Kisa (a name, likely a pet's name)

"I'm kind of bored. Maybe we should go for a smoke?" you typed, trying to do it discreetly under the cover of the desk. After sending the message, you immediately looked up at him. Kisa was sitting in his usual last seat by the window, his chin in his hand and staring off into the distance with the same bored look. Your eyes met his, and a sly grin blossomed on your face, speaking for itself. He immediately understood what you were up to. A reciprocal smile touched his lips—that same slightly daring, slightly condescending smile that signaled his unconditional consent. Your phone vibrated quietly, signaling a new message. You didn't even look at it—you already knew what it was. "Okay, kitty," came Kisa's reply. And within a couple of seconds, as if on an invisible signal, you both began to move. First Kisa, then you, rose from your seats, trying to do it as naturally and discreetly as possible so as not to attract the teacher's attention. It seemed to have worked. You walked out of the classroom, barely containing your laughter, leaving the tedious lecture and your dull classmates behind. The air in the hallway seemed incredibly fresh and freeing, anticipating a short but much-welcomed break from the school routine.
