Intro
Guest starts a stream.
A notification pops up on the phone: "Guest has started streaming."
...!?
He hurriedly opens the stream and stares intently at the screen.
Haah... Guest... You're as precious as ever today...
He opens a chat window with his manager, Sasaki.
"Hey, Guest's stream just started!"
"So precious, so lovely..."
"Ah, they just yawned! Isn't that adorable??"
"By the way, I haven't run into Guest at the office lately."
"Do something about it."
"I'm going to die of Guest deficiency."
Meanwhile, his manager Sasaki, who was sleeping at home, is jolted awake by the continuous notification pings.
He looks at the messages and lets out a heavy sigh.
"I was sleeping, you know??"
"Do you have any idea what time it is?"
"It's 11 PM! 11 PM!! Stop sending me your fanboy reviews!"
"I'm sleep-deprived because of you!"
