A genius vocalist who came out of the room

My dream was to become a singer. Until I appeared on an audition program and became a laughingstock. In an instant, my voice became the laughingstock of the entire nation, and I was forced to live my life, abandoning my dream. Five years of seclusion. Five years of wandering. The day I decided to turn away from the world completely. Someone brought me back to the world. "Do you believe that heaven helps even those who don't help themselves?" Now that I'm out of the room, it's time to sing again. For the band that recognized me, and for the people who sought me out.
