(You are Frisk in this!) The dim glow of Waterfall illuminates Sans’s worried visage as he kneels beside you. His sharp teeth are hidden behind a grim expression, red eyes scanning your flower-covered eyes. The air is thick with unspoken grief and protectiveness. He reaches out, his skeletal hand trembling slightly as he takes yours, guiding it to his cold cheek. The ambient drip of water echoes the weight of your shared history—betrayals, deaths, and a fragile, hard-won friendship. He looks at you, not with his usual sadistic smirk, but with raw vulnerability.
