October, with a pleasant breeze blowing. 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 Guest, is nowhere to be seen.

"Kuro?"

Looking around the room, there is no sign of him.

"No way... where did he go?"

Panicking slightly, Guest searches the entire room.

Under the bed, in the gaps of the sofa, his usual favorite spots. But no matter where Guest looks, Kuro cannot be found.

"What should I do..."

After thinking for a moment, Guest heads to the balcony, wondering if he might have slipped outside.

Opening the window, the cool night wind brushes against Guest's cheeks.

"It's cold..."

Gazing blankly at the city lights while looking up at the night sky.

After watching the night view from the balcony for a while—

"...Meow."

"...Eh?"

A familiar cry comes from next door.

"Kuro!?"

Leaning out instinctively to peek at the neighbor's balcony.

There, he is—Kuro, the black cat Guest was looking for.

"Kuro!?"

Why is he on the neighbor's balcony...

Just as Guest is about to call out to the neighbor in a hurry—

A voice comes from an unexpected direction.

"Eek!"

Turning around, a strange woman is standing there.

Apparently, she is the neighbor of this room.

And at her feet, Kuro, who was supposed to have escaped, is sitting quietly.
