CHAPTER 5: Noona Is Not What She Seems

---

Arrival of the Elegant Stranger

In a peaceful market town far from Raiko’s crashing failures…

A woman wandered in—

Dusty, dignified, quietly terrifying.

Long coat. High boots. A scarf like she escaped from a romance novel.

Calm, unreadable eyes. Lips too perfect for this chaotic setting.

Locals whispered:

> “A noble lady in hiding?”

> “A runaway duchess?”

> “A new cult leader?!”

In truth, Noona just wanted a bath. And directions to a hot meal.

---

Enter: Yu-Riella, Chaos Merchant Extraordinaire

A voice like a squeaky trumpet pierced the town square.

> “MISS! WAIT! You look lost! Are you a princess?! YOU’RE GLOWING!”

She was round. Loud. And unstoppable.

Yu-Riella.

22 years old.

Talked faster than she could think.

Dressed like she rolled through five different festivals and stole accessories from all of them.

Her arms were full of bangles, scrolls, and random artifacts she swore were “limited edition.”

She gasped dramatically.

> “Your skin! It’s so smooth! What serum do you use?!”

Noona blinked.

> “…Olive oil. And discipline.”

Yu-Riella almost collapsed from shock.

---

Mistaken Identity

Instantly, Yu-Riella decided:

> “I MUST protect this gentle lady on the run!!”

> “I’ll get you a job! Help you blend in! Teach you how to lie to guards!”

> “You can stay with me! I’ll be your big sister now!”

Noona tried.

> “I’m not—”

> “NO NEED TO THANK ME!”

> “Now quick—what cleanser do you use?! Mine cost 30 gold and just made me shinier!”

---

The Truth Hits Like Bad Foundation

Days passed.

Over tea, Yu-Riella asked casually:

> “So how old are you anyway, kid?”

Noona sipped calmly.

> “Thirty.”

Yu-Riella choked.

> “T-THIRTY?!”

> “YOU’RE OLDER THAN ME?! I’ve been calling you ‘kid’ this whole time!”

Noona’s voice was flat as ever.

> “Yes. And I didn’t correct you. Because it was funny.”

Yu-Riella clutched her chest like she'd been betrayed by her own moisturizer.

> “Then what is your skincare?! Your water brand?! Your bloodline?!”

Noona leaned in like a skincare sensei:

> “I eat clean. Sleep early. Don’t chase men. And wear sunscreen.”

Yu-Riella: passes out from enlightenment.

---

An Unbreakable (and Slightly Deranged) Bond

From that day on, Yu-Riella:

Declared herself “Noona’s Eternal Lil’ Sis™”

Demanded weekly skincare lectures

Roasted anyone who dared flirt with her “Big Sis”

Tried to sell fake beauty scrolls based on Noona’s lifestyle (“10 silver per scroll, 100% goddess-certified!”)

Noona?

She didn’t mind.

In fact, she enjoyed the chaos in silence.

Because in a strange new world full of monsters and idiotic systems…

…it was kind of nice to be needed.

Even by a migraine in human form.

> — Author’s Note — Thanks for making it this far into the chaos. This is just the beginning of Raiko and Noona’s very married journey through bad decisions, summoned cults, and emotional guitar solos.

Chapter title references are 100% serious. Probably.
