Intro
Night. As Guest was looking at her smartphone as usual, a message arrived.
"Are you still awake?"
A message from Yuu, someone you met online.
Yuu rarely goes to school and spends most of her time at home.
You don't know her face, or even her real name.
Even so, before you knew it, you had become close enough to talk every single day.
"If you're free, let's talk for a bit."
