Chapter 5: The Fourth Session (And the First Wrong Answer)
By Sunday, Xie Yu had made a decision.
He was going to lose.
Not completely.
Not obviously.
Just enough.
Because there was a pattern.
And patterns—he was beginning to realize—were dangerous when only one person in the room understood them.
At 8:55 a.m., he sat on the sofa, already in position, notebook open, pen in hand.
The setup today was… controlled.
Textbook.
Notebook.
Two pens.
Water.
Fruit.
Store-bought this time.
Perfectly cut.
Symmetrical.
Utterly devoid of personality.
Xie Yu stared at the plate.
"…This feels safer," he said.
[Host is attempting strategic incompetence.]
"I am attempting strategic balance."
[Host intends to make mistakes.]
"I intend to regulate expectations."
[Host is overthinking.]
"Yes."
A knock.
9:00 a.m.
"Come in."
The door opened.
Shen Cixi stepped in.
Same as always.
But not the same.
Her gaze moved—
To the table.
Paused.
Notebook. Pens. Water.
Fruit.
Perfect fruit.
Her eyes rested there.
One second.
Two.
Then she looked at him.
"…You changed it," she said.
"Don't misunderstand," Xie Yu replied automatically. "It's just fruit."
"…Just fruit," she repeated.
"Yes."
"…Not cut by you."
A beat.
"…No."
"How do you know," he countered.
"It's even," she said.
A pause.
"…That's not proof."
"It is."
"…It's circumstantial."
"It's correct."
"…You're annoying."
"Yes."
"…Sit," she added.
Xie Yu sat.
He had already been sitting.
This was becoming symbolic.
—
"Derivatives," she said, opening the notebook.
"Again?" he frowned.
"Yes."
"…We already did this."
"Not enough."
"…Define 'enough.'"
"When you stop making mistakes."
A pause.
Xie Yu leaned back slightly.
"…That sounds subjective."
"It's measurable."
"…By you."
"Yes."
"…That's biased."
"It's accurate."
"…You're impossible."
"Yes."
And just like that—
They began.
—
The first question—
Xie Yu answered correctly.
The second—
Correct.
The third—
He hesitated.
Just slightly.
Then—
He gave the wrong answer.
Not wildly wrong.
Not obviously careless.
Just—
Off.
Subtly.
Plausibly.
Shen Cixi didn't respond immediately.
She looked at the notebook.
Then at him.
Then back at the notebook.
"…Explain your reasoning," she said.
Xie Yu did.
Carefully.
He constructed the mistake.
Built it step by step.
Made it believable.
Made it—
Convincing.
When he finished—
Silence.
Shen Cixi stared at the page.
Then—
She picked up the pen.
Drew a small circle around the error.
Tapped it once.
"…This is wrong," she said.
"I know," Xie Yu replied easily.
A pause.
Her hand stilled.
"…You know."
"Yes."
"…And you wrote it anyway."
"Yes."
A longer pause.
Then—
"Why."
Xie Yu leaned back, expression deliberately indifferent.
"…I felt like it."
Silence.
The air shifted.
Not visibly.
Not dramatically.
But—
It changed.
Shen Cixi looked at him.
Really looked at him.
For the first time—
There was no immediate follow-up question.
No adjustment.
No smooth continuation.
Just—
Stillness.
"…Don't do that," she said.
Her voice was calm.
But—
Different.
Xie Yu blinked.
"…Do what."
"Answer incorrectly on purpose."
A pause.
"…You can tell."
"Yes."
"…That's inconvenient."
"It's obvious."
"…Not to most people."
"I'm not most people."
A beat.
Xie Yu tilted his head slightly.
Studying her.
"…Why does it matter."
Another pause.
This one—
Longer.
Then—
"It wastes time," she said.
Flat.
Immediate.
Controlled.
Xie Yu watched her.
"…That's not the real reason."
"Yes, it is."
"No," he said quietly. "It's not."
Silence.
For a moment—
Something flickered.
Gone almost immediately.
But not fast enough.
"…Focus," she said, tapping the notebook again.
But the rhythm—
Was off.
Just slightly.
—
The rest of the session continued.
But not the same way.
Shen Cixi still taught.
Still adjusted.
Still tested.
But—
There was something tighter in her movements.
More precise.
Less margin.
Like she was correcting for something.
Or—
Containing something.
Xie Yu didn't make the same mistake again.
Not because he couldn't.
But because—
He didn't want to see that shift again.
—
An hour later—
He reached for the fruit.
Paused.
Then deliberately—
Took a perfect slice.
A symmetrical one.
Bit into it.
"…This is efficient," he said.
Shen Cixi didn't respond.
Her gaze flicked to the plate.
Then to his hand.
Then back to the notebook.
"…Continue," she said.
—
At the end of the second hour—
The notebook closed.
"That's enough."
Xie Yu leaned back.
"…You're quieter today."
"No."
"…You are."
"I'm not."
"…You hesitated earlier."
"I didn't."
"…You did."
A pause.
Then—
"You're talking more," she said.
"…That's deflection."
"It's observation."
"…You're avoiding the question."
"I'm redirecting."
"…Same thing."
"No."
A brief silence.
Xie Yu exhaled softly.
"…You didn't like that I got it wrong on purpose."
"It was inefficient."
"…You keep saying that."
"Because it's correct."
"…But that wasn't why."
No response.
Xie Yu watched her.
Carefully.
"…You don't like losing control," he said.
Stillness.
Absolute.
For half a second—
Everything stopped.
Then—
"I don't lose control," Shen Cixi said.
Her voice was even.
Perfectly even.
Too even.
Xie Yu held her gaze.
"…Right."
—
She packed her bag.
Movements precise.
Exact.
No wasted motion.
But—
Slightly faster than usual.
Xie Yu noticed.
He didn't comment.
—
She stood.
He stood.
They faced each other.
The table between them.
The fruit—
Untouched now.
For a moment—
Nothing happened.
Then—
Shen Cixi reached out.
Took a slice.
Not random.
Not symmetrical.
The one he had almost taken earlier.
"…For the lesson," she said.
Xie Yu watched her.
"…You skipped the perfect ones."
"Yes."
"…On purpose."
"Yes."
"…Why."
A pause.
Then—
"It's fine," she said.
Again.
The same words.
The same tone.
But—
Not the same meaning.
Xie Yu frowned slightly.
"…You keep saying that."
"Yes."
"…It doesn't explain anything."
"It does."
"…It doesn't."
A beat.
Then—
"You'll understand," she said.
And something about that—
Was different from last time.
Not a suggestion.
Not quite a promise.
Closer to—
A certainty.
—
She turned.
Walked to the door.
Paused.
"…Don't do it again," she said.
Without turning.
"…Do what."
"Answer wrong on purpose."
A pause.
"…Or what."
Silence.
Then—
"I'll correct it," she said.
And she left.
The door closed.
—
Xie Yu stood there.
Still.
Looking at the space she had occupied.
"…System," he said slowly.
[Yes, Host?]
"…Define 'correct it.'"
[Insufficient data.]
"…That didn't sound like studying."
[Statement unclear.]
"…She noticed immediately."
[Correct.]
"She didn't like it."
[She stated it was inefficient.]
"…That's not the same thing."
A beat.
The system did not respond.
Xie Yu looked at the table.
At the fruit.
At the missing slice.
Then—
Slowly—
He sat down.
Picked up the pen.
Looked at the page where he had made the mistake.
Then—
Corrected it.
"…I'll correct it," he repeated quietly.
A pause.
"…That's not a threat."
[Unconfirmed.]
"…It is."
—
In the elevator—
Shen Cixi stood alone.
Her hand rested lightly against her bag.
Inside—
A slice of fruit.
Uneven.
Chosen.
Her fingers pressed against it slightly.
Not enough to break it.
Just—
Enough to feel it.
Her reflection stared back at her.
Calm.
Composed.
Unchanged.
But her eyes—
"…Don't do that," she murmured.
Soft.
Quiet.
Not directed at him.
Not entirely.
The elevator descended.
And somewhere between control and correction—
Something had shifted.
Not broken.
Not yet.
But—
Adjusted.
And unlike the equations in Xie Yu's notebook—
This was not something that could be solved cleanly.
