New York City, One Hundred and Sixteenth Street on Manhattan's Upper West Side, is home to one of the oldest Ivy League schools, Columbia University.

It's 7:28 a.m.

At this time on Friday, there were hardly many people on campus, and it seemed very clean.

Yu Gui had just walked into the school gate at this time, and he walked towards the teaching building with a schoolbag on one shoulder, but was stopped when he passed in front of the administrative building.

"Classmate, can you excuse me, do you know how to get to the uris building?"

The interviewer was a young Asian man with tall stature, well-rounded features, and a warm voice that sounded elegant in standard British English.

Yu Gui stopped, raised his hand and pointed to him: "Go back from here, the building directly behind is." ”

"Thank you, and have a nice day." The man thanked him politely, and looked like he wanted to say something.

However, Yu Gui had no intention of chatting, "Thank you, you too." With that, he turned around and walked away from the other side of the administration building.

In fact, the place where Yu Gui was going to take classes was in what this person called the 'uris building', but in order to avoid being with him, Yu Gui deliberately quickened his pace and entered the building before that person.

After arriving at the classroom, Yu Gui picked a position in the middle row by the aisle and sat down, took out the handouts and put them next to him to occupy a seat for his friends, and turned up the book himself.

"Option pricing model ......" Yu Gui said silently as he watched, this was what they talked about in the last lesson, and he wanted to review it before starting a new class.

"Binary Tree...... ...... is now worth it" Yu Gui held the book and read it intently, and suddenly realized that there was suddenly another person beside him, until the man slapped him on the back and he suddenly sat up straight.

"You're looking for death again, aren't you?" He cast an oppressive look at the comer.

But the boy, who was at least 1.84 meters tall but had a baby face, smiled and hit him with his crotch and said, "You haven't noticed that I've been standing here for a long time, so you can't blame me for scaring you, right?" Let me in, let me in! ”

Yu Gui sat still, still glaring at him: "Aren't you capable, think of yourself to go in." ”

"Are you sure?" The man raised his eyebrows and asked, "Then why don't I step over you?" Crotch?? ”

"......" Yu Guihuo stood up and stepped out of the way: "Speed." ”

"Order!" The man happily swaggered inside, then sat on the stool next to Yu Gui, turned around and smiled at him: "Dude, don't stand, come and sit." ”

"Mak Qixian, you didn't take your medicine this morning, right?" Yu Gui sat down and glanced at the baby face lightly, and suddenly wanted to try what it would be like to slap it, it must be very cool.

However, Mai Qixian seemed quite happy when he heard Yu Gui's words, and came up and said, "How do you know? Eh, I'll be honest! Did you steal my medicine? I said, how can I see that the bottle is empty this morning! ”

"Shut up or disappear."

"It's almost class, and I can't disappear." Mai Qixian stared at Yu Gui with a smile on his head with his hands, and suddenly his eyes flashed to the side, and he touched Yu Gui with his thigh under the table and said, "Look! Dani is coming to you again! ”

Yu Gui originally didn't want to pay attention to him, but when he heard the latter sentence, he raised his head, and it happened that Wu Danni had just walked up to the two of them at this time.

"Yu Gui, there is a job as a translator this Saturday night, do you want to take it?" Wu Danni gently shook her big waves that were very delicately hot as she spoke, her electric eyes blinked, and the color of her lips was very beautiful.

"What's the price?" Yu Gui looked at her and asked.

Wu Danni stretched out a finger and shook it: "A hundred dollars an hour, how about it?" ”

"Well, I'll take it." Yu Gui nodded.

"Then it's decided! See you tomorrow night at seven o'clock sharp, in front of Caesars Atlantic City! It is estimated that it will take a lot of time on the road, so make sure you don't get late. Wu Danni clapped her hands and smiled.

At this time, Mai Qixian, who was sitting next to him, couldn't help but interject: "Hey Dani, can you introduce me to a few jobs if you have such a good job in the future?" Don't always be cheaper, Yu Gui, this kid, can't grow too biased! ”

"Phew!" Wu Danni poked Mak Qixian's forehead with a finger: "Are you short of money?" What does Yu Gui have to do with you, you eat his jealousy, do you still have a conscience! ”

"Don't, don't! I'm kidding! Mai Qixian was very hurt by that poke, he kept rubbing it with his hand, and with the other hand, he grabbed Yu Gui's shoulder and said: "Actually, I'm not worried that my brother is working too hard, he usually rushes homework and papers every day, and he can't rest well on weekends, look at how thin this child has become!" When I first met him in my freshman year, he was so much more fleshy than he is now! ”

As if to prove his point, Mak Qixian rested his head on Yu Gui's shoulder and rubbed his head twice, and then sighed, "Oh, hey, what a diaphragm!" ”

Yu Gui glared at him sideways, and didn't want to talk to him anymore, so he only said to Wu Danni, "Danni, thank you." ”

"Don't be polite to me, we don't need to be between the two!" Wu Danni playfully stuck her tongue out at him, and flicked a finger on Mak Kai Yin's head before turning to find her own seat.

At this time, the professor had just entered the classroom, and the teaching assistant began to distribute the handouts this time, and Mak Qixian couldn't help but whisper that the business school was really wealthy, and the handouts never had to be printed by the students themselves.

Yu Gui didn't answer when he heard it, this is not the first time he has said this, and it is estimated that it will not be the last, if he doesn't have to annoy himself to death every time.

Finally, when class started, Mak Qixian quieted down.

Their course is called "Introduction to Financial Derivatives and Pricing Model", and the professor in his fifties gave a wonderful lecture, and the hour and a half passed quickly.

"Eh, brother, it's okay later, let's go to the uris library together?"

After class, Mak Qixian asked Yu Gui to go to self-study, and Yu Gui asked him to occupy a seat first, and he planned to go to the bathroom.

"Then I'll withdraw first, it should still be the old place, you enter the door and turn right to find me!"

"Well, I'll see you later."

Yu Gui packed up his things and walked to the bathroom on this floor, seeing that there were not many people in the building today, and the corridors were empty, but when he stepped into the bathroom door with his front foot, he followed with one. Yu Gui subconsciously didn't let go of the door for the person behind him, but he heard a familiar voice say to him, "Thank you." ”

Yu Gui looked back and saw that it was the Asian man he had met in the morning.

"Huh? See you again! The man was also a little surprised when he recognized him, and then smiled brightly at him and said, "So you are also taking classes here!" ”

"Hmm." Yu Gui is now in a hurry to free his bladder and has no intention of talking to him, secretly thinking that this person wants to talk to him without picking a better time, and he is helpless.

"That--"

Seeing that this person was about to speak again, Yu Gui made a rather embarrassed expression and pointed to an empty compartment next to him and said, "I'm sorry, I ......"

Seeing this, this person suddenly realized, and waved his hand again and again: "I'm sorry, I'm sorry it's my fault, you can go quickly......"

"Good ......" Yu Guiyi flashed into the cubicle, and after closing the door, he thought that the embarrassed expression on the man's face just now was quite funny.

However, even if he felt that the man was amused, he had no intention of talking to him further.

Hearing him enter another cubicle, Yu Gui quickly solved his problem, then pulled on the zipper, washed his hands, pulled two pieces of toilet paper and went out of the door.

After all, chatting with strangers in the toilet is really not his hobby.

……

"Return! Here! ”

After entering the library, Yu Gui saw that Mak Qixian had already found a place, so he walked over with his schoolbag and sat beside him.

"Eh, let me tell you, Dani came in just now, and when she saw me, she asked me where you were! You said our Miss Dani was so attentive to you, didn't you—" Mak said with a smirk in a low voice.

Yu Gui glanced at him lightly: "Don't talk about these unreliable, Dani knows about the two of us, and you don't know Dani's situation." ”

"I know!" Mak Qixian blinked slyly, "That's why I feel more dramatic!" You said you both bent and straightened yourself for each other! Multi-sensory !! ”

"You're sick. Why don't you write a novel if you have this brain? Yu Gui took out his computer and said angrily while turning it on.

Mak Qixian let out a long sigh, put his arms on the table and held his face with both hands, looking like a young girl, with a rippling expression: "I want to write, but it's a pity, it's a pity......"

"What a pity." Yu Gui's reason told him that he should never ignore him at such a time, but he still couldn't help but ask.

Sure enough, I saw that Mai Qixian instantly showed a shyness smile, and exaggeratedly shook his hands and said, "It's a pity that I have too many talents!" Writing is just one of the less impressive ones, and I'm going to spend my time developing more meaningful talents! For example, my looks! ”

“……”

Yu Gui silently put on the headphones, and then said, "Don't listen to you being poor, I want to prepare the courseware for tutoring on Sunday." ”

"Whew......" Mak Qixian replied reluctantly, muttering, "Brother, I really think you're too tired of making yourself." ”

After he finished speaking, he didn't hear Yu Gui's reply for a long time.

Mai Qixian thought that Yu Gui turned on the music and didn't hear what he said, so he sighed helplessly, and took out the headphones from his pocket and prepared to listen to the song.

However, at the moment before he pressed the play button, Mak Qixian heard Yu Gui's slightly tired bass beside him.

"Maizi, I don't have a choice."
