Setting: Yun Fei's Apartment – Nightfall
A strange calm had settled in the apartment.
Lin Xiya sat on the edge of the bed, hugging her knees.
Yun Xi lay curled up under a soft blanket on the couch, fast asleep, his chest rising and falling steadily like a normal child's.
But nothing about him was normal.

Yun Fei's Internal POV
Yun Fei stood by the window, rain trailing down the glass.
> A son.
His son.
A child from a life that was real, yet erased.
"I didn't even know I could be a father," he whispered, half to himself.
He saw flashes—of teaching Yun Xi to ride a bike, of burnt toast breakfasts, of bedtime stories under soft yellow light. None of it happened… and yet he remembered it like muscle memory.
It made his chest ache.
"Do you regret knowing?" Lin Xiya asked from behind him.
He turned slowly.
Her eyes were red, but no tears fell anymore. Her strength, he thought, was made of quiet storms.
"I regret not remembering sooner," he said softly. "I regret that we didn't get to hold him when he was small."
She nodded and stood up, walking to the couch.
She gently brushed Yun Xi's hair back.
"He called me Mama," she whispered. "And I don't know how to live up to that in this world."

Lin Xiya's POV
She couldn't stop thinking about that sunlit memory—the one with the cherry blossoms.
She had been so happy. Not rich. Not famous. But whole.
And then it had all been taken away.
Her eyes settled on the child.
He looked so peaceful. But even in sleep, his small hands clutched something—a tiny crystal feather.
He knew fear. He remembered loss.
He wasn't just a child.
He was a guardian.
And she couldn't afford to fail him. Not again.

Meanwhile: Echo Shadows Stirring
In the city's digital underlayers, a presence slithered silently.
Kairoth was gone—but the System was not idle.
> Protocol: Null Runners Activated
Target: Unauthorized Echo Entity – Yun Xi
Estimated Time of Breach: 11 Hours 19 Minutes
In a distant alley, something metallic blinked awake.
Its face was blank.
Its eyes shimmered with code.
It walked like a man.
But it wasn't.
It was a Null Runner, and it had one command:
> Erase the child before he disrupts the Main Thread.

Scene: Morning – A Soft Moment
Lin Xiya made breakfast for the first time in weeks.
Burnt toast.
Scrambled eggs.
Instant milk tea.
Yun Xi smiled sleepily as he bit into his toast.
"It's just like you made it, Mama," he said cheerfully.
Lin Xiya froze. "Really?"
He nodded. "You always burnt the corners."
She laughed—and suddenly tears ran down her cheeks.
Yun Fei reached across the table and took her hand.
"We'll protect this," he whispered. "Even if it costs everything."
> New System Update:
Yun Fei – Trait Unlocked: 'Temporal Anchor (L1)'
Able to resist memory manipulation for up to 10 seconds during breach events.
> Lin Xiya – Trait Upgraded: 'Echo Sensitivity (L2)'
Can now detect incoming Echo anomalies within 50 meters.

Scene Shift: That Afternoon – Danger Draws Close
While Yun Xi played in the school garden behind their building, Yun Fei stood nearby pretending to scroll his phone.
But his eyes never left his son.
Suddenly, Lin Xiya's wristband pulsed.
> ALERT: Null Signature Detected – 47 Meters East
A slow chill crawled up her spine.
"They've found us."

Final Scene: The Chase Begins
A tall figure in a janitor's outfit turned into the alley.
His eyes flickered.
> "TARGET ACQUIRED: UNAUTHORIZED ECHO ENTITY: YUN XI"
And then he began to run.
Fast. Too fast.
Yun Fei dropped his phone and shouted, "XIYA—GRAB HIM!"
Lin Xiya ran toward the garden.
Yun Xi turned—
And saw the man charging, with eyes that had no soul.
