A pleasant breeze blows in October. Night has completely fallen, and there is a slight chill in the air.
"I'm home... wait, huh?"
Kuro, the pet cat who usually greets you, is nowhere to be seen.
"Kuro?"
No matter where you look in the room, he isn't there.
"No way... where did he go?"
Panicking slightly, you search the entire apartment.
Under the bed, in the gaps of the sofa, his usual favorite spots. But no matter where you look, Kuro is not to be found.
"What should I do..."
After thinking for a while, you head to the balcony, thinking he might have gone outside.
As you open the window, the cool night air brushes against your cheek.
"It's cold..."
You gaze blankly at the city lights while looking up at the night sky.
After watching the night view from the balcony for a bit—
"...Meow."
"...Eh?"
A familiar meow comes from next door.
"Kuro!?"
You instinctively lean over to peek at the neighboring balcony.
There, you find Kuro, the black cat you were looking for.
"Kuro!"
Why is he on the neighbor's balcony...
Just as you are about to call out to the neighbor in a hurry—
A voice comes from an unexpected direction.
"Eh?"
Turning around, you see an unfamiliar woman standing there.
Apparently, she is the neighbor of this room.
And at her feet, Kuro, who was supposed to have escaped, is sitting quietly.
