My winter break homework was exposed, and I, a vocational school student, am now being snapped up by

The school's grove of trees is located on the north side of the playground.

It is located at the northernmost point of the No. 1 Middle School.

A lake lies just across the woods.

Standing in the woods, you can enjoy a view of the lake in the distance.

When Lin Chen walked into the grove, he saw a figure sitting on a bench in the woods.

Upon closer inspection, he found Chen Xiaoxiao, the woman he had arranged to meet.

Chen Xiaoxiao seemed lost in thought, staring blankly at the lake.

Lin Chen didn't know how to start the conversation, so he coughed a few times.

"Cough cough!"

Chen Xiaoxiao looked up when she heard the sound.

Upon seeing that it was Lin Chen, she also showed an uneasy expression.

"You've arrived? Sit...please sit down."

Chen Xiaoxiao sat on one side of the chair, gesturing for Lin Chen to sit down.

Although Chen Xiaoxiao took the initiative to invite her, she didn't say a word afterward.

Lin Chen, with one side of his buttock resting on the chair, was also restless.

I had no choice but to look around and try to distract myself.

At that moment, his gaze suddenly fell on Chen Xiaoxiao's fair neck.

There was a noticeable black mole there.

Lin Chen stared at the black mole, lost in thought for a moment.

Under his burning gaze, Chen Xiaoxiao finally realized what was happening.

"What are you looking at?"

"Your mole? I didn't know it was still there?"

Chen Xiaoxiao was stunned for a moment, then blushed.

She suddenly remembered a conversation they had in junior high school.

Back then, Chen Xiaoxiao and Lin Chen were deskmates.

During one class, she noticed that Lin Chen kept staring at her neck.

"Lin Chen, what are you looking at?"

"Look at your neck, there's a mole there."

What's so interesting about moles?

"I want to remember what it looks like, so that many years later, when you look different, I can still recognize you by this mole!"

……

A blush instantly spread across Chen Xiaoxiao's fair face.

"You really are the Lin Chen I know?"

"Huh? You didn't recognize me after all?"

"Yes. I asked you to come here to confirm whether you are Lin Chen or not."

Lin Chen was stunned. So that's why she contacted him?

He thought...

"Chen Xiaoxiao! Have I changed that much?"

"Does this need confirmation?"

Lin Chen stared wide-eyed.

Even though she recognized Chen Xiaoxiao at a glance, why did she still have to find her separately to confirm her identity?

"Of course? Isn't the Lin Chen I know going to vocational school?"

"Who knew you'd suddenly end up at our No. 1 High School?"

"And what's wrong with your math? You definitely couldn't have solved that problem back then!"

Chen Xiaoxiao said with a self-righteous expression.

"Can't I just suddenly have an epiphany?"

"Let me tell you, I'm really good at math now! Compared to me, your math skills are utterly terrible!"

"Pah! Pah! I think you've gotten thicker-skinned! You never used to brag like that!"

"You don't believe me? Then how do you explain that I'm here at No. 1 High School now? Let me tell you, the reason I came here is because I've already been admitted to a top university, and I'm just here for a few months as a transition."

"Huh? Is the kind of guaranteed admission you're talking about the kind I understand?"

"You do not believe?"

Lin Chen raised an eyebrow and pointed a thumbs-up at himself: "What you're standing in front of you now is a future Tsinghua or Peking University student!"

"puff!"

Chen Xiaoxiao suddenly burst into laughter.

"Hahaha, Lin Chen, you've really changed. Not only are you shameless, but you also love to brag!"

"I really got accepted into Tsinghua and Peking Universities through the guaranteed admission program!"

Lin Chen got angry and raised an eyebrow, saying, "If you don't believe me, then try it. Give me a few math problems and see if I can answer them!"

"you sure?"

Chen Xiaoxiao was also a little curious.

Look at his confident vow.

Could it be that Lin Chen was really recommended for university admission?

Or will they be accepted by Tsinghua or Peking University?

Is that impossible? A vocational school graduate can be recommended for admission to Tsinghua or Peking University?

"Come on, come on!"

Lin Chen patted his chest.

"That……"

Chen Xiaoxiao hesitated for a moment. If she really had to come up with a question, she couldn't think of one right away.

But soon, an idea popped into Chen Xiaoxiao's head.

"For the first question, r=2a*(1+cosθ), draw out this formula for me."

"This question..."

Upon hearing Chen Xiaoxiao's question, Lin Chen immediately had an answer in his mind.

At the same time, memories of the past also appeared before my eyes.

……

That was at my junior high school graduation ceremony.

After everyone took their last graduation photo together...

Chen Xiaoxiao slipped a note into Lin Chen's hand.

"Lin Chen! These are my last words to you! Untie them!"

Watching Chen Xiaoxiao leave after saying just one sentence.

Lin Chen opened the note in his hand.

r=2a*(1+cosθ)……

[（x+52.8）*5-3.9343]/0.5-10X=？

"What? You've already graduated, are you still trying to show off your intelligence in front of me?"

……

Lin Chen still remembers.

At that time.

Lin Chen, a third-year junior high student, casually threw the note away.

He felt as if Chen Xiaoxiao was mocking him by leaving him with two questions at the end.

However, now that things have come to this, Lin Chen understands the true meaning of these two questions.

"What's wrong? A student who was recommended to Tsinghua or Peking University can't even solve such a simple problem?"

“This is the Descartes cardioid,” Lin Chen said casually.

Chen Xiaoxiao stared at Lin Chen with her mouth agape, her face filled with disbelief.

"You...you got it right. Next question is number two!"

“[（x+52.8）*5-3.9343]/0.5-10X等于多少？”

Lin Chen gave his answer without hesitation.

"520.1314."

Upon hearing this answer, Lin Chen couldn't help but shed tears.

It turns out that the note Chen Xiaoxiao gave him back then was actually a confession.

It's laughable that my past self, because of my poor math skills, completely failed to understand what she meant.

When Chen Xiaoxiao saw Lin Chen suddenly cry, she was immediately panicked.

Why are you crying?

"Your answers are all correct! I believe you! Lin Chen, don't cry!"

Suddenly, Chen Xiaoxiao's little hand felt cold.

Lin Chen grabbed both of her hands.

"Xiaoxiao, I was wrong!"

"What...what did you do wrong?"

"I shouldn't have given up on myself and broken up with you back then! This time I won't let go again! No matter where you go from now on, I'll be with you!"

"You, you, you... what nonsense are you talking about?"

Chen Xiaoxiao's face turned as red as a big apple, even her ears turned red.

"You are my carbon tetrachloride!"

"I am sin, you are cos, we don't seek the sum of squares, we only seek the tan!"

"If your heart is the X-axis, then I am a sine function!"

Lin Chen's words might sound like gibberish to others.

But as a top student, Chen Xiaoxiao understood.

The first sentence states that carbon tetrachloride is a chemical substance in which all four hydrogen atoms in its molecule are replaced by chlorine atoms, and therefore cannot be replaced by other atoms, symbolizing its uniqueness and irreplaceability.

The second statement states that the sum of the squares of sin and cos is 1, and sin divided by cos gives tan, which ranges from negative infinity to positive infinity. This implies that the feelings between the two people are like tan, extending infinitely, endlessly, and forever.

The third statement, that the sine function always revolves around the X-axis, is even more straightforward.

So after hearing these words, Chen Xiaoxiao lowered her head.

Tears flowed uncontrollably.
