With unclear thoughts, Ye Yu returned to the classroom, and soon the head teacher came in to preside over the class meeting. After the class meeting ended, Ye Yu stood up and tidied up his clothes, and then walked to the location of the second class of the third year.

When Ye Yu arrived at the door of the second class of the third year, the teacher was already waiting at the door, and hurriedly walked over to say hello.

"Hello, teacher~"

The teacher nodded and smiled: "Come, meet your juniors"

After speaking, the teacher pushed the classroom away and walked in with Ye Yu.

When the two walked into the classroom, the classroom, which was originally a bit noisy, suddenly became quiet.

The teacher walked to the middle of the podium and cleared his throat and said, "Cough~~ Students, I believe everyone has seen Senior Ye Yu just now!" Ye Yu is the most outstanding student the teacher has ever taught, not to mention the grades, the first in the school! And the moral character is even better, you will soon be promoted to the fourth grade, and you will also face the test of taking the university entrance examination! So this time, the teacher specially asked Ye Yu to talk to you about his learning methods, and you all have to listen carefully! ”

"Inside!!" The children echoed in unison.

But it's hard to say how many people really want to hear it, but the crowd has bright and excited eyes, and the owner who shows his eyes is particularly eager to hear it

And Ye Yu, who was standing not far from the teacher, was stunned at the moment, because he saw two unexpected people in the classroom: the busy people of the future girls' generation, Xu Xian and Yun'er!

Especially when he saw Xu Xian looking at him with excitement and adoration, but Yun'er's eyes were a little unkind, he couldn't help frowning. As a former sone, he naturally knew that Yuna and Xu Xian were studying at Dayong High School where he was located, but for so many years, because of his habit of not leaving the classroom, he had never seen these two girls who were one grade lower than him, not to mention that he didn't want to see them.

So gradually, he has forgotten that there are still these two people in Dayong Middle School.

Unexpectedly, today, the teacher came to encourage the younger students, and I unexpectedly saw it.

If he could, Ye Yu would have turned around and left immediately without saying a word, but not now, because he promised the teacher! So when the teacher introduced him, he had no choice but to walk to the podium.

Ye Yu secretly took a deep breath, calmed down his feelings, and then smiled: "Hello everyone, I believe everyone knows me, so I will share my learning experience with you now, I hope it will help you~"

Then Ye Yu began to share his so-called learning experience, saying this, he still has a real learning experience, after all, compared with ****, South Korea's secondary education is too pediatric, in order to get good grades when he was in ****, the learning method he learned during that time was absolutely reliable! In addition, he often tutors his classmates and teaches younger students, which is too simple.

So Ye Yu began to share his experience from various subjects, and Xu Xian and other scholars in the audience began to take notes seriously.

Although Ye Yu was talking about it on the stage, his eyes kept staggering off Xu Xian and Lin Yun'er, and he tried not to look at them.

According to Murphy's Law, the more you don't want things to happen, the more things will always go in the direction you hate the most

Sure enough, when Ye Yu said how to learn mathematics, the problem came.

"Inside~" Xu Xian raised his hand.

The corners of Ye Yu's eyes twitched, and he wanted to pretend that he couldn't see it, but he couldn't imagine that the extremely active teacher took the lead in speaking: "Nei, Xu Zhuxian, do you have any questions?" ”

Xu Xian stood up with his notebook and began to ask seriously: "As Ye Yu's predecessor said just now, we should pay attention to the method of learning mathematics, and we can use the principle of transformation to turn unfamiliar and difficult problems into familiar, easy-to-solve and solved problems, and turn abstract problems into concrete and intuitive problems; Turning the complex into a simple problem; Turning the general into a special problem; Turning practical problems into mathematical problems, etc., makes the problems easy to solve. I didn't understand, I want to ask, what is the specific method."

Ye Yu listened to Xu Xian's serious question, and his eyes eager for knowledge, and suddenly felt powerless.

But under the gesture of the teacher's eyes, Ye Yu had to answer positively.

"That's a good question!" Ye Yu answered casually, and it could be seen that Xu Xian's eyes lit up, and he was a little helpless.

"In fact, there are several common transformation methods, let me start with two relatively simple ones" Ye Yu had no choice but to adjust his mentality and tutor Xu Xian as an ordinary classmate: "First, the direct transformation method: directly transform the original problem into a basic theorem, a basic formula or a basic graph problem. The second type of commutation method: the use of "commutation" to convert the formula into a rational formula or to reduce the idempotency of the whole formula, etc., to transform the more complex functions, equations, and inequality problems into basic problems that are easy to solve. ”

Then Ye Yu turned around and wrote a few questions on the blackboard, and explained them with detailed solution methods, the transformation method and the exchange method just mentioned.

And Xu Xian also listened very carefully, taking notes, and when Ye Yu solved the seemingly very complex math problem in a very simple way, Xu Xian's eyes showed extremely shocked and admiring eyes: It turns out that learning can still be learned like this?

Ye Yu's method opened a wide door for Xu Xian, who had been relying on rote memorization of formulas.

But Yun'er, who saw her best friend's adoring gaze on the side, was not happy, as if her favorite toy had been robbed, she stared at Ye Yu with what she thought was the most ferocious gaze, and kept cursing in her heart: Nerd! It's amazing to read!!

When Ye Yu finished answering, he took the lead in saying without waiting for Xu Xian to ask again: "Because of time, today's sharing is here, I hope you will work hard in the future!" Win glory for the second class of the third year! Thank you~"

After Ye Yu finished speaking, he immediately got off the podium and walked in front of the teacher: "Teacher~ I'll leave the rest to you, I'll go back to class first"

The teacher also felt that it was almost the same, and nodded very satisfied: "Okay~ Go back!" Then he looked at the children: "Everyone don't thank Senior Ye Yu yet!" ”

"Inside~Ye Yu senior, Kansan Amida !!" The classmates immediately stood up and bowed to Ye Yu.

"Hehe~" Ye Yu smiled at them, then bowed slightly to the teacher, and then flashed.

As soon as he walked out of the door, Ye Yu let out a long breath, he was not as relaxed as others imagined just now.

Although he is no longer sone, after all, he has liked girlhood for 7 years, and the name Girls' Generation has accompanied him through 7 years of loneliness, and that kind of feeling is not that it will disappear if it disappears.

The change in girlhood seems to him to be a betrayal of sone, and he can hate anyone, he can hate Taeyeon, hate Jessica, and even hate Yoona, but Seo Hyun is the only one he can't hate.

Ye Yu, who had been silent for a long time, took a deep breath at the door, then shook his head and smiled self-deprecatingly: "Hmph~ It's just a stranger~ Why care"

Ye Yu, who returned to the fourth year class again, took out the Chinese book again and looked seriously, and slowly Xu Xian and Yun'er no longer appeared in his thoughts.

As deep as the love, there is as much resentment as possible.

Since Ye Yu liked girls, he has always believed that the girlhood of 9 people is the real girlhood, and if there is no one, the other 8 people are no longer worthy of the title of girls' generation.

And Girls' Generation has not disappointed him and sone for 7 years, whether it is on the show, in private, they are like sisters, when the fans of other groups are crying because of the infighting between idols, he and sone are smiling and watching the play, because they firmly believe that such a thing will never happen to the Girls' Generation they love.

Trust is the biggest fetters of SONE is Girls' Generation, girls trust that no matter how hard it is, no matter when, SONE will never abandon them, and SONE believes that no matter how many years have passed, girls are the original girlhood, their favorite idols, and the most in line with their expectations.

But when this trust is broken overnight, the disappointment and pain are unimaginable.

Especially Ye Yu, he has lived a deceitful life since he was a child, except for the dean teacher, he doesn't trust anyone, including his partners who grew up with him in the orphanage, not to mention all kinds of hypocrisy and deception after entering the society, which makes Ye Yu feel that his world is full of lies.

When Girls' Generation became a group of 8 people, it also shattered the last expectation in Ye Yu's heart.

When he saw the news, his first reaction was to laugh, smile bitterly, looking at the girls' generation photos in the news, he sneered in his heart: Sure enough, life is like a play, it all depends on acting skills! You guys really put on a good show and deceived fans for 8 years! Is it still exposed in the end?! Amusing! It's ridiculous!

What about the promised ten-year covenant? What about the eternal girlhood? Is that how you made your promises?

This world is really still the supreme interest! Although I don't know how much of the relationship between you is true and how much is false, but in the face of interests, the truth and falsehood seem so powerless, right?
