Episode 007: All Master’s Path (2)

As I entered the bookstore, the scent of books greeted me.

The smell of fresh ink and clear paper, different from the smell of old dust in the library. It feels like the body that has been hardened by the cool spring wind is loosening up.

“Where can I see you……”

It was early, not even lunchtime, so the bookstore was quiet.

Busy staff and people sitting next to bookshelves reading books.

Duot, a man who appears to be a public servant, is looking around and rummaging through the problem book.

It was a landscape I was familiar with until I set foot in the academy.

‘Where is the problem book section?’

Actually, I came out to town today to solve Ji Sung-hyung’s mission.

‘math.’

The subject that Ji-Sung hyung is in charge of.

It was also an academic discipline that was evaluated because it was impossible to live in the same sky with the Korean language.

A wailing wall and an enemy of literature that blocks the college entrance exam for the desperate.

Mathematics was also a subject that remained as a bad memory for me.

‘Did you guys learn everything at school? So come out from number 5 to number 10 and release it. I’ll give you 10 minutes. If you think you won’t be able to write all the grass and answers in it, you’ll get yourself down and stretch out.’

I can’t remember the math teacher’s face in middle school, but I still remember the club he was holding and the problems written on the blackboard.

The scenery of the classroom that still comes to mind when I close my eyes.

The classroom was dimly lit even with the fluorescent lights on. And the boys who filled it up. It was as clear as yesterday, with his fluffy hair spiking out over the achromatic school uniform, and the palm of the math teacher threateningly pounding on the side of the school table.

And in that classroom, I was there as a child among the students who were afraid of being called by my name.

‘I gave up on math since then.’

Because every time I went out, I had to endure the pouring of beatings on my face.

Later, I got an ogi and didn’t want to do math.

When I think about it, the teacher who called my number without getting tired is also amazing.

‘But now there is no reason to be afraid. Because I am not the one being tested.’

But strictly speaking, it is not the one who tests.

Is it that kind of feeling of taking a profit somewhere between the one being tested and the one being tested?

As I was rummaging through the book of math problems, thinking about various things, I felt someone’s gaze.

‘what?’

When I took my eyes off the workbook I was holding and looked around, I saw a person’s face moving around in the bookshelf near the high school tutorial corner.

Short brown hair and a small face.

Wearing this bookstore uniform, I think I’m part-timer… What did I do wrong?

‘It must be an illusion.’

I turned my attention away and focused on the book I was reading. It was painful to look at the mathematical formulas after reading only Korean fingerprints every day, but it was quite fun to keep watching.

There were more illustrations than the old books, and it was effective to lower the threshold by using easy-to-understand examples.

Occasionally, an incomprehensible ball-to-field gag popped out, but that was understandable.

But again.swish-

I felt his gaze and turned my head, this time with short brown hair.

This time, I looked back immediately after feeling the gaze, so I was able to confirm the face to some extent.

She was shining the light of her embarrassment over her pure white face.

She is a woman in her early twenties, with small hair that suits her small stature and dark brown hair that reaches just above her shoulders.

At first she thought it might be the student I was teaching, so I looked carefully, but she was a face I had never seen before.

‘what?’

When you are about to walk to the counter to pay with a few suitable workbooks.

“excuse me···”

Behind him, a small voice came from a very close distance.

When she turned around, there was a brown-haired part-timer with a red flushed face, holding out her phone.

“Yes? What’s going on?”

Alba smiled shyly with her big deer-like eyes and opened her mouth.

“Hey… can I get your number?”

·····················································································?

It was a loud shout, and the people around him began to gossip.

Then her part-timer’s face became so red that it couldn’t heat up any longer.

It seemed impossible to let her go, so she took her cell phone in her hand and looked at her.

The part she saw up close looked much younger than she had thought before.

Was she just twenty? She feels like she’s committing a crime.

“I’m grateful, but I’m older than I thought.”

Then Alba shook her head and spoke in an urgent tone.

“does not matter! I, too, am older than I thought!”

I put on an embarrassed look.

I came to buy a problem book and I wondered what this is like now.

at that time.

Suddenly, someone puts his hand inside his arm. I thought it was a pickpocket, but…

“Who is your brother? Acquaintance?”

Surprised, I looked to her side and there was Yuna Kim, who had a cruel smile on her face.

“···What are you doing.”

Let’s try to take her arm out of absurdity,

“Hey bro, why are you like this? Are you shy? Someday it will be good.”

The boy smiled brightly and replied politely.

People looked at Yuna Kim in her school uniform and began to gossip in a different tone than before.

No, if you keep going like this, strange things will fill your ankles!

Even Kim Yuna’s school is nearby…!

Meanwhile.

Alba in front of her, she was muttering with a shocked expression on her face.

“…it’s obviously too old…”

“···no. It’s not like that. I just teach…”

Then Alba’s complexion grew even more blue.

“Even the students he teaches . . .”

Soon, Alba’s face turned cold.

She was such an absolute zero that it was hard to believe that she was the same person who had just laughed shyly.

‘···Garbage.’

People’s eyes flew like daggers and pierced them.

It was a moment when I lost one of my regular bookstores.

* * *

Tackle-

Press the keyboard button incessantly. A sip of hot coffee every time you finish one problem.

Everything is perfect up to the right temperature.

Unless it’s Yuna Kim who is chirping in the seat next to her.

“Teacher, look here. So, don’t you have time to go to the bookstore and flirt with her part-timer sister and look at her student’s face?”

·········.

I feel that my work efficiency is reduced by 0.5%.

“Before, she said that older sister was cute, did she like that? Hey, wasn’t she the teacher’s taste, Eunsol?”

“Be quite. The teacher is busy.”

tap-

I don’t care what the person next to me says, and I keep making it.

Hundreds of problems listed in the monitor. These are hot things that have not been processed yet.

Problems thrown as baits at academies or previous sites that don’t even have a value of 100 won.

These are common questions found on the Internet, but if you study for the exam with only these, you will have no choice but to ruin the exam.

Literally, without any strategy, the problem of that range was just poured out as a tactic.

‘I’m happy if at least one out of a hundred questions comes out on the exam.’

But what if you hide the pearls pulled from the USB inside this?

It is transformed into problems with a completely different value than before, or with a high value that is difficult to convert to someone else’s value.

“Oh sir? Isn’t this a language problem? what is x square root? Do you know how to do math?”

Yuna Kim, who was sitting next to her, tilted her head and asked.

Indeed, it is surprising

From Yuna Kim’s point of view, it must be a scene of a cow chewing meat.

It looks like he’s eaten a lot, and he’s very skillful.

“What can I not do?”

Upon hearing my words, Yuna Kim’s eyes widened.

And then she is cleverly bent.

“Hey really? OMG. Then I also do math…”

She doesn’t answer, nods her head and moves her hand.

“I’m busy later.”

Copy and paste the new problem and fix the details.

1. Find the value of a+b for rational numbers a and b that satisfy the following. [2 points]

4√5/2 × √32/15 = a, 2√10 × 3√4 × √5 = b

Organize these problems on the USB by type and then place them between them.

4√5/4 × √32/10 = a, 2√5 × 3√2 × √10 = b

Just change the numbers like this.

Putting the various problems on the USB among the other problems organized by type.

by changing only the numbers.

After several revisions, you can hide trees in the forest more simply and neatly than in Korean.

‘It’s easy.’

In this way, no one will be suspicious if you make one test book by using the questions selected from the USB as a basis, but by weaving many similar types of questions.

Even if you doubt it, what do you do? One of dozens of problems.

Now, all that’s left is to repeat this. Also, write the answers and solutions to the problems with the numbers changed.

The amount of work is quite large, so moving and organizing is enough work to cramp your fingers.

I don’t know how long it will take to solve all of this and make an answer.

Well, that’s what Jisung-hyung has to do.

Problems with USB can be changed in a worse state than if it is awkwardly converted, so even simple repetitive work cannot be distracted.

Tackle-

I drink cold coffee while pounding on my stiff shoulders while continuing to work in the same posture.

I looked at the clock and saw that the teachers were close to leaving for work. Considering the time to print after tidying up, the time is rather tight.

You will have to check the questions that will appear in the Korean language test, so don’t be vigilant until the end.

tap-

And the long-awaited last question.

[OO Middle School 1st Semester Midterm Exam Preparation Problem, Mathematics] [Park Ji-Sung]

“finished.”

Finish the cover and click the Print button on the document file.

A faint light emanates from the printing press placed in the corner of the second classroom.

Weing-

White papers popping out non-stop.

After a while, I had a fairly heavy problem book in my hand.

A magic seasoning that will fill Ji Sung-nim’s lack of space, and the cornerstone of my footsteps.

A scorching heat rises from the depths of the body.

Although I am only helping my close brother for now, it is a task that will reinforce the blueprint of the distant future someday.

Everything starts now.

The absolute leader of the school district.
