“This question—well, we should first think about its root cause. It’s math, after all; the most important thing is the approach. So, you see, this is essentially that, and that is essentially this. In other words, they’re pretty much the same thing.”

“What’s written on the PPT differs from what’s in our textbooks, which just shows—well, actually proves nothing else—so we really ought to focus more on reading our books carefully, right?”

“Alright, class, please look at me. Pay attention to the equation I’ve just written on the blackboard… This equation, you see…”

Mr. Wang continued lecturing enthusiastically, clearly lost in his own world.

Xia Yan diligently took notes, his handwriting neat and elegant—possessing a delicate grace more often seen in girls’ handwriting.

Meanwhile, slumped on the desk, hood up and mask on, Hua Xin lay utterly motionless…

🥺🥱💤😇

Already fast asleep, lulled by what must be the world’s most effective lullaby.

(She’d stayed up late last night and had to wake up early today.)

Beneath the mask was an exceptionally cute, angelic face—looking even more peaceful in sleep than she did at home.

Her sleeve was already damp with drool 😤, as if she were dreaming something delightfully happy.

“Kukuku… chichi…”

“?”

Xia Yan paused his note-taking and turned toward the sound, puzzled.

He saw Mu Feng staring curiously—not at him, but at Hua Xin beside him.

Xia Yan glanced ahead at Mr. Wang, still rambling away, then reluctantly picked up his phone.

He knew it wasn’t just Mu Feng—others in class had also grown curious about Hua Xin.

After all, attending class only twice a week seemed like a rare privilege—and, to many, unfair.

If Hua Xin could skip most classes, why couldn’t others?

Because the class advisor, wanting to protect Hua Xin from discrimination, hadn’t publicly explained the situation.

So, to prevent any future trouble or gossip, Xia Yan had long prepared a plan 😉.

Three days earlier, right after class, he’d addressed the whole class: “Special family circumstances,” he’d said gently, offering a vague but sufficient explanation.

Thanks to his strong interpersonal connections, none of the thirty-some classmates raised objections.

Most college students, after all, are genuinely kind-hearted.

(Though a few still blast loud music or videos at night, scream during online games, have loud video calls with their partners while others sleep, or—like human wrecking balls—leap thunderously from their top bunks. 🤢🤮)

WeChat Group: “Peaky Blinders Helping Marie Curie Find Radium”

Xia Yan: “Hua’s a really nice person—just super shy. I’ll introduce you guys sometime.”  
Mu Feng: “OK, Big Bro Yan.”  
Xiang Guan: “Don’t let Mu the Dog meet her—he’ll just drag her into playing ○○.”  
Mu Feng: “c.nQun柒洱鏾龄⒋⑼齐散 飼.m.”  
Xiang Guan: “Why you yelling at noon, dummy?”  

Xia Yan chuckled, put his phone back down, and returned to his notes.

Suddenly, Mr. Wang’s chalk screeched across the blackboard with a piercing sound.

Hua Xin: “😨😱😭”

Jolted awake from a dreamy harem fantasy with her 2D waifus, Hua Xin lifted her head in confusion, her whole body trembling as if covered in ants 🐜.

Startled and disoriented, the girl instinctively shook her legs 😋.

(What just happened?)  
(What heavenly sound was that? 😇)  
(I really—seriously—want to punch him right now! 👊🏻😡)

But in reality, she just silently turned toward the wall, lifted her mask slightly, and wiped away the drool.

Too scared to speak. Too furious to act. 😤

Feeling the numbness in her arms and legs, she slumped back against the wall.

So… numb… numb… numb… numb…

She tried moving her leg.

Eeek! 😨 So… tingly… amazing… tingly… amazing…

She froze again—afraid that if she moved more, she might accidentally moan aloud.

And she absolutely hadn’t forgotten that Xia Yan was sitting right next to her.

Besides…

She lifted her eyes slightly.

People everywhere.

Men 👨🏻.  
Women 👩🏻.  
Elders 👴🏻.

Thankfully, they were all in front of her… or she’d already be hyperventilating from panic 🥺.

And then—

She turned her head slightly.

Xia Yan was propping his cheek, still watching her with that gentle, ever-present smile.

His profile was strikingly handsome—his teasing eyes easily capable of stealing any girl’s heart.

But Hua Xin whipped her head away and squeezed her eyes shut—not charmed, but consumed by jealousy.

(And there’s also that unfairly hot, sunshiney guy over there… 😭)  
(Why does his smile hurt my eyes so much? 🥺)  
(Does he smile like that at everyone?)  
(Ugh… classic emotional air conditioner. 🖕🏻)

Hua Xin had zero tolerance for cheerful, popular “normies”—especially ones this disgustingly handsome and radiant.

She just knew he’d already broken countless girls’ hearts and tried every position under the sun. 😭😭

Damn it… why don’t shut-ins like her ever get love? 😡  
Why are we doomed to rot in sewers while others party in hotels and bars? 😭

Wait…

Love? 🤔

She suddenly remembered her “water husband.”

Uh… 😰

Quietly grabbing her phone from the desk, she opened her chat with him—turning slightly toward the wall.

The shameless conversation history lay there, untouched.

Past Midnight:  
Invincible Cat Punch: “Carry me to Master. I need to hit Grandmaster.”  
#1 Online Good Son: “Call me hubby 😘.”  
Invincible Cat Punch: “? Call your ass.”  
#1 Online Good Son: “C’mon, c’mon~ Wifey wifey wifey 🥰.”  
“Send me pics of your feet… or your legs… anything 🥵 Muah muah, wifey.”  
Invincible Cat Punch: “…”  
#1 Online Good Son: “Nothing? Then refund me. We’re done.”  
“I knew it—you never loved me. You were just using my skill like a moth drawn to flame, you bad woman.”

Reading this, Hua Xin couldn’t hold back a snort—and sat up abruptly.

But her legs were still numb, so she immediately collapsed back down.

(What happened next? Let’s just say the poor girl had to “sell her soul” and send a leg pic to get free boosting from her “water husband.”)

Later that night:  
#1 Online Good Son: “I love you, wifey 🥰 Kisses everywhere—this weekend I’ll get you to Grandmaster, don’t worry, meow~”

Yes. He even added a “meow.”

Mr. Wang’s lecture droned on, but for Hua Xin, it was just background noise.

Suppressing the urge to reach through the screen (he’s RIGHT BESIDE YOU, silly girl) and strangle him, she typed a message:

Invincible Cat Punch: “What’re you doing, son?”

Vvvv.

Xia Yan, still focused on his notes, noticed the phone beside him suddenly light up—silent, no sound.

Is it Director Li?  
But class isn’t over yet…

He put down his pen, picked up his phone—and saw not a message from the director, but a “Wife”-tagged, specially highlighted notification from his QQ contact.

Reading her message, a faint smile flickered in his eyes.

He rarely admitted it, but Xia Yan was absolutely a foot, leg, face, hand, arm, and… other kind of connoisseur 😋.

Hua Xin’s legs—and those “feet”—had genuinely captivated his high standards.

Otherwise, with all the girls constantly throwing themselves at him, he’d have dated plenty by now… instead of still holding onto his “virgin” status.

But he believed relationships required fate, mutual understanding, aligned values, and genuine affection.

Yet… ever since seeing Hua Xin’s photos…

Facing the wall, Hua Xin read his reply and couldn’t help but twitch her lips in exasperation.

#1 Online Good Son: “In my thoughts, wondering when you’ll step on me, wifey 🥵”
