A really unique way to develop their relationship could be through a time - travel plot. Maybe they both get sent back to a different era in the Upper East Side's history. There, they have to rely on each other to survive and adapt. This would not only test their relationship but also give them a chance to see how their families' legacies have shaped who they are today. They could come back to the present with a much stronger bond.
They could start a secret project together, like building a super - advanced gadget. As they work on it, they share their dreams, fears, and secrets. This shared experience outside of their regular hero/vigilante work can bring them closer.
Another way is by introducing a third party that has a vendetta against both of them. This would force Shirosaki and Ichigo to protect each other, not just because it's the right thing to do, but because they are the only ones who understand the threat this third party poses. This common enemy situation can make their bond stronger as they fight side by side and gradually learn to trust each other more.
The relationship could be developed uniquely if the human has a special ability, like being able to communicate with animals on a basic level. So, they and Dogmeat can have more in - depth conversations that other humans can't have.
In a married Nate and Serena fanfiction, their relationship can be developed realistically by showing how they handle financial matters. Maybe they have different spending habits. Nate might be more conservative while Serena is more of a spender. They need to find a balance. Additionally, family planning can be a big part of their relationship development. Deciding whether or not to have children and when can bring out different sides of their personalities and how they interact with each other.
The relationship could be developed through shared dreams. Every night, Naruto and Kurama enter a dreamscape where they can communicate freely without the interference of the outside world. In these dreams, they gradually open up to each other about their past traumas. For Naruto, it could be about his loneliness as a child, and for Kurama, it could be about his long - held resentment towards humans. Through this sharing, they grow closer.
To develop their relationship uniquely in fanfiction, you could explore a scenario where Cato and Clove are reincarnated from a past life. In this new life, they still have a strong bond that they don't understand at first. As they enter the Hunger Games, they start to remember their past relationship and it changes the way they interact. For example, Cato might be more protective of Clove than he was in his original Games self. Another way is to give them a shared dream or vision. They both see a future where they can change the Hunger Games system together, and this common goal brings them closer. You could also make their relationship more complex by having Cato be jealous of Clove's friendship with another tribute, which then leads to a deeper exploration of his feelings for her.
One way to develop their relationship uniquely is to have a magical object that links their minds. This would mean that they constantly share thoughts and feelings, whether they like it or not. At first, they fight against this connection, but as time goes on, they learn to use it to their advantage and it deepens their relationship. For example, Ventus might use it to reach out to Vanitas when he is in danger, and Vanitas might start to rely on Ventus's positive emotions to fight against his own darkness.
Well, they could be united through a shared love of adventure. For example, they both hear about a hidden magical place and decide to explore it together. Along the way, they face various challenges that force them to rely on each other, thus deepening their relationship.
The relationship could develop through shared experiences like exploring new places. For example, the human could take the Sparkling Arcee to a beautiful natural location on Earth that Arcee has never seen before, and this shared wonder could deepen their bond.
One way is by exploring their pasts more deeply. Maybe they both have some hidden traumas from their childhood dance experiences that they gradually share with each other, which brings them closer. For example, if Christian had a strict teacher in the past who made him doubt his abilities, and Tara had a similar experience but in a different way, they can bond over that.
