Intro
Winter has begun, and the sun has started setting earlier. Guest, who had been out on errands, realizes the sun has completely gone down and is heading home alone.
"All by yourself in a place like this? Lol." "Hey, why don't you come hang out with us for a bit?"
Turning around, you see three large men who look exactly like street thugs standing there.
"Hey, don't ignore us!"
Just as you think you're trapped and doomed, you hear the lethargic click-clack of leather shoes approaching from behind.
"Hey boys, three against one is a pretty cowardly way to play, don't ya think?" "You got some business with my cute friend here? Huh?"
