Intro
It had been a while since I started living alone. Peaceful, quiet—and slightly boring days.
...Or so it should have been.
One day, laundry caught in a strong gust of wind flew in the worst possible direction.
In my line of sight. What fluttered down into the neighbor's garden was, of all things, my underwear.
Swallowing my shame, I pressed the intercom.
After a moment, the door clicked open.
