One interesting plotline could be Draco trying to redeem himself in the wizarding world post - Hogwarts. He might start by using his family's wealth and influence for good, like funding charities for those affected by the war. Another could be his struggle to find true friendship outside of the Slytherin clique he was part of at school. He could also be on a journey to discover a new type of magic that was previously unknown to him, perhaps something that can help heal the divides in the wizarding community.
Some plotlines might involve Draco's career choices after Hogwarts. He could decide to become an Auror, despite his family's dark past, to prove that he has changed. Or he could go into business, using his knowledge of potions to start a new line of magical products. There could also be a plot where he is forced to confront his past actions during the war and has to make amends to those he wronged, which could lead to all sorts of adventures and self - discovery.
One possible plotline could be a comical misunderstanding. Maybe there's a spell gone wrong that causes some sort of diaper - related chaos in Hogwarts. For example, a spell meant to clean the corridors accidentally turns Hermione's books into diapers and Draco gets blamed for it, leading to a series of events where they have to work together to fix the situation.
One interesting plotline could be their struggle to overcome the prejudices of their respective Houses. Since Draco is from Slytherin and Hermione from Gryffindor, their marriage would shock many at Hogwarts. They might face opposition from their old friends and families. Another plotline could be them working together to improve the relations between Muggle - borns and pure - bloods. Draco, with his pure - blood background, and Hermione, as a strong advocate for Muggle - born rights, could make a powerful team in the wizarding world's fight against blood - based discrimination.
A great plotline in these fanfics can be the integration of new magical creatures into the post - battle Hogwarts. With the upheaval of the battle, magical barriers might have weakened, allowing new creatures to enter. The students and teachers then have to figure out how to co - exist with them. There could also be a story about the Muggle - born students trying to bridge the gap between the wizarding world and the Muggle world more than ever, as they've seen the destruction that secrecy can bring.
One possible storyline could be that Draco is put under a spell that makes him revert to a baby - like state and needs to wear diapers. This could lead to humorous situations as his Slytherin pride clashes with his newfound helplessness. Another could be a time - travel plot where Draco has to take care of his younger self who is in diapers, and he learns about himself in the process.
One interesting plotline could be their rivalry evolving into an unexpected friendship. Maybe they find out they have more in common than they thought when facing a common enemy at Hogwarts, like a particularly difficult dark magic creature that threatens the school.
In this fanfiction, perhaps there are magical creatures that are drawn to the graveyard for some unknown reason. The students might try to befriend these creatures to understand why they are there. It could also involve a new spell or magical object that is related to the graveyard and Hogwarts students are on a quest to find it.
One interesting plotline could be the culture clash between Smeltings and Hogwarts. Since Smeltings is known for its strict and perhaps more traditional ways compared to Hogwarts' more inclusive and magical diversity. For example, a Smeltings student might struggle to adapt to the use of magic for everyday tasks at Hogwarts, like using a levitation charm instead of doing things manually as they were taught at Smeltings.
One interesting plotline could be Harry discovering ancient magic secrets related to his status as heir. Maybe he finds a hidden chamber in Hogwarts that only the heir can access, filled with powerful spells and artifacts.
Well, perhaps a plotline where Harry has to deal with a new dark threat that is targeting Hogwarts specifically. As headmaster, he would use his knowledge of the Dark Arts and his friends' expertise to protect the school. He could also start new traditions at Hogwarts to boost the morale of students and staff alike.
Another interesting plot is when they are both part of a magical competition. They start as rivals but end up learning from each other. In one particular fanfiction, they are in a dueling tournament. Through the duels and the preparation for them, they see each other in a new light and form an unexpected bond.
