When they got downstairs to the apartment, Gu Xing got out of the car first. He didn't take two steps, and his figure became a little unstable, and Cosine quickly stepped forward to support his arm.

After drinking too much wine, Gu Xing's stomach turned upside down, the fire burned, and he vomited all the dinner he had eaten as soon as he got back to the apartment.

After vomiting, the others collapsed, leaning on the sink with a pale face.

Cosine handed him the wet towel, "Wipe it."

Gu Xing took the towel and wiped it on his face casually. He looked at Cosine's face under the light and suddenly smiled, "Mr. Yu, are you so nice to every student?"

Cosine shrugged and said helplessly, "To be honest, I just want to go back to the teacher's apartment to sleep."

Gu Xing laughed, "I can see that, if you don't dislike it, then you can go to my place and sleep in the master bedroom."

Cosine was not polite to him, anyway, he had taken a shower before, and it would be fine for one night here.

Gu Xing looked carefree, but the bedroom was quite clean. Cosine was already tired, and almost fell asleep on the bed.

In the morning, he slept until he woke up naturally, almost as soon as he opened his eyes, he felt a line of sight staring at him beside the bed.

He was startled, and when he saw that it was Gu Xing, he breathed a sigh of relief.

Gu Xing was wearing a black T-shirt and dark green overalls, looking much better than yesterday.

"Mr. Yu, I found that you look pretty good if you don't wear glasses."

Gu Xing himself is handsome and handsome. In his eyes, the only criterion for good looks is Shen Mang, and "not bad" belongs to his extremely high evaluation of appearance.

Cosine didn't know how long Gu Xing stood here and stared at him, but a strange feeling flashed in his heart, and he quickly grabbed the glasses by the bedside and put them on.

"No, I look ordinary."

"I'm serious."

Gu Xing suddenly got closer, staring at his facial features carefully.

"Your glasses are too dirty, just change them. You have to cut your hair too, it will definitely change your look."

As soon as he finished speaking, someone pinched the back of his neck, and Cosine pulled him away with a look of disgust.

"Student Gu, is this the attitude you should have when talking to the teacher?"

Gu Xing stuck out his tongue and slipped away from his hand like a loach. Cosine looked at the time and remembered that he had to invigilate the exam today, so he hurriedly got out of bed and put on his shoes.

He sorted out his wrinkled shirt as he walked towards the living room.

"Remember to take the exam on time in the afternoon, don't be late."

Gu Xing took out a box of yogurt from the refrigerator and turned to look at him, "Aren't you staying for breakfast?"

"No, I'll go to the cafeteria to eat."

Gu Xing clicked his tongue, his tone disgusting, "What's so good about the cafeteria, it's so unpalatable to death."

"Young master, of course you don't like the school cafeteria."

Cosine was about to reach the door, and his footsteps suddenly stopped. He just saw a group photo on the TV cabinet. Gu Xing in the photo is still a little beanie, black and thin. Standing beside him was a very beautiful and handsome young man.

This boy's facial features are very similar to Shen Mang.

Could there be such a coincidence... Cosine seemed to have some clues in his mind, until the sudden ringing of the mobile phone interrupted his thoughts.

"Mr. Yu, the exam preparation meeting will start soon, haven't you come yet?"

"I'm on my way, I'll be there soon."

After a whole day of invigilation, Cosine received an invitation to attend an academic salon at a university in the city center in the evening. Originally, he didn't want to go, but several teachers in the same subject group had to take care of the family and couldn't get away, so he, the only single person, had to bite the bullet.

Cosine has always been a dislike of social interaction. After entering the venue and signing in, he took a package of snacks and silently found a corner to sit down. However, the weather was unsatisfactory. Not long after he sat down, there was a gentle-looking man in his early thirties. The man came over.

"Are you a new teacher from HKUST? I don't seem to have seen it before."

The man wore a decent suit and shirt, with a strong cologne scent on his body, his hair was all combed back, and he showed a rather confident smile.

"I'm from T University. I was promoted to associate professor last year. Would you mind getting to know me?"

T University is a well-known key university in the country. He can be promoted to associate professor in his early thirties. This person does have the capital of self-confidence.

If it's just a simple friendship, that's all, but the desire and playfulness in the man's eyes is obviously not the case.

In the academic circle, there are those who devote themselves to research and do not ask for fame and fortune. Naturally, there are also those who seek fame and fortune. Cosine put down the plate in his hand and glanced at him up and down.

The man thought he was interested in him, and subconsciously raised his chest and stood straighter.

"Sorry, I don't like bald ones."

man in suit:  …

His wig is obviously very hidden, how did this person see it?

"Also, the ring mark on your ring finger has not disappeared. As a teacher of the people, is it not good to do such a corrupt teacher's morality?"

The man was holding the wine glass in his hand, and his face became extremely bad.

The anger and shame that were exposed came up together, he glanced at the nameplate on Cosine's chest, and said meanly, "Do you think I really like you? What kind of lecturer at Yeji University, dressed like a bumpkin, in this life Has anyone ever approached you?"

Cosine nodded and agreed, "Well, only the dog has chatted with me."

The man in the suit looked like he was about to faint, he twitched the corners of his mouth, finally squeezed out a twisted smile, and turned away.

Cosine breathed a sigh of relief, he finished the snack and left the venue early.

There was a bookstore nearby, and Cosine just wanted to buy a book, so he pushed the door and went in for a stroll. He couldn't stop when he read the book, and read it for several hours. It was not until the bookstore closed that he was content with the newly bought book and entered the subway station.

When went back to school, took the last bus, and the moment stepped into the door, Cosine had a faint feeling of a chill on back.
