Well, it could be a really strange and unique plot. Maybe it's a story where Astoria has some sort of condition that requires her to wear nappies and Harry is somehow involved in her life during this situation, perhaps helping her deal with the embarrassment or challenges that come with it.
It might be a humorous take on the Harry Potter universe. The fanfiction could be about Astoria wearing nappies as a result of a magical mishap. For example, a spell gone wrong made her regress to a state where she needed nappies, and Harry, being the hero he is, tries to find a way to reverse the spell while also having some comical interactions with her in this awkward situation.
Another possibility is that it's a more serious and emotional story. Astoria wearing nappies could be a symbol of her vulnerability. Maybe she's ill or injured, and Harry comes to support her. This could explore themes of friendship, acceptance, and how people deal with difficult and embarrassing situations in the wizarding world. Harry's presence could show his kindness and compassion towards her.
Obviously, Astoria and Harry are likely to be the main characters. Astoria is the one with the unique situation of wearing nappies, and Harry is probably there to interact with her in some way, whether it's as a friend, a helper, or something more.
Well, it could be about Astoria showing great respect or submission to Harry for some heroic deeds he has done. Maybe he saved her life or the wizarding world in a way that made her feel indebted and thus kneel before him.
A plot could revolve around their family life. They would face the challenges of combining two different family legacies. Harry, being the famous Boy Who Lived, and Astoria from the Greengrass family. Their children might inherit unique magical abilities and face their own set of challenges in Hogwarts, and the fanfiction could explore how Harry and Astoria guide them through it all. It could also deal with how they navigate the social expectations of the wizarding society as a married couple.
Well, consider this. In the wizarding world, there are rumors of a powerful lemon - enchanted artifact. Astoria Greengrass is intrigued by it and sets out to find it. Harry Potter, being the hero he is, gets involved too. As they search, they face many obstacles, like dark magic traps. Their relationship develops as they rely on each other's skills. Astoria's knowledge of ancient magic and Harry's courage work in tandem. And the lemon - enchanted artifact could hold the key to saving the wizarding world from a new threat, or it could be something that changes their lives in a more personal way, like giving them a new magical ability related to lemons.
In this fanfiction, Harry might be transported to a parallel magical world in Japan while wearing the kimono. There, he has to adapt to the different magical customs and traditions. He could meet Japanese wizards and witches who help him on a quest to find a way back to his own world. Along the way, he learns about the significance of the kimono in their culture and how it can be used as a magical tool.
One possible plot could be that Harry is trying to fit in with a new group of wizard friends who are into a more punk - rock or alternative style. Wearing eyeliner is his way of showing that he belongs with them and is embracing a different side of himself.
The plot could involve Astoria being a key figure in a movement to reform certain archaic wizarding laws. Harry, being a symbol of change, gets involved too. They work together closely, and Harry is impressed by Astoria's intelligence and determination. Astoria, on the other hand, admires Harry's courage. Their relationship blossoms as they fight for a better wizarding world. And finally, they decide to get married, with their wedding being a grand event that symbolizes a new era of unity and progress in the wizarding community.
Perhaps it could be set in an alternate universe where Harry is a baby and the wizarding world is facing a threat that only baby Harry can solve because of a special power he has that is related to his diaper. The diaper could be enchanted in some way, and throughout the story, Harry's innocent actions while wearing it end up having a big impact on the events in the wizarding world. This would be a fun and light - hearted plot without being offensive.
One possible plot could be a post - war scenario. Draco, having redeemed himself to some extent, meets Astoria at a pure - blood gathering. Their initial encounter is filled with a bit of tension as they come from different yet similar backgrounds. As they start to talk more, they realize they have more in common than they thought. A slow - burning attraction develops, and finally, they share a kiss that symbolizes a new beginning for both of them, away from the dark pasts of their families.
In a Draco and Astoria marriage fanfiction, it could focus on how they handle family secrets. Draco has many secrets from his past as a Death Eater in training. Astoria discovers some of these secrets accidentally. She is shocked at first but decides to help Draco face his demons. They go on a journey together, visiting places from Draco's past, like the Malfoy Manor. Through this process, their marriage becomes stronger as they learn to trust each other completely.
