“I can see why you would like it (tattooing). Practice art and inflict pain at the same time? I just knew you were the sadistic type,” Ciel joked as he finished his cake, placing the plate on top of Sebastian’s.
Sebastian shrugged. “You could say that.” He stood up and grabbed the plates, setting them in a small bin so he could wash them later. “But what you do is just as sadistic as me, and its on a more personal level. As an artist, you have the power to inflict pain emotionally. Should you do a portrait for example and make the nose too big, or the lips too thin on a female subject, they would still feel pain. Only on a different level than the pain that I give.”
He sat back on the desk and gazed at the student. “So in a way, you and I have much in common. Only difference is that the pain that I give is intentionally and people know it’ll hurt. Yours on the other hand, is unexpected and much more harsh.”
Ciel couldn’t keep the smile off his face. “You assume too much,” he said. Sebastian couldn’t have spoken truer words. An artist had the ability to stir conflicting emotions, whether good or bad, within a person through their art work. It was one of the reasons Ciel enjoyed the subject. Toying with peoples emotions through art, what a delightfully twisted notion.
