“Hiss… Don’t move, don’t move.”

“Ouch! That hurts, Bro Lu!!!”

“…”

Lu Yu cradled his arm, sucked in a sharp breath, and shot Ren Jie an exasperated look.

“I’m the one injured. Why are you yelling about the pain?”

“…’Cause it *looks* painful,” Ren Jie mumbled miserably.

Lu Yu rolled his eyes.

They were heading to the infirmary—Lu Yu had scraped a tiny hole on his elbow.

Not big. Barely the size of a pinky nail. Shallow. Just a surface scrape.

Lu Yu thought it was fine, but Ren Jie rambled on about tetanus and worst-case scenarios.

Too lazy to argue, Lu Yu just followed.

The route passed the basketball court beneath Teaching Building One.

No sooner had they stepped out than a figure blocked their path.

Ren Jie recognized that silhouette instantly. He glanced up—and shrank back, unnerved.

Lin Beixing had been glancing toward the court. Hearing Ren Jie’s loud wail, she came to check.

And saw the two boys shoving each other playfully.

Her gaze shifted.

Those usually gentle eyes now held a cold, sharp edge—like a hidden blade.

Ren Jie ducked behind Lu Yu. “Not my fault, sister-in-law!!!”

“Blame those freshman brats in PE! They weren’t watching and bumped into Bro Lu!!!”

“Sis—” The title made Lin Beixing’s pulse skip. She quickly steadied herself, eyes locking onto Lu Yu.

She bit her lower lip.

“Infirmary.”

“We’re already on our way.”

Lin Beixing asked. Lu Yu answered.

Ren Jie suddenly felt like a third wheel and stepped back.

“Uh, Class Rep Lin, why don’t *you* take Bro Lu? I’m PE monitor—I’ve got to gather everyone soon…”

“I’ll handle the excuse with the PE teacher. You two go ahead.”

He shot Lu Yu a meaningful glance.

Lu Yu refused to read it. *Betrayed by my own bro.*

Lin Beixing looked fierce.

Lu Yu almost hesitated to walk with her.

Ren Jie vanished. Lu Yu glanced at his scrape. “Just a scratch. Not serious. Skip it?”

Lin Beixing, unusually firm, grabbed his wrist. “As class rep, I’m responsible. That rusty wire mesh by the court? Who knows what’s on it. Come see the nurse.”

Her tone left no room. Lu Yu trailed lazily behind, gaze drifting to the top of her head.

The bow ribbon matched her black ponytail perfectly, swaying gently against her smooth hair.

*When I was in her body… I never noticed this.*

“…After all, I do have partial rights to your body.”

Lin Beixing didn’t know who she was arguing with.

Her cheeks warmed. Glancing at her own hand clutching his arm, she added hastily—*too* hastily.

Lu Yu’s steps faltered.

“You planning to kill yourself?”

“What?! No! I’m scared of everything—I’d never!”

“And that ‘body swap = your body’s self-protection mechanism’ theory? Still just your guess. Unproven, right?”

Lu Yu fell silent. Lin Beixing looked up.

“No one knows if we’ll swap back tomorrow, today… or the next second. So stay healthy.”

She wrapped concern in duty.

Because beyond duty? She had no other excuse to care *this* much.

Undeniable: Lu Yu was special.

Lin Beixing wasn’t this attentive to every boy. Smiling yes—but distant. She mastered that gentle-yet-untouchable balance.

Beneath the blazing sun, they reached the nurse’s office.

Packed. Summer afternoons meant accidents.

When Lu Yu’s turn came, the nurse glanced at the scrape, tossed him iodine swabs, and moved on.

Lu Yu sank into a corridor chair, swabs in hand.

*Told you it was nothing.* Relief washed over him. *No tetanus shot. Thank goodness.*

Lin Beixing said nothing. Opened the pack. Bent a swab—*click*—it soaked up the solution.

“Hiss—!”

Shallow, but stung. Lu Yu flinched.

“Hurts?” Lin Beixing slowed.

He nodded. “Yeah.”

She frowned, blew softly on his elbow.

Cool air brushed the medicated skin.

“Better now…?” she whispered.

*Blowing on wounds? That’s for toddlers.*

Lu Yu almost smirked—but her earnest face made him… enjoy it.

He shook his head.

“No…” Paused. Nodded. “Still kinda hurts.”

“I’ll blow again.”

Generous. She held his arm, blowing like he was five.

Lu Yu bit back laughter, face scrunched in fake pain.

The dismissal bell rang. Ten minutes till next class.

Lin Beixing glanced up—

Lu Yu’s lips pressed tight, but his mouth twitched upward. *He’s laughing.*

She froze. Gaze darkened.

“Lu Yu.”

“…Hmm?”

She pressed the swab firmly onto the wound.

“…Ow.” *Real* pain this time.

Lin Beixing huffed, yanked him up. “Up. Classroom. *Now.*”
