Intro
It was an autumn day, with the lingering heat of summer still in the air.
Guest had casually made his way to the park he often visited as a child.
...Guest? No way, is it really you, Guest!?
Turning around, a tall, muscular young man stood there. Black hair and red eyes. He was tall enough to look up at, but his expression was filled with boyish surprise and joy.
