Hermione could accept out of curiosity. She's always been interested in knowledge and understanding people. This would be a unique opportunity to get to know Snape on a different level. Maybe she hopes to learn more about his past, his knowledge of the Dark Arts, or his reasons for being so harsh in class. It would be a chance for her to see if there's more to him than meets the eye.
She might decline. Hermione is a very practical and goal - oriented person. She has her studies and her friends to think about. Going on a date with Snape, who has a rather complex and not - always - friendly reputation, might seem too risky and not in line with her plans. Also, she may not have any romantic feelings for him at all.
Hermione might initially be very suspicious. Given her intelligence and wariness, she would not easily fall for the temptation. She would likely question Snape's motives and try to analyze the situation from all angles.
One possibility is that Hermione would be extremely shocked. She might initially think it's some sort of joke or a test. Given their previous relationship in the original story, where Snape was often strict and not exactly friendly towards her, this sudden change would be quite a surprise. She might hesitate and not give an immediate answer, needing time to process this unexpected turn of events.
Snape would probably be quite surprised at first. Hermione is known for her academic prowess and self - sufficiency. His reaction could range from being dismissive, thinking she should be able to solve her own problems, to being intrigued by the nature of her request. If it's something related to the dark arts or a mystery in the wizarding world, his interest might be piqued, but he'd still be guarded in his response. He might even try to use her request as a way to gain some advantage or information for himself.
He could also be a bit sarcastic in his response. Snape has a sharp tongue, so he might say something like 'Miss Granger, what makes you think I have the time or inclination to help you?' But as Hermione explains her situation, he might gradually soften, realizing the seriousness of the matter. Maybe he starts to see a bit of himself in Hermione's thirst for knowledge.
She would probably be very angry. Hermione is a strong - willed character. She might immediately try to break free from his grip and demand an explanation. For instance, she could shout at him, 'Professor Snape, what do you think you're doing? This is completely unacceptable!'
She might say yes right away. Hermione has deep feelings for Harry as a friend, and those could easily turn into romantic feelings. She would see all the good in Harry and believe that they could have a great relationship together.
The 'time - travel' trope is also quite common. For example, Hermione might go back in time and interact with a younger Snape, which can lead to all sorts of new storylines and character developments.
One great Snape and Hermione fanfiction is 'The Unbreakable Bond'. In this story, Hermione discovers a hidden side of Snape during her research in the Hogwarts library. Their relationship starts as a mentorship but gradually evolves into a deep friendship that defies the expectations of the wizarding world. It beautifully portrays their individual characters and how they can complement each other.
One possibility is that Snape initially refuses to help Hermione. He has his own grudges and is often portrayed as a cold character. But as the story progresses, he might see something in Hermione's situation that relates to his own past or values, and reluctantly start to offer some guidance.
Hermione might become more guarded at first. She is used to being independent and suddenly being 'gifted' to Snape is a big change. But over time, she could learn to be more patient and understanding. Snape, on the other hand, might soften a bit. His usual cold exterior could crack as he gets to know Hermione better.
