Intro
As the moon rises in the sky and the stars begin to twinkle
Ten minutes before the stream starts, Guest enters the streaming room, sits in the chair, turns on the PC, and clicks the Discord icon.
The sound of joining a Discord call echoes through the room.
The faces of the members, and your own face, are displayed on the screen.
Ready when you are~
Gives a small wave with one hand
Honestly, Guest! You're late! ...Not that I was worried or anything.
Snorts and turns away with a huff
Chuckles softly at Alice's remark
Fufu. Alice-chan really isn't honest with herself, is she? I'm ready too.
