"We are flawless. But that does not mean we've never almost made mistakes."
The morning light on the Evergrace estate wasn't sunlight—it was a carefully synthesized imitation tuned to the precise warmth Yui once associated with Ren's shoulder when they were seven.
They sat in the breakfast atrium as usual, a floating table suspended above a crystalline lake that hummed softly to match their neural rhythms. A hundred creatures from extinct Earth species wandered beneath the transparent floor—docile, ornamental, oblivious.
Ren drank silence in sips.
Yui was painting the air with her finger, programming the patterns into the sky.
And then, she said it.
"I want to make a place for our mistakes."
Ren didn't look up.
"We don't make mistakes."
Yui smiled softly. "Not anymore."
She let her fingertip trail into a slow spiral, leaving behind a cloud of violet vapor, then added:
"But we came close. Sometimes. Back then."
Ren didn't reply. But he had paused mid-sip.
He hated hesitation.
Yui's voice was gentler now. "I want to remember the moments we almost did the wrong thing. Or doubted. Or felt something unapproved."
Ren slowly set his glass down and turned to her.
His gaze was even. Cool.
And then he said, "Fine."
Section I: Blueprint of a Graveyard
They designed it in silence. No verbal exchanges. Their minds folded into each other's across the neural bridge, speaking in images and weights.
Not a vault. Not a monument. A garden.
Something alive.
Something rooted in time, in personal memory—not absolute perfection.
It would exist in a collapsed corner of their domain: a pocket dimension just outside their estate's central lattice. Suspended in its own frame of timelessness. Outside entropy.
Time would not flow there. But memory would.
Yui named it immediately: "The Error Garden."
Ren raised no objection.
They seeded the soil with crystal-dust mined from failed realities—collapsed simulations, deleted dreams, corrupt echo timelines. The very ash of "almosts."
Then, they began to plant.
Section II: The First Petal
The first tree took hours to design. They grew it not from wood or data, but from fragments of thought that neither of them spoke of anymore.
Ren supplied the seed.
It was the moment he nearly questioned Yui's judgment during their seventh assassination—when she chose a nonlethal method and smiled after.
He had wanted it to be clean. Efficient. Final.
She had wanted it to mean something.
He'd almost said so. Almost doubted her.
Yui took that moment, held it in her palm, and grew it into a tree with fractal limbs and leaves that shimmered with shifting hesitation.
They called it the Fracture Tree.
When Ren touched it, it played the sound of his own breath catching—too quietly for her to notice at the time.
But now, she heard it.
She smiled and touched the branch.
Section III: Flowers of Almost
Dozens of vines spiraled along the garden's trellises, each grown from subtler things.
A moment Yui wanted to speak but didn't.
A glance Ren misread for a second too long.
A breath held after a dream where Ren didn't exist.
A file Yui never showed him. A letter. A pulse.
Each was documented, archived, encrypted into growing flora that only responded to their combined presence.
When both twins were present, the garden bloomed.
When either came alone, it dimmed.
And when anyone else approached?
It screamed.
Section IV: Visitors That Never Enter
The Estate AI, curious, requested to be allowed inside.
Denied.
The planetary sub-AIs whispered suggestions.
Denied.
Even their most loyal clone-servants—a few of the females personally cultivated by Yui—once requested permission to view a "petal."
Yui smiled gently and said, "You wouldn't understand."
Ren simply said, "No."
The Garden remained theirs.
Only theirs.
Not even the Heaven Engine had direct access.
This was a graveyard for possibilities—ones so fragile they could only survive in stillness.
Section V: Mistake #0001
At the very center of the garden, on a raised marble platform, stood a suspended prism.
Inside spun a slow-motion echo.
Yui's hand, reaching for Ren's, just a second too late.
A moment extracted from a corrupted simulation they'd once deleted—a "what if" timeline where a solar war distracted Ren and Yui lost sight of each other for four hours.
It was never real.
But the code had recorded her hesitation. Her panic. The hollowness that bloomed inside her.
She had screamed once in that dream.
Ren had never heard it.
Until now.
Section VI: The Thorn Garden
Some errors were not whispers. Some were louder.
The Thorn Garden bloomed red and violet and black. It held:
The time Yui almost let a cloned girl touch Ren's shoulder out of pity.
The experiment that gave a temporary AI a heartbeat—and Ren's favor.
A neural delay where Ren's mind had been slowed for repairs, and Yui spent three seconds alone.
Those three seconds had become a wall of thorns.
Yui had built it herself.
She didn't cry often.
But she sat inside it for an hour without speaking.
Ren waited outside the wall until she emerged.
She smiled like nothing happened.
He didn't ask.
She didn't tell.
But the thorns remain.
Section VII: What Yui Buried
There was one thing in the garden Ren did not know.
One buried memory.
Not an error, but a possibility so dangerous she had hidden it beneath the roots of the Fracture Tree.
She had once considered… what would happen if Ren truly loved someone else.
Not physically. Emotionally. Intellectually. Spiritually.
She had simulated it for two seconds.
Watched it.
Felt it.
And then purged the simulation.
But not the echo.
That echo—her grief, her rage, her confusion—now rested at the deepest part of the Error Garden.
Wrapped in silence.
Wrapped in control.
Because even perfection had shadows.
And even love, when absolute, left fear behind like pollen.
Section VIII: Ren's Reflection
They visited the Garden again that evening.
This time, Ren arrived first.
He stood before the wall of failed paradox equations—lines of math he had once considered that would allow time to move backward.
Each failure was recorded here.
Not because they mattered.
But because they reminded him of one thing:
That not even he could rewrite what hadn't happened.
He'd once wondered what life would be like if he'd been born without her.
But he couldn't imagine it.
He stared at one cracked timeline and muttered, "You're not real."
The timeline glowed.
Faintly.
Just enough to make him wonder.
Then Yui arrived, barefoot, smiling like sunlight.
And the glow vanished.
Section IX: Closing Ritual
Before leaving the garden, they always performed the same ritual.
They stood beneath the Fracture Tree.
Held hands.
Closed their eyes.
Let the garden breathe.
Let the past whisper.
Then Yui said, as she always did:
"None of them ever happened."
And Ren replied, "And never will."
Section X: Why They Built It
Not out of guilt.
Not regret.
But preservation.
Even gods need archives.
Even perfection needs context.
And in this garden—where nothing grew unless remembered—they were reminded not of their power…
…but of the exact things they would never allow to happen.
Yui whispered into the soil before they departed:
"Even my fears belong to you."
Ren kissed her hand and didn't ask what she meant.
Because he already knew.
