My sister can't be Ying Li Li

Hanabi felt a chill on her back. Yangno had seen through it all, and couldn't help but say, "Where did you collect the information from? I want it too."

"I promised Xiaojing that I would never betray her." Yang Nai said solemnly.

Hanabi: "..."

Yang Na probed: "For men, self-motivation is an important quality. What are your intentions after graduation? Are you in a hurry to find a job?"

"Who knows for sure what will happen in the future. I'll probably make the same choice as my sister, or just find a university close to home." Hanabi said casually.

Let’s set a small goal first and get the admission notice from Zaokei University (one of the four major private universities in Kanto).

"It's close to home..." Yangno smiled, "Hanabi-kun is really interesting."

Speaking of which, why do Hanabi and Yangno appear here? Let’s start from the beginning. Hanabi spent the whole morning walking around with Haruno. There was not much to go to in the small Otonogizaka, just old and new school buildings. So, Yang Na said that courtesy should reciprocate, and she wanted to take Hanabi to the university.

Hanabi was very curious about the university environment in Japan, so she readily agreed. Unexpectedly, it was at the level of "Eastern University". Yang Nai studied in the Department of Science and Engineering. He didn't care about academics. I'm afraid he went there for this business card and social circle.

Yang Nai suggested: "How about following the class with me?"

"May I?"

"It doesn't matter, no one knows you anyway." Yang Nai took out his mobile phone and looked through the class schedule, "Suddenly I remembered that I have an advanced mathematics class in the morning."

"So you have classes too?" Hanabi complained, "I thought college students were as free as you."

"You just said that, right?"

"Each other."

The two looked at each other and smiled.

This is a ladder classroom that can accommodate more than a hundred people, rising from the ground and extending backward. Yangno took Hanabi and slipped in quietly through the back door, then pretended to listen to the class seriously.

Some students noticed something strange and turned around to see Yukinoshita Yono and the unfamiliar blond man, and couldn't help but be surprised. Yukinoshita is an important student union cadre and a well-rounded social butterfly, but she has never been known to get close to a man, let alone go to class together.

Hanabi felt the eyes from all directions, and she was on pins and needles, and whispered: "It seems... there are many people looking at you. Are you famous here?"

"No, they are looking at you." Yangno said.

An old professor was writing furiously on the blackboard and turned around and said: "Be quiet, do you all understand? It's true, today's young people are inferior to each other. There are reports that the mathematics level of college students is getting worse and worse." If you don’t work hard now, you will suffer losses in the future.”

Yangno smiled slightly and made a "shh" gesture.

"Advanced mathematics is widely used in engineering. I'll ask a classmate to talk about this question..." The professor looked around, and everyone immediately lowered their heads, leaving only a blank look on their faces.

"The classmate who dyed his hair. Yes, that's you."

Hanabi's golden hair stood out among the group of black haired people. He stood up and said innocently: "Teacher, I am born with this."

All the students laughed faintly. Yang Nai was lying on the table trying hard not to laugh, her shoulders shaking.

The professor said: "Well, okay, even if you don't dye your hair. Don't you even bring a book to class? It seems that you have already learned it. Let's analyze it."

Hanabi cast a pleading look at Hinano, they didn't even have textbooks. Yang Na turned her face sideways, her long black hair scattered on the table, and looked at him with a smile, her sweet dimples looming, like her childhood beauty roommate.

You just want to see me make a fool of myself, right? I still have some impressions of mathematics and so on...

[Complete Memory], activate! Hanabi looks for the correct solution from the fragmented memories of her past life. After just a few seconds, he suddenly looked up, with a faint smile on his face, as if he had a plan in mind.

(The momentum has changed.)

Yangono opened his eyes wide.

"Truncate the cylindrical conductor to make a Gaussian surface, and then calculate the forward flux crossing the Gaussian surface..." Hanabi said eloquently, "Teacher, you made this question to give an example of the application of flux and gradient in engineering. ? But the content involving electric current and magnetic field is a bit difficult for us non-major students. This Gauss’ theorem was later summarized into Maxwell’s equations and is the introductory formula for engineering electromagnetic fields.”

Fortunately, mathematics knows no borders. If it were another class, Hanabi would be dumbfounded.

On that day, the science student finally recalled the fear of being dominated by Gauss and the humiliation of being imprisoned in Euler's formula.

There was silence in the classroom, and everyone was stunned.

"This classmate..." the professor pushed up his glasses and wondered, "You are right. But...why haven't I seen you before?"

Hanabi scratched her head and smiled cheerfully: "Maybe it's because I skipped too many classes."

"If you can study by yourself like you, I will give you credits even if you don't come to my class." The old professor sighed, "What's your name?"

"Yunoshita Harano." Hanabi smiled brightly.

Harano stepped on his feet with high heels. Hanabi's expression didn't change as she lightly kicked back and touched Harano's calf. A full show of martial arts under the table.

The professor said leisurely: "Okay, I've written it down."

After class, the two people fled this place of right and wrong.

"Hanabi-kun!" Yangno showed a kind smile, "What did you do with his name?"

"I helped you earn credits, so don't thank me too much, Sister Yangno."

"Thank you so much..." Yangno gritted her teeth with hatred, and then smiled, "Are you finally willing to change your title? It's really not frank, Hanabi-kun. Then I, my sister, will treat you to dinner."

The author has something to say:

PS: The labor and management have taken off their pants, so you want to show me high math?

Unexpectedly, I accidentally drove into a tram. Because it’s difficult to conquer a woman like Haruno.

Chapter 214 Sister’s Brilliance

There is a KFC not far from the school gate.

During the evening meal rush hour, Hanabi and Harano walked into the restaurant side by side. The consumption level here is most suitable for young couples in student days. Therefore, the two people, who are more like brother and sister, are incompatible with their surroundings.

People cast their surprised glances one after another on the handsome man and beautiful woman.

(That Yukinoshita... actually came here?)

Hanabi didn't know. Under Yukinoshita Haruno's conditions, boys who want to invite her to a candlelight dinner can line up in a long line from here to Tokyo University. And Yukinoshita is able to play with men's admiration in applause, never pretending to be pretentious, and just right enough to capture people's hearts, and appreciate their ugly behavior of being jealous and fighting.

(Who is that dishonest little boy? Did you make a mistake and treat Yukinoshita to such cheap fast food?)

The boys at other tables took a big bite of their burgers to vent their anger.

The two of them sat by the window.

Looking out the window, the Japanese streets are full of pedestrians, as if they are separated into two worlds by a thin layer of glass. And the pace of my life has slowed down, and I can enjoy inner peace.

Yangno ignored the surprised looks of others and smiled at Hanabi: "I thought little boys nowadays prefer Western fast food."

"I don't care. Can Sister Yangno accept junk food?"
