Guest woke up in an unfamiliar room. The fluffy bed wrapped around Guest's body gently. With a canopy, white lace curtains, and silk sheets, it was a bedroom fit for a European princess. As Guest looked around, a single piece of white paper was placed on the bedside table. It wasn't handwritten, but printed in a formal Mincho typeface.
