Got the consent of the tsundere and the little sun.

Seriously, Gu Luo isn't just a stinky Gu Luo, but also a perverted, siscon Gu Luo.

If she fell asleep at night, he'd definitely grope and knead her chest all over again,

leaving those embarrassingly red handprints behind.

He had zero regard for cherishing delicate beauties.

Gu Ximan twirled her cold tea-brown hair around her fingertips, her rosy cheeks flushing deeper.

Though she complained endlessly in her heart, her body was embarrassingly honest.

Fresh from having her feet washed by Gu Luo—without even drying them—she eagerly flopped back onto the bed, rolling around lazily like a pampered cat.

A sweet, tuneless hum spilled from her lips, brimming with unrestrained joy.

Whether or not she’d sleep over tonight could wait—this Sunday, she had to wear her prettiest outfit.

Oh, and she’d need Xuexue to do her makeup flawlessly, just to utterly bewitch that siscon Gu Luo.

At the thought, Gu Ximan—who normally lacked any athleticism—suddenly surged with energy, executing a perfect kip-up from the bed.

Barefoot, she practically floated across the floor to her wardrobe, even spinning twice and a half mid-step, her hair swaying with giddy delight.

Pure, unadulterated triumph.

The wardrobe door slid open with a whoosh, revealing a kaleidoscope of dresses.

Gu Ximan scrutinized each one, muttering under her breath:

"Too flashy... nope."

"Too long... nope."

"Too short... well... maybe? That pervert Gu Luo would—no, definitely—love it..."

"For stockings... white ones, since he’s obsessed... Oh, and I’ll block all those white-stocking influencers in his phone. Hmph! From now on, he’ll only gaze at this goddess..."

"Shoes... the ones he gave me are cute enough..."

"Hair... high ponytail? Twin tails? Or maybe curls? But loose waves might look more mature..."

She paused mid-ramble, struck by a realization: once they made things official, things would progress. Home wasn’t private enough—maybe a hotel?

Aunt Luo’s family owned a luxury one... Could she, as the youngest heiress, get a free stay?

Tch—get a grip, Ximan!

"Lingerie... my current sets are too childish. Saturday, Xuexue and I’ll hit the mall for something seductive... That’ll finish off siscon-perv Gu Luo."

"La la la~~~"

Humming, Gu Ximan reveled in life’s sweetness, the very air tasting like honey.

So Gu Luo did feel the same.

Just as Xuexue said—they were a mutual crush.

Still, their bond was unique. Raised together, calling him "big bro" for over a decade, their bond ran deeper than blood. Switching from siblings to lovers? Awkwardness was inevitable.

Hence the hints instead of outright confession.

Remembering Xuexue, Gu Ximan gasped—she’d almost forgotten to share the news!

Clutching her chosen dress and stockings, she bounced back to bed, video-calling Lu Xuexue.

The screen soon lit up.

"What’s up, Manman?"

Fresh from a shower, Lu Xuexue’s cheeks were dewy-pink, her damp hair tousled as she towel-dried it.

"Xuexue, come lingerie shopping with me Saturday!"

Gu Ximan’s eyes crinkled into crescent moons, barely containing her glee.

"Sure!"

Xuexue tilted her head, studying her friend’s radiant face. "You seem extra happy. Good news?"

"Hehe."

Gu Ximan twirled her hair, sugar-coating her words: "Xuexue, stinky Gu Luo’s confessing to me this Sunday."

"Eh?!"

Xuexue froze mid-towel, lips parting. "Gu... Gu Luo’s confessing?!"

"Mhm~"

Gu Ximan flopped onto her pillows, holding the phone aloft, her voice syrupy:

"What can I say? This goddess is irresistible."

She then recounted Gu Luo’s foot-washing service and every loaded hint.

Xuexue listened, cheeks burning, fingers knotting her hair. Every analysis clicked—mentioning their future trio, praising a girl "as lovely as Manman"—it had to be love.

How enviable. If Gu Luo ever confessed to her, she’d be sleepless for a week.

Noticing Xuexue’s wistful blush, Gu Ximan grinned. "Saturday, we’re both buying sexy lingerie."

"Huh?"

Xuexue blinked as her friend barreled on:

"I’ll drag Gu Luo to a hotel... Then you’ll ... We’ll like we planned... and finally together..."

Each scandalous detail turned Xuexue scarlet, ears burning, yet she leaned closer, hanging on every word.

———

Meanwhile, the living room.

"Pfft—HAHAHA!"

Luo Shuling curled on the sofa, howling at the TV, her laughter ringing through the room.

Gu Luo, freshly escaped from Ximan’s room, exhaled in relief. Grabbing chips and yogurt, he joined Shuling.

"Gege, this show’s hilarious!"

Without thinking, Shuling plopped her toned, sun-kissed legs onto his lap, wiggling her toes to the upbeat soundtrack.

Cough.

Gu Luo side-eyed the brainless sitcom—perfect for his airhead sunshine of a sister—while his gaze definitely didn’t linger on her golden, endlessly distracting thighs.

Then, he opened the bag of potato chips, picked one up, and brought it to Luo Shuling's lips.

"Ah~~~"

Luo Shuling's eyes remained fixed on the TV, but her mouth obediently opened to take the chip.

"Crunch, crunch..."

"Haha..."

She giggled while chewing, looking utterly silly.

So cute, so clueless, adorably dumb.

Being around this little sunbeam, Gu Luo felt his heart instantly settle into tranquility, as if enveloped in a serene, timeless bliss. He continued feeding her, one chip after another.

Luo Shuling ate happily, and he fed her even more happily—like nurturing an adorable little hamster.

She didn’t keep all the snacks to herself, either. Every now and then, she’d offer Gu Luo a half-bitten chip. Though the gesture was intimate, it carried no hint of ambiguity.

She was simply the sweetest little sister.

After what felt like forever, as the chip bag neared its end, Gu Luo suddenly spoke softly, "Shuling, there’s something I need to tell you."

Right now, she was the only one in the family who didn’t know about his plan to confess to Luo Shuning on Sunday. Getting her approval would make everything complete.

"Hmm? What is it?"

Luo Shuling pulled her gaze from the TV and turned to Gu Luo, her big eyes blinking, long lashes fluttering slightly.

For some reason, staring into those clear, innocent eyes, Gu Luo felt inexplicably shy. Emotions he’d kept buried surged up, making him awkward as a first-time lover. He chuckled awkwardly.

"Well, I... I’m going to confess this Sunday."

"Huh? To me? Of course I’d say yes!"

She even blew him a playful kiss.

"......"

Gu Luo was momentarily speechless but didn’t take it seriously. Amused, he clarified, "No jokes... It’s... it’s to Shuning."

"Shuning? Of course I’d say yes!"

She blew him another kiss.

"Pfft."

Gu Luo couldn’t help but laugh, genuinely delighted by her silly, carefree nature. He truly adored this airheaded little sister.

After a pause, he reached out and ruffled Luo Shuling’s soft, ear-length hair, smiling faintly. "I’m glad you approve."

"Of course I do!" Like a kitten relishing a head pat, Luo Shuling leaned into his touch, beaming.

"Shuning and you are a perfect match—talented and gorgeous. I fully support it!"

Hearing this, warmth spread through Gu Luo’s chest. He gently pulled her into a hug, breathing in the faint, refreshing lemon scent clinging to her—soothing and comforting.

Then, he whispered by her ear, "Thank you, little sunbeam."

He was truly grateful she hadn’t questioned Gu Ximan’s opinion, or their step-sibling dynamic, or anything at all—just offered her wholehearted blessing without hesitation.

This easy, joyful feeling—among all four sisters, only his little sunbeam could give him this.

"No problem, bro."

Luo Shuling wrapped her arms around his waist, squeezing lightly, and grinned. "Oh, by the way, after Ximan came back, she showed me tons of your childhood photos. Want to see Shuning’s? She was seriously adorable."

"What a coincidence—Shuning and I are planning to revisit those tomorrow."

"Really? Then you’ve gotta see them all! Shuning and I were like tiny princesses—ridiculously cute."

With that, she let go of Gu Luo, tilting her head slightly. Her eyes curved into crescents, her smile radiant as sunshine.
