Perhaps Hermione discovers something about Snape's past that makes her see him in a new light. She starts to be more sympathetic towards him, and this change in her attitude towards him catches his attention. Their relationship could then develop from there, with Snape gradually realizing his feelings for her are more than just respect for her academic abilities.
There could be a plot where they are forced to work together on a project. Snape initially resents it, but as they collaborate, he sees Hermione's determination and begins to fall for her. However, he has to deal with the fact that she is a Gryffindor and he has his own reputation to uphold. This creates a lot of drama and tension in the story.
One possible scenario in this fanfiction could be that Snape starts to notice Hermione's intelligence in a new way. He might see her constantly out - performing her peers in Potions class, which was his area of expertise. As he observes her more closely, he begins to admire her tenacity and thirst for knowledge. This newfound admiration could gradually turn into something more like affection.
One way it could happen is if Hermione discovers a time - turning device in the Marauders' era. She might use her advanced knowledge to figure out that Snape is in danger. For example, she could know about some plot by the Marauders to prank Snape in a way that could turn deadly. She then steps in, using her magic skills and intelligence to prevent the harm. Maybe she creates a diversion or uses a protection spell to shield Snape.
Well, in such a fanfic, it would be a really strange and interesting combination. Snape is a complex and brooding character, while Hermione is intelligent and determined. Their relationship could start with a lot of tension. Maybe the marriage law forces them together, and at first, they can't stand each other. But as time goes on, they might start to see the good in one another. Snape could be impressed by Hermione's thirst for knowledge, and Hermione could understand Snape's past traumas that made him the way he is.
If Snape goes missing, Hogwarts would be in chaos. His students would be worried and confused. The other teachers would have to take over his classes, but no one could replace his unique teaching style.
One possibility is that Naruto gets transported to the world of Harry Potter where he meets Snape. Naruto's energetic and positive attitude could clash with Snape's brooding nature. However, they might find common ground in their loyalty to their respective friends and causes. Naruto could show Snape the value of perseverance in a different light, and Snape could introduce Naruto to the complex world of potions and magic.
He could have a magical mishap. For example, a spell meant for the decorations goes wrong and lands on him, making him do something silly like dance uncontrollably. It would be a humorous take on his usually serious character.
Maybe in a time - travel fanfiction. Hermione travels back in time and ends up in Snape's student days. She tries to change some events for the better, and in the process, she gets to know a younger Snape. Their interactions are initially rocky but gradually turn into something more, leading to a kiss. This would be a very different take on their relationship, as it involves a different time period and different versions of themselves.
Magic could play a role. There could be a magical spell or potion that was involved in Hermione's conception that links her to Snape. For example, a potion that alters memories and relationships. This would make for a very interesting and complex backstory in the fanfiction. Snape might not even be aware that he is Hermione's father at first, and when he discovers it, his whole view of her would change. He would have to deal with his feelings of protectiveness and his past actions towards her in Hogwarts.
Well, one possibility is that they could have an intense conversation. Maybe Hermione discovers a side of Snape she never knew. For example, Snape could reveal some of his past traumas or secrets that make Hermione see him in a new light. It could be a moment of mutual understanding between two characters who didn't get along well in the original story.
Well, Snape could force Hermione to participate in a wizarding duel against her will. In fanfiction, this could be a way for Snape to test her skills or perhaps punish her for something he believes she has done wrong. Hermione would be in a tough situation as she is a rule - abiding student, but being forced into a duel would make her have to think on her feet and use her magic in new and unexpected ways.
