demon (exo boyxboy/OT12)

Would you believe there were another world other then earth? No? Well to break your bubble there is actually, it's called "The Demon World" In that world there's nothing but darkness, with the only sign of light is the moon that shines under them...In the demon world ruled six kings of different region, there were many rumors about them...about their cruelty, heartless deeds, and their aura that can make any demon bow in respect of their rulers. But away from the public eyes, these six demons aren't what the rumors seem to be, sure they were cruel, heartless and have a scary aura indeed, but inside the closed doors of their palace, they're only teens wanting to get away from the responsibility of ruling their kingdoms for a while, but it seems papers don't wait for anyone...

Now what would happen if these six kings suddenly get transported to the human world where their proclaimed mates are there? With the help of a guardian, let's see what trouble the six kings would make in the human world with full control of their powers hm?
