A lot of fanfictions focus on the idea that Harry taking Hermione to the Yule Ball is a way for them to escape the expectations others have of them. At the ball, they find themselves in a world of their own. They could be dancing and suddenly realize that they have a unique connection that they've been overlooking. It might also involve them facing some sort of magical challenge during the ball that tests their relationship.
One great fanfiction could be where they go to the Yule Ball and it's a chance for them to really see each other in a new light. Maybe they share a slow dance and have deep conversations that make them realize their feelings for each other are more than just friendship. They might face some jealous glances from others, especially Ron who has his own complicated feelings about Hermione.
One idea could be that they go to the Yule Ball and have a magical dance, but then face some jealousy from Ron. Another could be that during the ball, they discover a secret about the tournament that is related to the Yule Ball's origin. Maybe they also have a deep conversation on the balcony about their future and how their friendship might change.
I think it would be really romantic if during the Yule Ball, when the music slows down, Harry takes Hermione's hand and leads her to a more secluded corner of the hall. There, under the twinkling lights and away from the crowd, he tells her how much she means to him. Not just as a friend, but as someone he has deeper feelings for. Hermione blushes and they share a tender moment that makes the Yule Ball truly special for them.
Harry could comfort Hermione by giving her a small gift at the Yule Ball. It could be something he made himself, like a simple charmed flower that never wilts. This would show Hermione that he values her and wants to make her feel special. She would be touched by this gesture and it would help her forget about any negative feelings she had.
Their relationship could develop through shared experiences at the Yule Ball. For example, they might have a really deep conversation while dancing that makes them see each other in a new light.
One interesting plot could be that Harry is initially nervous about asking Daphne to the Yule Ball. But when he finally does, Daphne surprises him with her enthusiasm. They then spend the ball dancing and having deep conversations, which makes them realize they have more in common than they thought.
In many fanfictions, Harry might comfort Hermione at the Yule Ball in different ways. For example, he could notice her distress over Ron's behavior and simply offer a kind word or a warm smile. He might say something like 'Hermione, you look beautiful tonight, don't let Ron's stupidity get to you.' This simple act of kindness can mean a great deal to Hermione, who is often overlooked or criticized for being different.
There's also a possibility that it's a new character created specifically for this fanfiction. This new character could bring a fresh perspective and allow the author to explore different aspects of Harry's gentlemanly behavior at the Yule Ball.
Well, in fanfic, Hermione rejecting Harry at the Yule Ball could also be a way to show Hermione's independence. She's a strong - willed character. She might not want to go to the ball with Harry just because he's her friend. She could be waiting for someone who truly understands her on a deeper level, or she may simply not be in the mood for a romantic relationship with him at all.
One consequence could be a strain on their friendship. Harry might feel embarrassed or hurt, which could lead to some distance between them. For example, he might avoid Hermione for a while.
