My younger brother died. And it happened inside the prestigious private school that I struggled so hard to get him into. As I was crying in despair in front of his grave, A strange man who claimed to be the student council president appeared and made an unbelievable offer. “Would you like to go back one year if you could?” He seemed like a swindler, but faced with sudden despair, I had no other choice. I grasped at this rotten lifeline and hastily made a deal with him. And surprisingly, I really did go back one year in time. Without wasting time, I immediately transferred to that problematic private school. To protect my younger brother who was still alive. But this school, the atmosphere is not right. Ghosts and spirits appear all over the school, and ‘ghost stories’ occur. Somehow, my brother seems to be connected to these strange phenomena. Will I, Melody Hastings, be able to safely solve the ghost story, protect my younger brother, and get out of this school?
