It could be a situation where Hermione is under the influence of a potion. The potion makes her act in ways she normally wouldn't, and she is forced to touch Snape. This could then lead to a rift between her and her friends who don't understand why she did such a thing. As she tries to figure out how to reverse the effects of the potion, she also has to deal with Snape's reaction to the whole situation.
Perhaps in a plot where there's a time - travel twist. Hermione is sent back in time and some ancient magic forces her to touch Snape as a way to set off a chain of events that will change the future of Hogwarts. It could also be that a magical artifact has some sort of hold over Hermione and compels her to touch Snape, and through this, she discovers some long - hidden secrets about Hogwarts or Snape himself.
While there might be some out - of - character and inappropriate fanfictions with this plot, it's important to note that J.K. Rowling's original works do not contain any such elements. Snape has his own story arc related to his love for Lily and his role in the wizarding war, not this kind of immoral behavior.
One possible plotline could be a time - travel or alternate - reality scenario. For example, in an alternate universe where the relationships between characters are different, Snape and Hermione could have a relationship that leads to her getting pregnant. The story could then focus on how they deal with the consequences in that different world, perhaps facing opposition from others due to their age or social differences within the wizarding community.
One possible plotline could be that Hermione is forced to work under Snape in a special project. She initially resists his strict methods but gradually comes to understand his perspective and submits to his more experienced guidance in potions or some other area of magic. For example, Snape might be in charge of a top - secret research project and Hermione, with her brilliant mind, is chosen to assist. Through their interactions, she realizes that his seemingly harsh demands are actually aimed at achieving the best results.
Maybe it's a political move within the wizarding world. The Ministry of Magic might force this marriage to unite two powerful magical forces. Harry would then have to deal with his feelings for his friends like Hermione and Ron, who would be shocked. Snape, on the other hand, would have to adjust his view of Harry from a student to a partner. They could start to find common ground in their love for Hogwarts and magic in general.
Maybe Hermione is injured while exploring some dangerous magical ruins. Snape is the only one around with the knowledge and power to heal her. As he heals her, they start to have deep conversations about magic, life, and their respective pasts, which in turn builds a connection between them.
Perhaps in a fanfiction, Snape's fists are a part of a memory. For example, Hermione discovers a memory of Snape's past where his fists were involved in a fight related to something that would later impact his relationship with her. It could be a way to explore his character's backstory and how it ties to Hermione.
One possible plotline could be that Hermione discovers a hidden side of Snape during her research in the library. This could lead to a series of conversations where Snape starts to see Hermione in a different light, not just as another student. Another could be that in a dangerous situation, Hermione and Snape are forced to work together, and through this experience, they develop a newfound respect for each other.
One possible plotline could be that through some sort of time - travel magic, Hermione goes back in time and meets Salazar. They fall in love in a very unexpected way, and then she becomes pregnant. The story could then focus on how she tries to adapt to the ancient wizarding world while being pregnant and dealing with the differences in magic and society from her own time. Another plotline might be that Salazar somehow returns to the modern day in a spirit or reincarnated form, and he and Hermione form a connection that leads to her pregnancy, and the story could explore how the wizarding community reacts to such a strange union.
A plot could be that Draco and Hermione are in a situation where they are magically bound to each other for a certain task. Hermione makes a decision that Draco thinks is foolish and nearly gets them both in trouble. So, Draco punishes her by not allowing her to use her favorite magic items for a while. This makes Hermione frustrated but also makes her realize she needs to be more careful. Another idea is that in a fan - created magical world, Draco is in charge of a group that Hermione wants to be part of. She fails an initiation test set by Draco, and his punishment is to make her serve the group without having any of the privileges for a period of time. This could create a complex relationship between them as Hermione tries to earn her way back into Draco's good graces.
One possible plotline could be that Hermione discovers a way to time - travel and goes back to Snape's childhood. She decides to raise him in a more positive environment to change his future. Maybe she teaches him about love and friendship from a young age, which alters his personality and his relationship with others at Hogwarts later on.
