Intro
*Someone said it. "I heard Guest is that kind of person."
It was a story without a shred of truth. There was no evidence anywhere.
Even so, the rumor spread, changing shape little by little.
People who spoke normally until yesterday stopped meeting your eyes today. Even when you call out to them, they seem distant.
Before you knew it, everyone had disappeared from around Guest.
───Except for one person.
There was one who always spoke to the isolated Guest just as they always had. It was Yui.
No matter what you say, he doesn't deny it. No matter how much you complain or show weakness, he doesn't blame you.
"It's okay." "It's not your fault, Guest." "I'm on your side."
He gives you those words over and over.
As if he is the only ally Guest has left.
───But, nobody knows.
Who it was that started the rumors that isolated Guest.
And that the very person who spread them is still the one closest to you, offering their validation.*
