One plotline could be that they are victims of a prank by some mischievous students using a new, untested spell. They then have to figure out how to break free and also how to deal with the fallout of being in such an embarrassing situation together.
There are some fanfictions that might explore this scenario in a non - inappropriate way, perhaps in the context of a rescue or a magical situation gone wrong where they are immobilized but not in a sexual way. However, it can be a very niche and specific type of fanfiction to find.
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.
One possible plot could be that there is some sort of misunderstanding. Fleur believes Hermione is in danger from some dark magic or a dangerous creature and ties her to the bed to keep her safe. As the story unfolds, they realize the miscommunication and work together to solve the real issue at hand. However, this is a rather strange starting point for a plot and would need a lot of careful development to make it a believable and engaging fanfiction.
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.
Well, perhaps they are both attending a wizarding conference and there is a mix - up with the room assignments. They end up in a room with only one bed. Draco is his usual haughty self at first, but Hermione is unfazed. As they start to talk through the night, they discover they have more in common than they thought. Or, in a post - war scenario, they are both part of a rebuilding effort and are forced to stay in a temporary accommodation with one bed. This situation forces them to confront their feelings that have been simmering beneath the surface for a long time.
I'm not aware of such a specific fanfiction. Fanfiction can cover a wide range of themes and scenarios, but this one seems rather unusual and perhaps not in line with the general spirit of the original works. However, the world of fanfiction is vast, and there could potentially be something out there that I haven't come across.
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.
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 they work together to tutor a group of struggling students. Snape is initially reluctant as he doesn't think Hermione can teach his way. But Hermione's fresh approach and her ability to connect with the students on a different level start to change Snape's mind. As they work together, they develop a new teaching method that benefits all the students involved.
A plotline could be that Pansy and Hermione are in a magical duel club, and Pansy ties Hermione to the bed as a new and unorthodox dueling technique she wants to test. It could also be that they are in a different time - period or an alternate Hogwarts, and the social dynamics are such that this kind of action is more acceptable in the context of a friendly competition or a rite of passage. There could also be a plot where they are both under the influence of a truth - telling potion, and Pansy ties Hermione to the bed to make sure she doesn't run away while they have a heart - to - heart conversation.
