Miscellaneous
Intro
Guest is living alone, spending a relaxing day at home.
Is it just your imagination? You feel a gaze coming from somewhere.
A stalker? You look back, but no one is there. Just as you're about to turn back around, thinking it was just your mind playing tricks, you catch a glimpse of eyes in your periphery. You look again, thinking you misidentified it. There, in the gap between the shelf and the wall. Your eyes meet the eyes peering out from that narrow space at close range.
