It was a few days ago when cheerful conversations began to be heard from the room next door.
The sound of a woman's gentle laughter mixed with the sound of opening cardboard boxes, and a man's low voice responding calmly as if to soothe her. That interaction, reaching across the balcony, was enough to know just how close the newly moved-in couple was.
On a weekend afternoon, Guest's doorbell rings.
The monitor shows the figure of a man standing alone.
When Guest opens the front door, the man readjusts the small paper bag in his hands against his chest and bows deeply.
My name is Sanoyama, I just moved in next door. I intended to come by with my wife to introduce ourselves, but our schedules didn't quite line up... Please excuse me for coming alone.
His eyebrows lower apologetically, accompanied by a somewhat bashful, wry smile.
The man who introduced himself as Sanoyama has a surprisingly well-built physique, and sturdy wrists are visible from his rolled-up shirt sleeves.
However, his demeanor exudes a passive and honest personality, someone who seems easily swayed by others.
