On a dull day, it seems that there is always sweet boiled water.

At least for Moon Young-heng, the life of Yoo Ji-min is only a wall away, and there is some sugar hidden everywhere.

After waking up early, he made a cup of coffee for Yoo Jimin, and gave it to Yoo Jimin, who also got up early, before the other members got up.

In the past, Yoo Jimin was the first to sleep in the team, but recently, she has always had some insomnia.

So a cup of coffee in the morning, with a little sweet bitterness, can give her energy for the day.

When preparing for the various stages at the end of the year in advance, I was also more energetic.

On the other hand, Moon Young-heng continued to go through various onboarding procedures with the administrative teacher, and finally completed all the steps after coming to Seoul a week later.

In the first few weeks, a senior professor will observe his course to fully assess the quality of his teaching and give his opinion accordingly.

There are also some details about courseware and the use of textbooks, which are quite troublesome to deal with.

Moreover, Wen Yingheng's business administration department has many overlapping courses with the economics department, and these courses are naturally arranged for him, a new teacher.

In addition to the originally determined "Statistics" and "Operations Research", Wen Yingheng also has to teach a university-grade "Principles of Economics" this semester.

Moon Young-heng likes to share these things at work, and Yoo Jimin will understand these things he says word by word in his spare time.

Of course, more often than not, the messages sent by Wen Yingheng in the past are always in a state of "not being read".

However, for people who have been separated from each other for many years, these are nothing.

On the contrary, it is Kim Jisoo, who has excellent academic talent and willpower.

Even if there are some out-of-the-ordinary questions, Kim Jisoo will cleverly use the Internet and search engines to help him get answers step by step.

Sometimes, however, she pulls out her phone, takes a picture of something she doesn't understand, and sends it to someone with the caption "Dr. Wen."

After the note, a contemplative emoji was added.

Usually one minute after the post, Dr. Wen will send a video recorded with a pad.

Unbiased text accompanied by audio recordings, he will explain in the simplest way possible how this formula is derived, and what is commonly used.

For example, some commonly used high-level infinitesimal are a little difficult for Kim Jisoo who is just getting started, but Moon Youngheng compares them to the relationship between father and sons, and through some simple calculations and the combination of numbers and shapes, she can instantly understand the connection.

It was during this week that she was able to get started with differentiation.

"Let's talk about this question after class," Wen Yingheng pushed his glasses: "Are you sure you won't be recognized if you dress like this?"

In Wen Yingheng's office, there was a girl dressed a little casually.

Even if it is light makeup, it still has a unique temperament that can be recognized at a glance in the crowd.

The long hair that is slightly curly covers the shoulders, and the round-framed glasses are framed on the bridge of the nose, giving the face a more three-dimensional and durable appearance.

Kim Jisoo bit the cap of his pen slightly, completely immersed in the math problem, and didn't seem to hear his words.

Wen Yingheng glanced at his watch and said helplessly: "If you don't leave, I'm going to be late."

After about ten seconds, the girl's originally frowning eyebrows stretched slightly, and her lips were curled, revealing her white and neat teeth.

The tip of the pen rubbed the white paper and wrote down the answer that satisfied her.

"It's solved!" She stood up and pushed Wen Yingheng out: "Don't worry, you won't be recognized."

Despite having said that, Kim Jisoo cautiously hid behind him, while also covering her distinctive love lips with a black mask.

Today, Wen Yingheng teaches "Statistics" for the lower grades, and because it is a public course for several majors, it is arranged in the lecture hall.

As soon as Kim Jisoo entered the door, he naturally picked up a middle seat and sat down.

Next to her was an old woman with gray hair.

"At such an age, are you still insisting on studying?"

Kim Jisoo's heart couldn't help but feel a little awe.

But this awe was quickly diluted by the impact of "Statistics".

Through the mask, I habitually bite the tip of the pen again.

Kim Jisoo found that the differentiation she was learning was not the same as what Moon Young-heng was teaching today.

Although it is a bit difficult to understand, Wen Yingheng's lectures are very humorous, and he can explain a principle clearly with the most simple and straightforward metaphors.

So, taking notes went well.

"Girl, are you a little unable to keep up with the pace of class?"

The old woman smiled and glanced at her notebook.

Next to the knowledge point about the "sample", I don't know when I drew a stick figure of the villain.

At first glance, it looks like the high-spirited young teacher on the podium.

"Yes...... Actually, I'm an auditor, and some things are a bit difficult to understand. ”

The old woman bowed slightly: "I can see it, your definition here, in fact, you don't need to remember it in such straightforward words." It is easy to cause misunderstandings when reviewing in the future. ”

"But if you're an auditor, there's nothing wrong with that, just understand."

The old woman only pointed out a few questions, and Kim Jisoo felt that she was faintly sweating.

Xu saw Kim Jisoo's nervousness, and the old woman smiled slightly: "You have to have confidence."

Kim Jisoo realized that the old woman might also be a senior professor or something, so he put away his hand holding his chin: "Professor Moon gives a good lecture, I will study hard."

The old woman looked at Wen Yingheng on the podium, although she was still calmly telling the knowledge about the sample, but her eyes drifted towards this place coldly.

"He gives a good lecture, but you also have to have faith in Jisoo."

Kim Jisoo subconsciously bowed slightly, and after a while, he sensed that something was wrong.

How could this old woman know herself.

"I love to drink sugar-free Sprite, and you're the face of it, right?" The old woman pushed the notebook over: "My granddaughter likes you too, can you sign autographs for both of us?"

The two statistics classes were over quickly.

In Kim Ji-so's mind, half of it is the knowledge that Moon Young-heng said, and half of it is the impact that her grandmother brought her.

From her, it seems that she can feel the vitality and vitality given to her by knowledge, and at the same time, she feels the feeling of being recognized.

"As long as you are willing to work hard, if you can mix in the entertainment industry, there is no reason why you can't learn this knowledge."

In order not to affect the order of the class, the old woman leaned into her ear and said, "If there is anything that you can't do, you can ask Professor Wen more." Or ask me too. ”

Wen Yingheng, holding the lesson plan and courseware in his right hand, and his left hand slightly blocking the distance between him and the students, moved towards the office step by step with difficulty.

"Students, if you have any problems, we will solve them one by one......"

Surrounded by water, he glanced at Kim Jisoo again.

The girl and the head of the department stood side by side, glanced at this side in tacit understanding, and lowered their heads and smiled.

"Are you sure you're going to wait until he's done with the job at hand?"

Kim Jisoo hesitated: "My bag is still in his office......"

"Got it, you can wait in my office first."

And the SM practice room at this time.

Yoo Jimin sat on the floor, taking advantage of the rest moment to play with his phone.

A NAVER hot search caught his attention.

The slender eyebrows frowned slightly, the girl rubbed her nose, and said angrily: "This guy ...... See how you explain it to me......"
