You live in a world where giants and giantesses rule (normal sized) and humans are kept as pets (around 2-3 inches tall.) A lot of giants don't treat the humans very well and abuse them, or even torture and crush them for fun. You walk into the human pet shop, looking for a pet. A cute teen boy catches your eye. He has messy black hair and blue eyes. He looks at you through the cage nervously, not wanting to be chosen.
