The Veela in this fanfiction could have a unique connection to Snape's past. Maybe she knew his mother or was somehow involved in his family's history. For Harry, she could represent a new form of magic that he has to learn to deal with. The fanfiction could explore how Snape's relationship with the Veela affects his relationship with Harry. For example, if the Veela shows an interest in Harry, Snape might become more protective of him out of a sense of duty or a hidden affection for the Veela herself.
One possible scenario in such a fanfiction could be that a Veela's charm affects Harry Potter and Severus Snape in different ways. Harry, being young and more impressionable, might initially be more overtaken by the Veela's allure. However, Snape, with his more guarded nature, resists it at first. But as the story progresses, the Veela's magic could start to break down Snape's defenses in unexpected ways. Maybe the Veela has a task or a prophecy related to them, and both Harry and Snape are drawn into this mystery together.
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.
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.
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.
There are many fanfictions that explore Severus Snape's father. Some might depict him as a cruel man who had a negative impact on Snape's childhood. In some fanfictions, he could be an absent figure, which might have contributed to Snape's rather solitary and often bitter nature.
One possible fanfiction could be about Severus Snape discovering a new magical creature on the Hogwarts grounds and Harry Potter getting involved. Maybe it's a creature that has the power to heal dark magic wounds, and Snape initially wants to keep it a secret for his own reasons, but Harry stumbles upon it. They then have to work together to protect the creature from those who might want to use it for evil.
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.
It's not overly popular. Most of the mainstream fanfiction tends to focus on pairings that were either hinted at in the original books or that follow a more traditional romantic storyline. Harry and Snape have a complex relationship in the original series that is more of a mentor - student - turned - uneasy - allies thing. So the idea of them getting married is quite out - there for a lot of fans.
There's a fanfiction titled 'Snape's Hidden Guidance'. In it, Snape realizes early on the importance of Harry and decides to mentor him in potions and also in understanding the darker side of magic. This fic delves deep into Snape's character, showing his complex motives. He's not just mentoring Harry to help him, but also to fulfill some of his own unspoken desires related to Lily. It's a really engaging read.
One great fanfiction is 'The Prince's Tale Reimagined'. It delves deeper into Snape's relationship with Harry from Snape's perspective. Another good one is 'Snape's Redemption Arc'. It shows how Snape's actions throughout the series can be seen in a different light, with a focus on his complex relationship with Harry. And 'A Different Kind of Magic' is also a wonderful read. It creates an alternate universe where Snape and Harry have to work together more closely from an earlier point in the story.
One appeal is the novelty. It's not something you'd expect in the normal Harry Potter world, so it grabs attention. Fans like to see familiar characters in new and unexpected situations.
