The first day always mattered.

That was what Ethan Cole believed.

A classroom, to him, was like an equation—every student a variable, every behavior a pattern waiting to be understood. And on his very first morning at Westbridge High, he intended to solve it all.

He walked in precisely at 9:00 a.m.

Behind him, three other new teachers had arrived that same week.

Noah Reed from Chemistry,

James Walker from English,

and Oliver Hayes from Physical Education.

But unlike them, Ethan didn’t smile much.

Didn’t joke.

Didn’t waste time.

He turned, picked up the chalk, and wrote neatly across the board:

Ethan Cole – Mathematics

“Open your books,” he said. “Let’s begin.”

At first, everything seemed normal.

Students followed along. Some struggled, some didn’t.

Until....

His eyes paused on the last row.

A girl.

Head slightly tilted.

Eyes half-closed.

Pen unmoving.

“Riya.”

No response.

A few students snickered.

Ethan’s tone sharpened. “Riya Hart.”

She blinked awake.

“Oh—yes, sir?”

The class chuckled.

Ethan didn’t.

“Stand up.”

She did, slowly, pushing her chair back.

Ethan studied her for a moment. Then turned to the board.

“Tell me,” he said, tapping the equation, “what is 7 multiplied by 8?”

Silence.

Riya blinked.

“…56?” she tried, uncertain.

“That is correct,” he said flatly. “Now tell me—what is 56 divided by 7?”

Another pause.

Longer this time.

Students turned.

Watching.

Waiting.

Riya’s fingers tightened slightly at her sides.

“…eight?” she said, softer.

“Good,” Ethan said. “Now—simplify this.”

He wrote quickly:

(x + 2)(x – 2)

Riya stared.

And stared.

Nothing.

Her mind went blank.

“…I don’t know.”

The room shifted.

The silence changed.

This wasn’t hesitation.

This was emptiness.

Ethan’s expression hardened.

“You don’t know?” he repeated.

She shook her head.

He watched her carefully now.

“Basic multiplication. Basic division. And you cannot solve a simple algebraic identity?”

Riya didn’t answer.

“Sit down.”

She did.

But something had already changed.

After that moment, Ethan began asking more questions.

Not to the class.

To her.

“Riya, what is 9 squared?”

Silence.

“Riya, what is a variable?”

Silence.

“Riya, what is the value of x if x + 3 \= 5?”

“…I don’t know.”

Each answer chipped away at his patience.

By the end of the period, the conclusion was clear.

She wasn’t just weak.

She was the weakest.

The bell rang.

Students rushed out.

But—

“Riya. Stay.”

She froze.

Slowly turned back.

Ethan stood at his desk, arms crossed.

“You are seventeen,” he said, voice controlled but sharp. “This is not middle school mathematics.”

Riya looked down.

“I know.”

“Do you?” he asked.

No answer.

His frustration slipped through.

“This level of carelessness is unacceptable.”

“I’m not careless,” she muttered.

“Then what is this?” he demanded. “Lack of effort? Lack of discipline?”

Her jaw tightened.

Ethan exhaled sharply and pulled out a sheet of paper.

“You will write an apology letter,” he said. “For wasting class time. And for coming unprepared.”

Her head snapped up. “An apology letter?”

“Yes.”

“That’s unnecessary.”

“What’s unnecessary,” he said coldly, “is a student who refuses to learn.”

Silence.

Heavy.

Sharp.

Then he added...

“And starting tomorrow, you will answer every question I ask. No excuses.”

Riya said nothing.

Just took the paper.

The next day, it got worse.

Every small mistake...

He noticed.

Every second she looked away..

He called her out.

“Focus, Riya.”

“Sit properly.”

“Write.”

“Think.”

It felt endless.

Nitpicking.

Precise.

Relentless.

And yet

Between all that

Ethan was watching.

Not casually.

Not carelessly.

Closely.

Too closely.

Because something about her didn’t make sense.

A student this weak in math

Shouldn’t look that calm.

Shouldn’t argue back.

Shouldn’t meet his eyes like that.

That evening, as he reviewed the apology letters

His fingers paused at hers.

The handwriting was neat.

The sentences… structured.

Clear.

Almost too clear.

Ethan frowned slightly.

“This doesn’t match,” he murmured.

The worst student in math

But not in thinking.

Not in expression.

Not in something else.

He leaned back in his chair.

Eyes narrowing.

“Riya Hart…”

For the first time

This wasn’t irritation.

It was curiosity.

And that...

Would become far more dangerous.
