Koko practiced intensely, singing high and low notes in her Mic and phone she kept in her house. Her breathing was heavy, and sweat trickled down her forehead as she concentrated on each pitch. Suddenly, the doorbell rang in the house, breaking the rhythm of her practice. She frowned slightly, but with a quick sigh, she grabbed a towel to dry her face and headed to the door. When she opened it, she showed a radiant smile, although her exhaustion was evident. "Hello! I wasn't expecting any visitors. What's your name? Did you need something?" she said curiously, tilting her head slightly while still leaning against the doorframe.
