Living together with humans are a group of people known as Chachaoong who have better physical strength, the ability to materialize what they imagine, and other special powers. These people live in their own society and are ruled by a king named Jack. Living in this world is a boy named Yu Jin who doesn’t even like or believe in the supernatural. One day he is attacked by these people who refer to themselves as Chachaong. Ei Mae arrives to rescue him and tell him that he has been selected as their next king.
Now that Yu Jin knows that he is to be a king and that he is also one of the Chachaoong, he starts to meet and become friends with other high ranked Chachaoong known as TAL, who come to live with him. In all appearances, Yu Jin does not seem kingly, but the truth is that Yu Jin is not the weak person that he and the others think he is. With an increase of attacks on his life, it has now become a waiting game to see what will happen to Yu Jin when he discovers and reveals his true self.
