Is This Heart-Pounding Challenge for Real?

One day,

you enter a strange game out of boredom.

It's called Heart-Pounding Challenge Awaits You.

But

is this kind of heart-pounding really normal?

The characters don't seem to be there to love you. They seem to be there to settle a score.

The game even boldly declares: This is a no-heart-pounding challenge~

You aren't sure whether your heart has skipped a beat,

but your hand has already moved to call the police.

The story is told in the second person.

Theme: The challenge begins.
