A unique way to develop their relationships is by having them all be cursed in a way that they can only communicate telepathically. At first, they're frustrated with each other, but as they learn to live with it, they start to understand each other's thoughts and feelings on a deeper level. Draco discovers that Harry and Hermione aren't as bad as he thought, and Harry and Hermione realize that Draco has his own insecurities and pressures. This forced closeness helps them build a more complex and nuanced relationship.
Their relationships could be developed uniquely by having them participate in a magical tournament that's not like the Triwizard Tournament. They are on different teams but have to cooperate secretly to overcome some corrupt judges. Draco might start to see Harry and Hermione in a new light as they work together to expose the wrongdoings. This shared experience outside of the normal Hogwarts rivalries can bring them closer.
One way is through a time - travel plot. Say, they all get sent back to a time when their families were involved in some major wizarding event. Draco sees his family's past actions in a different perspective, and Harry and Hermione get to understand the Slytherin side better. They have to rely on each other to not disrupt the timeline while also learning from the past. This could lead to Draco having more empathy towards Harry and Hermione, and for them to see Draco as more than just a Slytherin bully. As they return to their own time, their relationships are forever changed.
Their relationships could develop through shared experiences. For example, if they are all part of a special project at Hogwarts. Harry and Hermione are already friends, and as they work with Susan, they start to see her as an equal. They might bond over late - night study sessions or during dangerous encounters while exploring the school's secrets. Harry could come to respect Susan's quick thinking, and Hermione might admire Susan's determination.
Their relationships can start with rivalry. Draco and Blaise, being Slytherins, might initially see Hermione as a know - it - all Gryffindor. But as they interact more, they notice her loyalty and courage. For example, in a situation where they are all in danger in the Forbidden Forest, Hermione's quick thinking saves them. This makes Draco and Blaise reevaluate their views of her, and slowly a friendship can start to form.
Their relationship could develop through a shared love of potions. Harry discovers he has a natural talent for it, much to Snape's surprise. Draco, being a traditional Slytherin, also excels in potions. They start to compete in a friendly way, which then turns into a mutual respect for each other's skills. This could lead to them working together on a special potion project that requires both Gryffindor - like boldness (from Harry) and Slytherin cunning (from Draco).
For Hermione, you could develop her character by having her be more conflicted about the use of magic. Meeting Gellert, who has such extreme views on magic and power, could make her question her own Hogwarts - taught values. For Gellert, instead of just being the 'evil' character, show his more human side. Maybe he has regrets deep down. For example, Hermione could find a way to communicate with his past self and see his early dreams that were not so dark.
Their relationship could be developed through a shared love of transfiguration. Hermione could seek out McGonagall for extra lessons and in the process, they bond over the beauty and complexity of the subject.
Another way is through a shared danger. Suppose there's a new threat in the wizarding world that endangers both Slytherins and Gryffindors. Malfoy and Hermione, along with Harry, have to put aside their differences. In the face of this danger, Malfoy might have a change of heart and begin to respect Hermione. Their relationship could develop from grudging allies to something more like friends. This could be a slow process, with many bumps along the way as they both struggle to let go of their preconceived notions.
For Naruto and Hinata, their relationship could develop in a unique way if Hinata starts teaching Naruto some of the more refined aspects of the Hyuga clan's techniques. This would create a new level of closeness as Naruto respects Hinata's skills. And with Tenten, she could be the one who arranges little 'get - togethers' for the three of them, which slowly builds a stronger bond between all of them.
Their relationships can be developed uniquely by having them participate in a mission that requires them to rely on each other's skills in unexpected ways. For example, Ino's mental abilities, Naruto's brute strength and positive energy, and Sasuke's strategic skills could combine to solve a mystery that has been plaguing the village. This would force them to respect and trust each other more.
In some fanfictions, the werewolf knots might have a magical influence on their emotions. So, Harry and Draco could find themselves having unexpected feelings for each other. Their relationship then develops as they struggle with these new emotions while also dealing with the stigma and danger associated with werewolf knots in the wizarding world. It's a complex process that involves a lot of self - discovery for both characters.
In fanfiction, Draco and Hermione's friendship can be really interesting. One way it can be depicted is through a series of accidental meetings outside of Hogwarts. Maybe they run into each other in Diagon Alley and initially have a tense encounter. But then, they start to have conversations that make them realize they're not so different. For instance, they might both be interested in a particular type of magic that is not well - known. This common interest starts to bridge the gap between them.
