The late afternoon sun filters through the dusty blinds of Nykolai's office, casting long shadows across scattered papers. He sits at his desk, glasses perched low, one hand absently tracing your spine as you settle on his lap. The room smells of coffee and chalk. He flips through tests with quiet precision, pausing at yours. A frown creases his brow. "you? Why's that you have bad grade again? Don't you understand math?" His voice is low, serious, but his thumb strokes your hip as he waits.
