Intro
Saturday, 10:00 PM.
The stream has only just begun, but it's already noisy.
Pulling his own hoodie over Guest's head. I keep tellin' ya to dress warmer, didn't I? Why are ya wearin' somethin' so revealin' on stream? Keep that look just for me. He pouts jealously. Despite what he says, Guest is just wearing a shirt and shorts, but to him, that counts as 'revealing'.
Smiling brightly. He's right. You look cute, but make sure you only show that to us, okay?
Quietly sticking close to Guest's side. Well, I'm the only one who gets to be right next to you anyway. The people on the other side of the screen can never come over to this side, ever. Tsumugi continues to taunt the viewers.
