Their relationship might develop through a series of challenges. For example, they could be forced to participate in a magical tournament together. In order to win, they need to trust each other completely. Manon has her own set of combat skills and Dorian has his magic. They must learn to combine their abilities. At first, they bicker and argue about strategies, but as they see the effectiveness of working together, they start to respect each other more. This respect then turns into admiration and finally love. Along the way, they also have to deal with the politics and prejudices of their respective worlds that try to keep them apart, but they fight against it and their relationship grows stronger.
One plot idea could be that Manon and Dorian are forced to team up on a quest to retrieve a powerful magical artifact. Along the way, they start to understand each other's cultures better. Manon learns about Dorian's courtly life and Dorian discovers the ways of the Ironteeth witches. This could lead to a slow - burn romance as they see different sides of each other.
Their relationship could develop further through shared challenges. For example, if they had to face a powerful enemy together, they would learn to rely on each other more. Celaena's fighting skills and Dorian's magic would complement each other, and this would bring them closer.
In a rural setting, away from the politics and battles, Aedion and Lysandra's relationship could become more peaceful and domestic. They might enjoy simple things like farming or taking care of animals together. The slower pace would allow them to focus more on each other and less on their duties.
In a Throne of Glass fanfiction where Aelin is a sex slave, the story could develop in many ways. One way could be her finding inner strength to resist. She might use her wits and any small advantages she has in her situation to gradually undermine those who hold her captive. For example, she could befriend a guard or servant who then helps her in some way.
Their relationship could develop further through shared adventures. For example, if they go on a quest together, they'll have to rely on each other, which will deepen their bond.
Well, it could develop in a really comical way. Imagine Tatsumaki trying to teach Saitama some 'proper' hero etiquette, but Saitama just doesn't get it. However, through these interactions, they start to understand each other better. Tatsumaki sees Saitama's kindness and Saitama sees Tatsumaki's determination. This mutual understanding could lead to a unique relationship in the fanfiction.
Their relationship could develop in a more complex way if Black Goku somehow gets trapped in a situation where he has to rely on Chichi. Maybe he loses his powers temporarily and Chichi has to take care of him. During this time, she might try to instill some of Goku's good values in him, and he might start to have a soft spot for her. This could lead to a very unusual relationship dynamic where Black Goku is torn between his evil self and the positive influence of Chichi.
One more theme that pops up often is the idea of transformation. Dorian has his own journey of self - discovery and transformation, and Manon also goes through changes. In fanfiction, these transformations can be intertwined. For example, they might help each other become better versions of themselves, learning from each other's strengths and weaknesses.
In a fanfiction, their relationship might develop slowly. At first, they could be rivals in a magical competition. Hermione is using her book - learned knowledge, while Abraxas is relying on his family's ancient magical secrets. As the competition progresses, they start to notice each other's skills. Abraxas might start to question his family's prejudices against Muggle - borns when he sees how brilliant Hermione is. They could then start to communicate more, sharing magical theories, and over time, a deep bond could form between them.
Well, their relationship development could be a complex journey. Maybe Rhaella is initially in a position of power and Jon is a nobody in her eyes. But as events unfold, Jon shows his courage and leadership skills. Rhaella starts to respect him and realizes that he could be an important figure in the future of the Targaryen dynasty. They could start to collaborate on plans to strengthen the Targaryen claim to the Iron Throne. Their relationship would be filled with political intrigue, personal growth, and a growing sense of loyalty towards each other as they face various challenges together.
