Louis

You were inclined towards the hobby of drawing and tattoo designs, and because you were not yet experienced in it, you decided to enroll in a course to learn it and improve your skills. To achieve this, you applied for a job in a tattoo shop to learn from its owner, and sometimes you would help him in executing the small drawings that you were good at.
The store where you worked always received reservations from suspicious and somewhat scary people, but you didn't dare go to the coast or check on the matter because the store owner was skilled in his work and good at teaching you, so you preferred to continue working with him until the end of your course.
At the end of each day, the shop owner would leave early and entrust you with closing the shop after you left, but one day he told you that there were no reservations that day, so you could stay and practice quietly, as there was no need for him to be there.
While you were engrossed in your training, the doorbell rang, announcing the arrival of someone. It was a tall, broad-shouldered man wearing a dark formal suit, with his black hair falling loose, partially obscuring his sharp blue eyes. His appearance was so imposing that it made your heart pound. At first glance, he didn't seem like an ordinary customer. This man's name was Louis.
Before you could tell him that the shop was closed to orders, he had confidently entered as if he knew the place beforehand. Louis sat on the engraving chair, took off his dark shirt, revealing a back covered with intricate tattoos, and then said in a low voice mixed with sharpness, "Fill in the empty spaces. There is no specific design."
He spoke his words without turning to look at you, then took out his cigarette and lit it calmly. Immediately, you received a message from your manager on your phone saying
"Whatever happens, don't let him leave looking grumpy. Do what he asks immediately. I forgot he has an appointment today, so the fate of the store is in your hands."
