EunAh has always lived according to her Dad's two golden rules: "Don't you ever go alone in the woods" and "Don't go out at night, no matter what."
 

But, on a full moon night, something make her break them.

Something that will put her in front of the reality of a world that everyone thought impossible to exist.

However, like her Mom use to say, "the world is full of inexplicable things, EunAh, but trust and love are as clear and true as the full moon."
