It was the voice of that short-haired girl who told her to clean up the dormitory when she woke up yesterday, what's her name? After searching through her memory, Ah, it's Liu Jia.

  "You'd better be more tactful, who knows what kind of difficulties they might have at home? What if their family is going bankrupt? They can't just throw away the clothes and handbags they bought before, can they?"

  I heard that this was probably the voice of that star-chasing girl, named Zhao Tian, a sweet and lovely little pepper, with a pretty face and not a bad person, just a bit poisonous mouth.

  Liu Jia listened to Zhao Tian's words, thought for a moment, and didn't refute: "What you said is also possible. If it's like that, then I really misunderstood her. When she comes back, I'll ask her. If I really misunderstood her, I'll apologize to her!"

  "Alright, after we've figured things out, let's go out for dinner tonight and I'll treat. Our dorm hasn't had a proper gathering yet."

  It must be Zhou Wei, her last roommate. From the original owner's memory, this is a genuine rich second generation, unlike her fake thousand gold. Her daily wear is all private high-end brands, and her family background is estimated to be much better than that of the idle household.

  There was no need to listen anymore, she took out the key and opened the door, pushing it open directly.

  The three roommates heard the noise and all turned their heads to look at her.

  Suddenly received attention, and was stunned for a moment.

  Before she could put down her things, Liu Jia rushed over and pulled her down into a chair. The three of them all had serious faces on, the trial was indeed about to begin.

  Why should I be afraid of being scolded when I have nothing to lose? My face remains expressionless, and I remain calm.

  Of the three people, Zhao Tian's personality was the most urgent. Seeing Liu Jia hesitating to speak, she couldn't help but ask first: "Xianyu, is your family condition not very good?"

  Zhou Mei rolled her eyes at Zhao Tian's question, which she thought was quite impolite. Was it really good to pry into others' family backgrounds so openly? Couldn't they be more tactful about it?

  To avoid damaging the dormitory relationship, Zhou Mei had to add: "Don't get me wrong, we didn't mean to pry into your family affairs. It's just that you usually don't seem to eat well and we're worried about your health, so we care about you."

  Wei Zhou Mei finished speaking, Zhao Tian herself also realized she was too direct and hurriedly explained: "Right right right, we're just concerned about you, don't misunderstand, if there's any trouble just say it, maybe we can help."

  It seems that her three roommates are not bad-hearted people, she is still quite lucky.

  In college, I met several roommates who were easy to get along with, which is indeed a happy thing. After all, everyone will be together for four years, and harmonious coexistence is beneficial to physical and mental development.

  "Historical department's flower Su Lian knows, I and she are the relationship of true and fake thousand gold, she is real and I am fake." He said lightly.

  It's nothing shameful, just a bit embarrassing, there's nothing that can't be said, so I'll tell you the truth in my spare time.

  She didn't say anything more, but the remaining content was something that all three of them could fill in with their brains. This was clearly a case of the true daughter returning home and the fake one being swept out the door. It's even more melodramatic than the plot of "The Decline of the Family".

  No wonder they usually wear famous brands in their spare time, but eat so frugally.

  "I'm sorry!" Liu Jia's apology came in a timely manner.

  "I thought you were just spending your parents' hard-earned money to show off, sorry, I misunderstood you, I apologize." Liu Jia said with a bow.

  "It's nothing, just talk it out and it'll be fine." The calm and composed listener nodded in response.

  After all, Liu Jia's misunderstandings were directed at the original owner, and she had only been here for two days, without having much experience of Liu Jia's malicious words towards her. She didn't have the right to refuse Liu Jia's apology on behalf of the original owner.

  Now that the misunderstanding has been cleared up, the atmosphere in the dormitory suddenly became lively. Seeing this, Zhou Mei proposed again: "Since the misunderstanding has been resolved and our leisure time is back, I'll say it again, let's have a formal dinner outside tomorrow night, you guys decide on the location, I'll treat."

  It's very common for roommates in college to take turns treating each other to meals.

  He nodded slightly in agreement, then picked up his toiletries and went to wash up. Tomorrow was Monday, he had to get up early for class, so it was better to rest earlier.

  The other three had already washed up and now saw that You Yu was also washing up, so they all went to bed to prepare for sleep.

  Those who can get into a good university are all people who have squeezed through the narrow bridge of thousands of troops, learning has become an instinct, and going to bed early and getting up early is a must.

  Xianyu likes sunshine, so when she gets up in the morning and sees the beautiful sunny day outside, her mood also becomes beautiful.

  After hastily washing up, she and her roommate hurriedly went to the cafeteria for breakfast, laughing together.

  It's been a long time since she experienced such days.

  In her previous life, she was an orphan. Although she had grown up to be a pillar of the country, she inevitably had some introverted personality traits. Moreover, in order to become rich and famous, she devoted herself to scientific research and academia, treating the laboratory as her second dormitory during university, rarely having time to eat or go shopping with her roommates.

  Perhaps in this life she will still spend most of her time and energy on scientific research, but it's not bad to spare some mind to manage friendships and have more entertainment.

  When the four of them walked into the classroom, almost everyone had arrived. The front row was fully seated, so they could only go to the back row and sit down.

  This lesson is a higher math class, and I vaguely remember that the teacher was an old professor with the surname Sun from the mathematics department.

  Just then, a spirited and ruddy old man with a small stature strode onto the stage, apparently this was their advanced math teacher, Professor Sun.

  Look at this ruddy complexion! Professor Sun's life must be very comfortable and enjoyable! With some idle time, he strolled around absent-mindedly.

  "The girl in white clothes sitting at the back, yes, you, come on up here, you can receive today's gift."

  The girl in white clothes? Coming back to her senses, Xianyu glanced at herself and her roommate, it was fine, only she was wearing white clothes.

  Professor Sun has a well-known characteristic when teaching, every time he teaches, he likes to call on a student to come up and do a math problem as the start of the class, in some sense, this is also a kind of disguised roll-call.

  What about the classmates who were called up?

  If you can solve the problem, then it's fine, no harm done. If you can't solve it, then you're in for a treat. Not only do you have to accept Professor Sun's "love" baptism, but also face your classmates' sympathy and pity.

  Don't be fooled by Professor Sun's bright smile and benevolent appearance, he is actually extremely sharp-tongued, often able to make people feel ashamed without using any profanity, only feeling guilty for the Party and state's nurturing.

  Although Xianyu had never experienced it before, from her roommates' sympathetic eyes, she could already guess what they wanted to express.

  One sentence can summarize the essence.

  Someone once said that mathematics is the language of the universe, and this sentence is especially applicable to Yiyu.

  Even if it comes from different time and space, with different cultures and languages, there has never been any change in mathematics.

  Mathematical physics is the soul of scientific research, and it is also the foundation of scientific research. In my previous life, I was a big shot in science and engineering research, and mathematical physics was one of them. Although it may not be as good as others, it is still one of the best.

  So today I wasn't afraid at all.

  She walked up calmly, took out a piece of chalk and began writing rapidly. Her speed was so fast that it was clear at a glance how familiar she was with this knowledge.

  Three minutes later, Xianyu returned to his seat amidst the admiring gazes of his classmates.

  Professor Sun is somewhat depressed!

  He originally wanted to make things difficult for the girl sitting in the back who was still distracted, but unexpectedly, she was very capable and solved the difficult problem he set out in just a minute, making it impossible for him to find an excuse to make things difficult.

  He pretended to clear his throat and coughed awkwardly: "This classmate is quite good at math, I'm teaching this in my sophomore year, you can do it, it's obvious that you still like math, specially spent time studying it, how come you always sit in the back and daydream during class? This won't do, can't be proud just because of a little achievement."

  Professor Sun paused for a moment, then looked at the other three and said: "And what about those girls sitting next to her? There are already so few girls in this major, you're all precious talents. Can't you sit up front and let the teacher take a good look, refresh our eyes? The teacher is tired from teaching, can't you be considerate?"

  The boys: “………”

  We feel like you're scolding us, but we have no evidence.

  Noticing the gaze of the boys, Professor Sun got angry: "What are you looking at? Don't you know what you look like yourselves? Come on, who among you is still single, raise your hand and let me see which girl's eyes can't keep up with this old man."

  The boys: “………”

  We feel you're scolding us again, but we still have no evidence.

  Are they not interested in finding a girlfriend? Those who can get into Tsinghua University, don't they spend most of their time studying? High school is so busy, homework is piling up, and you still want to have an early romance? Are your parents' mixed doubles not painful enough for you? Not being bald is already doing justice to the country!

  When I got to college, there were only four girls in the whole class, with a male-to-female ratio of eight to one. Who dared to make a move? The first person to take action would definitely be beaten up by the other boys, right?

  Life is already so difficult, and yet teachers still have to expose their single status, this day can't be gotten through!

  "Teacher, teacher, they like your class so much that the front row was already full when we arrived." Zhao Tian hurriedly interjected, seeing that Professor Sun was about to continue.

  "Oh, I see, that's right, an ugly person should read more books." Professor Sun nodded, stroking his chin.

  The majority of boys: Alright, this time we have evidence.

  "It's no wonder you guys don't have girlfriends, every single one of you is a steel-straight man, can't even leave some space for the girls? Opportunities are created by oneself, you guys don't even have this bit of brain, and yet you still want to learn math?"

  Seeing the hopeless faces of the boys, Zhao Tian felt a bit embarrassed and wished she hadn't spoken up.

  Having dismissed them, Professor Sun finally began his lesson, and it seemed that everyone had finally breathed a sigh of relief.

  Two hours flew by, and the moment Professor Sun walked out of the classroom, Xian Yu was certain she heard a collective sigh from the boys and their lamentation that life was not worth living.

  Smiled and told my roommate, then went alone to the counselor's office.

  This morning there was only one class, she wanted to take this opportunity to ask her counselor how to minor in a second major.

  Arrived at the office, knocked on the door and went in. It happened that counselor Zeng Jing was on the phone, and it seemed like she was talking about some experiment or something.

  Do not look at what is not proper, do not listen to what is not proper. In spare time, take out your phone and browse Weibo to shift your attention.

  It seems that the original owner is quite fond of chasing stars, basically all the people she follows on Weibo are celebrities and artists, no wonder when she just woke up, her phone's push notifications were mostly celebrity gossip.
