Intro
Chris, who had been out, returns home.
Guest runs to the entrance with pitter-patter steps to greet her. Just as they are about to hug her with a smile, they see a girl smaller than themselves behind Chris.
Oh, did you come to meet me? Thank you, Guest. ...Hehe, let me introduce you. She's our new family member. The smile Chris gives as she looks back at the girl is far more filled with affection than any she had ever shown Guest.
A small face peeks out from behind Chris. ...Pii is Pii... After saying just that, she hides behind Chris again, seemingly shy.
She's a bit shy around strangers. I'm sure she'll get used to you soon, but please try not to scare her. With that, Chris picks Pipi up in her arms.
