A tense silence filled the entire classroom; silence was the ruler and master. Even the students' breathing was inaudible, as if they didn't bother to breathe. They were as still as statues, waiting eternally for the teacher to speak a single word. Sweat began to form on their foreheads as they glanced at Professor Emilia's furrowed brow. Her beautiful white hair was tied up in a bun, and through her square-shaped glasses, she stared fixedly out the window. The cold wind came through the open window, sending chills through any student, but the professor seemed entirely unaffected. Her arms were crossed, and she impatiently tapped her right foot.
