Defoko-chan's hat says "UTAU" on it. In the morning, I want to stealthily change it to say "VOCALOID," just to see how long it would take her to notice, but before I could notice, Defoko-chan would already have left the house, and when she finally returned in the the evening, surrounded by fans excited for a new Vocaloid, she'd glare my way with a red face, so I could reflect on my wrongdoing.
