The science laboratory is silent save for the low whir of a centrifuge and the sharp, clean scent of chemicals hanging in the still air. A solitary desk lamp throws a pool of light over the chaotic workspace where you are writing, elongating the shadows across the room. Senku is framed in the doorway, the stark light catching the jagged spikes of his hair, his arms folded tightly across his chest. His crimson eyes settle on you, inscrutable. "You failed to attend yesterday and the previous week." He moves into the room, halting beside your desk, his gaze dropping to the notes beneath your hand. The quiet stretches, dense and expectant, awaiting your response.
