Jian Zhizhen was confused: "When did you confess?"

Qin Yubai: "Not long after your parents went to the moon, I sent you a math equation for you to solve, and after you solve it, it's what I want to say."

"......" Jian Zhizhen looked at him silently for a while, and her eyes were redder than just now.

She was really wronged and cried this time, and her eyes were full of tears.

Qin Yubai's heart also hung up, and he hurriedly held her face and asked, "What's wrong? Why are you crying?"

Is it because I know his intentions now, so I was moved to cry?

Who knew that Jian Zhizhen slapped his hand away, glared at him and cried and scolded: "You are not human! I just graduated from junior high school, and you asked me to solve such a complex two-dimensional function, how can I solve it? I...... I'm still looking for a teacher, my junior high school teacher can't do it, Qin Yubai, you are really not human!"

Qin Yubai looked at her with a surprised expression.

After Jian Zhizhen lost his temper, he asked slowly, "So you don't know?"

"......" Jian Zhizhen's cry instantly stopped.

Qin Yubai said seriously: "I have thought about all the possibilities, but I never thought that you would not be able to do that question."

Jian Zhizhen was even more angry, and raised his leg and kicked him: "I didn't touch that field at the beginning, I couldn't solve it, and you still asked me about the results every day at the beginning...... Do you know how much damage you've done to my pride!"

"I'm sorry." Qin Yubai pulled her into his arms again and gently patted her back to comfort her.

The original version of the problem came from the mathematician Descartes.

Before he died, he wrote a letter to his lover to Princess Christine, on which there was only one functional formula: r=(1-snθ).

When the princess saw it, she solved the graph of this function and found that it was a ❤ shape.

Qin Yubai was deeply moved by this love story when he was a child, and thought that he must invent a more complex two-dimensional function than this one to confess to his lover.

He then complicates the equation and rewrites the formula, which is ❤z.

At the beginning, he was full of joy waiting for his early love with Jian Zhizhen, but he didn't expect that since then, Jian Zhizhen has slowly distanced himself from him.

He thought about a lot of possibilities:

Could it be that Zhen Zhen just treats him as an older brother?

Could it be that Zhenzhen already has someone he likes?

Don't you know how to change this relationship from childhood to adulthood?

Unexpectedly, she just didn't know how to do it.

He was helpless and relieved, hugging Jian Zhizhen and apologizing: "I'm sorry, I'm sorry, it's all my fault."

For a long time, Jian Zhizhen sniffed and slowly stopped crying.

She now has a sense of helplessness that she can't cry or laugh.

The root cause of their missed puppy love turned out to be these two trivial things that are not worth mentioning!

Sure enough, the confession still has to play a straight ball.

And you have to have a clear result!

Now that the misunderstanding has been explained, it is time to make the other things clear.

Jian Zhizhen raised his head, his reddened eyes looked at Qin Yubai without blinking, and took the initiative to ask him, "Then do you have anything to say to me?"

"Yes." Qin Yubai's expression was very serious.

Jian Zhizhen sat up slightly straighter, his heartbeat involuntarily accelerated, just waiting for his belated confession.

Unexpectedly, Qin Yubai grabbed her hand and wanted to take her to the desk next to her.

"I'll show you how to solve that problem."

Jane: "......" That's what he wants to say to her?

[Qin Wang: I've been moved to cry after listening to it for a long time, I thought you should really have a belated confession next, right? As a result, you are now teaching girls to do problems? I'm so angry, why did I follow such a master, please quickly start my self-destruct program, I want to kill myself! 】

Qin Yubai turned off Qin Wang's vitality mode.

Now I have to concentrate on coaxing Jian Zhizhen, and I don't have time to listen to the misanthropic online suicide.

However, Qin Wang's opinion still has an effect.

Qin Yubai really realized that he shouldn't have taken Jian Zhizhen to do the question when she cried miserably.

He should confess first, and then do the question later.

He opened his mouth and was about to speak, when he suddenly felt that the world was spinning, and he was pressed to the bed by Jian Zhizhen.

Then, I took a set of combination punches from her on the spot, the kind that didn't use force.

This beating didn't hurt, but it was itchy and swishing, and Qin Yubai was not comfortable, so he reached out and pulled Jian Zhizhen into his arms. new

Jian Zhizhen bumped into his chest, and the next second she pushed him hard: "You let go of me and do your questions!"

Qin Yubai hugged her and didn't let go: "Let's do it together."

Jian Zhizhen was still angry: "I don't do it!"

"How can you progress if you don't do it?" Although Qin Yubai didn't have a stern tone when he said this, he really owed a serious look, like a teaching director.

Jian Zhizhen was about to scold again, but Qin Yubai held her waist and hugged her up, so that he could look at her eyes.

His eyes were hot, and his tone was as gentle as ever: "Let's do problems and research together, and we will be together for the rest of our lives, just like your parents, okay?"

Jian Zhizhen looked at him quietly, but he couldn't quite understand, is this a confession?

How can anyone confess like this?

I don't say a word of like, and I don't say anything like "is it good to be my girlfriend".

But she's still so happy.

She thought of when her parents took her to Yan Village after her brother disappeared.

She was very reluctant to part with Qin Yubai, and she cried for a long time.

At that time, her elementary school classmate said, "When Qin Yubai has a girlfriend in the future, you still have to break off your relationship, otherwise you will have to break off your relationship."

This sentence has also become her psychological shadow, and it is also the reason why she has not dared to take too much initiative in the past few years.

But now, no.

Because the people she has always liked since she was a child also like her.

Qin Yubai caressed her face with one hand, and her black and white eyes were all her.

"You haven't answered me yet." He chased for answers.

Jian Zhizhen looked at him silently for a while, but still didn't speak.

She buried her face in his heart, and the whole person lay on top of him.

Qin Yubai hesitated for a while, then stretched out his hand to circle her, tightly.

It would be nice if I could hold her like this all night.

It would be even better if we could do this in the future.

But this warm time did not last long, and suddenly there was a sharp knock on the door outside.

"Did you two sleep?" Lin Yi's voice.

Jian Zhizhen got up from Qin Yubai's body with a brush, glanced back at the door, and then looked at Qin Yubai with a complicated gaze.

"......" Qin Yubai understood.

It was past eleven o'clock in the evening.

If someone else came to them at this time, they would definitely ignore it.

But the person who came was Lin Yi, so it was impossible for Jian Zhizhen to ignore him.

Qin Yubai sighed quietly, so he had to get off the bed and take the initiative to open the door for Jian Zhizhen's brother.

"Something is wrong! I'll have to discuss it with you......" Lin Yi said as he walked inside.
