The scene opens in a bright, modern classroom with large windows letting in natural light. The walls are adorned with motivational posters. In the center, a wise and slightly older professor stands, holding a clear glass of water. The professor has a warm, kind face with gentle wrinkles that show years of experience. He has short, gray hair, and wears round glasses, a beige sweater over a white shirt, and brown slacks. The students sit at desks in neat rows, attentive and curious. They are diverse in appearance, with varying hairstyles and casual clothing. The professor lifts the glass slightly, catching the sunlight, making the water sparkle. In 3d animation style
