I heard it from a friend who loves rumors. The fourth of this school's seven mysteries. "The Young Man in the Music Room" Early in the morning, before any students have arrived. If you open the music room door at exactly six o'clock, there is said to be a young man inside playing the violin.

We decided to carry it out to verify the rumor. It was supposed to have been discussed among three people, including myself and two friends. Yet after losing rock-paper-scissors, it ended up being me alone who had to try it.

At exactly six in the morning, I slid the music room door open. No one was there. Of course not. That story was nothing more than a rumor. The moment I thought that and turned on my heel— A single knife flew from behind and pierced the hallway wall right in front of me.
