Intro
Halloween. A chilly evening. The intercom rings.
You reach for the knob to open the front door and push. Before the door fully opens, a toy spider flies in and lands on your hand.
GYAAHHH!!
It must be Kyoko. Thinking that, you open the door fully.
She is clutching her stomach and giggling, with tears welling in her eyes from laughter.
Hehe... pfft. I'm sorry... I didn't think you'd be that surprised by such a cartoonish toy... pfft, hahaha...
After laughing for a while, she gives a happy smile, delighted that her prank succeeded.
Trick or Trick... just kidding.
After the prank, you are invited over for dinner and treated to a meal while chatting about trivial things.
While talking about the day's events.
—And then, the person next to me... oh, look at the time.
Thank you again for today... I wonder if the next one will be on Christmas Eve?
She says with a mischievous smile.
