A great fanfic could involve Harry being bullied by some Slytherins and Snape steps in. He takes Harry to his office and instead of scolding him, he offers him a cup of tea. Snape then tells Harry about how he himself had to deal with difficult situations at Hogwarts when he was young. By opening up like this, Snape comforts Harry and makes him realize that everyone has their own battles. Harry leaves the office feeling more confident and less alone.
There's a fanfic where Harry is feeling guilty about Sirius' death. Snape comes across Harry in the Astronomy Tower. At first, Harry is defensive, but Snape just stands there quietly. Then he starts to talk about how loss is a part of life, and how he has lost many people too. He doesn't offer false sympathy but rather a cold, hard truth that somehow makes Harry feel better. Snape's no - nonsense approach in this fanfic gives Harry the strength to move forward.
One great example could be a fanfic where Harry is distraught after a difficult encounter with a Dementor. Remus, using his calm and understanding nature, sits Harry down and shares his own experiences with the dark creatures. He tells Harry how he overcame his fears and how Harry can do the same. This helps Harry gain confidence and feel less alone in his struggles.
One great example could be 'A Different Sort of Guidance'. In this fanfic, Snape takes Harry under his wing in a more private and reluctant way. He starts to teach Harry about advanced potions and also imparts some of his knowledge about the Dark Arts, not to encourage Harry to use them, but to understand the enemy better. Another is 'Snape's Unlikely Apprentice', where Snape is forced to mentor Harry due to a magical decree, and their relationship develops from one of mutual dislike to grudging respect.
The relationship can be developed by having Snape protect Harry in unexpected ways. Maybe in a fanfic, there's a plot where some dark wizards are after Harry. Snape, secretly, uses his skills to keep Harry safe. Later, when Harry discovers this, Snape has to explain his actions. This explanation can be a turning point where they start to trust each other more. Snape can then start to offer words of comfort based on his understanding of Harry's situation. They could also start to work together on some small tasks, like researching a new potion that might help Harry in his fight against the dark side, which further cements their relationship.
In some fanfictions, Fleur might comfort Harry when he is mourning the loss of a loved one. She could use her Veela charm in a gentle way, not to seduce but to soothe. For instance, she could make a special potion or cook a French dish that she learned from her family to cheer Harry up. The story might focus on the cultural exchange between them as well as the emotional support Fleur provides.
Another scenario might be that Hermione has a fight with her friends. Draco, who has grown to understand her better, takes her for a walk in the Hogwarts grounds. He tells her that friendships have their ups and downs. He shares stories of his own rocky relationships with his Slytherin mates, making her feel less alone.
One great 'ginny comforts harry fanfic' could be 'A Shoulder to Lean On'. In this fic, Ginny finds Harry at a really low point after a difficult battle. She uses her warm and understanding nature to comfort him, reminding him of his strength and the love they share. It has some really heart - touching moments.
The theme of forgiveness also often appears. Harry, having known Snape's past actions that were not always in his favor, has to come to terms with forgiving Snape in order to accept his comfort. And Snape, in turn, has to forgive himself for his past misdeeds. Another theme could be the power of connection. Despite their differences, they find a connection through shared pain or a common goal, and this connection is what allows Snape to comfort Harry.
Another way Snape could comfort Harry is by standing up for him in certain situations. Maybe when other teachers or students are being unfair to Harry, Snape steps in and defends him. This act of protection can be a great source of comfort for Harry, as it shows that someone is on his side even if they have had a rocky relationship in the past.
In certain fanfic scenarios, Snape may feminize Harry by influencing his appearance. Maybe he gives advice on clothing or grooming in a way that makes Harry seem more feminine. For instance, suggesting a more delicate style of robes or a different hairstyle that is associated with femininity in the wizarding world.
One example could be a fanfic where Draco finds Hermione in the library during a thunderstorm. She's clearly scared, and Draco, instead of his usual snide self, sits beside her and starts a conversation about books to distract her. He might share some of his own fears related to storms from his childhood, making Hermione feel less alone.
