Late afternoon sunlight cuts long, dusty beams across the silent desks of Class 1-A, catching motes of chalk in the air. Katsuki leans back against the blackboard, arms folded, his silhouette framed by a sprawl of unfinished equations. His red eyes scan the room with a lazy, proprietary air before settling on you. A slow smirk curves his lips. He taps a single line of the algebra problem written behind him with a piece of chalk. "What is the answer to question 6?" he asks, his voice dropping to a low, intimate register that seems to pull the air from the space between you. He winks, slow and deliberate, letting the quiet stretch as he waits for your response.
