Episode 36
Even though it had been nearly two months since we’d last seen each other, there was nothing like a tender reunion between my sister and me.
“So let me get this straight.”
Yu Seong-ah crossed her arms and looked down at me.
“You’re asking me to teach you how to dance right now?”
“……Yeah.”
“……”
The silence didn’t last long.
“Pfffahahahaha!!”
Yu Seong-ah rolled off the sofa.
“Wow, that’s insane! I’ve lived long enough to see everything now. What, you can’t do it?”
“……Yeah.”
“I knew it! How could you possibly manage it with that body of yours!”
……This woman showed no mercy even to her own blood brother after all this time apart.
“I…… I can memorize the movements no matter what.”
“But?”
“I don’t have the fundamentals.”
“Oh-”
Yu Seong-ah’s eyes gleamed. It was a very dangerous signal.
“Man, I’m really busy these days.”
She had to know. Much as I hated to admit it, Yu Seong-ah was the most sought-after choreographer right now.
“Do something cute for me after all this time.”
“Ah, come on-”
Right. Yu Seong-ah had never been one to refuse a request.
“Hey, I’m your sister.”
But there was never anything free about it.
“I’m almost an adult now, though.”
“Oh- So what?”
And it was always extremely expensive.
‘Is this what a tyrant is?’
“If you don’t like it, don’t do it. Where in the world does anything come free?”
“No, of course not. I’ll do it.”
In front of her, human dignity crumbled far more easily than one might expect.
“That’s what I thought. Come on, try this one for old times’ sake.”
“Ah, that one’s kind of-”
“Tsk, your expression is ugly.”
I quickly rearranged my face.
“……Should I sing along with it?”
“Hey, look at you picking up some sense since becoming a trainee? Of course.”
In the end, here I was—a man with the mind of a twenty-nine-year-old—
bouncing in the middle of the Practice Studio.
[I love you-u-u
When I see you, I tremble
No no no no-]
What Yu Seong-ah meant was none other than ‘NO’ by Judy, the song known as the national cutesy anthem.
Even though I hadn’t danced to it for nearly ten years before my regression, my body moved instinctively the moment I heard the song.
‘This is how scary brainwashing can be.’
“There we go! Hey, your dancing really has improved?”
Yu Seong-ah clapped her hands together, clearly delighted.
“Right, my beloved little brother is pleading like this—your sister has to help.”
“Thanks!”
“Thanks……?”
“I’m, I’m truly grateful.”
Only then did she smile with satisfaction.
“Okay. You said two weeks, right? Let’s destroy those fundamentals over the next two weeks.”
And so I walked straight into Yu Seong-ah’s tiger’s den all on my own.
Two hours later.
“Again!!”
Four hours later.
“What is wrong with your body, seriously?”
Would you believe me if I told you I’ve been stuck on a single Wave movement for four hours straight?
On the first day, I’d tried to avoid using the Time Travel Clock and the editing function as much as possible. I needed this to sink into my bones; otherwise, I wouldn’t be able to use it properly later.
But that was my arrogance.
“Is this a person, or a squid?”
Yu Seong-ah grabbed my arm and shook it back and forth, her fingers kneading the muscle.
“Come on, even so, I’m not quite a squid, am I?”
“Look, you’re my brother, but honestly, the fact that you made it into the Debut Group makes me wonder if it was rigged.”
‘Is this woman secretly one of my false critics online?’
“That’s enough for today.”
“Already? That’s a shame—”
I barely suppressed the corners of my mouth from twitching upward.
“We’ll do more Wave tomorrow. Now we’re moving on to Step Basics.”
“……?”
“You weren’t actually thinking of stopping here with those skills, were you?”
The basics hell began anew. My legs started trembling more and more.
‘Why isn’t Yu Seong-ah getting tired?’
After about ten hours, sweat pouring down like rain was no longer the issue. By now, there was no reason, no emotion left—I’d become a machine that simply danced.
I’d reached a state where my feet moved on their own, as if I were wearing red dancing shoes and couldn’t stop even when standing still.
‘It’s only been one day, and I’m supposed to keep this up for two weeks?’
The world spun before my eyes. But I could still hear Yu Seong-ah’s roar from somewhere.
“Get up!!”
I didn’t want to create items during practice. But if I could, I would’ve made a Time Travel Clock and just jumped forward two weeks.
Then, as I lay sprawled on the floor gasping, the status window glimmered before my eyes.
[S: Items are not for shortcuts!]
‘Oh, how grateful I am for the advice!’
I kicked at the empty air. The moment Yu Seong-ah’s gaze reflected in the mirror turned toward me, I mumbled.
“……My legs are numb.”
“Are you rested? Now get up.”
Just as the saying goes—basics are always the hardest. Step Basics could never be overlooked. It would’ve been easier to do the Signal Choreography a hundred times over.
It was a moment where I starkly confronted how superficially I’d been dancing all this time.
At times like that, I’d recall Song In-hyeok’s evaluation.
[You might not realize it now, but after debut, there won’t be time to learn much of anything. At that point, I’m honestly not confident Yu Seong-woo can keep up.]
An idol has to excel at performance. And performance, ultimately, comes down to dance—the most visual element.
I’d barely maintained sixth place, but if my dancing didn’t improve by the next round, I’d drop out immediately.
“Ugh…….”
I dragged myself up on legs that felt like they were dying.
And a week later, I finally cried.
“Whoooooa…….”
……Truly.
“Huh?”
Yu Seong-ah, who’d been counting the beat, startled.
“Are you crying?”
“I’m not crying.”
“You are.”
“I’m not!”
“Wahahahahaha!!”
Then she laughed like she’d gone mad.
“Wow. I haven’t seen you cry in forever!”
“…….”
‘Is this woman actually psychotic?’
Once the tears started, they didn’t stop easily. It had always been that way since childhood. So I’d even cried through dances on stage.
“Can I film this?”
“I’ll die.”
“This is for your sister—”
After laughing for a while, Yu Seong-ah tossed a towel at me.
“Hey.”
“What.”
“Are you done crying?”
“…….”
“If you’re going to quit, quit now.”
For the first time, his voice was completely devoid of playfulness.
“You think I can’t feed and support one person?”
“…….”
“What were you thinking, doing something so reckless…….”
Suddenly, his throat tightened.
“I want to do well too…….”
“What am I supposed to do when my body won’t cooperate!”
His true feelings spilled out.
“You don’t understand anything.”
And far more pathetically than he’d intended to admit.
The moment the words left his mouth, he knew he’d lost it.
Yu Seong-ah was walking toward him. This was at minimum a hair-pulling session.
“No, wait. I didn’t mean—”
Behind her, a dark aura seemed to materialize.
“I’m sorry, I’m sorry. I wasn’t thinking straight for a moment—”
Snatch.
Her hand came up toward his head.
“Huh?”
Could this be… comfort?
Yank.
“Aaaagghhhh!!”
He thought his hair was being ripped out by the roots.
“You need discipline before you need dance moves.”
“Ow, ow!”
“And if you can’t even handle this, what? You’re going to be an idol?”
“Noooooo!!”
That day, he finally understood.
“If you’re going to throw away your studies to become an idol, you’d better do it properly!”
Yu Seong-ah was no tsundere.
“What? You didn’t know? That’s insane!”
She was just a tyrant.
“A brat with only a few weeks of practice, and you think you can rub shoulders with me?”
And worse still.
“You think dance is a joke? Huh? Funny to you?”
A dance-obsessed tyrant.
The criminal received her sentence—not execution, but reeducation.
Yu Seong-ah’s discipline sessions continued long afterward, leaving him drained of tears and snot. Despite being only nineteen years old, his mental age was twenty-nine, and even that felt inadequate for what she put him through.
Whenever he faltered during practice, a Finger Stick would unerringly jab into him.
‘Where does she even find these things?’
“All right, we’ll watch episode 2 and continue after.”
He couldn’t believe it. A whole week had already passed since he’d entered Secluded Training?
Time definitely moved more than twice as fast in this Practice Studio.
“Hey, who was the one who collapsed anyway?”
“Check the broadcast.”
Silence fell. That was strange—now wasn’t the time for quiet…….
Sure enough, Yu Seong-ah’s eyes weren’t smiling, only the corners of her mouth lifted as she looked down at him.
“Your answers are getting short?”
A chill ran down his spine.
“……No, that’s not it. It’s just a bit difficult to share due to confidentiality clauses. I absolutely wasn’t trying to talk back to you.”
“All right.”
His brain had glitched from getting used to time without Yu Seong-ah around. He’d need to stay sharp from now on.
* * *
Boys Code kept the buzz from episode 1 alive through episode 2 by posting new teasers daily to their official account.
Behind-the-scenes photos and videos of the trainees were released, drawing in more fans.
Su-jin, who’d become a fan after episode 1, ended her initial skeptical phase and created a new SNS account.
Orthodontia @orthodontia 2 minutes ago
Orthodontia, thanks to you I looked up how to spell “orthodontia” in English for the first time in my life. I love you.
-It’s so funny how you just throw around “I love you” like that
└He’s my new bias and husband
└Here she goes again
A trainee whose name and age were still unknown. The only confirmed information was that he was at least nineteen, going by what Kang I-ryul called him.
“With no information at all, doesn’t that just make you more curious?”
Episode 2 finally began.
The trainees’ genuine reactions upon facing the massive set were broadcast raw.
[Production Staff: The stage size varies depending on your Code, and for C Group, the first verse will proceed with the lights off.]
[Murmurs ripple through the venue]
[Code 18: Honestly…… if it was going to be like this, I wondered why we even practiced.]
[Code 20: It was really cramped in there, you know? There’s barely space to extend your arms, and they completely cut the first verse…… it’s frustrating.]
“That’d piss anyone off.”
But Su-jin’s eyes were searching for only the trainee with braces.
“Oh, here he comes.”
[※Debut Group Code trainees were provided the benefit of using special items individually.※]
“Did he come up with that scar makeup himself too?”
Orthodontia @orthodontia 1 minute ago
A guy with good self-awareness is attractive, how did he know the scar makeup would suit him so perfectly?
By the time Su-jin had memorized the song through repeated takes, the problematic scene aired.
[Just as the final ending fairy sequence finished filming, a loud crash came from somewhere.]
[Crash—!]
[Startled trainees and production staff.]
“Did someone collapse?”
[Production Staff: Code 4, Code 4. Are you okay??]
“……What??”
[An emergency situation turns the set into chaos.]
[Code 10: I was really shocked! He suddenly just dropped right in front of us.]
The online forums watching Episode 2 in real time were flooded with talk about Code 4.
[Oh my god the orthodontia guy]
So now we’re adding the sickly keyword too?
-What are you talking about, he repeated it so much of course that happened
-I don’t care, I’m gonna keep the orthodontia friend as my sickly puppy bias
-But like how hard was he working to actually collapse ㅠㅠㅠ
-That explains it ㅠㅠ why did his face suddenly look so one-sided during the Signal song
[Fortunately, Code 4 quickly stabilized, the collapse attributed to accumulated fatigue causing temporary shock]
[Code 4: I started feeling dizzy around the tenth take or so, and when I thought it was the last one, the tension just released…… but I’m fine now!]
“What, why is he being so brave……?”
[Wait, so if that’s the case]
He sang the Signal song cam with his veins practically bulging in his neck before collapsing?
-Right;;;
-When I watched the personal cam I thought he was just struggling, but he was basically on the verge of passing out ㅠㅠㅠㅠㅠ
-Idols need to have this kind of drive
-In that state, just standing itself is amazing;;; plus he was dancing under all those lights and singing so he wouldn’t lose consciousness… that’s what that was
-Yeah I was watching the personal cam thinking like, the sound isn’t even coming through anyway so why does he need to cringe his face while singing
“Wow…”
Su-jin pictured Yu Seong-woo in the video.
The slight wavering during his dance wasn’t because his skills were lacking.
His scrunched-up face while singing along wasn’t just desperation—it was survival.
Now that she understood all of it, every frame in that video looked new.
[Honestly, I’m not impressed]
He didn’t collapse for attention or anything? The other kids are perfectly fine
-What are you saying, then why did he get hospitalized
-What do you mean fine, the other kids are all retching and losing it too lol
-Here comes the undermining already;;;
-If that’s acting he should be doing acting not idol work
Not everyone needs to feel the same way. But distorting it like this was unbearable.
“No, are they insane? How is that acting?”
Su-jin pressed her forehead with a familiar sensation.
“Oh, I’m done for.”
My bias being attacked from all sides. And this burning sense of mission to protect him.
This isn’t just becoming a fan.
Someone once said—a bias is maternal love, a second-bias is sisterly love, didn’t they?
Orthodontia @orthodontia 2 minutes ago
Make him an honorary firefighter, Code member
When he faced undermining and false criticism from all sides, it was then that he finally drew close to Su-jin and became her son.
