"Haaa… this feels like heaven."

Steam curled lazily in the air, blurring the edges of the grand bathroom as I sank deeper into the water.

I wasn't standing in a small hole with a bucket of water. I wasn't sitting in a barrel, hugging my legs. This also wasn't some muddy river that smelled like rotten fish.

No… this is a real bathtub. Correction: a bathtub big enough to fit an entire football team.

The basin wasn't just "large." It was practically a pool carved out of polished marble, its edges trimmed with golden inlays.

Runes glowed faintly along the rim, tiny etchings that pulsed with a magical glow that the innkeeper explained as Mana runes, keeping the water perfectly clean and faintly fragrant. Every ripple here shimmered like liquid crystal under the warm chandelier lights hanging above.

"Ahhhh…" I let myself sink until the water licked my chin. "This… this is living."

The temperature was flawless… warm enough to unknot every stiff muscle, yet not scalding. The best thing? It stayed that way.

No cooling, no bucket refills required, no servants to nag for more hot water. Everything was as automagic as a well-maintained system.

"Mmmm… a glass of wine and a Riddle would make this bliss heavenly."

I traced a finger along one of the glowing runes at the edge of the tub, curious.

The moment my skin brushed the mark, the water warmed by a few degrees. Another tap, and the heat gentled into a lukewarm caress.

"Holy crap… they have a literal thermostat powered by magic."

In my old world, I used to pay insane utility bills just for hot water. But here? Some glowing doodles on marble did all the work.

Why hadn't humanity figured this out centuries ago? Electricity who? Gas geyser, what?

"Medieval fantasy one, modern world zero!"

I leaned back, staring at the mist-softened reflection of myself on the water's surface. Short hair clung damply to my forehead, the usual straight strands heavy with moisture.

That faint green glow that had been hidden within the inner layers ever since I came to this world shimmered when the light caught it. I never gave it much thought, but against the steam it looked almost alive, as if embers were tucked between the strands.

My deep green eyes reflected faintly in the water too, perfectly complementing that hidden glow. Together, they gave me an aura that could almost be called mysterious.

Not that I cared much about looking mysterious. I was too busy stretching in the tub, water sliding down my toned arms and legs.

"Mmmm… I'm indeed hot."

My body wasn't soft— not the delicate, pampered kind noble ladies here probably had.

It carried the lean lines of someone who had worked through long hours, deadlines, and late-night caffeine binges. Even though I'd sat at a desk in my previous life, I'd also been an active person: running to clear my head, swimming when I could, hiking on weekends, and regular lifting.

The result showed here: firm shoulders, a flat stomach that still held traces of definition, thighs with a subtle curve of muscle beneath the skin.

I wasn't bulky; I was streamlined. Practical in fact.

My figure wasn't the type that would win swimsuit contests, uneven in the right areas like Riddle, but it was the kind that could survive. And right now, soaking in a fantasy spa, I appreciate it more than ever.

-Shrrrrrrr…

Water beaded down my collarbone and not-so-modest chest before disappearing into the rippling surface, the herbal fragrance clinging to my skin. For the first time since waking up in this crazy world, I felt clean. Clean and, dare I admit, a little bit sexy.

"Not bad, Aria," I murmured at my reflection. "You scrub up well."

After what felt like forever (and yes, I pruned up like a raisin but no regrets), I finally forced myself to climb out.

A soft towel was waiting for me. Ah, not just soft.

This thing was softer than clouds, smoother than silk, thicker than anything the threadbare laundries of Earth ever produced.

The fabric wrapped me like a hug from a benevolent goddess who whispered, "You deserve luxury, my child."

"Damn…" I whispered, rubbing my cheek against it. "This isn't just cotton. This is… fantasy cotton plus cheat codes."

The towel clung to the water dripping from my skin as I walked into the main room. Muscles still thrummed from the heat, and I felt lighter, looser, almost like a predator fresh after shedding its skin.

That's when I noticed it.

On the chaise near the wide glass window lay a neatly folded outfit. Not my old wolf-hide cape. Not the rough spare shirt Riddle lent me. This was a complete set— prepared while I was drowning in bliss.

'The fairy has good taste.'

It was a two-piece outfit: a soft white blouse threaded with silver accents, paired with sleek trousers in deep midnight blue. A belt of enchanted leather rested on top, its buckle gleaming faintly with protection runes. On the side were boots with a strange metallic shine, clearly not ordinary leather.

I touched the blouse first. The fabric shimmered faintly as it caught the light, light yet strong. Something between silk and armor. It flexed under my fingers, stretchy, yet breathable.

'Magitech textile,' I thought, impressed. 'Fashionable and functional. Earth's luxury brands can go cry in a corner.'

Now, if only they had underwear like the ones I brought from my world– the fairy was impressed by it, so she took it with her for the time being.

'Hopefully I'll get it back cleaned, or better, a new pair in this amazing material.'

I dressed slowly, savoring the texture. Every thread seemed designed to pamper while also whispering, "Yes, you can survive a knife fight in me."

And looking at my reflection in the tall mirror, I had to admit— I looked like someone important. No, correction: like some rich lady from old money.

The towel slipped off my hair, and I shook it out, watching the short strands cling wetly to my temples.

That inner green glow caught the chandelier light again, casting faint emerald sparks across the mirror. Paired with my sharp eyes and toned frame, it gave me the kind of presence I'd never had back in my corporate cave.

'Fantasy makeover successful.'

Now happier, my eyes found the desk by the wall, upon which sat a thick folder bound in gold-trimmed leather. A little embossed label on it read: Traveler's Inn — Services and Privileges.

Fresh and in a new skin, I snatched it up immediately. If I were paying VIP money, I wanted to know exactly how far I could milk this.

The first page listed food options.

Breakfast: fresh bread, eggs, spiced meats, seasonal fruits, and herbal teas.

Lunch: roasted boar ribs, dungeon-harvested vegetables, thick stews.

Dinner: a rotating menu of delicacies, including fish from the Silverlake and desserts crafted with mana-infused cream.

My mouth watered halfway through.

Aside from these, it was mentioned that you can order anything you saw on the streets by mentioning the names, details, or shop locations.

The next page was drinks.

An entire library of wines, meads, and ales. The name of their mixologist was mentioned there: Vice Gillian Bluehorn, probably the hot elf I saw downstairs.

A "moonlight cocktail" brewed from crushed lunar blossoms was their specialty. They also had coffee. Coffee! The description promised "strong enough to wake a lich from eternal slumber."

I nearly teared up. "Bless you, fairy innkeeper. You beautiful winged goddess."

Then came the "Special Services."

Room service. Laundry enchanted to restore clothes to brand-new condition. Daily cleaning by invisible servants (no tipping required).

A library delivery service— books on request, including dungeon bestiaries and reports. Access to a private rooftop garden. And the service one that made me stop and re-read: Personal bathhouse attendants (upon request).

…Okay, that could mean exactly what it sounded like, or maybe it was just cultural translation. Either way, my inner degenerate did a little dance.

The fairy wasn't lying when she said the room had 'special services.' If this is standard VIP, the platinum package probably comes with a free husband. Or a wife. Or both. Equal opportunity service, right?

"Oh hu hu… VIP treatment indeed."

By the time I finished skimming, I was practically bouncing in place. All the suffering, all the blood, all the running barefoot through monster-infested forests— it was worth it. Worth it for this moment, I say.

It was just a few days ago that I appeared in this world, in that forest, attacked and almost killed by those wolves, bloodied, hugging my feet in a fetal position, and now I'm hugging the softest pillow ever.

I flopped onto the massive bed, sinking into silk sheets stuffed with something fluffier than feathers. Then, looking up at the ceiling with a grin, I declared to the universe:

"This, my dear world, is what I call progress."

I stretched across the bed with another grin. "Now then… didn't I have a date to charm— I mean enjoy? Reddy should be done by now.
