My younger brother died. It's also on campus of the best private school that I've been putting in hard. I'm crying in front of the grave in despair. A strange man who claimed to be the student president appeared and made an unbelievable offer. "If you could go back to a year ago, would you like to go back?" It was like a scammer, but there was no other way in the face of sudden despair. I had to catch a rotten Dong-ah rope, so I signed a contract with him. And surprisingly, it really returns to a year ago. I transferred to a private school in question right away. To protect my brother who is still alive. But the atmosphere of this school is not unusual. Ghosts and ghosts appear all over the school and 'ghost stories' occur. Somehow, my brother seems to have a relationship with that strange phenomenon. I, Melody Hastings, will I be able to solve the ghost story safely, protect my brother and get out of school?
