"You can review Probability Theory, and the basic knowledge of t-distribution and normal distribution is very important."

"This part of the time series will also be learned in the measurement, so don't worry if you don't understand it for the time being...... What? My Kakao account?"

Looking up in embarrassment, Moon Young-heng pretended to be the first time in Seoul: "Sorry, I haven't installed Kakao yet."

Huang Jingxi, a sophomore this year, was about to withdraw Kakao's QR code unwillingly, and the girlfriend next to her reminded: "Chinese use WeChat, and when Teacher Wen is studying at UCLA, he must also use Facebook social accounts."

Huang Jingxi's eyes lit up secretly: "I can register WeChat!"

Several other students standing behind her chimed in, each with a different purpose.

There are those who are close to each other for credits and grades, there are questions that they want to ask, and there are also things that cannot be described......

Wen Yingheng's social account is very simple, and there are not too many friends in it.

Because of the reason that he has been traveling around the world since he was a child, in addition to his family, mentors, and a few classmates, there are only friends like Yoo Jimin and Jung So-yeon...... Oh yes, and Jisoo with the note "Student-Kim Ji-so".

"Well, I'll give you the number, and you're responsible for organizing your classmates to join the chat group, where I can communicate with your classmates...... My mailbox, you should have already photographed it on the PPT. I should also be able to search for me directly in the school's email system. ”

Standing up and coping with the students being sent out of the office, the exhaustion from over-socializing gradually spreads from the back of the head to the whole body.

Pushing open the door in a daze, I saw a girl in her early sixties standing in the depths of the corridor.

The setting sun used the last afterglow to paint a layer of gold on her white coat, and her originally jet-black hair also shimmered with a slight brown sheen.

And that conspicuous dull hair.

Kim Jisoo pushed his glasses and moved slowly.

"It's still there, I thought you went first."

Wen Yingheng rubbed his eyebrows and listened to her walk towards the parking lot together.

"Have you forgotten? I'm here in your car," Kim Jisoo paused and emphatically said, "Back seat."

Strictly speaking, it was actually Zheng Suyan's old scooter, because she had changed to a new car before, so she gave this old car to Wen Yingheng to use.

"Oh, I almost forgot ......"

Wen Yingheng scratched his head in embarrassment: "Is there really no other itinerary?"

"I'm not an idler......" the girl gave him a helpless look.

"Oh, I didn't mean anything else, just curious. The gap between your idols' lives is quite large. ”

Subconsciously recalling Yoo Jimin's itinerary, Moon Yingheng grinned helplessly.

"You guys? Who is that idol friend of yours? Maybe I know each other. ”

Kim Jisoo consciously sat in the back row, chatting while opening the pad and reviewing the extra small stove that the head of the department gave her.

In the notebook, I neatly wrote a few practice questions from the professor himself.

You only need to apply the principle and substitute the data to get the answer, which is very suitable for consolidating the foundation.

"Oh...... Guess what?" didn't want to admit his relationship with Yoo Jimin frankly, Moon Young-heng chose to pretend to be mysterious with more peace of mind.

Because, he can't figure out his relationship with Yoo Jimin.

Far more than friends, but not a couple.

"I don't have time to guess ......"

Once he gets serious, Kim Jisoo becomes Jiso, preoccupying and leaving no stone unturned.

After verification, H0 was falsified and consistent with the reference answer.

The girl's lips opened slightly, wanting to continue the previous topic.

Just lift your eyes and see the rush hour, the brightly colored traffic lights, the skyscrapers in the distance, and the fading skyline.

There is also a vague back of serious driving in the afterglow.

For a moment, the atmosphere seemed like a relaxing time on the way out of school.

It's like an older brother picking up his sister from school. However, did Kim Junhyung take over Kim Ji-so?

In my memory, it seems that there is none.

At this moment, all the light, starryness, and fame faded, and Kim Jiso, who was shining on the stage, stopped imagining the future.

It's like the quantum superposition state collapsed into a result - that is the ordinary person Kim Ji-so.

Eh, wait, quantum superposition? What is that?

Kim Jisoo frowned slightly, as if amused by his own question.

A chuckle broke the silence in the car.

"What's wrong? There is still half an hour to get home. ”

If Moon Young-heng said next: "Is it okay for us to eat winter melon pork rib soup at night?", Kim Jisoo would not feel abrupt.

I pressed the window, and the cold wind passed through the gap, bringing a little coolness.

"Shhh...... Nothing, just a little pain in the neck. ”

"Brushing questions in the car, it's not good for the cervical spine, and won't you get motion sickness?"

"Not getting motion sickness is the basic professionalism of an artist."

With these words, Kim Jisoo found some characteristics that belonged to Jisoo.

But it feels a little strange.

She knew that it wasn't schizophrenia, it was just that she had been hesitating between different life states for too long, and everything had become strange.

"Looking at electronic screens in the dark is not good for the eyes......"

Kim Jisoo raised his head, only to find that the lights in the back row didn't know when they were turned on.

Without saying thank you, she leaned on the window and felt the wind at 33°N.

…………

Aespa dormitory.

Giselle and Yoo Jimin stood on the balcony together, silently watching the cars coming in and out of the community's door.

"He's supposed to be out of class, right?" Yoo Jimin glanced at the background of the chat interface, which was Moon Youngheng's class schedule.

He took the initiative to send it, but she didn't ask for it......

Thinking of this, his mouth grinned obliquely, revealing a mischievous and satisfied look.

"It's going to be a bit of a blockage." Giselle opened the map and looked at the streets, all yellow and red.

"This guy, can't you rent an apartment over there in Guanyue District?"

It's obviously complaining, but the tone is extraordinarily brisk.

"I said you, in fact, you can confirm the relationship with him earlier," Giselle analyzed seriously: "Anyway, there are so many idols who talk about underground romances." Moreover, if you fall in love with him, you don't have to take the elevator when you go out. ”

If you don't go out to play, Yoo Jimin can talk about a love that is impossible to leak.

Seeing that there was still hesitation on her face, Giselle added, "You've been running for so long...... Do you know the term seven-year itch?"

"Of course I understand the truth, but in that case, I can't be at my best...... In that case, wouldn't it be impossible for both of them to be responsible?"

Fingers were drawing circles on the balcony railing, and the girl was not confident in what she said.

"Miss, and imperfection, you have to choose one, we are idols, there is always sacrifice. He just came to Seoul National University to teach, and he was on the hot search because of his appearance...... Although this hot search did not last long. ”

In the afternoon, the push that made Yoo Jimin not very happy was called "Professor Moon Youngheng of Seoul National University", and the theme was "appearance".

Such a conversation made Yoo Jimin gradually resist.

At least, she doesn't want to face these problems now.

"Ernie, this black scarf looks good, should I match it?"

Jin Minjun's voice came from the living room, and Yoo Jimin frowned slightly: "...... black scarf?" No, you can take the rest. ”

The girl spun around and ran into the living room.

At the same time, Wen Yingheng's scooter drove into the community and drove in the direction of the parking lot below.

Giselle looked around, and finally sighed slightly.

After about two minutes, the car came to a smooth stop in the parking space.

Turning off the engine, unloading the seat belt, and glancing at the back seat, Moon Young-heng realized that Kim Ji-so didn't know when he fell asleep......
