Well, one possible plot could be that Death Eaters who suspect Snape of being a double agent kidnap him. They might take him to a secret lair and try to torture him for information. Snape, being as tough as he is, would hold his secrets as long as possible. Maybe Harry and his friends find out and embark on a rescue mission, having to face their former enemies to save Snape.
The Death Eaters are a likely choice. Since Snape was a double agent, some of them might have suspected his true loyalties all along. Once they got the chance, they would kidnap him to either punish him or to get information out of him about the Order of the Phoenix.
One great fanfiction could be 'The Unlikely Bond'. In this fic, Hermione discovers Snape's past through a series of magical encounters. Another is 'Snape's Hidden Side', where Hermione stumbles upon a secret project of Snape's that makes her see him in a new light. There's also 'Hermione and Snape's Shared Secrets' which delves into how they gradually start to trust each other.

In the fanfiction realm, their relationship development is often complex. Sometimes it begins with a magical accident that links their minds briefly.

As the story unfolds, they might find themselves in situations where they have to rely on each other, like during a dark wizard attack on Hogwarts. This mutual reliance and the growing understanding between them transform their relationship from one of animosity to a more positive one.
In some fanfictions, Snape has badass moments when he outsmarts Voldemort. For example, he manages to mislead Voldemort about the location of a crucial magical artifact. He uses his Occlumency skills to his advantage, hiding his true thoughts and intentions while presenting false information in a very clever way. This not only shows his intelligence but also his courage as he risks his life to deceive the Dark Lord.
Well, Harry Potter would likely still be a main character. His relationship with Snape could be even more complex in this fanfiction. Since Snape is a demigod, Harry might be both in awe and a bit scared of him at times.
At the start, Snape would likely be quite suspicious of Naruto. He's used to a world full of secrets and might think Naruto is some sort of threat or spy. Naruto, being Naruto, would keep trying to break through Snape's cold exterior. He might start by complimenting Snape's skills in potions or magic. As time goes on, Snape might see Naruto's good heart and start to open up a bit more. They could end up having some interesting conversations about power, loyalty, and friendship. Naruto could tell Snape about his bonds with his friends in the ninja world, and Snape could share some of his own experiences with the Marauders from his school days.
In these fanfictions, Snape often becomes more self - reflective. He starts to realize the full extent of his actions and how they've affected others.
