Lu Yu surely had no interest whatsoever in such childish games.  
He stared at Ren Jie’s phone for a while,  
then pulled his arm back and slumped onto the desk.  

“I’ll leave you to figure it out. I’m sleepy—gonna take a nap.”  

“What? You’re seriously going to sleep this early in the morning?”  
Ren Jie shook his shoulder. “We’re going over last week’s monthly exam papers today! The results will be handed out soon, and I doubt the teacher will let you sleep through class.”  

Truth be told, Lu Yu wasn’t tired at all—he just wanted to avoid answering any more of Ren Jie’s questions.  
He buried his head in his arms, pretending not to hear anything—until someone approached.  

That person walked with a confident stride, carrying a faint, clean fragrance Lu Yu recognized instantly.  
After all, he’d been surrounded by that very scent all day yesterday.  

“Lu Yu.”  
She tapped lightly on his desk and spoke in a calm, measured tone.  
“Your math homework.”  

“Oh.”  
Lu Yu lifted his head and met Lin Beixing’s eyes.  
Under Ren Jie’s utterly stunned gaze, he reached into his bag and pulled out a complete set of math assignments.  

“No way!”  
Ren Jie’s jaw nearly hit the floor as he saw the pages densely filled with detailed solutions.  
“You actually did your homework?!” he exclaimed in disbelief.  

Lu Yu simply nodded, calmly handing the papers to Lin Beixing.  

Lin Beixing clutched his homework, utterly speechless—because this assignment was actually hers.  
She’d stayed up late into the night completing two sets of homework—hers and Lu Yu’s.  
And after switching back to her own body, she discovered that Lu Yu hadn’t practiced piano at all using her body; worse yet, he’d even faked an absurd excuse to skip class.  

Now, not only did she have to fret over the risk of her “period excuse” being exposed,  
but she also had to make up for yesterday’s missed practice—double the usual amount—tonight.  

Beixing was miserable—but she couldn’t say a word.  

She gave Lu Yu a long, meaningful look, then placed a test paper on his desk.  
“Here.”  

While collecting homework, she was also distributing the graded monthly math exam papers.  
Each had a score clearly marked in the top right corner.  

Lin Beixing didn’t look well. Dark circles shadowed her usually clear eyes—evidence of a sleepless night.  
Standing before Lu Yu, she hesitated, watching him carefully.  
After a long pause, she finally asked, voice tinged with uncertainty:  

“Lu Yu… are you… actually good at studying?”  

“…Huh?”  
Lu Yu had just opened his own exam paper.  
Boldly scrawled in the top right corner were the glaring characters: “5 Points!”  

Five points. It meant Lu Yu had gotten only two multiple-choice questions and one fill-in-the-blank correct—pure luck.  

He held up the paper, locking eyes with Lin Beixing.  
The stark “5 Points” on the sheet answered her question more clearly than words ever could.  

“What’s going on? What happened?!”  
Ren Jie, who’d been watching like a curious spectator, leaned in so close his nose nearly touched the paper.  
After flipping through it thoroughly, he confirmed without doubt—this five-point disaster was indeed his buddy Lu Ge’s.  

“What’s wrong, sis—uh, I mean, Class Rep Lin? Did my Lu Ge do something again?”  

“No…” Lin Beixing bit her lip and shook her head.  
“What about your homework, Ren Jie?”  

She shifted her gaze away from Lu Yu’s impassive face to his seatmate.  

“Heh…” Ren Jie scratched his head sheepishly.  
“I didn’t finish… Can I just hand in what I’ve got for now? If the teacher calls me out, I’ll take full responsibility—okay, Class Rep?”  

Lin Beixing’s mind was elsewhere. She vaguely heard him ask “okay?” and gave a distracted nod.  
“Fine.”  

“Sweet! Thanks, Class Rep!”  
Ren Jie breathed a sigh of relief, narrowly escaping trouble.  

“Here’s your exam paper. Keep it.”  
Lin Beixing placed his test on the desk, glanced once more at Lu Yu, and walked off with the stack of homework.  

Ren Jie picked up his own paper, saw the identical score, and let out a yelp. He turned to Lu Yu.  
“Dude! I got the exact same score as you!”  

Lu Yu had already buried his head back on the desk. He gave a half-hearted “Oh.”  
His eyes, hidden beneath the desk, fixated on the glaring red “5.” His dark pupils were lost in thought, unreadable.  

“Five points, bro! I actually did worse—I had thirty last time! Ugh, gotta blame the lack of multiple-choice questions…  
Mr. Zhang’s getting stingier. He made the test himself and probably swapped out the multiple-choice to stop us from guessing…”  

Ren Jie grumbled with resignation, but as he kept talking, Lu Yu fell completely silent.  

“Hey… you’re actually asleep?”  
Ren Jie shook his head at his dozing friend.  

He was considerate, though. Whenever Lu Yu slept, Ren Jie—ever the loyal roommate and desk-mate—would keep watch for the homeroom teacher or the discipline officer. At the first sign of trouble, he’d wake Lu Yu immediately.  

But this was senior year. Unlike in grades ten and eleven, teachers weren’t as strict anymore.  
Students who’d given up on themselves were simply… left behind. No one bothered dragging them out of the mud anymore.  

A hot breeze blew through the classroom. Someone had turned off the ceiling fan.  
Lu Yu, irritated, crumpled his test paper and shoved it into his desk drawer.  

Up front, the math teacher energetically began reviewing the exam.  
Lu Yu propped his head on a stack of textbooks, pulled out his phone, and played a few rounds of games.  
Even after pulling off a solo chicken dinner or a pentakill, he felt no joy.  

He switched off his phone and lay quietly in the crook of his arm, bored out of his mind.  

Footsteps approached.  
Then came the familiar sound of knuckles tapping on his desk.  
Annoyed, Lu Yu lifted his head—  

But this time, it wasn’t the sweet-smelling girl.  
It was an elderly woman wearing glasses.  

“Lu Yu,” said Ms. Zhang, her voice neither gentle nor harsh, but firm and unquestionable.  
“If you’re sleepy, go stand at the back. Standing will keep you awake.”  

Lu Yu, though the class slacker, wasn’t a troublemaker. He usually just sat quietly.  
When reprimanded, he never argued—just obeyed without a word.  

“Okay.”  
He pushed himself up lazily from his seat.  

After two steps, the teacher called him back.  
“Bring your test paper.”  

He turned, retrieved his “5 Points” sheet, and walked to the back.  

The whole class watched in silence—it was, after all, class time.  
Only Lin Beixing kept her head down, staring at her own high-scoring paper, fingers clenched lightly into fists.
