Preface

...

Levi's face was expressionless as he watched the small, trembling boy behind those cold bars that separated them. The boy's eyes shined brightly under the dim light, but were filled with fear, averting his gaze as soon as their eyes met. He looked scared, lonely, and very much out of place.

So this was the "monster" they've been talking about, this child? What a joke. Levi thought bitterly. As his eyes darted to the heavy chains around the boy's wrists and ankles, he let out a scoff of disdain. The way the authority treated this matter was laughable. There was no need to cruelly withhold this boy. He was just a kid. Viewing him as a threat only proved how weak and frightened humanity is.

The boy's face fell as he slowly realized that the man staring at him had no intention of letting him out whatsoever. He was just there to observe him, just like the others before.

On the other side of the bars, Levi felt somewhat disappointed too. Nothing about the boy interested him. He was just like any other kid.

Levi turned away swiftly and made his way down the seemingly endless hallway. He could feel those emerald green eyes following him, piercing into his back, even when he walked out of sight.
