After Zhao Bai'an tossed and turned many times, he opened his eyes a little helplessly, and the light in the bedroom had been turned off by Yang Liuyi.

There was darkness all around, Zhao Bai'an was bored, his eyes wandered at will, and in the end he could only fall on the gentle and amorous moonlight that was ruthlessly cut off by the curtain cloth.

She couldn't help but have a thought in her mind, what is Chen Yudi doing now? She always unintentionally remembered what it would be like to study with Chen Yudi every day from now on.

Her brain seems to be uncontrollable for unwarranted speculation, in fact, it is because of the expectation in her heart that time flies a little slowly. As now, she had inadvertently begun to pray, hoping that the moonlight would soon change to daylight.

"Tower, da-da." The footsteps outside the door sounded, and Zhao Bai'an knew in his heart what the voice meant, it must be the dormitory aunt Cha Qin who came.

She closed her eyes again, and as she had guessed, the door to her dorm room slowly opened, as she had guessed. After a week of inspection, the dormitory manager quietly left, leaving only silence and darkness.

Normally, Zhao Baian wouldn't care too much, but today because of insomnia, she listened to the footsteps very clearly.

After the dormitory manager left, Zhao Baian began to toss and turn on the bed again, and after a long time, she finally quieted down.

The sound of even breathing in the dormitory, accompanied by the night, is like a sound of music, beautiful and graceful.

Zhao Bai'an slept extremely peacefully tonight, waking up after only a dream of playing the merry-go-round on Hearts Island, and when she opened her eyes, it was already as bright as she expected.

After Zhao Bai'an woke up, he looked at the chaotic and busy scene in the bedroom, and suddenly changed from a holiday state to a normal state.

She also hurriedly got out of bed, and after tidying up, hurried to the classroom. After more than three hours of class, when it was close to noon, Zhao Baian finally dragged his tired body out of the class.

Chen Yudi was waiting for her at the door of the classroom, and she looked up to see Chen Yudi greeting with a smile: "Yudi, why are you here?" ”

Chen Yudi held the student card in her hand, shook it twice in front of her, and then smiled and said, "What's wrong Bai An?" Can't I come? Have you forgotten what you promised me? ”

Zhao Bai'an was in discrete mathematics this morning, and it happened that the whole class was a test of memory, and the teacher kept checking the various knowledge points that she had talked about in the last class, so she was a little confused at this time.

Chen Yudi looked very relaxed, and the state of the two seemed to be slightly different. Zhao Bai'an reacted immediately after Chen Yudi's reminder, and hurriedly responded to Chen Yudi: "I'...... Who said forgot? I haven't forgotten, don't you see my student ID card is also here? ”

Zhao Bai'an was a little weak when she said this, because she knew that her student ID would be in her pocket as long as she was in class.

So it's a bit unfair to talk about this, but she doesn't care, anyway, Chen Yudi doesn't know about it, so as long as she doesn't show anything wrong, no one knows what she's thinking.

Chen Yudi still had a sunny smile like that, and reminded Zhao Bai'an in a gentle tone: "Then let's go!" ”

The two of them walked towards the study room together, and after coming to the study room, because they had to swipe their student cards, the two of them split up and lined up to enter in turn.

After coming in, Zhao Bai'an was surprised by the environment inside, she didn't come here often before, so she didn't have much impression.

But this time, she was impressed, this place is quiet, even depressing.

Everyone in the lobby looked down and read to themselves, and all of them maintained one position, as if she was back in the classroom of elementary school students.

She secretly screamed in her heart, and then secretly glanced at Chen Yudi.

Chen Yudi's face was happy, all his expressions were shown on his face, Zhao Bai'an really didn't know that Chen Yudi could actually laugh all the way to the root of his ears.

Of course, this description is a bit exaggerated, just to express Chen Yudi's extremely satisfied mood.

Because Chen Yudi had already tried to make an appointment yesterday, they were not in the lobby, but were able to go to a separate room. The door of the room is transparent, and the sound insulation of the wall is good, this time Zhao Baian has a little impression of this, which is very similar to the room where she met Yang Zichen before.

The two of them found a seat in the room and sat down, and then each took out the book prepared in advance from his school bag.

Chen Yudi began to study seriously, but Zhao Baian seemed a little absent-minded.

She actually wants to perform well, strive to leave a good impression in front of Chen Yudi, and score a perfect score.

But there will always be a big gap between imagination and reality, because Zhao Bai'an is carrying all math books in her schoolbag, and she is always not easy to understand particularly abstract concepts, so she is really afraid of something.

She looked at the dense questions, and began to be stunned in her heart, not to mention studying seriously, even if it was a little difficult to read it.

But in such an environment, she couldn't stand up or do anything else.

Zhao Bai'an suddenly had a feeling of sleepiness, she was a little helpless, she shouldn't have made a sound, but she still couldn't help but sigh: "Alas......"

This sigh is harmless, but because of the quietness here, it is extraordinarily loud and empty.

Chen Yudi glanced up at Zhao Bai'an, as if it had interrupted his train of thought, so he looked very serious.

Zhao Baian hurriedly smiled embarrassedly at him, then waved his hand and continued to bow his head and chew the book.

After that moment just now, she learned a lesson, and she didn't dare to make a sound anymore, although it was uncomfortable to look at the question, but she stood up there.

Standing up, Zhao Bai'an began to break out in a cold sweat, and Chen Yudi, who had finished thinking, noticed her next to her.

Originally sitting opposite him, Chen Yudi got up and adjusted from the opposite position to the position next to Zhao Bai'an.

He took the math book in Zhao Bai'an's hand, and at the same time took out a piece of calculus paper from his pocket.

"This question?" He asked in a particularly low voice, as if he was afraid that the sound would reach the very quiet hall outside and disturb the other students.

Zhao Bai'an nodded knowingly, and then Chen Yudi looked at the book and read the question carefully, and after thinking for a while, he began to divide the problem on the top of the calculation paper, divided the answer and steps into two pieces to write, and added annotations on the side.

After he had done all this, he pushed the book and the answer back to Zhao Bai'an's side.

Zhao Bai'an was still confused just now, and when she saw what Chen Yudi wrote, she immediately showed joy, she had to admit that Chen Yudi at this moment was definitely her Guanyin Bodhisattva who saved suffering.

A complex question has become so simple in his hands, and the most important thing is that he analyzes the topic very clearly. Although the writing is a little more elegant, it does not hinder Zhao Bai'an's understanding.

Zhao Baian only needs to read it carefully to thoroughly understand the topic, which is a dream she can't even imagine.

She patted Chen Yudi on the shoulder, and then said a "thank you" with her mouth.

Chen Yudi looked at her and smiled, then returned to his seat and lowered his head again to continue to bury his head in calculations, while Zhao Baian continued to slowly do his own exercises.

Every day after that, as long as the two of them have time, they will meet together to come to the study room.

After a long time, Zhao Baian slowly began to understand Chen Yudi.
