It's very rare and out of the ordinary. The typical dynamics and character traits in the official storyline make this kiss scenario in the fanfiction quite a shock and a stretch of imagination.
This plot is highly unconventional. In the Harry Potter series, there's no such indication or possibility of Snape and Hermione having a romantic connection. So, this fanfiction takes a bold and unexpected creative turn.
Yes, there are some. However, this pairing is quite controversial among 'Harry Potter' fans as it goes against the canon relationships in the original series. Some fanfictions might explore an alternate universe where such an unexpected relationship could develop, often with creative plot twists and character developments.
One possible plot could be a time - travel scenario. Hermione travels back in time and ends up in Snape's student days. They initially clash but gradually develop an understanding, which culminates in a kiss. Another could be a situation where they are both working on a dangerous magical experiment and in a moment of high tension and shared vulnerability, Snape kisses Hermione.
One way it could be justified is through a magical bond or prophecy. Maybe there's a hidden prophecy that states their union is necessary for the greater good. For example, it could be related to the balance of magic in the wizarding world.
A possible plot twist could be that Tom Riddle actually becomes a mentor - like figure to Severus Snape in a fanfiction. Riddle, seeing Snape's talent for the Dark Arts, decides to guide him in a different way than the Death Eaters would. This would completely change the way we view their potential relationship.
Fanfictions with sexual content are not suitable for discussion. Instead, we could consider fanfictions that revolve around Hermione's adventures within the Order. For example, her role in strategizing against the dark forces, or how she uses her intelligence to solve various problems faced by the Order.
One possible plot could be that Hermione is struggling with the pressures of her studies and the ongoing battle against the Dark Arts. Snape, being a complex character, might notice her distress in his own way. Maybe he initially dismisses it but then realizes she's in a deeper state of depression. He could then use his knowledge of potions to try and help her, leading to an unexpected bond between them.
One possible plot could be that Snape discovers Hermione has been sneaking into the restricted section of the library for some research that could get her in big trouble. He threatens to expose her to the school authorities unless she does his bidding, like helping him with some dangerous potions experiments. This would put Hermione in a difficult situation as she doesn't want to break the rules further but also doesn't want to get in trouble.
A great plot twist could be that younger Snape actually has some knowledge of Hermione's time - traveling. Maybe he's been having strange dreams about the future and when he meets Hermione, he realizes she's part of it. This would completely change the power dynamic between them.
Well, it could start with a medical emergency for Hermione that brings her to Snape's doorstep. From there, their interactions could reveal hidden aspects of their characters and build a complex relationship. Maybe there's a mystery illness or a series of challenging cases that they have to solve together.
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.
