It could imply an eternal or unending love story. It might suggest that the love in the story is continuous and never - ending, always present and always evolving.
Harry Potter could visit Snape in the hospital. Despite their past differences, Harry might feel a sense of obligation or curiosity. He could be there to finally have an honest conversation with Snape and perhaps gain a better understanding of his actions throughout the years.
Snape might initially be shocked. He's not one to show much emotion openly, but internally he could be very disturbed. He might start investigating what happened to Hermione immediately, using his skills in potions and magic to try and find a cure or at least understand the cause.
Snape could initially be skeptical. Given their long - standing enmity, he might not believe that Harry's apology is sincere at first. He might respond with a cold glare or a sarcastic comment, like 'Potter, your apologies are as empty as your head.'
To evaluate Snape's characterization, look at how his loyalty is portrayed. In the original series, he was loyal to Dumbledore but also had a complex past with Voldemort. His relationship with students, especially those in Slytherin, should also be considered. If he's too soft or too harsh compared to the books, it might be a sign of poor characterization.
There could be other Death Eaters that Snape knew in his life. In the afterlife, they might be there to either confront him about his double - agent status or to seek redemption themselves. And sometimes, characters from Snape's childhood, like his parents or childhood friends, might appear to add more depth to his backstory and his experiences in the afterlife.
Snape might initially be taken aback. He's used to students being intimidated by him, so Hermione's outburst could shock him into momentary silence. Then he might retaliate with his usual sarcasm, trying to put her in her place.
This could be a modern AU (Alternate Universe) fanfiction where the magical setting is replaced with a contemporary one and Snape takes on a non-magical job like being a bartender.
A real - life example could be the story of Queen Victoria and Prince Albert. Their love was a constant in their lives. They supported each other, and their relationship was based on a deep and abiding love. Their love was always present in the decisions they made together, in the family they raised, and in the way they influenced each other's lives. It was a love that was always there, through good times and bad, much like what an 'always always love story' might describe.
