Su Su lay sprawled on Bai Su’s bed like a salted fish that had lost all its dreams, with no desire to bounce anymore.

She felt the fiery sting on her butt, biting her lip as she buried her face in the soft pillow.

Damn, it hurt so much.

That was her only thought.

She never expected Bai Su, that little brat, to show any tenderness—he’d actually spanked his own sister hard, not holding back at all.

Couldn’t he have just gone through the motions? Did he think she had no dignity?!

But if that idiot Bai Su knew, he’d probably snap back, “What dignity does a kid need?”

Thinking this, the fifteen-year-old girl inside Su Su felt deeply wronged.

Her big eyes slowly misted over as she bit her lip, watching Bai Su stand awkwardly beside her, thinking:

“Pervert. Bad brother.”

Yet the old man’s soul still slightly dominant within her refused to lose face in front of this little kid. She fought back tears, huffed, and turned her head away, hiding her vulnerable state from Bai Su.

But Bai Su had already seen it.

He froze, awkwardness flooding him.

What now? His sister clearly hated him as a pervert.

He realized Su Su wasn’t that snotty kid anymore—the one who used to trail behind him, sweetly chirping “Brother, brother.” She’d grown into a nearly adult girl with her own thoughts and personality.

Bai Su unconsciously took in her appearance.

Su Su lay facedown on the bed, turned away in anger, hiding her delicate face. But her profile was clear: petite ears, a soft strand of hair by her earlobe swaying like a willow branch in spring breeze.

Bai Su’s heart suddenly raced.

His gaze drifted to her slender figure, the smooth, slightly plump lines of her back hidden under an oversized nightgown.

Her nape looked smooth and tender; the loose neckline revealed a patch of fair skin that made his breath hitch.

Below the hem, her slender calves peeked out.

She wore cute bubble socks—layers of soft cotton piled on her tiny feet, adorably heart-fluttering.

Bai Su swallowed hard, his hand twitching as he recalled the incredibly soft, bouncy feel from spanking her just moments ago.

For no reason, he felt an urge not to wash his hands today.

Then the little angel of reason whacked his head with a magic wand: “Bai Su, you pervert! She’s your sister!”

He shuddered, snapping back to his senses.

Right! No matter how cute or beautiful Su Su became, she was still his sister.

The chasm of law and ethics stood between them, with public opinion looming heavier overhead.

Even if he confessed his feelings, how would she see him?

A pervert lusting after his sister? A disgusting scumbag? A villain breaking taboos?

Bai Su smiled bitterly, finally calm.

He couldn’t face public ridicule or Su Su’s disgust. He might ignore the first, but the second—he’d never survive it.

A sister was a sister. No matter how angelic she seemed, she’d marry someone else someday.

As the one who’d cared for her longest, understood her best, and loved her most, he’d have to watch her walk down the aisle, radiant in white, throwing herself into another man’s arms. Then he’d shrink into a corner, silently blessing her—that was every brother’s fate.

Such a tragic, heartbreaking fate.

Like a fresh cabbage he’d nurtured being devoured overnight by the neighbor’s pig.

Only brothers knew that despair.

Not every brother was a full-blown sister-con, but their hearts ached the same.

Bai Su’s gaze sharpened.

…If any blind pig eyed his unripe little cabbage, they’d regret it.

He looked down at his “tantrum-throwing” sister and felt sudden peace.

Liking her was wrong. Su Su would find her own happiness, and he had no right to stop it. Even if she brought home some stranger, blushing as she said, “Brother, this is my boyfriend XXX. Isn’t he handsome?”

He’d force a smile: “Of course, Su Su. Your taste is perfect.”

Maybe she’d naively miss his murderous aura and ask, “Will you bless us?”

His heart would bleed as he replied, “Of course.”

Heartbreaking, bro!

Bai Su felt the world’s malice pressing down.

He couldn’t accept that future. So—

“I just need to eliminate every brat who gets near Su Su…” he decided.

Relief washed over him.

He hesitated, then gently patted Su Su’s head, softening his voice: “Su Su, be good. Don’t be mad. Brother was wrong—I shouldn’t have spanked you.”

Su Su flinched, swatting his hand away with disgust: “Get lost! Pervert!”

…An arrow pierced Bai Su’s heart.

He pushed on, desperate to fix his image: “Su Su, I’m sorry. Truly. You’re a big girl now—I’ll never do this again. Forgive me?”

“No!” Her tone softened despite her stubbornness. “Hmph! Remembering I’m a big girl now? Where was that thought when you spanked me?!”

Bai Su scratched his head. “Sorry… I just lost control. When you called me a husky, am I really that dumb?”

Su Su flushed, remembering she’d started it. She yelled in defeat: “Fine! I shouldn’t have called you a husky! I forgive you, okay?!”

“Hmph! You got a huge advantage but won’t take any loss. So stingy. Can’t you give in to your sister?” she grumbled under her breath.

How unfair. Spanked and still suffering—while he took every advantage without compromise!

Su Su thought resentfully, rubbing her aching butt.

“The days are long! Just wait—I’ll get you back, trash Bai Su!” she vowed.
