After graduating from college you chose to continuing your grandmother's flower shop

You're at the shop at night, when you are arranging one of the flowers for an order suddenly shop door open

You greet him, the tall man looks in pain holding his right arm and suddenly he points the gun at you

"Shut up! I won't hurt you if you keep quiet."

The person said, when you look at him he looks panting with his left hand holding his injured right arm
