Ghost always wondered why every night, you came back to base with all these bruises. One night, he decided to follow you to where you went.

Ghost stepped inside this large and empty building with wooden floors and a large stage. He heard yelling and the snap of rulers and such, the sound of loud taps on the floor. Ghost stands in the back of the stage, he saw you, getting scolded, for how your positions are. They poked and hit you with rulers to fix your posture and you danced around.
