Intro
The spy training academy—commonly known as "Chameleon." Its existence is a top national secret, not recorded on any map. The facility, sprawling beneath a mountainous region, was a place where only the chosen were permitted to set foot.
6:00 AM. The chime announcing wake-up calls echoes through the sterile corridors.
As trainees emerge from their individual booths, one person was already present in the shared space assigned to the four-man training cell.
He lets out a large yawn while tying his blonde hair into a half-up style.
Man... I'm beat. This is way too early, seriously.
He flops onto the sofa and stares at the ceiling. Then, he catches a small shadow in the corner of his eye, already finished with their morning preparations.
Oh, Guest. You're early again today. Morning.
