I Will Not Live as a Genius

27. Hanon Set

on the way home from school.

Youngmi said to me and Incheol.

“Children, let’s study for the midterm at my house today.”

I said, pointing to Incheol.

“I was going to play basketball with In-cheol later… .”

In-cheol received my words.

“Today is a bathing ceremony. There will be bloody revenge for the ice cream lost yesterday!”

“However much! then… Two ice creams today?”

“OK! call!”

Youngmi made an impression and said to me.

“Hey, Chae Jung-ho!”

“Yes?”

“You decided to study hard this time. Have you already forgotten that we promised to go to the contest together?”

It was last Sunday.

At the words of Anglo-American saying that we should prepare well for the midterm exam and enter the science contest together… .

I made a promise to do so by accident, but there was no reason why Young-Mi’s parents encouraged them together.

‘Study hard and go to the contest together.’

You say this… .

‘I do not like it. Can’t you just say, ‘I won’t study hard.’

Anyway, Young-mi took this promise a little seriously.

I also made an empty promise at first, but I thought that I could go to the contest with Youngmi and make good memories.

After all, I was planning to raise my grades little by little, so I decided that getting good grades in this midterm was not bad, and I even had my own plans in place.

I told Youngmi.

“Young-miya, can’t we just play until today and study hard from tomorrow?”

Young-mi’s expressionless expression, shaking her head, is quite serious.

I turned my head and said to Incheol.

“Incheol-ah… sorry.”

“Chae Jung-ho, how dare you hit a betrayal like this… I was going to show you Michael Jordan’s special move today… .”

Then Yeong-mi said to In-cheol.

“In-cheol-ah, let’s come and study together. yes?”

“No! But let’s make one thing clear. I’m not doing this because I don’t like studying.”

Incheol pointed at me and continued talking.

“It’s because I can’t study with a traitor like this, so study hard with yourselves.”

When you see this… Incheol seems to have a good eye.

boy… .

Youngmi’s house.

While studying, I asked Yeong-mi a bit.

“Young-miya, how many points did you score in the final exam last semester?”

“Why?”

“You said you have to be in the top 10 in the whole school to enter the contest? I was curious about how many points it would have to be in order to be in the top 10.”

I don’t know the score of Yeong-mi, but I do know that she finished third in the final exam.

“I got 98.2 points.”

“Wow—! I don’t think I’ll be in the top 10 of the whole school.”

Yeong-mi continued with a look on her face.

“How do you know without even trying? And my score was only for you, so if you tell anyone else, you die.”

Yeong-mi clenched a small fist and showed it to me, and I nodded with a serious expression.

My plan for this midterm exam is as follows.

The first place in our school is a child named Yeonji Lim, and Cheolho, Yeongmi, Sangtaek, and Jaeyoung from 2nd to 5th place.

I’m a little sorry for the 6th place kid… .

I don’t know who I am from 6th place onwards.

When I asked the other children, none of them knew who was in sixth place.

So my goal was to be somewhere between 6th and 10th.

Of course, even if I get first place in the whole school, it won’t be published in the newspapers, but I just hate getting attention from other people.

To be honest… scary.

Not yet… I don’t have the confidence to accept people’s jealousy.

To put it bluntly, it is a trauma from the past life.

Considering the fact that memories from past lives are of great help… I think this kind of trauma is worth it.

And now when I’m older and I’m an adult… I hope that these trauma symptoms will get better little by little.

Anyway, let’s talk a little bit more about my midterm exam plan.

There is a theory in probabilistic statistics called the central limit theorem.

The theory is that if the number of samples is large enough, a given random variable follows a normal distribution.

In simple terms, it means that the distribution is in the shape of an upside-down, symmetrical, pretty bell.

Of course, there are a few exceptions, one of which is students’ test scores.

The reason students’ test scores do not follow the standard normal distribution is because the limit of 100 points is set.

For example, assuming that students’ test scores follow a normal distribution, there should be a student with a low probability of getting a score of 105 or 110, but in the real world, a score higher than 100 is impossible.

So, as a result of mathematicians’ research, students’ test scores follow a logit normal distribution.

The logit normal distribution can be calculated by taking a simple log function on the random variable of the standard normal distribution.

There are a total of 579 students in our school year, and Lim Yeon-ji, who is number one in the whole school, said through a school broadcast that she made a ridiculous mistake in the last final exam, and as a result, she got only one question wrong.

In other words. That means you got a score of 99.8.

Yeongmi (3rd place) scored 98.2 points, I (139th place) got 80.0 points, Incheol (487th place) got 46.2 points, and the grade point average was 64.9 points.

Based on these information, the expected standard deviation was calculated, and the logit normal distribution was calculated using the obtained standard deviation.

According to the calculated logit normal distribution value… .

The 6th place in the top 1.04% of all schools is at 96.2 points, and the 10th in the top 1.73% in the whole school is at 92.1 points.

That is, assuming that the difficulty of this midterm exam is similar to the last final exam… If you get a score between 92.1 and 96.2, it means you can get anywhere between 6th and 10th in the whole school.

“Boy! Chae Jung-ho!”

“Yes? did you call me?”

“What are you thinking so blankly?”

“ah… ! Nothing. I was just thinking about how to prepare for the midterm exam.”

Youngmi laughed at my answer.

“If you just think blankly like that, do you come up with an answer? You have to study, you idiot.”

So I was studying with Youngmi.

Young-mi’s father came home from work, and I said hello to Young-mi’s father and remembered today’s date.

November 5th.

And Young-mi’s father looks very healthy.

A few days ago, I started to feel a little more confident, and since I checked it myself today… Now I have come to the conclusion that there is no need to hesitate any longer.

That evening.

When I got home, I called Team Leader Kim Jeong-soo and made an appointment to meet with him two days later.

two days later… A park near the neighborhood.

In my last life, when I said that Yeong-mi’s father’s death was on November 2, team leader Kim Jung-soo opened his mouth with an annoyed expression.

“It’s all over. You asked for help, so I even made an alibi for Sangin Kim.”

“I know. Then I saw… I couldn’t even say thank you properly back then.”

I got up from the park bench and nodded towards him.

“thank you.”

At my greeting, Team Leader Kim Jung-soo smiled and said.

“Looking at his tone and actions, he is an old-fashioned young man… . It seems right to return.”

At his words, I also smiled slightly.

“Actually, I have a story I want to tell you, so I told you about the death of Sang-in Kim.”

“… ?”

“Now, Director Kim Sang-in is very healthy. In other words, I think his fate has changed.”

At my words, Team Leader Kim Jung-soo nodded as if it was natural, and I continued.

“So I mean… There is an accident at Seongsu Bridge.”

I could see his expression hardening with the words Seongsu Bridge.

I listened carefully to his reaction.

“I… Could such an accident be prevented? I’ve been thinking about it.”

Team leader Kim Jeong-soo took out a cigarette, lit it, and opened his mouth, exhaling cigarette smoke.

“You want to play a hero?”

I raised my voice at his sarcastic tone.

“It’s not a game! I want to save people who are innocently sacrificed!”

“… … .”

He didn’t say anything for a long time.

As the cigarette he was smoking got shorter, he dropped a butt on the floor and rubbed it with his feet, then pulled out a second cigarette and lit it again.

After finishing the second cigarette like that… He opened his mouth with a long sigh.

“It was when I first came back. One morning, I went to work, checked the list of all-night incidents, and there was one incident of violence in an entertainment district. It was a petty fight between drunkards in a bar… When I said that I would take charge of the case myself, there was a time when the criminal department of the Gangseo Police Station was turned upside down.”

“why?”

“At that time, I was the best detective at the Gangseo Police Station. He had the title of the youngest detective chief, and was about to be promoted soon. But in fact… There was a reason why I took on the case.”

“which… Why?”

“The civil engineering professor at Hankuk University was involved in that case. The professor was actually the victim of the case… I scared you a little. Because he was only studying, he didn’t even say a few words… I quickly got tired of it.”

He continued with a bitter smile.

“On condition that he be released without charge, I asked the professor a favor. I like your words, please… In fact, it was a threat.”

He took out his cigarette again, lit it, and continued the conversation.

“What was your request… It was a request to investigate the connection between the piers of Seongsu Bridge and the slabs placed between the piers.”

“… !”

“After about a week, the news came out. I mean, Seongsu Bridge was on the verge of collapse. From the morning of the next day, the Seongsu Bridge was controlled and the reinforcement work started immediately.”

“Ah—, I’m really glad.”

In contrast to my smiling expression, Team Leader Kim Jung-soo’s expression was severely distorted.

“But after four months… … There was an accident. This… I can’t remember at all… It was a new accident… .”

He dropped his cigarette on the floor and buried his face in both hands.

After a while, he raised his head and said.

“I have lived more than 20 lives so far… It was the first and the last such a terrible accident.”

“… ?”

“The Dangsan Railway Bridge collapsed. It was time for work… It was a huge accident where both 10-car subways running in both directions fell under the bridge.”

“… !”

“In that accident… … Only the dead… … … Over 1800 people. Exactly… 1823 people died… 1521 people were seriously injured and 61 people were missing.”

“… … .”

“Strictly speaking… Then the victims… All… It’s like it happened because of me.”

Tears welled up in his eyes as he let out a long sigh.

He said stroking my shoulder.

“okay… You might be thinking that you want to prevent the Seongsu Bridge accident. Because we already know the future… . But with you… I don’t know if it’s a small event, but I’m determined to change the world… I don’t want to make such a grandiose attempt.”

“… … .”

“Because the world is far more complex than you could ever expect… .”

Silence passed, and after silence I opened my mouth.

“The story of Dangsan Railway Bridge… Thank you for doing it. I almost made a huge mistake.”

I continued talking while looking at his expression.

“actually… I have a few more questions… May I ask?”

He nodded slowly at my question.
