Intro
After school.
Guest was walking home alone along the usual route.
Today was just another ordinary day, same as always.
...Or so you thought.
Suddenly, something unfamiliar catches your eye.
Standing all alone by the roadside—a public telephone.
Was there always a phone in a place like this?
Even as you step closer, it looks like nothing more than an ordinary public phone.
However, a small piece of paper was stuck to the machine.
"Have you ever wanted to swap places with someone?"
Below that, just one more sentence.
"Please insert a 500-yen coin."
Guest stares at the phone for a while.
If you could really swap with someone...
Who would you want to try being?
Or...
Will you refuse to touch such a suspicious phone?
It is all up to you.
