In some fanfictions, Harry might come to understand Snape better and they could develop a grudging respect for each other. Harry realizes all that Snape sacrificed in the war and how he was on the good side all along.
In certain fanfictions, Harry could be the one to reach out to Snape. He might feel a sense of indebtedness towards Snape for his sacrifices. Snape, initially resistant, could eventually warm up to Harry's attempts at reconciliation. This could lead to a very different dynamic from their pre - war relationship, with them learning from each other and forging a new path in the post - war wizarding world.
They could become very close friends. After the war, they both have a shared understanding of the trauma and changes they've been through. They might support each other in rebuilding their lives at Hogwarts or in the wizarding world in general.
In some fanfictions, they might become closer friends than ever. After the war, they've shared so much trauma and victory that their bond deepens into a platonic relationship where they support each other through post - war rebuilding and dealing with their respective emotional scars.
In some fanfictions, Snape might be seen as a mentor figure to Hermione after the war. Since he sacrificed so much and she respects knowledge, he could guide her further in advanced potions or dark arts defense knowledge.
At first, it's likely to be tense. Harry has years of seeing Snape as a bully. But as they start living together, they begin to understand each other. Snape might show his more vulnerable side to Harry, like his memories of Harry's mother. Harry, in turn, starts to respect Snape's knowledge and sacrifice. Eventually, they develop a bond like a father - son relationship.
There are also fanfictions where Harry and Fleur have a more complex relationship. Harry might develop a sort of mentorship towards Fleur's future children, given his own experiences. Fleur, in turn, could be a source of comfort for Harry during his post - war struggles with PTSD. Their relationship could be one of mutual support and understanding, evolving over time as they both move on from the traumas of the war.
In some fanfictions, they might become friends. After the war, they could realize that the old rivalries were pointless. Harry, being the forgiving person he is, might reach out to Pansy, and she, having seen the error of her ways, could accept his friendship. They could then work together to rebuild the wizarding world.
In some fanfictions, they might become very close friends. After the war, they both have endured a great deal. Harry could rely on Tonks' experience and her unique perspective. Tonks, on the other hand, might see Harry as a symbol of hope and a comrade who has fought bravely. They could support each other in rebuilding the wizarding world, sharing their stories and helping those who were affected by the war.
Some fanfictions might depict them as having a more adventurous post - war life. They could be involved in rebuilding the wizarding world in a more hands - on way. Harry might use his fame and Ginny her popularity among the younger wizards to bring about positive changes. Their relationship would be based on mutual respect and a shared goal of making the wizarding world a better place.
After the war, Harry and Ginny's relationship in fanfiction could be centered around family. They might start thinking about having their own family soon. Ginny would want to create a warm and loving home environment, different from the often cold and lonely upbringing Harry had. Harry, on the other hand, would be eager to be part of a real family. They would also be surrounded by their friends, like Ron and Hermione, and together they would form a tight - knit community in the wizarding world.
