To develop their relationship, start with small interactions. A simple smile or a short conversation in the corridor can be the beginning. Then, gradually build on these. Have the OC offer to help Hermione with something she's struggling with, like carrying her heavy books or giving her advice on a difficult spell. As their friendship grows, introduce moments of jealousy. Maybe another character shows an interest in Hermione, and the OC realizes he has deeper feelings for her. This can lead to a more intense and romantic relationship. Also, give them some special moments, like a midnight walk under the stars in the Hogwarts grounds where they share their dreams and fears.
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.
The relationship could also develop through a series of misunderstandings and reconciliations. They might misinterpret each other's actions at first, leading to some tension. But as they clear up these misunderstandings on the train rides, they grow closer. Eventually, all the pent - up emotions lead to that kiss on the train as a way of finally expressing their true feelings.
In some fanfictions, their relationship might start with Harry being initially afraid or cautious of Hermione's new succubus form. But as he gets to know that she is still the same Hermione deep down, they start to build trust and their friendship evolves into something more, like a romantic relationship.
Their relationship might start with them being comrades in arms. After the war, they would have more time to really talk and understand each other on a deeper level. This would lead to romantic feelings.
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.
At first, it might start with curiosity. Harry is used to his wizarding world, and the Muggle is something new. They might meet by chance, like in a park or a coffee shop. Then, as they get to know each other, they start sharing their different worlds. Harry might show the Muggle some simple magic tricks, and the Muggle might introduce Harry to Muggle hobbies.
At first, they might be cautious of each other. Aragorn, coming from a world of swords and battles, might not fully trust magic. Harry, on the other hand, might be wary of Aragorn's warrior - like nature. But as they face challenges together, they would start to respect each other. They could learn from one another's strengths, like Aragorn teaching Harry about physical endurance and Harry showing Aragorn the power of friendship and magic in a different light.
Their relationship might develop into a deeper friendship. Living in Potter Manor together gives them more time to understand each other on a personal level. They could support each other through any challenges that come their way in the wizarding world.
It could become very close and trusting. They'd know each other inside out and have a deep bond from childhood.
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.
