"The P that Yan Yun said is the intersection of the quadratic function and the axis of symmetry, which is the vertex of this function. Qi also helped Yan Yun explain.

"Who said it, I'm a heavy taste", Yan Yun picked up the "P" and shook it in front of Shen Xi and Bao Bao before asking, "Do you two eat it?"

Bao Bao and Shen Xi began to feel a little loveless because of their careless friends.

Qi Yi felt that the Yan Yun in front of him was vivid and interesting, obviously it was the Yan Yun he knew, but it didn't seem to be.

In the four years of youth, no matter how big the changes are, they are actually normal.

When I was in high school, I always thought that the college entrance examination was the most important turning point in my life, but in fact, looking back, it was just an exam, even if I had good grades enough to be admitted to Peking University and Tsinghua University, wouldn't someone be dropped out and expelled every year?

The college entrance examination is not as important as imagined.

In the four years of college, Qi Yi and Yan Yun are not only not in the same school, the same city, or even the same country.

What does it mean to miss each other for four years? Qi Yi has not yet found the answer to this question.

At dinner, in addition to occasionally joining the conversation, Qi Yi spent more time thinking about a question about love.

If he still loves Yan Yun, then does Yan Yun still love him?

Compared with high school, do they know more about what love is?

Now that he thinks about it, Qi Yi realized that he and Yan Yun actually didn't even have a formal breakup.

At that time, after Yan Yun said begging Qi Yi to let her go, she never spoke to Qi Yi again.

Qi Yi still can't figure out if he is still in love with Yan Yun, should he continue the unfinished relationship, or do he need to pursue the person he once fell in love again?

Yan Yun's "Epitaph" untied Qi Yi's heart knot.

The past that Qi Yi once refused to remember, now it is pouring like a tide.

In the past few years, Qi Yi has always regarded his relationship with Yan Yun as the biggest failure in high school and the biggest failure in his life before college.

This relationship hurt Qi so much that he didn't even want to have contact with a high school classmate.

Qi Yi didn't know if he couldn't wait to come to Melbourne because of the solution of the misunderstanding, or because of his long-suppressed emotions, which could only be released when he saw Yan Yun.

"Qi Yi, where do you stay at night?" Yan Yun's question interrupted Qi Yi's inner entanglement.

"Staying at the casino. Qi Yi replied.

"It's so close, it's a short walk, so it's no wonder you're visiting Skydeck. Now that it's almost dark, you can go up and have a look. Do you two want to be together?" Yan Yun asked Bao Bao and Shen Xi.

"Don't, every time a family or friend comes to play, I have to accompany him once, Bao Bao and I, at least a dozen times, you two please, come back as late as you want." Shen Xi directly rejected Yan Yun's proposal.

"yes, and even if we were to go up, we wouldn't be with the two of you, and we wouldn't know who was the light bulb for whom. "Bao Bao has always breathed out of the same nostril as Shen Xi.

"It's not been a day or two since I've been a light bulb for the two of you, you continue to be so yin and yang, be careful that I turn up my wattage permanently. Yan Yun's words were full of threats.

Qi Yi didn't want to admit the fact that he had already gone to Skydeck in the morning.

For if he had said so, he could have thought of no better reason why he had appeared at the door of the Eureka-Tower in the evening.

Moreover, as Yan Yun said, the scenery of the observation deck during the day and the observation deck at night is completely different, so why not go again?

If Yan Yun knew that Qi Yi had already gone up, he would definitely not take him up again, because Melbourne's observation deck is not only Skydeck, but also an observation deck called "Oberzevation-Deck".

At night, the Eureka Building, the 88th floor of the Skydeck, exudes a romantic atmosphere, which is completely different from the feeling of the day.

Even the "cliff box" that requires a bit of courage to try during the day does not require so much courage at night due to the change of light. (Note 1)

The Skydeck at night is the same as during the day, and you can see many, many buildings.

But because of the height, it's hard to figure out which specific building is where unless you're particularly familiar with Melbourne.

Except for the huge crown sign neon sign at the Crown Casino in Melbourne.

At this moment, the scenery in front of Qi Yi and the scenery in Yan Yun's photo have been integrated.

If it weren't for that huge neon light, Qi wouldn't have known Yan Yun's approximate location in Melbourne.

This is what it will be, after Qi Yi arrives in Melbourne, he will choose to stay in a casino hotel.

Here is the person he was looking for, and here is the sign that brought him to find someone.

"Do you have any issues to do in Melbourne this time, haven't you been at Stanford?" Yan Yun asked Qi Yi.

"You know I went to the United States?" Qi Yi felt a little strange, "I haven't talked about it with my classmates." ”

"You are not in the rivers and lakes, but the rivers and lakes always have your legends. You went to Stanford in your sophomore year, right?" Yan Yun looked for Qi Yi to confirm.

"Well, who do you listen to. Qi Yi was still curious.

"Didn't Liu Siyan from the second class also go to Peking University? He saw you in the public list of exchange students, and then he told me about my tablemate, Jin Jin, and Jin Jin told me again. Yan Yun briefly summarized his path to get the news.

"Is it okay to go around like this?" Qi Yi has always felt that his relationship with his high school classmates has been completely severed.

I don't know if it's because of the mathematical tradition of Wenzhou Middle School or what, the three people in Yan Yun's class who went to Tsinghua University and Peking University all chose mathematics in unison.

However, two of the three went to Tsinghua University, and only Qi Yi chose Peking University.

If there is no Peking University in your own class, it does not mean that other classes do not have it.

With the popularity of the school grass Qi in Wenzhou Middle School, it is normal for students from other classes to go to Peking University to know that Qi is also in the Department of Mathematics of Peking University.

Note 1:

The cliff box is nearly 300 meters in mid-air, and can be slowly pushed out of the transparent glass room three meters away from the building. The Eureka Skydeck is the world's first and only observation deck with a "cliff box".

Cliff boxes require a separate ticket.

There are many types of Skydeck packages, and those who live in Melbourne who especially like to go to the observation deck can buy an annual pass.

Of course, for tourists, it is enough to buy a "sun, moon and stars" package at most, that is, like Qi Yi, come up once during the day and come up again at night, such a package is cheaper than buying two tickets.
