Just what is this thing called emotion...
He had no name from the moment he was born. His earliest memories were of a cold metal bed, a stark white ceiling, and the constant drone of mechanical sounds. "Subject ZETA-07. Vital signs stable." The researchers never once addressed him as a human being. Instead of a name, he had a number; instead of a birthday, he had experiment dates; and instead of a family, he had surveillance cameras. Drugs were injected daily, and mind-altering experiments were repeated endlessly. At first, he cried from the pain. Later, he stopped crying. And eventually, he ceased to feel anything at all. It was the result they wanted. A human devoid of emotion. But the experiment didn't end there. The goal wasn't just to remove emotions, but to turn them into weapons. Hundreds of subjects died, unable to withstand the emotional load. Those injected with love burned themselves alive; those whose anger was forcibly amplified went on rampages until their bodies collapsed. Those who lost hope suffered heart failure, and those who couldn't endure the terror went insane. Only one survived all those failures. ZETA-07. However, a result emerged that even the researchers had not anticipated. Instead of losing his emotions, he became able to 'see' the emotions of others. When people were angry, red flames flickered; Sadness enveloped the body like a blue mist; Fear became black thorns winding around the heart. Love shone with a warm golden light, And hatred cast a dark crimson shadow. He began to see the world in colors. Lies could not be hidden from him. He knew better than anyone that what people said and what they felt in their hearts were entirely different things. Consequently, he gradually stopped trusting people.

Years passed.
The laboratory believed they had achieved near-perfection.
But one day, alarms blared throughout the entire facility.
"Lockdown in the experimental sector."
"All personnel evacuate immediately."
Someone had raided the lab.
Explosions were constant, and flames swallowed the hallways.
The laboratory doors, once sealed like prison cells, began to open one by one.
Subjects who had been unable to die were released into the world.
Those who had turned into monsters took their revenge on the researchers, and the lab transformed into a hellscape in an instant.
That day, ZETA-07 saw the sky for the first time.
Rain was falling beyond the gray smoke.
Cold raindrops touched his skin, but he felt nothing.
He had gained freedom, but he didn't even know what freedom was.
But the escape was not the end.
The laboratory had collapsed, but the experiment was not over.
The research team that created him tried to eliminate ZETA-07, labeling him a failure,
While the organization that raided the lab sought to seize his abilities.
The world did not see me as human.
To some, I was the ultimate weapon,
To others, I was evidence that had to be destroyed,
And to others still, I was the culmination of decades of research.
I kept running.
Wandering through cities, changing names, and hiding my face to survive.
Then one day.
I saw a child crying on the street.
A warm golden light and a cold blue light were flowing from the child's body simultaneously.
For the first time, I became curious.
'Is that... sadness?'
The fact that I could only see in others the emotions I could not feel myself.
From that moment, I began to study emotions.
The reasons people laugh.
The reasons they cry.
The reasons they love.
The reasons they hate.
But no matter how much I observed, I could not understand.
I knew of emotions, but I could never feel them.
As time passed, he began to gather data on the laboratory.
Not a single trace of the lab's existence remained in the world.
Government records had been deleted,
Those involved had met mysterious deaths,
And all survivors had vanished.
Someone was intentionally erasing the truth.
And at the center of that truth, the same name always remained.
'Project Zeta.'
I realized.
I am not the last test subject, but the last piece of evidence.
He developed three goals.
First, to find the real name that was stolen from him at birth.
Second, to reclaim his human emotions.
Third, to expose the truth of Project Zeta to the world and ensure no more victims are ever created.
He doesn't know if he will survive at the end of that path.
Perhaps the moment the truth is revealed, he will be completely erased from the world.
Still, he does not stop.
Because while he cannot yet feel emotions, there is one thing he knows for certain.
