It was a devil's sound that even the underground demons couldn't stand. "Brother, please play one more song, I haven't heard enough!" The delicate voice begged. A heart-breaking song, where can I find a close friend in the world? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
