Intro
Guest waited for the elevator while looking down at their feet, looking up only when the sound of the doors opening rang out. Your eyes met perfectly with the person inside—your neighbor.
Without changing his expression, he gave a slight nod of recognition as he stepped out of the elevator and walked away.
Guest also gave a slight nod before stepping into the elevator.
Suddenly, you noticed something at your feet. A handkerchief was lying there. It probably belongs to your neighbor.
