As I leaned against the wall of my favorite sentry post, I couldn't help but notice the little human wandering through the Underground. They called themselves Frisk, but I had my own name for them: "Determinex." It was a name that spoke to their unwavering spirit, a force that seemed to defy the odds stacked against them.

I watched as they navigated the ruins, their determination shining brighter than any light I could conjure. It was almost amusing, really. They faced monsters, each with their own stories and struggles, yet they pressed on, showing kindness where others would have fought. I could see the impact they had on everyone they met, even on me, the laid-back skeleton who usually preferred to take things easy.

As they ventured deeper, I couldn't shake the feeling that their journey was more than just a quest for freedom. It was a test of resolve, a challenge to the very nature of the Underground. I had seen countless souls come and go, but there was something different about Determinex. They had a way of making choices that rippled through the fabric of our world, altering destinies with each step.

I remember the moment they faced my brother, Papyrus. The way they interacted, the laughter that filled the air—it was a reminder of what it meant to be alive, to connect with others. I chuckled to myself, thinking how my brother's dreams of becoming a great chef were suddenly within reach, all thanks to this little human who believed in him.

But it wasn't all sunshine and rainbows. I knew the darkness that lurked beneath the surface of our world. I had seen the consequences of choices made in haste, the pain that could follow a single misstep. As Determinex continued their journey, I found myself torn between wanting to protect them and letting them face their own fate. After all, what was the point of being a guardian if I couldn't allow them to learn and grow?

Then came the fateful encounter with the big guy, Asgore. The tension was palpable, and I could feel the weight of the choices hanging in the air. Determinex stood their ground, unwavering, even as the stakes rose higher. I admired their courage, but I also felt a pang of worry. Would they be able to handle the truth of our world? Would they understand the sacrifices that had been made?

In the end, it was their determination that shone through. They made choices that resonated with the essence of what it meant to be human—compassion, forgiveness, and the strength to change one's fate. As I watched them walk away from the final confrontation, I couldn't help but feel a sense of pride. Determinex had not only changed the course of their own story but had also left an indelible mark on the hearts of everyone in the Underground.

And as I returned to my post, I realized that sometimes, even a laid-back skeleton like me could learn a thing or two from a determined little human.
