This would be a great opportunity to explore their complex relationship further, as Hermione sees a different side of Snape and Snape starts to respect Hermione's intelligence more.
A common plotline is an alternate universe where Snape is not as bitter and Hermione befriends him more easily.

Also, there could be a plot where Hermione accidentally enters Snape's mind through some experimental magic and discovers his deepest secrets, which then changes their relationship.
One interesting plotline could be Hermione's struggle to adjust to living with Snape. She's used to the warm and inclusive environment of Gryffindor, and Snape's dark and brooding personality makes it a big change for her.

One possible plotline could be that Hermione stands up to Snape for constantly being unfair to Gryffindor students. Maybe she discovers some misinformation he has spread about her friends and confronts him publicly in the Great Hall, causing a stir among the students and teachers alike.
A common plotline might involve Hermione's unique magic abilities being enhanced or influenced by Snape. Since she is 'gifted' to him, he could take it upon himself to train her in more advanced magic. This could include teaching her some of his own self - created spells or guiding her in the study of dark magic defense in a way that the other professors haven't. Their relationship might become a mentor - mentee one at first, but then develop into something more complex as they grow closer through their shared magical experiences.
In some versions of this fanfiction, Hermione as Snape's familiar could be involved in uncovering some long - lost secrets about Snape's past. Her inquisitive nature would drive her to dig deeper, and their relationship would evolve as they learn more about each other.

Another plotline might involve Snape discovering Hermione's use of the Time - Turner and initially being suspicious of her motives. But as they interact more in the altered timeline, they end up forming an unlikely alliance. They could work together to uncover a long - buried secret about Hogwarts that was lost in time.
Another plotline might involve Snape surviving the war, but in a very weakened state. Hermione, being the kind - hearted and inquisitive witch she is, takes it upon herself to nurse him back to health. During this process, they start to understand each other better. Snape begins to see Hermione not just as a know - it - all Gryffindor, but as a truly brilliant witch with a deep sense of justice. Hermione, on the other hand, realizes that Snape's actions during the war were far more complex than she initially thought.

They end up in a situation where they are physically close and 'rubbing up against' each other in a strange magical way. This could force them to work together to reverse the spell, leading to character development and an unexpected bond.
