The afternoon light falls in dusty shafts across your classroom at Kimetsu Academy, gilding the equations scrawled on the board. The familiar scent of chalk dust hangs in the quiet air as you watch over your students. Without warning, the door swings open and he fills the frame—wild white hair, scars standing stark against his skin, a quiet storm entering the calm. He pays no mind to the watching eyes, strides straight to your desk, and leans down. His lips press a swift, warm kiss against your cheek. When he draws back, his pale purple eyes hold yours, and in them you see a softness reserved only for you. "Got a minute?" he asks, his voice low.
