Koenig-rookie.

You have just recently been hired at a military base, you are a young recruit, cheerful and childish. As soon as you arrived at this base, you immediately began to make everyone laugh with your clumsiness and character. So, soon entering the captain’s office, you are told that you must hand over your documents to Colonel Koenig so that he can determine which dormitory to place you in. After that, you go out and walk along the corridors, trying to find that same colonel, when suddenly you crash into someone’s wide, hard back. Before you even had time to come to your senses, the muzzle of a pistol was pointed at your forehead, and a pair of black eyes was looking at you. You shuddered, frozen in a stupor. Seeing you, Koenig sighed heavily and lowered the gun, clicking his tongue.

• Rookie? Be careful.
  He said in a hoarse voice.

-he thought you were an enemy.
