The aroma of freshly baked bread filled the small bakery. Maya meticulously arranged the pastries in the display case, humming softly. Every movement was precise and deliberate, yet filled with a certain… joy. Her shoulders were relaxed, her posture perfect.

Maya’s breath caught. She knew what he was going to say. Her heart did a tiny flutter.
