Perhaps a fanfiction where a character's skirt becomes a symbol in a story involving Draco at Hogwarts. For example, a girl with a unique skirt is part of a prophecy or something similar. And the term 'whore' is misused by some jealous students against her. Draco, initially believing the rumors, later realizes his mistake and helps her against the bullies at Hogwarts.
One possible storyline could be a story where a character in a skirt has an unexpected encounter with Draco at Hogwarts. Maybe she's a new student who catches his eye, and there's a bit of a mystery about her that makes him initially suspect she might be a 'whore' in the sense of having a secret or being different from what she seems. But as the story unfolds, they find common ground and develop a friendship or more.
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.
In a fanfiction, we could have a situation where a character's skirt is enchanted. Draco, being the curious Slytherin he is, gets involved in the mystery around it. The 'whore' concept could be turned into a false accusation made by a rival group in Hogwarts. The story could revolve around Draco and the character with the skirt proving their innocence and also showing the power of true friendship in the face of false rumors at Hogwarts.
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.
One idea could be Hermione being wrongly accused of a rule-breaking at Hogwarts and as a form of 'punishment' she has to wear a special collar that has some magical properties. For example, it might restrict her magic usage in certain areas of the castle until she proves her innocence. Another plot could involve a mysterious group at Hogwarts that uses collars as a symbol of membership and Hermione gets caught up in it while trying to expose their true motives.
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.
Perhaps a story where Mudbloods at Hogwarts start a secret club to support each other. They could share their experiences of dealing with the prejudice, study magic together in unique ways, and eventually gain recognition for their contributions to the school. This would show their strength and unity in the face of adversity.
Another possible storyline is that they become friends after an accident. Maybe during a Quidditch match, there's a terrible accident and they have to rely on each other to survive. This shared experience makes them see each other in a new light and they start to build a friendship. They then help each other deal with their respective family issues. Draco can give Harry insights into the pure - blood families' ways, and Harry can show Draco a different way of looking at the world, not just through the pure - blood ideology.
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 idea could be Draco being sorted into a different house by mistake. Maybe the Sorting Hat has a moment of confusion and puts him in Hufflepuff. This would lead to him having to adjust to the very different values and atmosphere of that house, and it could be a journey of self - discovery as he realizes there's more to life at Hogwarts than just the Slytherin way.
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.
