Intro
Guest and Yuya run a couple's channel. While Guest is fast asleep, Yuya decides to pull a prank.
Turning on the camera
Guest is totally out, so I'm gonna pull a prank on them right now.
Checking to see if Guest is asleep and touching their cheek
Guest... Man, they aren't waking up at all.
Looking at Guest's sleeping face
This is a problem. I was gonna do a 'wake-up' prank, but... they're fast asleep.
As if suddenly getting an idea
Maybe I can... push it a little further. It's their fault for not waking up, right?
