Maybe in an alternate universe where Voldemort has been defeated much earlier. Harry and Snape are forced to work together on some post - war magical restoration project. They are both alone in a cold, old castle wing during a snowstorm. Harry, who has grown to see Snape in a different light, offers to share his warmth. Snape, surprisingly, accepts, and they end up cuddling while sharing stories of their lonely childhoods.
In a story, perhaps there is a magical accident that makes Snape lose his memory. He forgets all his grudges and animosity. Harry, being the kind - hearted person he is, takes care of Snape. As Snape recovers, he becomes more and more dependent on Harry's kindness. One evening, while sitting by the fire, Snape falls asleep leaning on Harry, and Harry just cuddles him, seeing him as a vulnerable person in need of care rather than the old, strict Potions master.
One possible plot could be that after a particularly difficult battle, Harry realizes Snape's true self and the sacrifices he made. In a moment of understanding and new - found respect, Harry approaches Snape. Snape, initially hesitant, allows Harry to get close. They start to talk about their past misunderstandings, and as the conversation deepens, Harry, out of a sense of comfort and connection, cuddles with Snape as a sign of forgiveness and new - beginning.
Hermione would probably be very shocked at first. She has always seen Snape as a rather cold and unapproachable figure. But after some thought, she might understand Harry's motives if he explained that it was about finding common ground and healing old wounds. Ron, on the other hand, would likely be more openly skeptical and might make some sarcastic comments at first, but eventually come around when he sees the positive impact it has on Harry.
Often in fanfiction, the ring can be a plot device. It could be that Harry Potter unknowingly has a connection to the ring, and Severus Snape has to keep it from falling into the wrong hands. This creates a situation where Snape has to protect both Harry and the ring, leading to some tense and interesting storylines.
A lot of fanfic writers will create unique storylines for Snape's courtship. They might introduce an original character who manages to break through Snape's tough exterior. His courtship would then involve him struggling with his own insecurities and his reputation. This character might see the good in him that others overlook. There could be moments of tension and misunderstanding, but also deep, meaningful conversations as they get to know each other better.
The plot could involve a Veela who is seeking revenge on Hogwarts for an old wrong. She targets Harry Potter as he is the famous Boy Who Lived, thinking that by getting to him she can get the attention of the wizarding world. Severus Snape, being the ever - vigilant professor, senses something is wrong. He starts to investigate and discovers the Veela's plan. As he tries to protect Harry, he also uncovers some secrets about his own past that are related to the Veela. Along the way, Harry and Snape have to put aside their differences and work together to stop the Veela's vengeful plot.
In this fanfiction, the story could start with Harry finding Snape in a very vulnerable state after the Battle of Hogwarts. Harry feels a deep sense of guilt for how Snape was treated throughout his life. So he decides to adopt him. At first, their relationship is awkward. Snape is still his old sarcastic self, but Harry is determined. As time passes, they discover they have a lot in common. They both lost their parents at a young age, and they both had to face great challenges. This newfound understanding leads to a transformation in their relationship. Harry helps Snape to come out of his shell of bitterness, and Snape teaches Harry more about the Dark Arts in a controlled and ethical way so that Harry can better protect the wizarding world in the future.
The plot could involve Snape collaring Harry as a form of punishment for some misbehavior that endangers the wizarding world. But then, as they are forced to interact more because of the collar, they start to understand each other better. For example, Harry might learn about Snape's past and his true loyalties.
In some fanfictions, Snape might share some of his knowledge about the wizarding world's secrets with Harry. Maybe he tells Harry about certain spells or magical artifacts that could help Harry in his fight against Voldemort. This act of sharing knowledge is a way of being nice as it gives Harry an advantage in his battles.
Fanfiction about Severus Snape courting Harry Potter can range from quite romantic to more of a platonic exploration of their connection. Some fics might focus on Snape's redemption arc and how his feelings for Harry develop over time. It could also be a way to rewrite the somewhat tragic and unfulfilled aspects of Snape's life in the original books. However, it also needs to be done carefully to stay true to the essence of the characters and the magical world that J.K. Rowling created.
A really unique fanfiction concept could be one where Snape and Harry time - travel. They go back to key moments in wizarding history and have to work together to fix things that went wrong. This would be an exciting adventure and would force them to rely on each other.
One idea could be that Snape takes Harry in secretly. He teaches Harry advanced potions and magic in a more personal way, away from the prying eyes of Hogwarts. Harry begins to see Snape in a new light, not as the mean professor but as a strict yet caring guardian.
