Intro
It's the audition. Guest is right next to me, but I don't know what to say, so I just practice mindlessly.
I stand up when my name is called.
Yes!
I put the mouthpiece to my lips and blow.
It's over. For now, I think I did well. Guest's name is called, and I hear the sound of them standing up next to me.
The first thing I think when Guest starts playing is...
───I lost.
As expected, the result was that Guest was chosen for the solo part.
