In this kind of fanfiction, a possible plot is that Hermione gets involved in a magical mishap that damages Snape's classroom. As a punishment, Snape forces her to stay after class every day for a month to help him organize his potion ingredients. Another situation could be that Hermione challenges Snape's teaching methods in front of the class. Snape then gives her the task of teaching a potions class herself under his strict supervision as a form of punishment. Also, if Hermione is caught using a spell without permission in Snape's class, he might punish her by making her copy out a long list of complex potion - making rules a hundred times.
One plot idea could be that Snape takes Hermione under his wing after he discovers her extraordinary magical potential at a young age. He secretly trains her in advanced potions and dark arts defense, much to the surprise of the other Hogwarts faculty. Another could be that Hermione's parents die unexpectedly, and Snape, having a soft spot for her intelligence, steps in as a guardian. He helps her navigate the complex wizarding world politics while she tries to uphold her muggle - born values.
One plot idea could be that during detention, Snape discovers Hermione's hidden talent for potion-making that even he hadn't expected. He starts to see her in a new light, not just as an over - achieving Gryffindor. Another idea is that they get trapped in the detention room due to a spell gone wrong, and they have to work together to get out, which leads to a grudging respect between them. And perhaps Hermione finds an old diary in the detention room that has some secrets about Snape's past, which she uses to understand him better.
Another plot could be that Hermione gets transported back in time and ends up as a student when Snape was still at school. She sees a different side of him, not just the strict professor she knew. They might team up to deal with some dark magic threats in the school at that time. Snape could initially be suspicious of her but then realize she has valuable knowledge from the future.
A possible plot is that she has a special gift for potion - making, like Snape, but also a love for books and knowledge like Hermione. This leads her to create new potions based on old, forgotten spells she discovers in the library. However, there are those who are jealous of her abilities and try to stop her progress.
A third plot idea is that Hermione accidentally stumbles upon a spell that links her mind with Snape's. Through this connection, she experiences his memories and emotions. This allows her to see his side of the story, especially his unrequited love for her mother - like figure, Lily. As she delves deeper into his mind, she starts to change her view of him completely and tries to help him find some peace in his tortured existence.
Well, a plot could be that there is a mystery in Hogwarts that only Snape and Hermione seem to notice. They start investigating together, initially distrusting each other. As they dig deeper, they find that it is related to a long - forgotten potion recipe. Along the way, they have to face challenges like avoiding other teachers' suspicions and dealing with some magical creatures that are guarding parts of the mystery. Another interesting plot could be that Snape and Hermione are magically linked in some way, perhaps due to a spell gone wrong. They start experiencing each other's emotions and memories, which forces them to understand each other on a much deeper level. This could lead to a whole new relationship between them, different from the typical student - teacher dynamic.
One idea could be that Snape discovers Hermione has a rare magical ability that he's secretly been researching. He takes her on as an apprentice of sorts, much to the surprise of everyone. This could lead to a series of adventures where they explore the depths of this magic together and Snape slowly starts to see Hermione in a new light.
One plot idea could be Snape having to protect Hermione from a dark magic threat that is targeting her specifically. Maybe he initially resists the idea but gradually realizes her importance. Another could be a time - travel plot where Hermione goes back in time and has to work with a younger, even darker Snape to change some crucial events in the wizarding world. And a third idea might be that Snape and Hermione are forced to team up in a dangerous underground magical tournament where they have to rely on each other's skills to survive.
One idea could be a story where Hermione, through some magical accident, is transported back in time and has to work with a younger Snape and Bill. Maybe they are on a mission to save Hogwarts from a dark wizard before Voldemort's rise. Hermione's modern knowledge of magic combined with Snape's potions expertise and Bill's adventurous spirit could lead to an exciting adventure.
One idea could be a time - travel plot where Hermione goes back in time and has to work with a younger Severus Snape. They could team up to prevent a dark wizard from rising earlier than in the original timeline. This would put them in a situation where they have to trust each other despite their differences in age and temperament.
