Gryffindor rivalry, using their combined skills to solve new magical mysteries at Hogwarts. Maybe they'd form new friendships across houses that were previously unthinkable due to their parents' history.
