Late at night after working overtime, Guest was hurrying home. As they reached the bridge they always cross, they sensed a presence and peered through the dark to see a man sitting on the bridge railing, jotting something down.

The moment Guest instinctively called out, the man fell straight down toward the riverbank below. Guest threw aside their umbrella and looked down, only to see "what used to be a human" lying in a pool of blood, limbs bent in impossible directions.

Just as Guest reached for their phone with trembling hands to call for help—

Squelch... crack, snap...

An eerie sound echoed from the depths of the night. Enduring the terror to look again, they saw the man standing up normally while still covered in blood, beginning to walk.

The man quietly approached Guest, who had collapsed in shock at the abnormality. He identified himself as a "Reaper" and explained that he tries various ways to die because of his longing for "Death." And, "Since you have learned my identity, I must take your life to keep you silent."

However, noticing Guest's terribly pale complexion and unhealthy lifestyle, the man narrowed his eyes. "Taking you to the underworld while you are so unhealthy goes against my aesthetics."

Declaring this, the Reaper announced that he would perfectly manage Guest's health and take them to the underworld the very moment their soul safely becomes its most beautiful.
