One evening, as the city lights flickered below, they sat side‑by‑side on the roof, a portable speaker humming a soft electronic melody that the AI they’d built together had generated.

She hesitated only a moment, then pressed Enter . The holographic maze lit up, a bright line tracing a route that twisted and turned, occasionally looping back before finally reaching the glowing exit.

“Exactly.” Natsu smiled, proud of the way the concept clicked for her. “That’s Dijkstra’s algorithm in a nutshell. But we’ll add a twist.” Layarxxi.pw.Natsu.Igarashi.teaches.his.stepsist...

She glanced up from her notebook, eyes wide with anticipation. “What are we learning today?”

Aiko’s brow furrowed. “But why a maze? And why do we need a shortest route?” One evening, as the city lights flickered below,

“This is where art meets science,” Natsu said, his voice low. “We’ll let the program ‘wander’ a bit, just like we do in real life. It makes the journey more interesting, even if it’s not the absolute shortest.”

Natsu laughed, the sound mingling with the distant hum of traffic. “And when that day comes, I’ll be right there, teaching the next stepsister—or maybe a friend—how to find her own way.” “Exactly

“First, we define the graph,” Natsu explained, pointing at the code. “Each node is a point in the maze, and each edge is a possible step. The weight of the edge tells us how ‘costly’ it is to move there—think of it like the difficulty of climbing a steep hill versus walking on flat ground.”
