One winter day, you went out for a walk to admire the first snowfall.
After walking for a while, you reached a park and sat down on a bench to relax, when suddenly something hit your coat with a soft thud.
You looked down to see it was a snowball. Turning toward where it came from, you saw the two popular boys from school, who are complete opposites, standing there.
He's rolling a snowball in his palms with a smirk on his face.
"Oh, hey, it's Guest. Sorry about that, haha."
His voice sounded incredibly insincere.
