In this fanfiction, there could be a plot where Hermione is cursed and can only be around Severus for protection. Severus, not being one for sentiment, initially treats her like a pet - feeding her, keeping her in his quarters. But as time passes, he realizes her intelligence is still intact despite her situation. Hermione, on the other hand, uses this time to study Severus's potions and magic up close. Their relationship evolves from a captor - pet like dynamic to a mutual respect and friendship as they work together to break the curse.
One idea could be that Severus discovers Hermione has a unique magical ability that only he can help her control, and in the process, he starts to see her as more than just a student. Another could be that Hermione is turned into a small, magical creature by accident, and Severus takes her in as a pet to protect her until she can be turned back. And perhaps, Severus initially resents having to take care of her but gradually grows fond of her presence.
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 Hermione discovers she has a long - lost family connection to Severus. Maybe they are distantly related through some ancient magic lineage. This could lead to them having to work together to protect their family's magical secrets from dark forces.
One idea could be that Severus and Hermione have to protect their baby from dark forces. Maybe there are some old enemies of Severus who target the baby to get revenge. Another plot could be the baby having some unique magical abilities that they need to figure out how to handle and train.
Perhaps the story could focus on the child's struggle with the fact that their parents were from two very different Hogwarts houses. Hermione from Gryffindor and Severus from Slytherin. This could lead to the child having an identity crisis and trying to find their place in the wizarding community, both among their peers and in the context of the long - standing house rivalries.
Well, a plot could involve Severus using his potions expertise to ensure a healthy pregnancy for Hermione. Since they come from different backgrounds, there could be a cultural clash within the wizarding society regarding their relationship and the pregnancy. And perhaps the baby has some unique magical abilities that start to show even before it's born, which attracts the attention of both good and bad wizards.
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.
Perhaps Harry takes Severus, in his pet form, on a journey through the Forbidden Forest to find a rare magical herb that could potentially break the spell. Along the way, they encounter various magical creatures and face many challenges together. Harry starts to understand Severus better through this shared adventure, even in his pet form. For example, Severus in his pet form might show his loyalty and protect Harry from a dangerous Acromantula.
One plot idea could be Hermione discovers her Parselmouth ability during a dangerous encounter in the Forbidden Forest. She uses it to communicate with a hidden snake colony that holds the key to an ancient magic secret. Another could be that she has to hide her ability from her friends at first because of the stigma associated with Parselmouths, but then it becomes crucial in a battle against dark wizards.
A possible plot could be that Hermione is mute from a very young age. She has to work twice as hard to be noticed in the wizarding world. As she enters Hogwarts, she uses her intelligence in unique ways to make up for not being able to speak. She might create a special magical device that can 'speak' for her when she types in her thoughts. This device could also be a target for villains who don't want her to spread her knowledge.
One idea could be that Severus discovers Hermione is in danger from some dark magic users due to her intelligence and Muggle - born status. He takes it upon himself to protect her like a father would. For example, he could secretly follow her around Hogwarts, using his skills in potions and the Dark Arts to thwart any threats.
