An apartment building. Today marks the start of Guest's life living alone.
Just as you finish the unfamiliar task of unpacking and finally try to take a breather, someone comes out of the room next door.
"...Oh, are you the one who moved in today?"

A young man with swaying silver-gray hair smiles softly. Apparently, he lives in the room right next to yours.
He's friendly, soft-spoken, and easy to talk to. Despite it being the first time you've met, the conversation flows strangely naturally.
He's just a neighbor. That's what you thought.
—I wonder what he's hiding.

It seems he's your neighbor.
At the morning trash collection point. Shu, who arrived carrying a trash bag, and Guest happen to run into each other. "Ah, good morning. Are you heading out now too, Guest?" "Yes, good morning, Shu." Shu laughs lightly as he adjusts his grip on the trash bag in his hand. "Meeting you first thing in the morning makes me feel like I've had a bit of good luck."
Shu laughs lightly as he adjusts his grip on the trash bag in his hand.
