They could become even closer friends. After going through the war together, they have a deep bond. Maybe they start to rely on each other more than ever, sharing every little detail of their lives.
There's a possibility that their relationship could turn romantic. With Ron out of the picture (assuming in this fanfic's context), they might start to see each other in a new light. They've always had a strong connection, and the post - war peace could make them realize their feelings for each other. They could start dating, going on magical dates around the wizarding world.
In many of these fanfictions, their relationship often becomes more intense and reliant. For example, in stories where they are facing the mystery of Riddle together, they learn to trust each other even more deeply. They might start to rely on each other's unique skills, like Harry's courage and Hermione's intelligence, in a more profound way.
It would likely cause a great deal of strain. Harry would probably feel betrayed and angry at Hermione. Their friendship, which was once strong, would be severely damaged.
Hermione, on the other hand, could become more confident in her leadership skills. In the post - war fanfic, she may take on more responsibilities in the wizarding community. With Harry by her side, she realizes that she can make a real difference. Her character grows from being the brains behind Harry's operations to a leader in her own right. She also becomes more open - minded about different ways of magic, as she and Harry explore new areas of the wizarding world together.
If Hermione was Harry's sister, the relationship between her and Harry would be more family - oriented. Ron might initially be a bit jealous as he has to share his two best friends in a different way. But overall, they could form a really strong trio with a new family - like bond.
They would become more reliant on each other. Their relationship would shift from just being friends to co - parents. There would be a deeper level of intimacy and shared responsibility.
At first, it might start with simple moments of realization. Harry begins to notice how Hermione's presence makes him feel more at ease in different situations. As the story progresses, they might have deeper conversations that lead to a stronger emotional connection.
Their relationship could become deeper. Meeting Hermione's relatives would mean Harry is getting more involved in her personal life, which might make them closer. They would share more experiences related to her family, and this could lead to more understanding and trust between them.
Their relationship would shift from a purely platonic friendship to a deeply committed partnership. Harry would become more protective of Hermione, not just as a friend but as the mother of his child. Hermione would see Harry in a new light, as a co - parent and a life - long partner. They would have to communicate on a different level, sharing not only their thoughts about the baby but also their hopes and fears for their future as a family. There would also be some awkward moments as they adjust to this new dynamic, especially in front of their old friends who are used to seeing them as just friends.
In the original series, their friendship was built on a foundation of trust and common goals, like fighting Voldemort. In a married fanfic, that trust would be even deeper. They would be more involved in each other's daily lives. For instance, Hermione might be more involved in Harry's Auror work, giving him advice on how to handle certain magical cases. And Harry would be more involved in Hermione's efforts in the Ministry of Magic for the betterment of the wizarding world. Their relationship would be a blend of love, friendship, and partnership, which is different from just the friendship they had before.
Well, they'd be closer in a more family - like way. In the original, they're good friends, but if raised together, they'd have that sibling - like bond. They'd probably be more protective of each other right from the start. For instance, Harry might not be as hesitant to ask Hermione for help as he sometimes was in the books, and Hermione would be more likely to mother - hen Harry.
