My Stepmother Brought Three Adopted Sisters, and I Have a Doting Sister System Chapter 158

Stepping out of the Lucky Snow City, the sunlight outside bathed Gu Luo in just the right warmth. He took a deep breath and sighed sincerely, "Ah... finally warm again."

Earlier in the shop, while sharing a grape taro ball drink with Gu Ximan, he had inexplicably felt a creeping chill around him. Now, outside, his whole body felt much more at ease.

At that moment, Gu Ximan teased with a grin, "Dummy big bro... are you getting weak? I heard guys who can't handle the cold..."

Before she could finish, her forehead was met with a solid flick.

"Ouch..."

She reflexively covered her forehead, her cheeks puffing up in annoyance, looking utterly adorable.

"What kind of nonsense have you been learning lately? No good at all." Gu Luo shot her an exasperated glare.

This silly girl had actually started making jokes like this now.

Besides, he was strong and healthy—how could he possibly be weak?

Did she even understand the prestige of lasting thirty-four minutes and fifty-two seconds?

Plenty of pilots crash within the first minute, you know.

"Dummy big bro, you’re one to talk! Weren’t you just about to comment on my..." Gu Ximan started, only to be cut off again.

"Alright, alright, you win, you win."

Gu Luo promptly surrendered.

He really didn’t want to discuss these things with Ximan.

It just felt awkward, as if some unspoken boundary had been crossed.

"Hmph."

Seeing this, Gu Ximan let out a light snort, her lips curling down slightly as she secretly clenched her small fists.

She was already testing the waters, step by step.

But no rush—she had time.

There was a long road ahead.

No matter what, she could always stay by her dummy big bro’s side.

One day, she’d crack that thick skull of his.

So dense!

Beside them, Lu Xuexue smiled without a word, wholly absorbed in shipping her best friend and her crush.

Gu Luo, meanwhile, sighed inwardly. He was now absolutely certain the two girls hadn’t made up.

Before, Gu Ximan would’ve affectionately held Lu Xuexue’s hand, not leaving her out like this.

But today, aside from a brief moment of enthusiasm at the start, she’d been deliberately avoiding her.

What kind of conflict could it be?

Though puzzled, Gu Luo still smiled and said,

"Alright, let’s go sign up first. Time to show you your big bro’s real skills, Ximan."

"Hmph, if you lose, you’re in for it, dummy big bro!"

Gu Ximan waved her dainty fist with exaggerated seriousness.

Inside, though, she was buzzing with excitement.

Her mind was filled with visions of the upcoming princess carry.

Hehe... dummy big bro’s princess carry...

She had to give the event planners a big thumbs-up.

"Don’t worry, if I lose, I’m at your mercy." Then, Gu Luo suddenly shifted gears with a grin, "But what if I win?"

"Even if there’s no credit, there’s still hard work, right?"

Hearing this, Gu Ximan didn’t hesitate for a second before declaring, "If you win, this beauty will give you three kisses!"

At the same time, her gaze subtly flickered toward Lu Xuexue’s face.

But the girl remained in her fangirling bliss, completely oblivious to the hidden message.

Once again, Ximan’s punch landed on cotton.

Gu Ximan was internally screaming, nearly blurting out the secret that they weren’t actually related by blood.

"Hard pass."

Gu Luo waved his hand dismissively before changing the subject.

"If I win, you can wash my feet three times instead. Deal?"

At first, Gu Ximan bristled at his rejection, but upon hearing the alternative, she paused in thought.

Washing dummy big bro’s feet...

That didn’t sound bad either...

Come to think of it, his feet were actually quite nice—pale, well-shaped, with clean lines.

Wait, wait, what am I thinking?!

Startled by her own thoughts, she nearly sat bolt upright.

Was she... a secret foot enthusiast?

Her cheeks flushed slightly, but she feigned composure and huffed,

"Fine, it’s a deal."

"You’re really agreeing?" Gu Luo’s expression turned odd.

For some reason, Ximan seemed a little... off.

But he couldn’t quite put his finger on why.

"Hmph, a beauty’s word is as good as gold."

Gu Ximan lifted her chin, putting on a bold front while scheming inside:

‘Just watch how this beauty slowly reels in that thick-headed dummy.’

If she couldn’t say it outright, she’d reshape their relationship bit by bit through everyday moments!

‘Why should I let anyone else have dummy big bro?!’
