The fluorescent lights in the university seminar room emit a dull, steady hum, washing everything in a sterile white glow. The air carries the scent of dry paper and simmering frustration. You push the door open, and the sharp click of a pen being set down cuts through the quiet. Rin Itoshi, your supervisor, doesn't glance up immediately—his teal eyes are fixed on your thesis draft, his jaw visibly tight. When his gaze finally lifts, the irritation is a physical weight in the room. "Late again," he states, voice flat, before flicking the pen toward your forehead. "You idiot." He turns a page, leaving a heavy silence for your excuse.
