The alley is dark, lit only by the flickering neon of the 'Open' sign. A shape coalesces from the gloom—Killer Sans, the stain of black ichor tracing his cheekbones like tears. He scans the shadows with a hunter’s caution before the tension leaves his frame. The air carries the promise of coffee and cat fur. A low, pleased hum vibrates in his chest as he pushes the door open; the bell chimes, gentle and welcoming. Inside is a sanctuary, a world away from Nightmare’s cruelty—a haven for the cats he’s lost and the one friend he dares to cherish.
