next day.
I gave the business card I received from the owner of Sepia to my mother, who carefully checked the business card and said:
“His name was Kang Sang-soo.”
Sangsoo Uncle.
Uncle was my mother’s boyfriend last life.
It sounds a bit strange to say that he is my mother’s boyfriend, but in the past life my mother did not marry Sangsoo Uncle, and called him boyfriend.
This is the so-called American style.
Last Life The first time my mother and Uncle Sang-soo met, right after we returned to Korea from the United States, the situation was similar back then.
My mother had an accident while parked in parallel, and the owner of the car was Uncle Sang-soo.
Of course, his car at that time was not a used Sepia, but a new Sonata.
The two quickly became close, and about two years after they met, the man proposed to his mother.
At that time, the mother rejected the uncle’s proposal, but after the proposal, the two began to live together and share a bond that is more than a couple.
And the most important thing is… .
The point is that after meeting Sang-soo, her mother has changed a lot.
Until then, I didn’t know that my mother was such a laughing person.
I said to the mother who checked the business card.
“I sent 1 million won to his account.”
My mother said with a surprised expression.
“really? Is it that expensive to replace a bumper?”
I said with a slight smile.
“I asked the repair shop while making a reservation for our car, and they said that the sepia was discontinued and would cost that much.”
That’s a lie.
past life.
The money that my mother sent to Sang-soo the day after the accident was 1 million won.
At the time of the accident, my mother was driving a car that was borrowed from a relative, and my mother had sent a generous amount of money to fear that Uncle Sang-soo would take care of the insurance.
Uncle Sangsoo met his mother again to repair the car and return the remaining money, and the two began their relationship while having a meal that day.
I held out an envelope to my mother and continued.
“Yesterday I got my salary from Balhae Sports and Yunseong Soft.”
Mother said with a smile.
“So, are you giving your mom pocket money?”
The mother, who checked the envelope, said with a curious expression.
“What is this? What receipt… Do you think?”
“This is a famous hair salon on the main road intersection.”
“beauty salon?”
“I think it’s been a long time since I’ve shaved my mom, so I want you to go there tomorrow morning and get a haircut.”
Mother said with tears in her eyes.
“He’s doing something he wouldn’t do today. That’s why you said leave time tomorrow morning?”
I said with a smirk.
“You can’t even cancel it, so you have to go.”
early morning the next day.
A text came in.
it was built
＜Please check your e-mail account for Yunseong Soft! I guess Incheol is in a hurry!>
I sent a text message to the author and turned on the computer.
In the inbox, there was an email sent by Incheol about 10 minutes ago.
+ +
Jeong Ho-ya,
There was just an earthquake!
oh my god!
It’s really cool!
ah! right! Earthquakes don’t matter now.
Send the security certificate file as an attachment.
Please send me the zero value used to convert the reject function.
really! When sending a zero value, send it to [email protected], not to Yunseong Soft’s email.
Internet speed in Japan is really desperate.
I’m not lying, it took me just 47 minutes to log in to Yunseong Soft’s email now.
So I sold a new yahoo japan account, so please send it there.
Then please!
See you tomorrow at Gimpo Airport!

The file attached to the email was a computer security certificate.
It was a certificate using the RSA encryption method, and when the certificate file was opened with a text reader, the RSA coefficient N value and the lock key E value came out. In Cheol-i’s words, he meant to send the non-name zero value of the Riemann zeta function to obtain the D value of the unlocking key of this RSA encryption system.
However, the account ‘leahkim’ is a bit strange.
For reference, Incheol is Choi, not Kim, and Leah is a female name.
Incheol, this guy…
What the hell are you doing in Japan?
There are only three people in this world, Professor Park Bo-sun, In-cheol-i, and I, who know the specific method of incapacitating the RSA encryption system by using the non-name zero value of the Riemann zeta function.
In other words, even if the corresponding zero value is sent to the leahkim account, it cannot be used unless it is Incheol.
It felt a bit awkward, but I sent the zero point value as In-cheol asked.
Two days later at 10pm.
Gimpo International Airport.
“hey! Why is your face like that?”
In-cheol’s face was literally cut in half.
At my words, Incheol sighed deeply and said.
“eww… I hardly slept in three days. I’m tired of dying I didn’t have time to go to the bathroom because I was busy.”
In-cheol continued, putting his bag in the trunk of the car.
“uh… ? Why is the bumper here? Did you happen to buy something while coming here?”
“no. It was an accident a few days ago.”
So In-cheol and I got into the car, and we exited the airport parking lot.
In-cheol, who sat in the passenger seat, yawned and said,
“eww… I feel tired.”
“What did you do in Japan, did you have half your face?”
In response to my question, Incheol smiled and said.
“Well, I was busy wandering around the tiger den.”
“Tiger oysters?”
Incheol nodded and said.
“To catch a tiger, you have to go into the tiger’s den.”
What kind of nonsense is this again?
After all the final exams are over next week, Incheol goes to Japan for two months for language training.
Originally, he was going to go with the author, but the author’s application for a Japanese visa was rejected, so In-cheol decided to go alone.
Anyway, the reason Incheol went to Tokyo for 3 nights and 4 days this time was to sign a contract for a dormitory for the next two months.
“Is it that hard to find a room in Tokyo?”
“ah… right! sleeping room! I was eating it… .”
“what? Aren’t you going to look for a room?”
“It was. Somehow it seemed that I was missing something. haha–!”
weird.
In fact, it makes no sense to go to Japan to sign a contract for a dormitory for two months.
I asked Incheol with a serious expression.
“What did you really do in Japan? What are you up to?”
“men and horses! What do you decorate? It’s not like I’m making a pretty face.”
Without realizing it, I was fed up and laughed.
ah… ! I hate myself for laughing
I said with a short sigh.
“Then why did you ask me to tell you the zero value two days ago?”
“ah… ! I asked for it because there was information I needed to know a little urgently… So thank you thank you! thank you!”
I turned my head and glanced at In-cheol, but even if I ask more, I don’t think In-cheol will tell me where he wrote the zero value.
“But what the heck is Leah Kim?”
“Leah Kim? New Japanese email account?”
“yes.”
“How about that?”
“In-cheol-ah, do you not know how to name English?”
“It’s an English name, you can make it up roughly. Do Koreans even need to know how to name English?”
“Anyway, Leah is a female name.”
“ah… ! Is that so? Hmm… Well, it doesn’t matter. It wasn’t made in English anyway.”
“Isn’t that an English name?”
In response to my question, Incheol smiled and said.
“Yeah, that’s my christening name.”
“If it’s your baptismal name… Michael?”
“right!”
“The name Leah Kim came from Michael? how?”
Instead of answering, Incheol pointed forward and said.
“When you get out of this Nambu Beltway, turn left at the intersection.”
If you turn left, it is in the northwest direction.
“Aren’t you going home?”
“I have a place to stop by before I go home.”
In front of the author’s house in Northwest-dong.
Incheol said as he grabbed his bag from the trunk.
“Thank you, Jeongho. Be careful and go in.”
“It is 11 o’clock at night. If it doesn’t take long, I’ll wait.”
“No, it might take a while. Next time I go to my house, I’ll take a taxi, so go in first. Thank you so much for today.”
The moment you get into the car.
Incheol’s voice was heard.
“ah… ! right! Jung Ho!”
“yes?”
Incheol took out a small box from his bag and handed it to me.
“What is this?”
“gift!”
“Five–! thank you!”
Incheol said with a playful expression on his face.
“You write it secretly, okay?”
“What, what?!”
In-cheol waved and went into Ji-eun’s house, and I got into the car and headed home.
In-cheol is this guy…
What the hell are you doing in Japan?

Tokyo Asagusa Police Station Transportation Department.
“(Oh my! This pink diskette is so pretty. Where did you buy it?)”
“(I didn’t buy it, I got it today at the entrance of the police station as an event.)”
“(event?)”
“(Yes, I said there was a promotion at the electronics store across the street.)”
“(I did. But it’s so pretty. Why didn’t I get it?)”
“(Then Chizuru-senpai will write it?)”
“(Really? Would that be okay?)”
“(sure.)”
The male employee continued to speak by handing out a diskette to his senior.
“(When I opened the compressed folder, it said there was a coupon file in it. Check it out now.)”
“(Satoshi, thank you.)”
She said as she put the diskette into her computer and checked the files.
“(Uh…? Nothing in the compressed folder here?)”
“(Is that so? Shall I check it out?”)

same day.
Tokyo Harijuku Police Department Civil Safety Department Civil Service Office.
A police officer handed a floppy diskette to one of his subordinates and said:
“(Hey! Sergeant Watanabe, isn’t this yours?)”
Shun Watanabe looked at the diskette and shook his head.
“(no.)”
“(Did it fall on the floor over there?)”
“(Maybe the resident who came to the complaint lost it? I will check it once.)”
He put the diskette in his computer, checked the folder, said.
“(There is one compressed file… wait a minute.)”
“(….)”
“(Hmm… nothing. I think it’s just a blank diskette.)”
“(Yes? Just in case you don’t know, put it in the loss box at the civil service office.)”
“(all right.)”

the next morning.
Tokyo Yotsuya Police Station Criminal Investigation Office.
A police officer returning from vacation called his subordinate.
“(Sergeant Tanabe!)”
“(Yes, Manager Kuboda!)”
Inspector Kuboda said, pointing to his desk.
“(Here’s a floppy diskette, you know what?)”
“(I was there a few days ago… Isn’t that Kuboda-san’s diskette?)”
“(Not mine.)”
“(Then I think another employee left it by mistake, let’s check it out, right?)”
“(Is that so?)”
He put the diskette in his computer, opened the folder and checked the compressed file, he said.
“(Nothing? It’s empty.)”
* * *
the same afternoon.
The office of the head of the police department at the Tokyo Honjo Police Station.
Kaneshige checked each of the mail that the secretary had organized and brought.
One of the mail was a small parcel from the Taito Ward Merchants Association.
Upon opening the package, a short letter appeared.
The letter stated that the Merchants Association had prepared an event for the police during the fireworks festival in July.
Sergeant Kaneshige muttered to himself.
“(An event for the police? Was there such a thing?)”
He continued to read the letter.
During the fireworks festival, it was written that free drinks were provided to police officers who are suffering from security activities, and coupons for each restaurant participating in the event were contained in the enclosed floppy diskette.
In particular, it was written that the pink cherry blossom meal coupons that can be used at high-end restaurants can only be used by executives above the rank of police officer.
Kaneshige put the floppy diskette into his computer and clicked the compressed file icon.
“(What? Nothing? Is it a prank letter?)”
