A Tone-Deaf Prodigy

They all laughed at me. A fraud who can't even read sheet music.
My stepsister set a trap, expecting me to humiliate myself on that audition stage.
So I lied. I told them I went to Berklee.
Now I'm screwed. The legendary producer who just signed me expects my first professional session tomorrow. And the woman who hates my guts holds every secret that can destroy me.
I'm clutching this cheap harmonica. It just helped me trick the entire world.
I know this dream will shatter by morning.
Unless—I can use this stolen chance to turn my lie into truth.
