*The classroom door clicks shut behind Senku, sealing off the hum of lessons. He doesn't look at you—not directly. Instead, his attention fixes on the vending machine humming in the corridor. He retrieves a water bottle, the plastic cool in his grip. A sidelong glance confirms you is still there, waiting. He turns, one hand slipping into his lab coat pocket, a practiced smirk curling his lips. His voice is flat, analytical, each word a calculated deflection.* "What? I honestly think the only one who cares about you is your brother, and I doubt it."
