Communication is key. If in the fanfiction there is a way for the human and the monster to communicate, either through telepathy or some other means, they can start to understand each other's motives and desires. For instance, the monster might be lonely and the human might be curious, and this can form the basis of a relationship.
One idea could be a giant monster that is actually a gentle being misunderstood by humans. A human befriends it and tries to convince others it's not a threat. For example, the monster might have been protecting a natural resource that humans unknowingly were about to destroy.
The human character can be developed through their relationships. If they fall in love with a monster, for example, they have to navigate the cultural and physical differences. This can show their growth as they learn to accept and be accepted in a world that is not their own. Also, their reactions to the unique events at the university, like the monster - themed sports events, can shape their character.
In this type of fanfiction, character development is key. The human character can develop by learning from the monsters. For instance, if they were selfish before coming to the island but then see the monsters' selfless behavior in sharing resources, they can change. As for the monsters, they can develop based on their interactions with the human. A monster that was always feared by others on the island could become more approachable after befriending the human. This shows a change in its reputation and personality.
Another approach is through a shared goal. Imagine both the yeti and the human are being chased by a common enemy, like an evil wizard who wants to capture the yeti for its magic and the human for some dark ritual. They have to rely on each other's strengths. The yeti's physical power and the human's intelligence work together to outwit the wizard. During this adventure, they come to understand each other's value and a strong relationship blossoms.
First, they need to start with some common ground, like a shared goal or a mutual enemy. This gives them a reason to interact. Then, they can gradually learn about each other's cultures. For example, the human can learn about the Khajiit's moon - based beliefs, and the Khajiit can understand human social hierarchies.
The relationship can start with fear. The human sees the Skullcrawler as a terrifying monster at first. But then, through a series of events like the Skullcrawler sparing the human's life for some reason, the human begins to question their initial perception. They might start to study the Skullcrawler more closely, and as they learn about its behaviors, a sense of respect could develop.
It could start with fear and curiosity. The human is initially terrified of the xenomorph but as they observe it, they notice some unique behaviors. This piques their curiosity and they start to approach it cautiously.
The relationship can start with curiosity. The human might be curious about Luna's powers and appearance as she is a moon princess. Luna, on the other hand, could be curious about the human's different nature. They can start by simply asking questions about each other's worlds.
They could also develop their relationship through shared interests. Maybe they both love exploring old ruins. As they explore together, they start to understand each other better and grow closer. They can exchange stories about their past adventures in these ruins, which deepens their connection.
The relationship can start with a misunderstanding. For instance, Shrek might think Fiona is a snobbish socialite, while Fiona might see Shrek as a brute. But then, a common cause can bring them together. Say a local villain is threatening their town, and they both realize they need to work together to stop it. As they plan and fight side by side, they start to see the good in each other.
