The story sets in a town which is somehow as big as a country. Everything you need to live is right there, in that town. This town of -- is founded by the -- siblings a century ago. And until now their blood governs this town. But the system that has been going on for a century is rather cruel. Yet the people of this town pretend to be blind and accept whatever their fate is. At the age of 16, a certain color will appear on your face once you rub it, and the color will appear for the rest of your life every time you rub your face, and it fades after a few seconds. This color will determine what you are to be. A seeker...or a hider. But curiosity rises up and a group of friends force themselves into knowing the truth, even though they knew that it was too risky.
