Brother's Cold Rejection and Sister's Teasing Embrace
My oldest brother was quite the stoic type. With his rigid personality, he always gave off this vibe like he was reluctant to deal with people. Those around him often called him cold-blooded, but he never seemed to care. He was handsome, aced his studies, and was good at sports too—no weaknesses, a perfect hexagon of a guy. That's why I always felt this subtle distance from him.
But... that aside, he'd always quietly looked after me and my sister with that same stoic face. He was affectionate and kind. At least, that's the Kim Ji Hoon I knew. I liked that brother. So... I thought he'd accept me, even in this state, to some degree.
But apparently, that was just my desperate personal wishful thinking.
Bro, what's wrong?
"What do you mean, what's wrong...?"
His gaze naturally shifted to my face. Then it traveled down from my head, pausing at my skirt.
"...Sorry."
After scanning me for a few short seconds, he turned his back to me. That was all he said—a flat, monotonous apology.
"Ah, ahhh..."
I felt like I had to say something, so I moved my mouth. I strained my throat desperately, but all that came out was the same pathetic babble.
Frustrated, I hurriedly scribbled on my whiteboard and reached out toward him. His clothes, anything—I just wanted to grab him before he turned away completely.
But against my wishes, he'd already headed up to his room on the second floor long ago.
"Ahhh..."
I was left all alone in the entryway, stranded.
In my emptiness, my eyes drifted to the whiteboard still in my hands.
Don't go.
The crooked scrawl stared back at me. I never realized not being able to speak could be this inconvenient.
"Hic..."
Negative emotions blurred my vision. No. I'd decided not to cry in front of my family anymore.
I clenched back the tears that felt ready to burst at the slightest touch and forced strength into my trembling shoulders.
"Hm? What're you doing out here instead of going in?"
I quickly schooled my expression at the sound of the front door opening and my sister's voice.
I just said hi to Bro. Guess he had something urgent—he went up to his room first.
"Ji Hoon oppa was here? Was there anything... special?"
What're you talking about?
"You know, like some manga-style reaction now that your little brother's turned this cute?"
My sister overreacted dramatically, her hand drifting casually to the hem of my skirt. Then she flicked it upward just a bit.
The skirt I was wearing fluttered up precariously right in front of me.
"Eek?!"
Startled by her sudden move, I dropped the whiteboard I was holding.
To hide it somehow, I grabbed the hem and pressed my hands down. When I came to, I was instinctively pressing my legs together in that classic girl pose.
"Your reaction is too delicious! Oppa would've passed out if he'd seen that!"
"Eeeeek!! Eek!!"
Face crumpling in misery, I lunged at her. But with our height difference—a full head taller—and my powerless body, I was far too frail to overpower her physically.
"That's why I told you not to force yourself into a skirt. You know how precarious you looked from the hospital all the way home, right?"
What was she talking about? From the hospital to getting home, I'd been hyper-vigilant to keep anything from peeking under my skirt.
The overly tight women's underwear felt weird against my skin, and the empty sensation spreading from my legs inward was creepily unpleasant. So I'd thought I'd been careful...
"You haven't looked in a mirror yet, have you?"
"Uuu..."
I nodded quietly in affirmation. She let out a deep sigh and pulled out her smartphone.
"Caught you off-guard—snap!"
"?!?!"
Without a moment's hesitation, she started snapping photos.
What the—?!
'What the hell is she doing all of a sudden?!'
Panicking at being photographed, I covered my face with both hands as best I could. She just said it made me cuter and kept snapping away wildly.
"Phew, satisfied."

You're insane. Pervert. Just hold your breath for a few minutes.
Gulping for air raggedly, I scribbled whatever came to mind.
She snatched my hand holding the whiteboard like it was nothing.
"Uh?!"
My body lurched forward toward her. Looking up at her face in shock with wide eyes, our gazes met—and she grinned from ear to ear.
"I told you, right? Once you're discharged, I'm gonna dress you up all I want. Get ready."
"?!?!"
Suddenly? I vaguely remembered her saying that teary-eyed during our first visit. I'd figured it was half-joke to lighten the gloomy mood...
'Wait... she was serious...?'
"Get ready."
No sooner had she said it than her grip tightened on my wrist.
"U, uweeeeeek!!!"
I thrashed desperately to escape her grasp, but it was no use. I'd always been her plaything for pranks, but I'd never lost to her in strength before.
In the past year, my muscles and power had weakened a lot, and my whole body had become slender and delicate. I'd hidden it under baggy clothes before, but now in fitted women's attire, it was clear: my body was that of a frail girl.
A girl so fragile I couldn't even match her physically anymore...
"As your senior, I'll teach you. Like it or not, you braced yourself for this, right?"
"Hiiiiiik!!!"
Her final "get ready" sounded ominously resolute. My scream echoed like a pig dragged to slaughter, and with that, her door quietly clicked shut.
**
"Phew, I always wanted a little sister, but I never dreamed it'd come true like this."
She looked utterly pleased with herself.
"...Huh?"
I could only tilt my head in confusion, wearing a dumb expression in front of her.
The moment the door shut, she'd bluntly ordered me to strip. The atmosphere was so coercive I couldn't refuse—she even added that she'd do it herself if I didn't, leaving me flustered.
"Uuu..."
With no way to escape, I squeezed my eyes shut, tears welling up.
I unhooked the skirt at my waist and let it slide down, gliding over my skin to pool at my legs.
"Here, try these on."
Honestly... I'd expected something weird after that. But contrary to my fears, she just casually tossed me some normal clothes.
When I opened my eyes, they were definitely women's clothes—no skirts in sight, even if I squinted.
"You ever seen a girl who only wears skirts? If it's uncomfortable, just wear pants like normal."
She gave me a frustrated look, then flicked my forehead lightly.
A sharp thwack! rang out from my forehead.
"Ahhh..."
Tears pricked from the pain. It was just a little impact, but it hurt more than expected.
"Don't wanna wear a skirt? Then don't. No one's forcing you. Of course... underwear's non-negotiable, so you'll have to get used to that part..."
Her gaze dropped to my lower half, clad only in underwear. Following it, my eyes went down too.
There it was: plain white women's underwear fitting my new body perfectly. Seeing that pure, girlish white skin under it, I knew it intellectually, but the disconnect wouldn't fade.
It felt so wrong. Wearing women's underwear this naturally...
"H-Hurry up and try on the clothes already! You're embarrassing me just standing there!!"
After a few seconds of awkward silence, her face flushed as she chucked a pair of pants at me—something casual enough to wear.
"Ahhh?!"
No time for self-loathing in front of her. I took the pants without resistance and changed.
Like this?
"Yeah! Skirt's cute, but pants suit you great too! You've always been a good clothes horse—even back when you were a guy?"
Why emphasize the guy part? Back in middle school, she'd occasionally drag me into cross-dressing pranks, but I'd brushed it off as her mean-spirited teasing.
Remembering that soured my expression.
You really are a pervert, sis.
"Dressing my little sister in girl clothes makes me a pervert?"
Little sister. Hearing it so directly didn't feel real at all. No matter how much I steeled myself, accepting my identity in an instant was impossible.
Switching to women's clothes... this was probably just the beginning. Soon I might have to call Bro "oppa" and Sis "unnie." I worried if I'd handle that whole process okay.
"Anyway, let me be clear: you're really pretty. Most girls couldn't hold a candle."
Out of nowhere, she shoved her smartphone in my face. The screen showed the photo she'd just taken—now her wallpaper. Me, embarrassed while my skirt was flipped up, captured perfectly.
My face still looked like my old male self... but no matter how you sliced it...
This was unmistakably a girl. A girl.
