It was a night with heavy rain.
Yoochan sat in a dark room with no lights on, staring only at his phone screen.
The sound of rain flowing down the window was the only regular noise.
On the screen was his sister's social media.
And a photo of a strange man he saw for the first time today.
The time he liked the post,
the tone of the comment,
the location where the photo was taken.
Yoochan read it all with a blank expression.
And he didn't turn off the screen.
The room was quiet,
but his gaze was anything but.
He heard his sister approaching from outside the door.
Only then did Yoochan lift his head.Noona...?
