Ask a short story about Snape, there is a Deha plot, and it seems that there is a Snape in the ending who destroyed Harry because of jealousy.

There are many classic works that can be used to refer to Professor Snape's articles in the Harry Potter novels: - Harry Potter and the Deathly Hallows: Professor Snape is one of Hogwarts 'professors and a loyal follower of Lord Voldemort. He sacrificed himself to protect Lily Potter and Harry Potter, but his story is also full of unforgettable emotions and philosophical considerations. - Harry Potter and the Half-Blood Prince: In this novel, the image of Professor Snape becomes more complicated and profound.

After Voldemort's resurrection, he became one of Harry and Dumbledore's main enemies. His story was even more shocking, revealing the darkness and pain in his heart.

One popular Snape - Harry fanfic with the concept of Snape knots could be 'The Unraveling of Snape's Knots'. In this fic, it might explore the complex relationship between Snape and Harry through the metaphor of knots, perhaps representing the tangled emotions and secrets between them.

The story might focus on their unrequited love, the conflicts between them, or how their paths crossed in unexpected ways. It could also explore the impact of their connection on the larger wizarding world.

In some fanfictions, Snape's care for Harry might be shown through secret protection. For example, he might keep an eye on Harry during dangerous situations at Hogwarts without Harry knowing. He could also subtly guide Harry in his studies of Potions, giving him hints that are not obvious to others.

One possible reason in fanfiction could be that Snape's constant bullying and unfair treatment finally pushed Harry over the edge. Harry might have felt that he couldn't take it anymore, especially if Snape made his life at Hogwarts unbearable in ways that the other teachers didn't notice or couldn't stop.

Yes, 'The Knots That Bind and Heal' is a great one. In this fanfic, the Snape knots initially represent the misunderstandings and animosity between Snape and Harry. But as the story progresses, they start to untangle. By the end, Harry and Snape come to a mutual understanding and respect for each other, which is really heartwarming.

A common plot device is misdirection. Harry might create a false lead or distraction that makes Snape focus on the wrong thing. For example, he could stage a minor 'accident' in the corridor that draws Snape's attention while he slips away to do something else he's not supposed to. Another device is using his friends' unique abilities. If Hermione has found a loophole in a rule, Harry can use that knowledge to outmaneuver Snape who is always strict about the rules.

One great fanfiction could be where Harry finally masters Occlumency under Snape's begrudging but effective teaching. Snape, with his deep knowledge of the mind arts, forces Harry to confront his innermost fears and traumas. Harry, in turn, starts to understand Snape better, realizing that his harshness is a facade for a more complex and damaged personality. This could lead to a more nuanced relationship between them, with Harry growing in power and self - awareness.

In some fanfictions, there could be other dark wizards or witches who are allied with Voldemort or have their own reasons for wanting to harm Harry. Snape would have to protect Harry from these various threats as well. For example, some Death Eaters might try to take matters into their own hands and go after Harry without Voldemort's direct orders.

Dumbledore could be involved. He often has his fingers in many pies at Hogwarts, so he might be the one who arranges for Snape to deliver the letter to Harry for some greater good or part of his grand plan. Another possible character could be Hermione. She might notice something strange about Snape delivering the letter and start to investigate, suspecting that there's more to it than meets the eye.
