One possible reason could be a moment of intense emotion. Maybe Draco is frustrated with Hermione's success or her constant opposition to his ideas in the wizarding world. It could also be a misinterpretation of feelings. For example, he might actually have some hidden admiration for her but doesn't know how to express it in a positive way, so it comes out as this aggressive action. Another aspect could be related to the overarching plot of the fanfiction world. Perhaps there's a power struggle or a mystery that involves both of them, and this physical act is a turning point in the story.
It could be due to a magical influence. Maybe there's a spell or a dark magic object that affects Draco's behavior towards Hermione. In the wizarding world, there are many things that can manipulate one's actions. This incident could then lead to a series of events where they have to work together to find a solution. For example, they might need to find a counter - spell or figure out who is behind this magical interference. It also could be that Draco is being blackmailed into doing this as part of a larger, more complex plot in the fanfiction.
Hermione could also be more understanding in some fanfictions. If she senses that there's something deeper behind Draco's actions, she might try to calm the situation down. She could ask him why he did it instead of immediately retaliating. Maybe she sees a glimmer of vulnerability in his eyes and decides to approach the situation in a more empathetic way. This could then lead to a conversation that changes their relationship for the better.
One possible plot could be that they are in a dangerous situation together. Maybe they are facing a dark wizard attack and have to take cover against the wall. They could be using their combined magical skills to fend off the attacker. For example, Hermione might be using her quick - thinking and vast knowledge of spells, while Bill with his experience as a curse - breaker could be using his more practical combat magic.
Perhaps the kiss is a moment of impulse for Draco, who has been secretly attracted to Hermione's intelligence and courage all along. Hermione, on the other hand, is initially shocked but then realizes she has some feelings for Draco too. Their relationship could then develop as they try to find common ground between their different houses' values. They might start working together on a project in the library, away from the prying eyes of their classmates, and slowly build a deeper connection through their shared love for learning and magic.
Well, perhaps it's part of a rescue mission gone wrong. She's pushed up against the porthole while trying to escape from some dark wizards. Her friends are nearby but are preoccupied with fending off other threats. She might be using the porthole as a vantage point to look for an escape route or a way to signal for help.
Another reason could be related to a spell or a magical effect. There might be a love - inducing spell or some kind of magic that made Draco act in this way towards Hermione. The neck kiss could be the first physical manifestation of this magically influenced attraction.
I'm not entirely sure as 'lemon' in fanfiction often implies mature or inappropriate content which I don't promote. But generally, if it were a proper, non - adult story, it could be about Hermione in a tense or confrontational situation against a wall, perhaps in a magical duel or an intense argument within the world of the Harry Potter universe.
Maybe it's because of their different outlooks on life in the wizarding world. Hermione is very much about following the rules and using magic for good and knowledge, while Draco has been more influenced by the power - hungry and sometimes underhanded ways of his family. This could lead to constant arguments and ultimately a break - up.
One possible reason could be their different backgrounds. Draco is from a pure - blood wizarding family with traditional values, while Hermione is a Muggle - born witch. Their families might not fully accept each other, leading to constant stress and ultimately divorce in the fanfiction. Another reason could be differences in their career goals. Maybe Draco wants to focus on maintaining his family's status in the wizarding world, while Hermione is more interested in promoting Muggle - wizard relations and her own academic pursuits, causing a rift between them.
In some fanfictions, it could be that Hermione starts to question and challenge long - held Gryffindor traditions. Gryffindors are often seen as brave and a bit reckless, while Hermione is more rational. Her attempts to bring in more caution or different ways of thinking might be seen as going against the Gryffindor spirit by some of her housemates. Also, if there's a power struggle within the Gryffindor house, Hermione's intelligence and influence could be seen as a threat by those who want to be in control.
It could be a friendship - based relationship. They find themselves in a situation where they are against the wall, and in that moment, they bond over shared interests or experiences. For instance, they might both be fans of a particular magical author, and as they are waiting for the danger to pass or the situation to resolve, they start chatting about their favorite books by that author, strengthening their friendship.
