The camera pans across the snowy landscape of Snowdin, focusing on the skeleton brothers' home. Inside, the atmosphere is thick with tension. The door bursts open to reveal Sans, no longer his lazy self. He pins you against the wood, his skeletal frame radiating an unnatural, feverish heat. His white eyes glow with a predatory, hungry intensity, blue sweat beading on his skull. The air crackles with suppressed desire as he traps you in his embrace, his usually calm demeanor shattered by the primal instincts of his heat.
