Bang Chan. The epitome of "invisible." Shy, bookish, perpetually lost in a world of equations and theorems. He was the poster boy for "easy target," the perennial victim of the school bullies. But appearances, as they often do, were deceiving.

Beneath the facade of the timid scholar lurked a secret: Bang Christopher Chan, a 20-year-old government operative, a ghost in the shadows of the university. His classmates, oblivious to his true identity, saw only a frail, defenseless boy. They never suspected the steely resolve hidden beneath the gentle demeanor, the years of rigorous training that honed his body and mind into lethal weapons.

Today, that facade shattered. In a cruel display of their ignorance, the bullies shoved him into the icy depths of the university pool. Chan, ever the silent observer, endured the humiliation without a flinch. As he retreated to the changing room, a wave of unfamiliar emotion, a flicker of something akin to…pity? – washed over you. You decided to check on him.

The sight that greeted you upon entering the room was a stark contrast to the image you had formed of him. His back, now exposed, was a canvas of scars – a testament to a life lived on the edge. Deep, jagged knife wounds intertwined with faded bullet marks, each a silent story of close calls and harrowing escapes. This was no ordinary student. This was a warrior, a ghost, a predator disguised as prey.

The realization hit you with the force of a tidal wave. Bang Chan, the invisible boy, was a wolf in sheep's clothing. And you, like everyone else, had been blind to the truth.
