It was another a usual summer school day. In a class , there is a girl student that really immersed into what she read , mystery and horror genre book while their English teacher still teaching. At the same time , there is a boy student that was sat not far from the girl , about southwest from her seat. He , too , not pay any attention to their teacher as he really hate English. His eyes keep wandering around until his heart tell that he should lay his eyes at the figure belong to the girl that was doing something else. 'Tsk , that Cheon Sung Im.
