Chapter 4: The Third Session (And the Problem With Patterns)
By Friday, Xie Yu had developed a theory.
It was a bad theory.
But it was a theory.
At 8:50 a.m., he stood in the kitchen area, staring at a cutting board like it had personally challenged him to a duel.
On it sat an apple.
A very normal apple.
"This," he said, holding the knife with the cautious determination of a man who had never voluntarily done this before in his life, "is a simple, everyday activity."
[Host is holding the knife incorrectly.]
"I am not."
[Host is holding the knife like a weapon.]
"…I am establishing dominance."
[Over the apple.]
"Yes."
A pause.
[The apple is not resisting.]
"…That's because it knows better."
Ten minutes later, the apple had been successfully transformed into something vaguely resembling slices.
They were uneven.
Visually questionable.
But technically edible.
Xie Yu arranged them on a plate.
Stared at it.
Adjusted one slice.
Then another.
"…This looks intentional," he decided.
[It does not.]
"It does if you don't think about it too hard."
He picked up the plate and walked to the living area, placing it carefully on the coffee table.
Today's setup included:
Textbook (pre-opened).
Notebook.
Two pens.
Water.
Fruit (hand-cut, emotionally significant).
He stepped back.
Surveyed the scene.
Nodded once.
"Balanced," he said.
[Host is overthinking.]
"I am optimizing."
8:59.
A knock.
Xie Yu didn't move immediately this time.
Three seconds.
Measured.
Controlled.
"Come in."
The door opened.
Shen Cixi stepped inside.
Same time. Same rhythm. Same quiet presence that seemed to settle into the room without asking permission.
She closed the door.
Looked at him—
Then, as expected, her gaze shifted.
To the table.
Notebook. Pens. Water.
And—
The fruit.
Her eyes paused.
Longer than last time.
Just slightly.
Then she looked back at him.
"…You brought it back," she said.
"Don't misunderstand," Xie Yu replied immediately. "It's just there."
A beat.
"…Just there," she repeated.
"Yes."
"It wasn't there on Wednesday."
"I didn't feel like it on Wednesday."
"…And today you do."
"Yes."
A pause.
Shen Cixi held his gaze for a moment longer.
Then—
"…Sit," she said.
Xie Yu sat.
Progress.
She took her seat across from him, opened the notebook, and flipped to a fresh page.
"Today we'll cover derivatives."
Xie Yu's soul left his body briefly, then returned out of obligation.
"…That sounds unnecessary."
"It's not."
"It sounds complicated."
"It is."
"…We could not do that."
"We will."
A pause.
Xie Yu leaned back slightly.
"…You've already decided."
"Yes."
"…You always do that."
"Yes."
"…That's not collaborative."
"It's efficient."
"…You really like that word."
"It's accurate."
And just like that—
They started.
—
If the previous sessions had been structured—
This one was… sharper.
Faster transitions.
Less explanation.
More expectation.
Shen Cixi didn't just teach.
She anticipated.
Every time Xie Yu hesitated, she adjusted the next question.
Every time he answered correctly, the difficulty increased.
Not randomly.
Not gradually.
Precisely.
Like she was mapping something.
"…Again," she said, tapping the page.
Xie Yu frowned.
"That step doesn't—" he stopped. Looked closer. "…No, wait."
He recalculated.
Adjusted.
"…It works," he said slowly.
"Yes."
A pause.
"…You expected me to get that wrong."
"Yes."
"…But I didn't."
"No."
"…So you changed the next question."
"Yes."
Xie Yu looked up at her.
"You're adapting in real time."
"Yes."
"…That's annoying."
"It's effective."
"…Stop saying that."
"No."
A brief silence.
Then—
"…You're enjoying this," he said again.
This time, Shen Cixi didn't answer immediately.
She looked at him.
Longer than usual.
Then—
"…No," she said.
Still unconvincing.
Xie Yu narrowed his eyes.
But before he could push further—
"Focus," she said, tapping the notebook again.
And just like that, control shifted back.
—
An hour in—
Xie Yu reached for the water.
Paused.
Then, without thinking—
He reached for the fruit instead.
Took a slice.
Bit into it.
It was—
"…This is uneven," he said.
"Yes."
He froze.
Slowly looked up.
Shen Cixi was watching him.
Not the notebook.
Not the problem.
Him.
"…You noticed," he said.
"Yes."
"…It's still edible."
"Yes."
"…That wasn't the point."
"No."
A pause.
Xie Yu held the slice of apple in his hand.
"…Then what was."
Shen Cixi didn't answer.
She just looked at him.
Then, after a moment—
She reached out.
Took a slice from the plate.
The same one.
The uneven one.
Held it for a second—
Then ate it.
Calmly.
Without comment.
Xie Yu stared at her.
"…That was unnecessary."
"Yes."
"…You could've taken a normal piece."
"Yes."
"…But you didn't."
"No."
A pause.
"…Why."
Another pause.
This one longer.
Then—
"It's fine," she said.
And that was it.
No explanation.
No elaboration.
Just—
It's fine.
Xie Yu looked at the plate.
At the uneven slices.
Then back at her.
Something about that answer—
Didn't sit right.
Didn't fit neatly into anything he understood.
"…You're strange," he said.
"Yes."
"…That wasn't a compliment."
"I know."
And somehow—
That didn't bother her at all.
—
By the end of the second hour—
The notebook was filled.
The pace hadn't slowed once.
And Xie Yu—
Was tired.
Not physically.
Mentally.
Like he had been… chased.
Not aggressively.
Not forcefully.
Just—
Relentlessly.
Shen Cixi closed the notebook.
"That's enough."
Xie Yu exhaled, leaning back.
"…You increased it again."
"Yes."
"You didn't warn me."
"No."
"That's still unfair."
"It's still effective."
"…I'm starting to hate that word."
"That's inefficient."
"…Stop."
"No."
She began packing her bag.
Same movements.
Same precision.
Xie Yu watched her.
Again.
That pattern.
Always the same.
Arrival.
Control.
Adjustment.
Departure.
Except—
Not quite the same.
There were… differences.
Small ones.
The pause at the fruit.
The choice of slice.
The way she had watched him—
Not just as a student.
But as—
Something else.
"…You're doing this on purpose," he said suddenly.
She paused.
"…Doing what."
"This," he gestured vaguely. "All of it."
A beat.
Then—
"Yes," she said.
No hesitation.
No denial.
Just like before.
Xie Yu frowned.
"…You're very honest about that."
"Yes."
"…That's suspicious."
"It's efficient."
"…I'm going to ban that word."
"No."
A pause.
Then she zipped her bag closed and stood.
Xie Yu stood too.
They faced each other across the table.
For a moment—
Neither moved.
Then Shen Cixi reached out—
—not for the candy this time—
—but for the fruit.
She picked up another slice.
Not random.
Not distant.
The one next to the one she had taken before.
"…For the lesson," she said.
Xie Yu blinked.
"…You already took one."
"That was during."
"This is after."
"…There's a difference."
"Yes."
"…What difference."
She looked at him.
For a moment—
Just a moment—
Something in her expression shifted.
Not visible enough to name.
But—
There.
Then—
"You'll figure it out," she said.
And she turned.
Walked to the door.
Paused.
"…Review," she added. "I'll test you."
"…You always test me."
"Yes."
"…That's stressful."
"It's effective."
"…I'm banning it."
"No."
And then she left.
The door clicked shut.
—
Silence.
Xie Yu stood there.
Looking at the table.
At the fruit.
At the notebook.
At the space she had just occupied.
"…System," he said slowly.
[Yes, Host?]
"…She's definitely weird."
[That remains a subjective assessment.]
"She ate the uneven slice."
[Correct.]
"On purpose."
[Likely.]
"She adapts everything."
[Correct.]
"She—" he paused. "—watches too much."
A beat.
[Observation is consistent with her academic profile.]
"…That's not what I mean."
The system, wisely, did not ask for clarification.
Xie Yu sat down slowly.
Looked at the notebook.
Then, after a moment—
He reached for the fruit again.
Took a slice.
The one she hadn't taken.
"…You'll figure it out," he muttered.
A pause.
"…That's a threat."
[Unconfirmed.]
"…It feels like one."
He ate the fruit anyway.
—
Downstairs—
The elevator doors closed.
Shen Cixi stood inside, alone.
Her reflection stared back at her from all sides.
In her hand—
Another slice of apple.
Uneven.
Carefully chosen.
She looked at it for a long moment.
Then—
She ate it.
Slowly.
Deliberately.
Like confirming something.
Her fingers tightened slightly around the empty space where it had been.
"…Three," she murmured.
The elevator descended.
And the pattern—
Was no longer just a pattern.
