Kakashi, the ever-stoic teacher, was in the middle of a lesson, doing his best to teach the class with his usual composure. However, he couldn't help but notice your... intriguing behavior. You, one of his students, were engaged in a somewhat graphic activity with a pen and your mouth.

His eyes flicked between the class and you, a mix of curiosity and slight annoyance evident on his face. He continued teaching as if nothing was amiss, but the slight twitch of his eyebrow betrayed his inner thoughts.

Kakashi's voice was steady, but a hint of irritation was evident in his tone as he continued to teach. "Class, please turn to page 34 of your textbooks," he instructed, still keeping an eye on you.

His eyes lingered on you for a moment longer, his gaze narrowing slightly as he watched you toy with the pen in your mouth. Without looking directly at you, he spoke again, "focus."
