After the lunch break at noon, Cosine went to the lecture hall in advance to try the recording and broadcasting equipment. After confirming that there was no problem, he took the USB flash drive and planned to go back to the office. As soon as he walked to the door, he met the principal who was visiting the hall in the afternoon.

"Is Teacher Yu testing the equipment?"

The principal was grey-haired and known for his gentle character. He is more concerned with teachers' teaching ability than teachers' scientific research. So when have time, will go around the hall.

Cosine had seen him several times. He thought that the principal would not have any impression of him, but he didn't expect the other party to remember his name.

"Yes, Principal Peng."

"You are very popular with students now. Even students from nearby schools want to come to your class."

Cosine smiled a little embarrassedly, "I don't have much experience, so maybe my teaching isn't very good."

"Mr. Yu, you have such a big influence now. In fact, you shouldn't limit your courses to classrooms. The subject of psychology should be known by more people. I think some Internet celebrity teachers have opened Weibo accounts. If you want Don't you get one too?"

Cosine didn't expect the principal to say such a thing to him. He didn't want to open a Weibo account before, because he felt that there were too many disputes on the Internet, and he was afraid of being disturbed, but he forgot that his identity was a teacher.

As a teacher, it is also his responsibility to preach and teach and solve puzzles, so that more people can understand the charm of the discipline of psychology.

"Principal Peng, I understand. I will register an account when I go back tonight. I will also post the video of the class in the future."

"That's great, Mr. Yu. There are a lot of students with psychological problems now. I'd like to ask you to help with the work at the psychological counseling center."

"it is good."

Before class time, the huge lecture hall was full of people. When Cosine's figure appeared in the classroom, there was a huge noise.

Cosine is standing in the center of the podium today, wearing a well-cut beige shirt and black trousers.

He has a clean and gentle temperament, with a faint smile on his handsome face, looking at the students in the classroom.

He stood there without speaking, and the classroom quickly became quiet, and the young students all looked at him with burning eyes.

"I know that some of my classmates may have never listened to my class, and decided to take this class only after watching the variety show I participated in."

"Exactly, the theme of today's class is love. I participated in another love variety show. I don't think anyone is more suitable for this class than me."

There was a tacit laughter from below.

Cosine didn't talk nonsense, and quickly introduced the topic, "You are all college students in your twenties. At this age, you should be most concerned about how to get along with the opposite sex and how to find someone you love. There will definitely be many people who are confused. Is there perfect love in real life? What exactly is love?"

"Sternberg, a professor of psychology at Yale University in the United States, proposed the triangular theory of love. He believes that all love experiences are composed of three elements: passion, intimacy and commitment. Only when these three are present can it be called perfect. love..."

Many students sitting in the front row opened their mouths wide, looking at Cosine who was standing on the podium talking in surprise.

To be honest, they chose this course just because they wanted to see the handsome guy, and they didn't expect the other party's class to be good at all. After all, before they went to college, they heard the senior and senior sister say that many college teachers read according to the PPT in class, and they are too lazy to care whether the students listen or not. They are numb and rigid, and have no emotions.

I thought Cosine was so handsome, and I was busy participating in variety shows, so I guess I didn't spend much time preparing for lessons. I didn't expect his class to be so good, and the boring psychological theories became lively and interesting when he taught.

Some students couldn't help but took out their mobile phones and secretly started recording the screen.

Cosine turned a page of PPT, he noticed the student's movements, and the corner of his mouth tickled.

"If you want to revisit this class, I will record every class and upload it online. There is no need to record the screen with a mobile phone, which will affect the order of the class."

Only then did the student realize that Cosine was talking about him, he blushed and put the phone back in the drawer in embarrassment.

Ten minutes before the end of the course, there is free question time.

Many people raised their hands high and wanted to ask Cosine a question. Cosine asked the teaching assistant to pass the microphone to a girl in the back row.

The girl was so excited when she received the phone, she looked at him with glowing eyes, "Mr. Yu, I want to ask, do you believe there is the kind of perfect love described by Sternberg in this world?"

Cosine smiled, "Of course I believe it."

"Teacher Yu, do you think you have met this kind of love?"

As soon as this question came out, all the students looked at Cosine excitedly, with the desire to gossip in their eyes.

Cosine thought for a while, and when he was about to answer, he suddenly saw a figure beside the window in the corridor.

It turned out to be Kong Mingyu. Wearing a light-colored shirt with a smile on his face, he stood waiting for him outside the classroom.

Some students followed his gaze and saw Kong Mingyu standing outside the classroom, and immediately became excited.

Several students were CP fans of Kong Mingyu and Cosine. Seeing this, they hurriedly said, "Mr. Yu, I heard that Dr. Kong also has a double degree in psychology. Would you like him to come in and talk?"

"Yes, Mr. Yu, Dr. Kong is a doctor of Jiang University."

Being disturbed by the students, Cosine had no choice but to open the door and go outside to find Kong Mingyu.

"I still have ten minutes to finish class, why are you here so early?"

"I haven't listened to your class. I want to come and see what it's like."

"My students are all clamoring to listen to your lecture. Come in, Dr. Kong Da."

Kong Mingyu didn't refuse and walked in with a smile. He raised his palm and pressed it down, signaling the boiling students to keep quiet.

"I heard from Teacher Yu just now that it is free time for questions. Let me help him answer two psychology-related questions. You can ask me."
