In a non - Twilight - based setting, they could be in a modern city setting. Alice's ability to see the future could help them in business or some sort of high - stakes competition. Their relationship might start as a partnership and gradually turn into something more romantic as they rely on each other more and more.
They could be in a post - apocalyptic world. Alice's foresight would be crucial for survival, and Bella could provide the human element of compassion. Their relationship could develop as they fight together against various threats like mutated creatures or other desperate survivors, and they realize they are each other's most important ally.
The relationship could develop in a rather tumultuous way. Given that they come from such different backgrounds, there would be a lot of resistance from their respective communities. However, their individual natures of being brave and determined would drive them to fight for their relationship. They might start off as friends, gradually realizing that they have stronger feelings for each other. But they would constantly have to prove to others that their relationship is not a threat but a force for good, which in turn would strengthen their bond.
The relationships could develop through shared adventures. They could go on a journey to find a lost vampire artifact or to rescue a captured vampire friend. During these adventures, they would learn more about each other's strengths and weaknesses. Bella's tenacity, Rosalie's beauty and strength, Alice's foresight, and Esme's motherly love would all play a part. As they face danger together, their bond as mates would become stronger and more complex.
Perhaps they go on a journey to find out more about their relationship's origin. They might travel to different vampire clans around the world to seek answers, facing all kinds of adventures and challenges along the way, and in the process, their bond grows even stronger.
After the kiss, they might become closer friends. They could start to confide in each other more. For instance, Bella might share her insecurities about being human among the vampires with Alice more openly, and Alice could share more of her visions that are related to Bella's future.
If they were in a modern city setting, their relationship might develop in a more secretive way. Jacob would have to be careful not to shift in public, and Renesmee would have to hide her vampire - like abilities. They could meet in cafes or at the movies, trying to have a normal relationship while constantly being on guard. This would add an element of mystery and danger to their relationship.
Another way their relationship could develop is through Naruto teaching the Fem Kyuubi about human emotions and relationships. He could introduce her to his friends, and she could learn how to interact in a more human - like way. This would bring them closer as she becomes more integrated into his world, and her love for him would deepen as she experiences all these new things with him.
In an alternate universe, their relationship could start as a friendship based on mutual respect. Felix might admire Bella's courage in the face of danger, and Bella could be intrigued by Felix's strength and loyalty to the Volturi. This friendship could gradually turn into a deeper emotional connection as they face various challenges together.
Their relationship could start with hostility. Masquerade is often a mysterious and somewhat menacing figure, and Alice might be suspicious of him. But as they interact more, especially in the context of Bakugan battles, they could gradually develop a grudging respect for each other's skills. For example, if they keep facing off against each other in battles and each time they learn something new about the other's strategies.
Their relationship could start with mutual curiosity. Arthur is used to the underwater world and Bella is from a world of vampires and werewolves. They would have to learn about each other's cultures and abilities. As they spend more time together, they would develop a deep trust. For example, Arthur might show Bella the beautiful coral reefs in his world, and Bella could introduce Arthur to her friends in Forks. This sharing of their worlds would bring them closer and strengthen their bond as mates.
Their relationship might start with a lot of hostility. Hermione, with her strong sense of justice, would be very wary of Lucius, who has a history of being on the wrong side. But as they interact more, Lucius could be intrigued by Hermione's intelligence and courage. He might start to change his ways to impress her, and Hermione could see the potential for good in him.
