Because he had accepted the setting that he would meet Yan Shu at any time, he was not surprised at all when he came to SSW's library as usual after Yu Gui finished tutoring this Sunday, and saw Yan Shu in the same position as last time.

That's right, not at all.

"Return!" Yan Shu noticed Yu Gui as soon as he entered the door, and there was a hint of certainty in his eyes, as if he had guessed that he would definitely see him here today.

Yu Gui was embarrassed to sit across the table from Yan Shu now, so he walked over and sat opposite him and said, "You don't go out for activities on Sunday nights?" What are you doing in the library? ”

"Aren't you the same?" Yan Shu smiled embarrassedly. He deliberately put his stool in when Yu Gui approached just now so that Yu Gui could walk next to him, but Yu Gui directly crossed him and sat on the opposite side, which made him feel a little disappointed.

And Yu Gui gently tugged the corners of his mouth after hearing Yan Shu's words and said: "I don't have the conditions to go out for activities, and coming to the library is the most convenient and economical, and you are different from me." ”

"It's nothing different...... Yan Shu's face flushed slightly, as if he was a little shy, "I just, I just like to come to the library." ”

Yu Gui looked at the blush on his face and couldn't help but say funny: "What are you blushing, you know that you are saying that you like the library, and those who don't know think that you like someone here." ”

Yu Gui's sentence was originally an unintentional joke, and he said it just to liven up the atmosphere, but he didn't expect that after he finished speaking, he found that the color on Yan Shu's cheeks became darker and darker.

Belch...... He couldn't have really been right?

Yu Gui felt speechless, he did not have the habit and interest of spying on other people's hearts, and immediately apologized to Yan Shu: "I'm sorry, I made a little too much of a joke just now, don't you mind." ”

"Ah......?" Before Yan Shu could recover from the question just now, he was even more confused by Yu Gui's sudden apology, and his face was full of words, 'Why can't I keep up with your rhythm?' ’

And his expression made Yu Gui stunned, if the two of them could see each other's thoughts now, they would find that they were not the only ones who felt that they couldn't keep up with each other's rhythm.

"Let's skip that conversation." In this situation, Yu Gui wisely proposed a solution.

Yan Shu agreed deeply and nodded vigorously.

"Then you continue to read, and I'll review." Yu Gui took out his courseware and notebook at this time and said.

Yan Shu glanced at his courseware with some curiosity, and saw that the first title page read "Quantitative Finance: Modeling and Computing", and his eyes couldn't help but show a look of interest.

"You're going to take an exam?" He asked.

"Well, next Tuesday." Yu Gui subconsciously rubbed his eyebrows with his fingers and said, "I haven't learned this course very well, so I have to hurry up." ”

"What don't you understand? I just happened to have taken this course, if you have something unclear, maybe I can know some more to help you sort out your thinking. Yan Shu said quickly.

Yu Gui couldn't help but look up at him: "You also learn this?" ”

"I learned it before, I don't know how much I remember now." Yan Shu touched his ears, and then he stood up and walked to Yu Gui's side and sat down, looking very sincere to answer people's questions.

Yu Gui didn't expect Yan Shu to be so active, and he didn't even have time to say anything about resignation.

However, he thought about it at this time, Yan Shu is also a graduate student, and his knowledge reserve must be stronger than his own, and it should be very helpful to discuss problems with him, so he no longer refused.

In order to sort out his thoughts, Yan Shu had already picked up his courseware and went through it roughly, and after reading it, he frowned slightly and said thoughtfully: "If every lecture of this professor is in the same teaching style as this handout, then it is no wonder that you have something you don't understand." It's not just you, I suspect there aren't many people in your class who can figure it out. ”

"Why do you say that?" Yan Shu said very surely, and Yu Gui couldn't help but be a little surprised.

The professor in charge of this course is a well-known consultant on Wall Street, who has used quantitative modeling methods to deal with all kinds of large and small transactions, and his method has even become a system of its own, and is quite famous in the industry. However, although this person is very good at practical operation, he is not very good at lecturing, and his lectures often make people feel like they are falling into a fog.

However, despite this, because his prestige is there, there are still many people who choose his course, even though they know that they will not understand, on the one hand, hoping that they can suddenly comprehend some essential thoughts, and on the other hand, they also want to have a good relationship with the professor himself. If you have the opportunity to get a letter of recommendation from him, it will be much easier to get into the big companies on Wall Street in the future.

Yu Gui chose courses with these two purposes in mind.

"This professor of yours should belong to the type who has a lot of practical experience, but has not studied too deeply in teaching."

Yan Shu's expression became inexplicably serious when he held the handout, and Yu Gui looked at him and waited for a moment before he said with certainty: "He is very good at actual combat, he has been in Da Mo, Citigroup, and UBS before, and now he is in Goldman Sachs." However, this is the second time he has taken this course. ”

Yan Shu showed such an expression after hearing this: "No wonder, people with pure practical experience are prone to make similar mistakes when they give lectures, there are many basic concepts that he will take for granted and briefly mention, and some don't even mention them, this method may be feasible for graduate students or doctoral students, but it is more difficult for undergraduates to understand." For you, it is important to have a solid grasp of the most basic concepts and ways of thinking now, otherwise you will feel overwhelmed when you learn more deeply in the future. ”

Yu Gui listened to what he said, and he obviously felt that it made sense, but he couldn't help but want to laugh: "Why did your painting style suddenly change?" ”

"Painting style?" Yan Shu was stunned at first, and then there was a cramped and slightly nervous look on his face that Yu Gui was familiar with, and said, "I haven't changed, I've always been like this......"

"Well, it's back now." Yu Gui quipped.

Yan Shu's face flushed, and he lowered his head before saying, "We, let's take a look at the courseware...... Where are you not clear? ”

Yu Gui couldn't bear to continue teasing him when he saw him, so he restrained his joking look and began to look at the courseware seriously, marking what he didn't understand and then asking Yan Shu.

In fact, Yu Gui has learned very well, and there are not many things he doesn't understand, but he found that after Yan Shu told him, he had a deeper understanding of other concepts, which was very touchable.

And originally Yu Gui didn't think about how powerful Yan Shu was, but when he saw the real chapter as soon as he started explaining, the level was definitely not low.

It's not good that Yan Shu is actually a doctor, I thought he was a graduate student and underestimated other people's academic qualifications, so I thought silently.

"Yu Gui, do you have any other questions?" Yan Shu was very efficient, and after a while, he finished talking about what he wanted to ask.

"Not yet." Yu Gui was still staring at the courseware and savoring it, and the knowledge in his mind felt really good, as if the second pulse of the martial arts practitioner was suddenly opened.

Hearing that Yu Gui had no questions to ask for the time being, Yan Shu's radiant expression when he was explaining just now faded a little, and he looked like he wanted to say something more.

Yu Gui remembered the few times he had met before, whenever Yan Shu showed this kind of expression, he would forcibly stop the topic, and he was a little reluctant to go, so he rarely said: "Say what you want to say, don't hold back." ”

"Huh?" Yan Shu's eyes lit up several tiles in an instant, and the two fingers of his right hand subconsciously touched the root of his ear, and said happily: "I want to tell you, if you have any questions about this in the future, you can call me at any time to ask, or if we are all in school, we can also come to the library together." ”

I don't know if it's my own delusion, Yu Gui felt like he was invited on a date when he heard Yan Shu say "come to the library together".

Is he too sensitive?

Or is it Yan Shu, it really has to be ......

"Yan Shu," he was entangled in this matter, and Yu Gui's tone sank unconsciously, and this voice made him feel too strict even when he heard it.

Yan Shu was obviously a little unclear, so he stared at him fixedly and moved his lips, but he didn't dare to make a sound.

After realizing the problem with his tone, Yu Gui quickly corrected it, and when he spoke again, he had already reverted to a normal, friendly voice: "Actually, it's nothing, I wanted to say something to you just now, but I suddenly forgot about it." ”

"Yu Gui, do you want to tell me something very formal?" Yan Shu didn't seem to be so easily fooled, and still stared at Yu Gui and asked, "What does it have to do with it?" ”

"I really can't remember it now, but it's not a serious matter, and I'll tell you when I think about it." Yu Gui then diverted the topic and said that he wanted to continue to review, Yan Shu stopped bothering him when he saw this, and sat quietly reading a book.

At this time, if someone saw the two of them, they would definitely feel that the peaceful and stable atmosphere between them was very harmonious.

However, this kind of harmony may only exist on the surface.

※

On the morning of the following Tuesday, after Yu Gui finished the quantitative finance course, he felt a lot more relaxed and in a good mood.

Under such conditions, when Mai Qixian proposed to let Yu Gui accompany him to class, Yu Gui agreed, and it was not good to disappoint his friends all the time.

The place where the class was held was still in the business school, on the third floor of the uris, and Mak Qixian dragged Yu Gui all the way to the brisk walk, and arrived at the classroom when there were still fifteen minutes before the class.

"What's the hurry," Yu Gui sat down and looked at the panting person next to him and couldn't help but say, "This classroom is still empty, and I'm not afraid that I won't be able to occupy a seat." ”

"You don't understand!" Mak Qixian put his elbow on his shoulder and gasped: "Most of the people who take this class still have a class, so it will take a while for them to come over after class, so we just have to pick up this time difference." If you don't believe it, if it's a minute or two late, it's overcrowded! ”

Yu Gui smiled noncommittally when he heard what he said, but he didn't realize that just a minute later, a large number of students poured in at the door of the classroom, and in the blink of an eye, the whole classroom was already full.

"How? Dude didn't lie to you, did he? Seeing this scene, Mak Qixian couldn't help but hug Yu Gui proudly and smiled.

"It seems to be really popular." Yu Gui nodded and said.

Mak Qixian listened to it: "That's not it! I called you to come before, but you still haven't come! I sue you, after this class today, I will make your kid regret that his intestines are blue! ”

"Let's wait until I'm done listening to a class--" Yu Gui's last word "bar" was suddenly covered by Mak Qixian with his hand before he could say anything, and he couldn't help but stare at Mak Qixian a little depressed before he could understand what was going on.

However, Mai Qixian didn't care about talking to Yu Gui at this time, his eyes stared directly at the person in front of him, his eyes were round, and his mouth was open so much that the boss kept muttering: "...... Groove ...... Groove !! ”

Yu Gui followed his gaze and only saw the back of a boy with a half-length dark brown ponytail, but he didn't know it.

"What's wrong with you, what the hell?" Yu Gui finally pulled Mai Qixian's hand off his mouth and asked helplessly.

And Mai Qixian stared at the back for about ten seconds before turning his head and looking at Yu Gui in disbelief and said, "Almost...... Do you know who I saw? ”

Yu Gui shook his head, but just as he was about to ask who it was, he suddenly remembered what Mak Qixian told him not long ago.

"Hey, could that be ......" Yu Gui was stunned, thinking if it should be such a coincidence.

But Mak Kai-yin's next answer confirmed his conjecture.

"That's right, it's the bastard who slept with Lao Tzu last time and played with geese without a trace! I've been looking for him for a long time! Mak Qixian said with murderous eyes in his eyes.
