On Friday morning, Su Mu didn't have any classes.

Unlike high school, college students have a lot of free time, and if they don't have classes in the morning, it's equivalent to a half-day off.

Of course, because of the large amount of homework, many students choose to go to the library to study and write homework on their own.

As usual, Su Mu carried his small schoolbag and continued to find a place to start studying his homogeneous differential equations, preparing to complete all the contents of this small point today.

The tables in the library are actually quite large, with one table having four stools that can seat four students.

If it's not a weekend, the location will be a little more vacant, and there will usually be two people sharing a table, so the space is larger.

Su Mu put out his book and took out a pen and paper to calculate carefully, and when he was calculating the core points, he was a little excited to make a summary, when he suddenly smelled a special fragrance, and then saw a figure sitting opposite him.

Raising his head slightly, he glanced at a girl sitting across from him, who put down her long pink schoolbag and sat down.

With a ball head, he is very tall.

The face has a layer of white foundation, which should be carefully put on makeup.

Su Mu frowned slightly.

The strange scent on the girl's body is definitely not a body odor, but the smell of perfume.

His senses are a little more sensitive than the others, so he feels a very strong perfume smell.

The nib paused slightly, but didn't say anything.

His calculations were now at a critical juncture, and there was no need for an outsider to interrupt his train of thought.

"Hello classmates.... Can you lend me a pen?"

Originally, Su Mu had already planned not to mind.

But unexpectedly, the girl opposite took the initiative to greet Su Mu and showed a sweet smile.

The girl's voice was not bad, and she spoke in a polite tone.

“.....”

Su Mu originally wanted to refuse.

For example, find an excuse that "he doesn't have much pen anymore".

But for the convenience of calculation, he has three or four pens on his desk every day, and it is not good to directly open his eyes and say nonsense to reject others.

"Hmm."

Su Mu could only nod helplessly, and took one casually and sent it over.

"But I'm going to leave right away after I finish counting these things..."Su Mu opened his mouth to explain, he didn't want to have too much intersection with this girl.

"Okay, thank you, senior."

The girl continued to say sweetly, probably because she thought she looked cute.

The black line on Su Mu's face.

This girl does look good overall, but this kind of makeup is really not his favorite style.

What he likes most is Yan Xiaoke's natural plain makeup, or slight light makeup, and Su Mu actually doesn't like Yan Xiaoke to wear lipstick, because if he wears lipstick, it is not convenient to do many things.

The girl in front of her obviously had just touched up her makeup with lipstick on her mouth.

"I..."

Su Mu originally wanted to respond that he was not a senior, but he still chose to give up answering, the more he said, the more time he wasted, it was better to finish writing it quickly.

The library fell silent, except for the sound of everyone scribbling.

......

"Whew."

Finally finished, Su Mu breathed a deep sigh of relief.

He really had to admit that Venkatesh was really a genius, and some of his views on number theory and homogeneous dynamical systems were simply a different way.

Moreover, what Su Mu has sorted out now is only less than one-tenth of what he obtained from General Fields, and then there are things about topology and representation theory, which makes Su Mu even more interested.

With a slight movement of his wrist, Su Mu took out his mobile phone and prepared to relax.

Yan Xiaoke was full of classes this morning, and he had already sent a message to tell him if he wanted to go out for a meal together tonight.

Su Mu thought about it, there will be a campaign at the class meeting this afternoon, and there should be nothing to do after the election, so he agreed.

After so many days of school, he hasn't seen Yan Xiaoke's roommates yet, so he should find a time to meet him, and if Xiaoke has anything in the future, he can also ask them to help him more.

"Senior, are you done?"

"You're from the math department, right?"

Su Mu was still immersed in the pleasure of solving the problem, and suddenly, the girl opposite found this opportunity and began to talk to Su Mu again.

"I feel like you're so good at being able to write so many things at once."

The girl's tone was a little nervous, but overall it seemed to be fairly steady.

Su Mu was stunned for a moment, and then realized that he seemed to have been accosted.

"No, I'm just a little bit interested in math."

Su Mu smiled awkwardly.

"Can you show me? I'm actually very interested in mathematics, I'm a sophomore in the School of Things, and my name is Guan Pingwan. ”

Guan Pingwan wrote her name on a piece of paper.

handed it to Su Mu, and was very happy with Su Mu's response to him.

And when Su Mu raised his head and smiled at her, Guan Pingwan's face immediately became a little more flushed.

In fact, she has been observing Su Mu for a long time in the past few days.

Almost every day during the evening self-study time, there will be a handsome boy studying in this position on this floor.

She didn't know why, the first time she saw Su Mu, she was fascinated by the boy's focused expression.

Although she has also seen a lot of school tyrants, it is the first time she has seen a boy like Su Mu who can be completely addicted to and has such a temperament.

It just so happened that she didn't have much class on Friday today, so she just wanted to come over and try her luck, but she didn't expect to really run into this boy again!!

It just so happened that everyone was in class, and the flow of people in the library was much less, so Guan Pingwan hurriedly made up for it, plucked up the courage, and seized this opportunity to get to know Su Mu!!

"Monoin?? Sophomore? ”

Su Mu looked stunned.

He pondered, this girl who came to talk to him.

It's still one of my own senior sisters??

The gaze was a little kinder.

Since it is a senior sister in the same department, it must be respectful.

Even if the perfume smell is so strong, you can only endure it, otherwise it may be embarrassing to see it in the academy in the future.

Pushing his draft, he explained:

"Actually, there is nothing in these things, if you want to see it, take it and take a look, I'm not a senior, I'm also from the School of Things, and I'm a freshman this year."

"Freshmen?"

Guan Pingwan's face was a little surprised, she had actually seen the cover of Su Mu's book before.

There is something about number theory and differential equations, which makes her subconsciously think that Su Mu is a senior of the Academy of Mathematics.

"Hahaha, then we're quite fated." The corners of Guan Pingwan's mouth twitched.
