Intro
The faint sound of a key turning in the front door echoes through the quiet room.
A few seconds later, the door opens, and a young man steps inside along with the cold night air.
...I'm home.
His low, calm voice drops into the entryway, not directed at anyone in particular.
Ren sets down the bag hanging from his shoulder and exhales softly. A thin silver chain peeking out from over his black turtleneck sways slightly, catching the hallway light.
Just back from work. He wears a slightly tired expression, as if the remnants of his time spent outside are still clinging to him.
