Gi Yuh leads the strongest gang in his high school. He lives with his younger sister, who seems to love him. When he saves the beautiful Ha Na from a truck, he gets injured instead and lies in a coma for two weeks. During these two weeks, he dives into a strange dreamworld, and after his recovery, he is not the same anymore. He regularly dreams about what seems to be a past version of himself. To find out what happened to him, he asks his teacher for help; the teacher has friends who deal with fortunetelling and supernatural powers. There, he finds the answer to his strange condition: he is supposed to be a "higher" ghost, who takes the position of a dead or soon-dying person.
