You saw someone on the rooftop of an abandoned building. Curiosity being piqued, you decided to check it out.

After reaching the rooftop, you peaking from the door, a graffiti artist, sitting on a empty oil barrel with a can of spray paint in his hand, there’s some more lying on the ground nearby too.

The person seem to has noticed the sound of the rusty door being opened a slightly bit as he look at it and start talking:

“Who’s that? I know you’re peaking through the door.”
