One idea could be exploring Snape's early days at Hogwarts as a student. Maybe his first encounter with Lily Evans and how that shaped his future. Another could be a what - if scenario where Snape decides to fully side with Voldemort in a different way, changing the course of the wizarding war. Or perhaps a story about Snape's relationship with his fellow Death Eaters and how he really felt about them.
Well, a plot could revolve around Snape's time as a double agent. What if there was a moment when he almost got caught by Voldemort? It could show his inner turmoil and his quick thinking to save himself and continue his mission. Also, a story about Snape's relationship with his potions students, especially those who showed a special interest in the Dark Arts. This could add a new dimension to his character.
You could also set the fanfiction in a different time period or location. Transport the characters to a new setting where they experience a moment of bliss in a completely different context. For instance, if the original is set in a modern city, move it to a historical or fantasy - like place and see how the characters adapt and find their bliss there.
Well, Hermione Granger could be an interesting character to pair with Snape. Her intelligence and thirst for knowledge could clash or complement Snape's own knowledge of magic. Sirius Black could also be a good addition. There was always a sense of animosity between them in the original story, and exploring that in a different way in the fanfiction could be great. And then there's Narcissa Malfoy. Given Snape's position among the Death Eaters, their relationship could be explored in depth.
Another plot could be that Snape assigns the student to clean his office during detention. While cleaning, the student finds old parchments and journals that give insights into Snape's past, especially his time as a student at Hogwarts. The student becomes more empathetic towards Snape after learning about his difficult past and tries to befriend him, which Snape initially resists but gradually warms up to.
One idea could be exploring Snape's childhood before Hogwarts. Maybe he had a secret friendship with a Muggle that no one knew about. This could add depth to his character and explain some of his later actions.
Another interesting plot could be a backstory about how Snape first got involved with Voldemort. Maybe it was out of a thirst for power initially, but then his views changed over time. This could be delved into in great detail, showing his transformation from a potential dark wizard follower to a hero in the fight against Voldemort.
Well, it could start with Harry having to take private lessons from Snape for some special magic he needs to learn. During these lessons, they begin to understand each other's past traumas and find common ground. Maybe there's a magical bond that forms between them accidentally, like a soul - bond, which makes them feel each other's emotions. This could lead to a slow - burning relationship as they figure out how to deal with this new connection. And also, a plot where they are both on a quest to find a lost magical artifact and in the process, their relationship evolves from animosity to love.
One plot idea could be Severus Snape taking in an orphaned student from Hogwarts and becoming a father figure to them. He could teach the child not only magic but also important life lessons. Another idea is a time - travel plot where an adult character goes back in time and Severus Snape ends up being like a father to them in their new timeline.
Another plot could be that Hermione gets transported back in time and ends up as a student when Snape was still at school. She sees a different side of him, not just the strict professor she knew. They might team up to deal with some dark magic threats in the school at that time. Snape could initially be suspicious of her but then realize she has valuable knowledge from the future.
A possible plot is that she has a special gift for potion - making, like Snape, but also a love for books and knowledge like Hermione. This leads her to create new potions based on old, forgotten spells she discovers in the library. However, there are those who are jealous of her abilities and try to stop her progress.
Well, we could have a fanfiction where Snape is alone after the war. He's left to pick up the pieces of his life. He decides to go on a journey to find a place where he can truly be at peace. Along the way, he meets some muggles who unknowingly teach him about the simplicity of life. This makes him realize that he doesn't need all the magical trappings to be happy.
