Why do you look like a little wife all the time these days? Where did my handsome, dashing, and debonair school hunk boyfriend go?

Are you not going to give me back my Qi Yi quickly?

Speaking of which, you resort to reverse psychology and beating around the bush, but is it really fun to force someone to say those few words?

Since you only say "like" and not "love," why did you give me a love equation when you left?

17·x^2-16|x|y+17y^2=225, I’ve solved it already.

This heart you gave me looks nothing like Descartes’s butt-shaped heart; it’s a very standard heart shape. (note 1)

When I first started solving the equation, I used a blue ink pen to draw it on the coordinate axis.

After solving it, I took a new sheet of paper and drew it with a red pen, filling in the middle of the curve with red paint.

I took a photo, a "bright red heart" full of positive energy is waiting for you in the attachment.

The equation represents your heart, the attachment represents my heart.

Question=>

Today is New Year’s Eve, how is your New Year in Wenzhou?

....................

During the New Year, with the winter in the northern hemisphere and daylight saving time in effect in Melbourne, there’s a three-hour time difference from back home.

By the time it’s past midnight on the first day of the New Year in Melbourne, it’s still only nine o’clock on New Year’s Eve back home.

Yan Yan had just finished drawing the "bright red heart" for Qi Yi in her own sketchbook.

Sketching is the basic skill of all design, and without a solid foundation in sketching, Yan Yan couldn’t have received immediate recognition and started her sophomore year at the University of Melbourne’s School of Architecture and Design.

Yan Dabang liked technology and, during the era when he started his business, there weren’t any computers available for drafting, so he often hand-drew many parts and machinery blueprints.

Yan Yan learned by his example and enjoyed doodling on paper since she was young.

Yan Yan began to teach herself sketching at a very young age.

If it were not for drawing which kept her company from primary school, when she had few friends and was targeted by classmates, those days would have been much more difficult for her.

After sketching for over a decade, Yan Yan now rarely uses sketch pencils and prefers to draw with a pen. To be more professional, she likes to use a technical pen for her pen sketches.

The downside of pen sketching is that you cannot repeatedly modify unsatisfactory areas as you could with pencils or charcoal.

The advantage of pen sketching is that the strokes are more decisive and the works are easier to preserve.

Yan Yan’s architectural pen drawings were praised by many professors during her time at Monash University.

Other students usually used A4-sized paper for their architectural pen drawings, but Yan Yan particularly liked using A3.

In addition to her solid basic skills, Yan Yan’s speed in pen sketching was also quite outstanding.

The paper Yan Yan had just used to solve the equation given to her by Qi Yi was also A3-sized sketch paper.

A tiny red heart in the coordinate system of analytic geometry, situated in the center of a large sketch paper, seemed small and alone.

On New Year’s Eve, one must have something special to show.

Yan Yan thought about it and then drew a wide-eyed, cute short-legged tiger in the upper left corner of the sketch paper.

After she finished, she drew a lifelike squid in the bottom right corner of the sketch paper.

With Qi Yi’s high IQ, he would surely understand what the short-legged tiger and squid symbolized.

Yan Yan was quite satisfied with her "work" and scanned it, attached the file, and sent it along with the email she had already written to Qi Yi.

After sending the email, Yan Yan checked the time, and it was just nine o’clock in the evening in Melbourne.

At night, six o’clock in China, Qi Yi’s family dinner for the Lunar New Year’s Eve certainly hadn’t finished yet, and Yan Yan thought it was highly unlikely that Qi Yi would reply to her email quickly.

Yan Yan turned to a new page in her sketchbook and continued with her favorite architectural pen drawings.

Suddenly, she felt a strong urge to draw the high school campus from her memory.

Every blade of grass and every tree in the campus was etched in Yan Yan’s memory.

Yan Yan remembered every building in the school and the school motto written by Mr. Zhu Ziqing when he taught there in 1923, "Nurture the extraordinary and enlighten the wise to serve the nation," which she thought was odd when she first started school.

However, before reuniting with Qi Yi this time, Yan Yan had long refused to let herself recall that place where she had met Qi Yi.

If one does not graduate, they wouldn’t know what ’alma mater’ truly means.

A person’s affection for their school is mostly unrelated to academics.

It’s mostly about the people at the school and the things that happened there.

A school that holds only memories of study is unlikely to evoke much nostalgia.

Initially, Yan Yan was drawing the architectural structures of her high school campus, but as she drew, she added two people walking shoulder to shoulder across the school field.

Then she added another two people chatting, leaning against the railing outside a classroom.

After that came the striking figure of the flag-raiser at the base of the flagpole and the color guard who looked at the flag-raiser with such intensity that she forgot where the flag was.

Yan Yan had never drawn such a casual and lighthearted architectural pen drawing before.

Yan Yan had been drawing for over two hours, yet her computer had not made any sound indicating she received an email.

These past few days, Qi Yi had been quick to reply as soon as he received an email.

Perhaps today he was busy with the New Year’s celebrations and hadn’t had a chance to sit down in front of his computer.

Even after midnight had passed in Melbourne, when Yan Yan was ready to go to bed, she still hadn’t received a reply from Qi Yi.

Yan Yan decided not to wait any longer. On New Year’s Eve, it was quite normal not to have free time early on.

If she continued to wait, she wouldn’t know how much longer it might be. Anyway, when she woke up the next day, Qi Yi would surely have replied to her.

On the first day of the Year of the Rabbit, Yan Yan wondered what Qi Yi would mention in his email.

He would probably bring up their "great feat" from their second year in high school when they stayed in the library until it closed on New Year’s Eve before being willing to go home.

Yan Yan shook her head; back then, she and Qi Yi truly had a "profound love" for the library.

Note 1:

The symbol ^ here is meant to denote exponentiation.

Actually, Qi Yi could have sent Yan Yan a more advanced three-dimensional "heart."

But firstly, Yan Yan, not being a mathematics major, might not have been able to solve such a complex equation.

Secondly, although current reading apps can display spaces between English words, they still cannot display mathematical formulas.

Not even an X squared can be typed out, so x^2 is used as a substitute.

Don’t even think about those equations with square roots or higher-order terms.

Do we have any Mathematics majors reading this?

Would anyone like to try solving the relatively simple yet very elegant equation for a three-dimensional heart shape?

(x^2 +(9/4)y^2 + z^2 – 1)^3 – x^2z^3 –(9/80)y^2z^3 = 0

If you’re not a math major, just ignore Xiao Mo’s blabbering. After all, it’s already quite a challenging task to clearly represent the original form that this equation should have.

Moreover, you’d have to apply Euler’s Transformation to establish a Cartesian coordinate system in space.

When dating an ordinary person, it’s best not to bring up such equations to avoid being dumped.
