Second half of the second term.

Ever since the day his soul got completely stolen by me during the sports festival relay, Yuuma had undergone a dramatic job change—from hated rival to the captain of the “Shizuku Onee-sama Fan Club.”

"Shizuku Onee-sama! I offer up my pudding from today’s school lunch as well! So please, teach me once more the secret of that cornering that sliced through the asphalt!"

"Just eat your own pudding. And I’m just running, that’s all."

At the classroom entrance, Yuuma looked like he was about to kneel on a branded handkerchief, while I brushed him off half-heartedly with mild exasperation.

And Anju glared at the scene with the face of a demon.

This had become the everyday routine of Class 1-1 lately.

"Hey, Yuuma-kun! Don’t get so familiar with Nanase-san! And more importantly, someone as uncultured as you calling her Onee-sama is worthy of death!"

"Shut up, Hojo! I saw true ‘manliness’ in Shizuku Onee-sama’s running! She’s my master of the soul, transcending gender and family status!"

...Honestly, both of them were noisy.

In this insane world, the “rare male child” who should be at the top of the class and the “noble young lady” were constantly having catfights over standing next to a single girl 'me'.

This absurd situation was steadily wearing down the mental state and stomach lining of our homeroom teacher, Suzuki-sensei '30s, married with children'.

I felt like her gray hairs had increased rapidly lately.

But while all that chaos swirled around me, my mind was already somewhere else—in a vast, silver-white world.

December. First day of winter break.

From early morning, I was in the Nanase household living room, lovingly and carefully polishing “it.”

"Alright... no rust on the edges, and the hot wax is perfectly set."

In front of me was the children’s snowboard my mom had bought for me 'well, after I made a deal to get perfect scores in every subject during the second term'.

Compared to the pro model board I used in my previous life, it honestly felt like a toy.

But for my current slender build and leg strength, this was the best option.

"...Shizuku. You really are a strange child."

My mom, who was preparing winter gear nearby, let out an exasperated sigh as she watched me hugging the board in the middle of the living room and even rubbing my cheek against it.

"A normal six-year-old girl would want a cute Santa dress or a big playset around this time. Why are you voluntarily throwing yourself into subzero snowy mountains?"

"Mom, you just don’t get it. The snow mountain is my battlefield and my ultimate playground. That feeling of leaving gravity behind... it’s addicting."

"You talk like some veteran rider... Just don’t do anything dangerous, okay?"

Even as she said that, she watched my practiced maintenance work 'scraping off excess wax with a scraper and finishing with cork, like a pro' with a complicated expression—somewhere between admiration and suspicion that I might actually be the reincarnation of a snow spirit.

And so, the first slope of the season.

The moment I got off the lift at the summit, I inhaled the crisp, freezing air deeply.

"This is it. That sharp feeling in the back of your nose... makes you feel alive."

I sat down on the snow, tightened my bindings with practiced ease, and set my goggles in place.

My wear was a sporty black-and-white design focused on mobility.

And beside me—on one side, Anju, who had come fully equipped in high-end winter gear 'a premium kids outfit with white pom-poms' after hearing about my “snowboard debut.”

On the other, Aoi, who had shown up in fluffy pale pink winter wear with the resolve of “If I’m with Shizuku-chan, I’ll even go to the North Pole.”

"S-Shizuku! I’ve taken indoor ski lessons, but... going down something like this—this cliff—there’s nothing like this in Hojo family education!"

Anju’s knees trembled as she looked down at the beginner slope, on the verge of tears.

No matter how much she tried to act tough, for a six-year-old, this height was pure terror.

"Shizuku-chan... can I hold onto your back tightly while we go down?"

Meanwhile, Aoi’s instincts as a yandere were completely overpowering her fear, focusing entirely on clinging to me.

Seeing the two of them, I grinned boldly beneath my goggles.

"Princesses, just watch from somewhere safe. I’ll show you what real ‘speed’ looks like."

Leaving behind that cheesy, full-on ikemen line from my previous life, I pointed my board down the fall line 'toward the valley' and launched myself down the slope.

"Eh—Shizuku!?"

"Shizuku-chan!?"

Their voices echoed behind me, but my focus was already locked onto the snow.

The countless repetitions of weight transfer from my previous life.

Even with a six-year-old body, that extreme lightness let me glide as if caressing the snow.

Seamless carving turns from heel side to toe side.

With the satisfying sound of edges biting into snow, powder sprayed up as I carved sharp lines across the untouched white canvas.

'This is the best... This speed, this G-force...'

The sensation of snow after so long sent adrenaline surging.

Spotting a small dip 'a wave' in the slope, I charged straight into it.

Using the board’s rebound and initiating upper body rotation—an Andi 540.

One and a half rotations in the air, landing perfectly.

Then flowing straight into shifting weight to the nose 'front of the board', bending it and spinning along the snow—a nose butter 360.

A series of pro-level ground tricks unimaginable from a six-year-old’s small frame.

The adult skiers and snowboarders nearby stopped one after another, stunned by the otherworldly performance.

"...No way, is that kid a pro junior rider?"

"Look at that black ponytail... her riding is insanely cool..."

"A boy—no, a girl!? Her proportions are crazy!"

Ignoring the murmurs, I rode all the way to the base in one go.

Slamming on the brakes and spraying snow everywhere, I pushed my goggles up onto my forehead.

"Ahh, I’m back!"

The soul of my past life as a snowboarding addict 'to the point of studying abroad in Canada just for longer snow seasons' roared with joy.

My brain floated in a sea of adrenaline as I breathed out white air, cheeks flushed from the cold wind, and looked back up the mountain with a wide grin.

And there—was the red-haired noble girl, completely robbed of her soul by my performance, sitting collapsed on the snow with her legs giving out.

Anju’s face was boiling for reasons unrelated to the cold, her eyes turned into full-on hearts.

And beside her—was Aoi, staring as if burning my image into her retinas, muttering something dark under her breath with dangerous intensity.

'That’s supposed to be only my Shizuku-chan... I don’t want other pests to see her, I don’t want them to see her, I don’t want them to see her…’

Aoi’s special-grade yandere radar was now emitting killing intent even toward the surrounding spectators.

'Ah... yeah, that might’ve been a bit much. Got carried away after so long. Well, if they understand the charm of the mountains, that’s fine.'

Cracking my neck casually, I headed back toward the lift.

Completely unaware—that my “unconscious snowboarding heroics” had just poured a massive tank of gasoline onto the heroines’ possessiveness, igniting an overwhelmingly heavy love that could melt even the winter cold itself.
