The battlefield had gone silent.
Dust drifted slowly across broken stone. The air still carried the metallic scent of blood and scorched pollution, but the tension that had once choked the space was gone.
Marco stood a short distance from One.
Watching him.
For a brief moment, neither of them spoke.
Then—
Marco smiled.
Not the faint, controlled smirk he sometimes wore.
Not the cold expression he used when calculating.
A genuine smile.
The first one since their earliest days together.
It was small.
But real.
One froze slightly.
His mind had still been clouded with confusion about the battle, about the strange state he had fallen into — about the voice that pulled him back.
But that smile interrupted everything.
It caught him off guard.
There was something inside it he couldn't understand.
Relief.
Encouragement.
Pride.
Why?
He had only done what he was supposed to do.
Why did Marco look relieved?
Why did he look… proud?
A strange sensation formed faintly in One's chest.
It wasn't discomfort.
It wasn't fear.
It wasn't anger.
It was unfamiliar.
And he didn't have the words for it.
He quickly looked away.
His armor, once sturdy and dependable, was now a ruined shell.
It hung off him in cracked, corroded fragments — polluted energy having eaten into its structure during the fight.
He began removing it slowly.
Metal pieces fell to the ground with dull, heavy sounds.
Marco stepped closer, positioning himself slightly to the side — instinctively guarding him while he stripped away the damaged plating.
One bent down and lifted the head of the slain abomination.
The weight was heavy.
Solid.
Real.
Proof.
He glanced once more at the broken armor lying at his feet.
It had been with him for so long.
Through patrols. Through ambushes. Through growth.
He stared at it with a strange expression.
Marco noticed.
He followed One's gaze to the ruined armor.
"I'll repair it," Marco said calmly.
One looked up.
"And upgrade it."
There was no hesitation in his voice.
"A reward," Marco added, "for winning."
One blinked slowly.
A reward.
He had not expected that.
Marco bent down, lifting the damaged armor with ease, slinging it over his shoulder as though it weighed nothing.
"Let's go."
He turned and began walking toward the mechanical vehicle in the distance.
One followed quietly.
Inside the vehicle, Steven remained alert.
When he saw Marco approaching while carrying a partially destroyed, corroded armor, his expression tightened instantly.
He stepped forward, scanning the surrounding area quickly.
Then he saw One walking behind Marco.
Alive.
Steven exhaled deeply, tension draining from his shoulders.
"Almost three hours," Steven muttered, glancing at the time display.
He then looked at Marco.
"There's something else you should know."
As they approached the vehicle, Steven explained everything.
The mutant father. The injured daughter. The agreement One had made. The transaction involving the abomination heads.
He detailed the entire situation from the moment Marco left.
Marco listened in silence.
When Steven finished, Marco's gaze shifted backward.
Toward One.
Carefully.
Scrutinizing him.
He studied One's face — that usual indifferent expression that revealed almost nothing.
Why risk your life for a stranger?
The question echoed in his mind.
It wasn't strategic.
It wasn't necessary.
It wasn't ordered.
Marco searched for reasoning.
Compassion? Curiosity? Impulse? Hidden calculation?
He found nothing.
And that irritated him more than he expected.
He did not understand what moved inside One's mind anymore.
That blank, controlled expression bothered him.
After a moment, he exhaled softly.
Frustration faded into acceptance.
They resumed walking in silence.
Upon reaching the mechanical vehicle, Marco placed the broken armor carefully inside.
He turned toward One.
"Change your clothes," he said. "Then follow Steven back to the Sanctuary."
One paused.
Marco continued:
"The girl is your responsibility now."
His gaze hardened slightly — not in anger, but in emphasis.
"You risked your life for her. That decision carries weight."
One nodded slowly.
Relief washed over him.
He had expected a reprimand.
A lecture.
Anger.
Instead—
He had received a smile. A reward. Responsibility.
He realized now that most of his fear had been self-created.
He had overthought everything.
Quietly, he stepped inside the vehicle's inner compartment.
He wiped away blood, sweat, and grime with rough cloths stored along the interior wall. The scent of iron lingered faintly as he cleaned himself.
The water was cold.
But grounding.
He changed into fresh clothing.
His body still felt strained, but lighter now.
When he stepped back out, he picked up the severed abomination heads.
Heavy trophies.
There was a faint trace of pride within him now.
Small.
But real.
He walked toward Steven.
Ready.
Not just to complete a transaction—
But to fulfill a responsibility he had chosen himself.
And though his expression remained calm—
Something inside him had shifted.
Slightly.
Irreversibly.
