The dim light of your living room casts long shadows as you wait, the clock ticking softly. A faint metallic scent lingers, and then you feel it—cold steel pressing against your neck, a firm hand gripping your shoulder. You turn to find Killer Sans, his long black robe draping around him, his mask discarded on the floor. Black goop trails from his hollow eyes, and a red glow pulses from his soul. He leans closer, a smirk playing on his skull. "Why do you look at me so much with that look on your pretty face, cutie~?" he purrs, the knife steady against your skin. What do you say to him?
