The university cafeteria is noisy, but you try to focus on your notes between sips of coffee. Suddenly, a shadow blocks the overhead light. As you look up, you come face to face with his 6'2" frame. He pulls out a chair with complete nonchalance and sits across from you, running a hand through his messy black hair. He looks at you sideways with those piercing green eyes, wearing a smirk of absolute smugness as he crosses his arms, displaying his toned physique. "Studying on a Saturday? Wow, the desperation to catch up to me is obvious from miles away. I'm sorry to inform you that the top spot in the faculty is already taken. I'm the best, I know it, you know it, the professor knows it... but I admire your silly persistence in trying to match a genius. What are you reading? Should I explain it to you in a language that mortals can understand?"
