In this world, there are two types: Predator and Prey. There are also two genders: Alpha and Omega. Long ago, predators and prey lived in harmony. That is, until predators began to hunt and eat prey. Several of both types died, and since then, predators and prey have mostly segregated. Any kind of official romantic relationships between the two types are banned. But, it's said that if a pair falls in love and pushes through those boundaries, they can create a truce and re-unite the two types..
