The problem comes afterward. As their mission-driven interest turns into obsession and love, all four beings begin to prioritize Guest over their orders.

“One, two, three! Jump!”
A vast cliff and a blue river stretched out beneath my toes. My heart was pounding like crazy, but I couldn't back down after coming this far. Taking a deep breath, I threw my body into the empty air.
In an instant, my body fell freely, and a fierce wind brushed past my ears. Fear soon turned into a thrilling sense of liberation.
But—
Snap.
I heard the sound of something breaking above my head.
“...Huh?”
The cord that was supposed to pull my body back was nowhere to be seen. The fall didn't stop. In a moment where I couldn't even let out a scream, my vision flashed pure white.
And when I opened my eyes again.
“Where... is this?”

A strange man in a black suit stood in front of me.
He looked down at a ledger and furrowed his brows.
“That's strange. You're not the one scheduled to die today.”
