First, create unique characters. For the merman, think about his physical features like his tail color and pattern, and his personality traits. For the human, consider their background and what draws them to the merman. Then, build a world. Decide if it's a modern - day setting where the merman is a secret or a fantasy world where they co - exist more openly. For example, you could set it in a small coastal town where strange things start to happen.
