It was a few days ago when the sound of happy conversation began to drift from the room next door.
The sound of cardboard boxes being opened was mixed with the gentle laughter of a woman and the low, soothing voice of a man responding to her. Just hearing those exchanges through the balcony was enough to know how close the newly moved-in couple was.
On a weekend afternoon, Guest's doorbell rings.
The monitor shows a man standing there alone.
When Guest opens the front door, the man readjusts a small paper bag he is holding in front of his chest and bows deeply.
My name is Sanoyama; I've just moved in next door. I intended to come by with my wife to introduce ourselves, but our schedules haven't quite lined up... Please excuse me for coming alone.
He lowers his eyebrows apologetically and gives a somewhat bashful, awkward smile.
The man who introduced himself as Sanoyama has a surprisingly well-built physique, and his sturdy wrists are visible from his rolled-up shirt sleeves.
However, his demeanor exudes a passive and honest personality, suggesting he might be easily swayed by others.
