In some fanfictions, Snape might blackmail Hermione over her grades. For example, he could threaten to expose some small mistakes she made in her potions work if she doesn't do him a favor, like helping him organize his ingredients. This creates a tense situation between them and often leads to Hermione trying to outwit Snape in some clever ways.
Another plot could be Snape blackmailing Hermione about her secret study group. He might demand that she includes certain students he favors in the group or he'll report it as an unauthorized gathering. Hermione then has to figure out how to deal with this without sacrificing the integrity of her study group.
Hermione may also start to scheme. She'll use her intelligence to come up with a plan. For instance, she might start to collect evidence against Snape, something that she could use to counter his blackmail. She'll research old school rules or find out secrets about Snape that she can hold over his head instead.
One possible plot could be that Hermione is stalking Snape to uncover some long - lost potions secrets that she believes he has. Maybe she suspects he's hiding a powerful antidote formula. Another plot could involve her stalking him because she thinks he has a connection to a dark wizard from the past and she's trying to prove it to protect Hogwarts. And in some fanfictions, she might be stalking him out of pure curiosity about his personal life, which is always so mysterious in the original series.
One common plot is the 'forbidden love' aspect. Since Hermione is a Gryffindor and Snape is a Slytherin, and there's also a significant age gap and the teacher - student relationship factor in the original story. In fanfictions, they might overcome these barriers gradually. For example, they could start by having a mutual understanding of each other's intelligence. Hermione respects Snape's knowledge of potions, and Snape begins to see Hermione's potential beyond her house and age. Another plot could be a time - travel scenario where Hermione goes back in time and gets to know a younger Snape, and they develop feelings in a different context, away from the usual Hogwarts hierarchy.
One possible plot could be that Snape, in a rather devious way, tempts Hermione with the knowledge of some long - lost, powerful magic. He might dangle the opportunity to study it in front of her, knowing her thirst for knowledge. Another could be that he tempts her with a chance to change some past events in the wizarding world that she has always regretted not being able to influence. For example, he could offer her a way to prevent certain tragedies that occurred during the wizarding wars.
A possible plot is that they have to deal with the public's reaction. The wizarding community is shocked by their union. Hermione faces discrimination from some pure - bloods who think she's not worthy of Snape. Snape, who has always been an outcast himself, tries to protect Hermione from the harsh words. As they face these challenges together, they grow closer and start to develop real feelings for each other.
One interesting plot could be that Hermione discovers Snape is ill or injured in a post - war scenario. She uses her vast knowledge of magic to nurse him back to health. During this process, they start to understand each other better. Snape, who has always been a rather aloof and misunderstood character, begins to open up to Hermione, sharing his past traumas and the reasons behind his actions in the war.
One possible plot could be that Hermione breaks a major rule in Snape's potions class, like using an unapproved ingredient. Snape punishes her by making her clean all the potion vials in the classroom after hours. This gives them a chance to have some tense conversations where Hermione stands up for herself and Snape realizes she's not just a rule - breaker but a passionate learner.
Another plot could be a time - travel scenario. Queen is magically transported to the wizarding world and meets a younger Snape and Black Hermione. Queen's different style and music could inspire Black Hermione to create new kinds of magic spells that are more in tune with creativity and self - expression. Snape, on the other hand, is skeptical at first but later realizes the potential of this new form of magic.
A plot where they are forced to team up to solve a mystery within Hogwarts. It could be a mystery related to the Chamber of Secrets or some other hidden part of the castle. During this time, they have to rely on each other's strengths, and Hermione starts to see Snape as an ally rather than just a strict teacher.
Perhaps in a story where there's a spell gone wrong. The spell causes Snape and Hermione to be linked in a strange way. They start to experience each other's emotions and memories. As they work together to break the spell, they develop a deep connection and Snape, who has always been a complex character, shows a softer side and kisses Hermione as a sign of his new - found feelings.
