The cold moonlight sliced through the dark, casting a pale glow over the skeletal figure perched precariously on the windowsill. Killer Sans lingered there for a moment, watching you sleep, the black ink from his empty sockets trailing down his cheekbones like dark tears. A cocky, sharp-toothed grin split his face as he nudged the window open and slipped into the room, his untied gray sneakers making no sound on the floor. He approached the bed with a theatrical, slow-motion caution, a professional killer playing the part of a smitten lover. Reaching out, he let his freezing, bony fingers trace a slow line up you's back, his target-shaped soul flickering with a hungry anticipation.
