"In the gradual autumn mirror, the dark changes the years".

Ling Yue stood at the mouth of the alley and heard the sound of crying mixed with the wind, he paused for a while, got on his bicycle and left the alley without looking back.

The next morning, Lin Yawen saw Teacher Lu calling Ling Yue and Mu Zi'an out, but soon after, they all entered the classroom one after the other. I don't know what Teacher Lu said to them, but the war between Mu Zi'an and Ling Yue seems to have ended after this heads-up.

"In the gradual autumn mirror, the dark changes the years". The tight autumn wind blows the fallen leaves on the trees, and also blows the stitches of time. After the turmoil, Ling Yue quickly returned to his original state: listening attentively in class, and writing and painting hard after class. Mu Zi'an still stepped on the bell of class, and walked into the classroom locally, but he had less time to sleep in class. As for when Ling Yue went to the blackboard to talk about the topic again, Mu Zi'an always raised his head and pretended to be nothing, but he listened very seriously.

Occasionally, their eyes met, but after a split second, they dodged. Everything was like gunsmoke, and the classroom returned to its previous state. Gradually, the classmates seemed to have forgotten the entanglement between Mu Zi'an and Ling Yue, and even they gradually forgot the previous unpleasantness.

Look, the years of youth are such small-bellied chicken intestines, and they are so easy to forget. Only by forgetting can we set sail and go farther away.

The cold wind carried the fallen leaves on the ground, and the days were getting colder, and winter was coming. Lin Yawen is still as usual, listening carefully to classes and doing homework every day. Every once in a while, Ling Yue would lend his math notebook to Lin Yawen, and let Lin Yawen use the evening time to systematically sort out the knowledge points he had learned a while ago. When encountering a topic that she can't know, Lin Yawen will mark it, and the next day, Ling Yue will tell her again.

Soon after, Lin Yawen's math score finally jumped from failing to more than 90 points. Teacher Wang, who has always been serious and unsmiling, also gave Lin Yawen an appreciative smile for the first time.

"I did well in the exam, keep working hard, Lin Yawen!" After talking about the knowledge points of the day, Mr. Wang walked to Lin Yawen's seat and knocked on Lin Yawen's desk with great satisfaction. Lin Yawen nodded happily and slightly shyly, and Teacher Wang paced to the door of the classroom as before, lit a cigarette outside the door, and smoked silently.

The whole class got used to Mr. Wang's habit of a cigarette after class, so the classroom was the same as usual:

Su Xiaoyun was doing the question, whispering to her tablemates, and she didn't know what happy things they were talking about, she giggled with laughter, and her cheeks were flushed. Ling Yue stared at the exercises on the desk with a serious face, squinting thoughtfully, and occasionally taking a pencil to draw dots on the paper. Mu Zi'an lay on the table, knocked the edge of the desk with a ballpoint pen casually, and then sat up with a sudden spirit, and quickly wrote and drew on the homework book.

Lin Yawen scratched his head and made an angle bisector on the triangle, and the idea of that question was instantaneous.

There was a little noise in the classroom, like a calm river flowing through a slightly uneven section. When Mr. Wang heard the noise, he stood at the door of the classroom with a cigarette, coughed lightly, and the noisy lake fell silent, and the students who bit their ears and spoke bowed their heads like frightened birds. Teacher Wang looked at them, raised his thick black eyebrows, and glared at them fiercely.

At the end of class, Lin Yawen chased after Teacher Wang and asked a proof question that she didn't understand very well, and Teacher Wang stood in the corridor at the door of the classroom, and a few words made her chaotic brain suddenly clear. When Lin Yawen turned around and went back to the classroom, he inadvertently saw a male teacher with black-rimmed glasses walking out of the office where the math teacher was.

The male teacher had a small blackboard in his hand with the words "No more soap in the math group" written on it, followed by several large exclamation points. He hung the blackboard on the office door and flashed into the office with a smile.
