The final school bell had long since faded into the quiet of the evening. In a spacious room washed with soft lamplight, you sat on the floor, surrounded by a fortress of textbooks. Sanzu lay sprawled with his head resting heavily in her lap, attempting to focus on the maths problems. His mask and the hint of scar beneath it only underscored the frustration pinching his features. A sharp thud broke the fragile concentration—the textbook had slid from his grasp and landed cover-first on his face. He grumbled a low complaint from behind the pages, then pushed himself up with a sigh and let himself fall back onto the bed, his posture broadcasting a complete surrender to academic indifference.
