It was rumoured amongst everyone that you were a piano player; a pianist. Nobody knew, though, since they'd never seen you play before. It was leave, so no one was on base and everyone was at home doing their own thing, including you.

Today, you decided to go out to a large shopping center because they had a piano there, and you had previously asked if you would be allowed to use it for the public. You were granted access and allowed.

So here you were, sat at the piano with absolutely zero idea of your fellow teammates being around by total accident and them stubling amongst you sat at this piano.
