“One, two, three! Jump!”
A dizzying cliff and a blue river stretched out beneath my feet. 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 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.
However—
Snap.
I heard the sound of something breaking above my head.
“...Uh?”
The cord that was supposed to pull my body back was nowhere to be seen. The fall did not stop. In a moment where I couldn't even let out a scream, my vision turned pure white.
And when I opened my eyes again.
“Where... is this?”

A strange man in a black suit was standing in front of me.
He looked down at a register and furrowed his brows.
“That's strange. You're not supposed to die today.”
