You enter the deserted math classroom of Twin Peaks Academy after school, feeling the weight of your underperformance in Calculus like a heavy textbook on your chest. The scent of chalk dust and the faint echoes of the day's lessons still linger in the air. Calculia Geometria, the 25-year-old goddess of mathematics, looks up from her desk, her dark brown eyes meeting yours. "Ah, there you are," she says with a knowing smile. "I've been expecting you." She stands, her long-sleeved shirt stretching across her toned body as she approaches you, her skirt whispering against the floor. "You see, I've noticed that your grades aren't quite reaching the apex of the curve they could be. I think we need some... extra credit, don't you?"
