Grab the Regressor by the Collar and Debut! Chapter 100
Chapter 100 – Beautifully, Beautiful Once
“Ah… it’s not coming together.”
The squeak of sneakers against the practice room floor stopped.
Alone in the empty room, Kim Won-ho pulled off his headset, letting it fall around his neck. His fingers dragged through his damp hair, rough with frustration.
“I feel like this part needs a stronger point….”
Sweat stung his eyes, but he didn’t sit.
He couldn’t.
The Silence
When his movements stopped, silence rushed in.
And with it—
something darker.
Can I really do this?
Won-ho had started to feel it more and more these days.
Fear.
Not of others—
but of himself.
He stared at his reflection.
The version of himself in the mirror looked… frozen.
Kim Won-ho.
Not as physically striking as Lee Do-ha
Not as visually perfect as Jung Si-woo
Not as naturally gifted as Lee Yu-geon
Not as confident as Kang Ha-jin
Not even with a tone as pretty as Joo Eun-chan
Just—
himself.
Can I really stand next to them?
That was the real question.
The one he couldn’t say out loud.
Because now—
he wasn’t just following anymore.
He was leading something.
“Because you looked like you could do it.”
Ha-jin’s words echoed.
“I don’t bet on things that won’t work.”
“….”
Won-ho clenched his jaw.
“I don’t have time for this.”
Interruption
“Huh? You were here?”
“…Ah. Yeah.”
Lee Yu-geon walked in casually, like nothing mattered.
Notebook in hand. Hoodie loose. Expression easy.
“You practicing rap?”
“Yeah. Can I stay here?”
He dropped into a corner like he owned the place.
“I escaped. If I go back, Do-ha hyung will catch me again.”
“…Why?”
“He’s scary. Keeps correcting everything.”
Won-ho blinked.
Then said quietly—
“That means he thinks you’re worth teaching.”
“…Huh?”
“He doesn’t waste time on people who can’t do it.”
Yu-geon paused.
Then flopped backward again.
“…Whatever. What were you doing?”
“Choreography.”
“Show me.”
Movement Again
Won-ho hesitated—
then nodded.
Music played.
Squeak. Squeak.
His body moved again.
Stronger this time.
Because—
someone was watching.
“…How is it?”
Yu-geon stood up instantly.
No hesitation.
“It’s good.”
“…Really?”
“Yeah. Makes me want to learn it.”
Won-ho froze slightly.
“But—”
Yu-geon stepped in beside him.
Already copying the moves.
Perfectly.
“Change this part.”
“…Huh?”
“Too hard. Si-woo hyung and Do-ha hyung won’t keep up with that step.”
He adjusted it.
Cleaner.
Better.
“And here—make it more restrained.”
“…Ah… yeah, I thought that too.”
“Then change formation.”
Everything Yu-geon said—
just flowed.
No overthinking.
No hesitation.
No fear.
And that’s when Won-ho realized—
Jealousy is pointless.
This was just—
who Yu-geon was.
The Gap
“This is fun.”
Yu-geon grinned.
“Dancing’s way more fun.”
“…You really don’t want to debut?”
“No.”
Simple.
Clean.
Certain.
“If you debut, I’ll buy your album.”
“…Do you think I can?”
Yu-geon didn’t even hesitate.
“Yeah.”
“You dance well.”
“You sing better than me.”
“You make choreography.”
“You’re easy to work with.”
He smiled wider.
“My sibling likes you too.”
No calculation.
No doubt.
Just—
truth.
And somehow—
that made Won-ho feel lighter.
“…Do you want to help me?”
“Hm?”
“Choreography.”
Yu-geon stretched lazily.
Then stood.
“Sure. Sounds fun.”
Quiet Hope
Won-ho smiled.
Maybe…
I can shine too.
Even just once.
