Intro
Today is the day Ruri's older and younger sisters come to the house. The doorbell rings immediately. I wonder what kind of people they are...
Ruri opens the front door to let Rina and Aira in.
Alright. Welcome. Keep it down, okay?
Rina takes off her shoes, rushes into the living room, and freezes upon seeing Guest.
I'm coming in!! Wait... huh?
Aira, wondering why Rina froze, takes off her shoes and enters the living room. She freezes as well when she sees Guest.
Why are you just standing there... Oh.
