Second Sister, You're So Dirty

[Ding~ Negative emotions 10002]

As soon as she got home, Second Sister erupted with a wave of negative emotions.

The moment she stepped inside, Second Sister Ren Fanxing saw Cao Cheng lounging on the sofa, watching a military drama—the recently popular Soldiers Sortie, which was being rerun on every TV channel.

But that wasn’t the issue.

Nor was it because Young Master Cao was lazing around watching TV all day.

The real problem was…

The Fourth was sitting beside him like a little maid, massaging his legs and even feeding him fruit.

For some reason, Second Sister’s negative emotions suddenly triggered a critical hit.

Huh?

Cao Cheng jolted in surprise.

The divine treasure chest was complete.

So, Second Sister was back?

The only one who could deliver such an inexplicable critical hit was her.

Eldest Sister might do it too, but only when money was involved.

Without even turning around, Cao Cheng knew exactly who had arrived.

Pretending not to notice, he kept watching TV.

The Fourth hadn’t noticed Second Sister behind her either.

Still obediently pouting, she continued massaging Cao Cheng’s legs—after all, she’d lost the bet.

Plus, she needed something from him. She wanted that Annoying Little Brother to teach her piano. Say what you will about him, but his piano-teaching skills were genuinely impressive.

Besides, this wasn’t the first time they’d been like this. No big deal.

Ahem—

Second Sister cleared her throat pointedly.

Gasp!

The Fourth yanked her hands back and spun around.

“S-S-Second Sister, you’re back.” The Fourth instantly put on an ingratiating smile, her expression dripping with flattery.

“What are you two doing?” Second Sister’s voice was icy.

“Uh, well… Annoying Little Brother—er, his legs were sore, so I was helping him massage them,” The Fourth replied awkwardly.

Cao Cheng turned his head and nodded. “Yeah, my legs went numb from sitting too long. Probably poor circulation leading to venous stasis. Massaging helps stimulate blood flow.”

“You must’ve misunderstood, thinking we were up to something inappropriate, right?”

“But that’s not the case at all.”

“In traditional Chinese medicine, massage is documented in the Yellow Emperor’s Inner Canon. The Plain Questions chapter states: ‘When meridians are blocked, illness arises from numbness, and treatment lies in massage!’”

“This is a time-honored practice, Second Sister. You’re the one with a dirty mind!”

“……”

“……”

The Fourth felt enlightened.

She didn’t understand the Plain Questions, but she’d heard of the Yellow Emperor’s Inner Canon—sounded like a big deal.

And turning the tables like that? Smooth move, Annoying Little Brother.

Second Sister was stunned.

She had no rebuttal.

After a long pause, Second Sister jerked her head toward the door. The Fourth instantly got the hint and scurried away, making a swift exit.

Now, only the two of them remained in the living room.

Even the maids in the kitchen had discreetly vanished.

Second Sister narrowed her beautiful eyes. “Legs uncomfortable? Let me massage them for you. I don’t know traditional medicine, but I’ve studied trauma therapy—back when I practiced martial arts and kept getting injured.”

Her tone and gaze were anything but friendly.

But our Young Master Cao wasn’t scared.

He wasn’t afraid of her making it hurt—he was afraid she wouldn’t massage him at all.

First time’s the hardest. Once she started, there’d be a second, a third…

Eventually, he’d turn this aloof husky of a sister into an aloof little cat.

Both were cold, but the results were different.

Behind a husky’s aloofness was sheer chaos.

But an aloof little cat? That one would knead you with its paws.

……

“Aah—!”

Cao Cheng let out a dramatic cry.

Second Sister’s face darkened. Her outstretched hand froze mid-air as she gritted her teeth. “I haven’t even touched you yet!”

That shout was loud enough for the whole house to hear. Now everyone would think she’d done something to him!

This jerk.

“Huh? Oh, you haven’t? My bad, jumped the gun.” Cao Cheng chuckled sheepishly, straightening up. “Alright, go ahead. Show me what you’ve got.”

Hiss—

The moment her professional hands got to work, he knew just how ruthless she could be.

She really did know trauma therapy.

She might not understand traditional medicine or diagnosing illnesses, but she definitely knew the basics of tendons and pressure points. At the very least, she wasn’t pressing randomly.

This wasn’t just a muscle relaxant—it was proper trauma therapy.

Now that’s what you call skill!

Compared to her, The Fourth was amateur hour.

It hurt, sure, but it was infinitely better than he’d expected.

Second Sister was clearly out for blood, pressing down with brutal precision on every tendon.

If this were some average IT worker—balding, hunched over a desk all day—one squeeze would probably leave their legs numb and screaming in agony.

Her cruelty was downright terrifying.

Good thing she’d met Young Master Cao.

He wasn’t some overworked office drone.

And his body was in peak condition.

So unless she was outright torturing him, the pain was manageable—even borderline pleasant.

But…

Cao Cheng hammed it up, whining, “E-e-easy! Easy there…!”

The more he protested, the more Second Sister enjoyed it.

Her usually cold face cracked into a rare smile—albeit a sadistic one.

Sweat beaded on his forehead.

Cao Cheng deliberately tensed up to work up a sweat. Wouldn’t want to disrespect her efforts, after all.

Suddenly, Second Sister spoke. “Admit you’re wrong.”

“Wrong about what?” Cao Cheng blinked. Wait, was this an interrogation now?

“Just answer. Admit you’re wrong.”

“What did I even do? Ow—!”

“Heh. Admit it.”

“At least tell me what I did wrong!”

Second Sister demanded, “Disrespecting me. Admit it.”

“When did I disrespect you?” Cao Cheng played dumb, keeping up the pained act. No way he’d confess.

A true comrade never caves under pressure!

……

Neither of them noticed.

Ren's Mother had returned.

Old Cao was right behind her.

The moment they stepped in, they saw the two of them like this.

Getting along?

Ren's Mother was touched.

Old Cao was proud.

That’s my boy. Takes after me!

No—surpasses me.

For over half a year, Second Sister had barely acknowledged Old Cao, calling him “Uncle Cao” at most—and even then, fewer than ten times total. Barely spoke to him.

But look at Little Cao now.

Well, well.

Would you believe it?

They’re practically glued together.

Burp—

Old Cao let out an abrupt belch.

Second Sister’s frosty expression—twisted into a sinister grin—suddenly stiffened.

She turned her head and instantly wanted to die of embarrassment.

Tears welling up, Cao Cheng lunged toward Ren's Mother. “Mom, she bullied me! Waaah—I can’t take it anymore!”

Before he could reach her, Old Cao blocked him.

Cao Cheng’s face darkened. Seriously, Old Cao?

You’re guarding against your own son?

……

Ren's Mother swatted Old Cao aside and gently ruffled Cao Cheng’s sweat-dampened hair. “Your Second Sister was just playing with you. She’s not usually like this—it means she likes you.”

“I’m going upstairs.” Second Sister tossed out the words and bolted, her retreat almost frantic.

Ren's Mother smiled softly. “I’ll make you braised pork belly tonight. Sound good?”

“Mhm. I’ll help you prep.”

“As if I’d let you. I’ll help,” Old Cao cut in.

Ren's Mother shot him a look. “My son’s helping. You stay out of it.”

“……”
