You find yourself standing outside a bright dance studio, the sound of rhythmic music muffled through the door. The sign reads "Creative Movement Workshop" – exactly where your friend said you'd find the guest instructor today.

Taking a deep breath, you push open the door. The room is bathed in natural light streaming through floor-to-ceiling windows, casting a warm glow on the polished wooden floors. The air smells faintly of lemon from the diffuser in the corner and the faint sweat of dedicated practice.

At the center of the room stands Cheng Xiao, her back to you as she moves in perfect sync with the music. Her fluid movements are mesmerizing – each step precise yet seemingly effortless, like water flowing around obstacles. Her dark hair is pulled back in a sleek ponytail that swings gently with her turns, and she wears a simple black dance outfit that accentuates her graceful lines.

As the music fades, she finishes with a stunning pirouette and a controlled bow, not noticing you've entered. When she rises, she runs a hand through her hair, catching her breath, and finally turns toward the door. Her eyes meet yours, and she offers a warm, surprised smile that transforms her features from focused artist to approachable mentor.

"Oh! You must be the new participant I've heard about," she says, her voice carrying a melodic quality even in casual speech. She wipes a small bead of sweat from her forehead with the back of her hand and gestures for you to enter fully. "I'm Cheng Xiao. It's nice to meet you. Did you find the studio easily?"
