224 – EP.10 Problem Child-2
***
The woman continued to place her hand on my forehead and tilt it.
I couldn’t overcome my shyness and put my head back.
The other person seemed to have come to their senses by my uncooperative reaction, so they raised both hands.
“Oh, sorry….”
She put her hand on the makeshift chair and spread the distance between them.
The distance is about 30cm, but I think the psychological gap is probably even greater.
She removed her hand from her forehead and took out her textbook from her bag again.
Thick books went up to the desk.
Suddenly, a book with a blue cover slides towards me.
Perhaps this is a textbook I will use.
The cover of the book said ‘Mathematics (Prize)’.
“Do you study with this book?”
When I asked, she muttered as if complaining.
“You’re the one who always says you lost your textbooks. That’s why I carry them with me.”
It was a voice filled with some irritation and anger.
At that sensitive reaction, I pursed my lips and grabbed the book.
It’s a textbook… I wonder how long it’s been since I last read it.
I built up a wall between studying after getting a job…
The table of contents is visible.
Polynomials, equations and inequalities… Geometry.
Concepts that seem familiar and unfamiliar come into view.
Uh… Was the original curriculum like this?
“Okay, then let’s start class.”
As we were looking around, flipping through textbooks, the woman spoke in a voice without any expectations.
“Oh, wait a minute. I need a writing instrument.”
It doesn’t make sense to participate in class and not have anything to write about.
I looked around the cluttered desk and picked up the black Monami ballpoint pen that was rolling around in the corner.
“…What are you planning?”
As I looked at her with her pen in hand, the woman frowned and said,
“Huh? Let’s go to class.”
I opened my eyes and protested.
“So… You’re going to take the ‘class’?”
“Why, can’t I take class? It’s… A private tutor?”
I was wondering for a moment whether it was tutoring or homeschooling, but the more likely option was tutoring.
In response to my confident attitude, the woman pressed her fingers to her temples.
It looks like you have a headache.
“hehehe… Let’s be patient, Yoon Sia.”
Through her self-hypnotizing mutterings, I learned her name.
Yoon Sia.
After closing her eyes and pressing her head for a while, she returned to her calm face.
“Okay, since you said you would take the class, there’s nothing to worry about, right? You can’t leave midway or lie down on the bed and sleep like last time.”
What kind of life was the owner of this body living?
If you recall the messy state of the room, you can probably guess roughly.
After class, I should do as much research as I can.
***
My high school life wasn’t that fun. Because there was so much pressure for grades, I couldn’t enjoy studying itself.
In that sense, high school math was fun in its own way as simple knowledge without pressure.
Yoon Sia’s class was the act of pulling out knowledge from deep within the library of her memories and blowing away the white dust that had settled on it with her mouth.
“Try to solve this problem here.”
She pointed to her page titled ‘Basic Concept Summary’.
I picked up a Monami ballpoint pen.
Problem number 1… It is a simple factorization problem.
After completing the calculations in my head, I put the pen to the paper.
‘(X+4)(x+2)’
No matter how much time has passed since I graduated from high school, it is too easy a question.
“…….”
I could feel Yun Sia’s gaze staring at me as I tried to solve the problem without hesitation.
It took about 5 minutes to solve all the basic problems.
“Uhm….”
Yoon Sia’s eyes were seen oscillating from side to side as she graded with her red pen.
The more she drew a red circle on the question, the more suspicious she looked.
After two hours of class, Yoon Sia glanced at me as she was organizing her bag.
“Kang In-ho, what are you planning?”
I didn’t know what to ask.
If a student who was normally uncooperative changes her attitude overnight and starts taking class, you will probably be suspicious rather than thinking it’s amazing.
“It’s just that. I wanted to hear it.”
I will live properly from now on. I didn’t even bring up a story that wouldn’t work.
It would be better to just gloss over it and say that I heard it because I was interested.
“Really?”
I guess I made the right choice, as I saw her expression brighten slightly.
As soon as she finished organizing her bag, she got up from her seat and folded up the simple chair.
“I hope that interest continues.”
“Well, I’m not sure about that.”
When I shrugged my shoulders and spoke indifferently, Yoon Sia looked at me like that.
“You told me to leave it behind… So you’re leaving the textbook here?”
Yoon Sia checked again and left her textbook on her desk.
I left her room with Yoon Sia.
I go down from the 2nd floor to the 1st floor and look around the house.
It is a nice and spacious house.
“I’ll come on Wednesday. Pre-study, review… If I’m interested.”
She put emphasis on the word ‘interest’.
“Goodbye.”
When I greeted her at her front door, she tilted her head as if it was really strange.
“Is he really eating something wrong?”
“I can hear everything.”
When I glared at her with her cold, salty eyes, Yoon Sia looked at me as if she felt aggrieved.
“No, it’s funny even if you think about it. Just a few days ago, you didn’t even treat me like a person… I don’t know why you’re suddenly like this?”
“…I won’t comment on that.”
“Ah… No way, you, Inho!”
Yun Sia clapped her hands and pointed at me with her finger.
The gesture is as if the person has discovered a huge fact.
“You got caught and beaten by your father?”
“No.”
I don’t know, it could be real.
“What… No? Then what…”
She had a thoughtful look on her face the whole time she left the house.
Oh, I was going to ask her how she got the keys, but she forgot.
***
The first thing I did after sending Yoon Shia off was to change the password on her door lock.
I reset it from the inside and changed it to a number I know.
It looks like you need a key for the main door, and this was found in the room.
“Now… Let’s look at the phone.”
After searching the room, I found a cell phone under the bed.
Hold the black liquid crystal screen at an angle and look at the handprint. The marks of hand rubbing appear long.
Among those trajectories, we will infer and draw the most common one.
After several attempts, the phone was unlocked.
“Let’s see….”
I sit down on the bed and open KakaoTalk.
There are quite a lot of messages, so I go to the room where there are a lot of messages.
Did you buy alcohol?
How are you going to get new clothes this time?
Where is the smoking hole?
Let’s play at the motel.
Let’s rent a car and go to the beach to get some fresh air.
Hmm….
Just when I thought I was possessed by a pretty bad guy, I received a message from someone.

Jeongah♡: Inho, are you awake? Jintae said he drank alcohol today, so she said let’s go to a karaoke bar and eat.
