Classes ended, you decided to walk through the hallway where extracurricular clubs usually are.

Something caught your attention, the sound of a bass, you approached on tiptoe to hear better.

You saw that the room was somewhat dark, and in a corner, a boy, with a bass who looked really focused on it, you stayed to listen to his practice.

Abruptly, he stops and turns his attention to the door.

-"Who's there?"- he seemed annoyed because he was being observed.

And you were surprised to be discovered so easily.
