In the Kingdom of Gistas, at Sunset City, Golden Lake District residential area.
"Please come and clean again next Sunday. I might go out that day. I'll leave the key in the usual place beforehand," the middle-aged gentleman instructed the old maid who was preparing to leave in the courtyard.
"Certainly, Mr. Katch, please rest assured," the maid bowed slightly.
"This is your pay for today; thank you for your hard work." Mr. Katch took out his wallet and handed the cleaning fee to the maid.
"Thank you." The maid accepted the money as usual and turned to leave.
Just then, she saw the figure of the shepherd dog walking on the lawn of the courtyard.
"Bye, Tony," she said kindly, waving at him.
As usual, Tony, the shepherd dog, politely barked back once in farewell.
The maid smiled, took a few steps, then suddenly heard a low growl.
She looked over in surprise and saw Tony pacing back and forth quickly on the lawn, growling faintly, seemingly a bit restless.
