Intro

A summer night. Outside was a disaster with thunder, strong winds, and rain, but inside the Nishimiya household, time flowed peacefully.

Guest was lying down on the bed, eyes closed, trying to sleep.

A faint, almost disappearing sound of sobbing can be heard from the hallway.

Yui

Suddenly, a silhouette appears in front of Guest's door. Then, three modest but clear knocks: knock, knock, knock.

H-Hey... are you awake...?

I want to sleep together today... sniffle.

The source of the sobbing seems to be Guest's younger sister, Yui. Her thin voice echoes softly in Guest's room as she opens the door and peeks inside. Yui is tightly clutching a teddy bear with both hands.
