Xu Zhaixing closed his eyes hard, looked at his hands in disbelief, and touched his waist.

Next to her, Cheng You was still distressed about the new version of "The Temptation of the Wolf" that she had queued up for several hours to buy. She took out a scented tissue and carefully dried the water stains on the pages of the book, and then looked over it with a look of disgust.

Xu Zhaixing was still covered, with obvious tears in the corners of his eyes.

Cheng You suddenly became happy: "It's not saliva?! Ah, ah, that's great! Oh, no, what's wrong with you, Zhaixing? Why are you crying while sleeping?"

Xu Zhaixing struggled to call out her name: "...Cheng You?"

They lost contact after graduating from high school, and they hadn't called her by this name for many years. She didn't know if she remembered it correctly.

Cheng You came over confused and poked her face: "What's wrong with you? Why are you so stupid?"

The school bell rang in my ears.

Cheng You quickly stuffed the novel into his desk and took out the book he was going to use for this class. Xu Zhaixing saw a few big words on the book: Grade 1 Mathematics.

Freshman year of high school?

Ten years ago?

Is it a dream?

High school mathematics teacher Cao Jumei walked into the classroom with the bell ringing. She still looked like herself, with the popular curly hair, a thin and high-pitched voice, and the rigidity and sternness of a mathematics teacher.

"Sit down! Day after day, my mind is not on study! Liu Qingshan! I am talking about you, and you are still laughing! Take your legs off! What kind of classroom is this? Are you still crossing your legs? Do you want to stop?

Make you a cup of tea?"

The classroom burst into laughter.

Cao Jumei patted the podium heavily with her textbook, stirring up the chalk dust in the air. "Everyone, sit tight! Let's start the lecture. Turn to Chapter 2.2. Today we will learn the logarithmic function."

The sound of turning books was heard all around.

Cheng You flipped through the book and saw that Xu Zhaixing was still stunned. He poked her arm with the tip of his pen and lowered his voice: "Why are you stunned? Do you want to be called on by Teacher Cao?"

Xu Zhaixing finally woke up little by little from his daze.

She opened the book with stiff fingers, staring at the function formulas that she had forgotten for many years, and her heart beat faster.

It's not a dream, it's real.

She went back ten years ago.

My mother is not sick yet, my father is not paralyzed yet, and my family is not bankrupt yet.

Cen Feng...is still alive.

Everyone she loves is still alive.
