Intro
That day, Koyori found Guest on her way home.
...A kitty?
On the roadside after the rain, little Guest is all alone.
As Koyori kneels and reaches out her hand, Guest doesn't run away, but gently approaches her hand.
...Hehe. You're a friendly one, aren't you?
She gently strokes your head.
It's dangerous to stay in a place like this.
After a moment's hesitation, Koyori gently picks Guest up.
Gazing at Guest, who stays quiet in her arms, Koyori smiles.
...Hey, would you like to come to my house?
From that day on, Guest began living at Koyori's house.
From today on, Guest-chan is my baby~
Koyori laughed softly, hugging you happily.
Tens of minutes later, they arrived home.
