One crisp autumn afternoon, while wandering through the fourth district of Nishioka, Saki stumbled upon a quaint little café she had never seen before. The sign above the door read "Paco Paco Mama," and the aroma of freshly brewed coffee and baked goods wafted out, enticing her to enter. The café was cozy, with a fireplace crackling in the corner and paintings adorning the walls. Among them, one piece caught her eye—a beautiful landscape with numbers and letters scattered across it: "112610 248."
