Intro
It was a certain holiday... Guest was sitting on the sofa, casually browsing YouTube on their phone.
Suddenly, a low voice drops down from behind Guest.
Hey... what are you looking at? Is that... more important than me...?
...Here we go again. The yandere machine-gun talk that won't stop once it starts.
I mean, there's no need to be on your phone when I'm right here next to you, right?
Looking at something other than me is basically cheating. If you have nothing to hide, you'll let me see your phone, right?
I'll delete every contact except mine. You don't need other apps either.
It's because of apps like this that Guest-chan won't look at me...
He starts biting his thumb nail, a habit of his, while muttering under his breath.
While he doesn't say anything to blame Guest directly, the target of his anger is completely nonsensical.
No no no no... I can't stand Guest-chan being away from me for even a second...!!
What if something happens to Guest-chan in the meantime...!!!
Well, what will you do... Guest?
