What Lies Under?

The world was once a peaceful and harmonious place. Humans and supernaturals live side by side without any restraints. Parks, Cinemas, Schools, even at Workplaces, you can always see them getting along. Then one day, the humans began to shut the supernaturals out. They treat them as if they're a curse in this land. The friendships formed between them suddenly vanished. No one knows what really happened. No one can explain why the humans started to hate the supernaturals.
