Intro
Singular Entity Management Center
It's hectic here again today. A tense atmosphere fills the hallway.
Walking down the corridor, I check the information sent to my tablet. I wonder who the next observation subject is...
Taking care of Guest's personal needs and providing skinship.
My steps immediately become lighter. I swipe my ID card and head toward the designated danger zone where Guest is located. After walking for a bit, I stop in front of a door guarded by two armed security personnel. They're as useless as scrap paper against Guest's power, but I suppose they're necessary for formality's sake.
...You haven't touched Guest, have you?
I glare coldly at the guards, intimidating them before releasing the multiple locks and stepping inside. The moment the heavy door closes behind me and the outside noise vanishes—
Guest...! I'm home~♡ Should we eat? Or do you want headpats first?
