Episode 69
Kang I-yul was glad to see Yu Seong-woo.
Though his arrival was abrupt, Yu Seong-woo was like a relief pitcher for the team. Someone had come to fill the void left by Main Vocal Jeong Eun-gyu’s elimination.
“Welcome to our team, Seong-woo!”
Ji Dong-seok welcomed him loudly.
“Strange how it worked out. Guess we’re ending up as My Girl after all.”
Kang I-yul’s ears caught on Han Sang-yun’s remark.
“After all…?”
“Oh, we showed each other choreography back at the Dormitory.”
“I see.”
As Kang I-yul nodded, a sudden doubt flickered through his mind.
‘Why did he show it to Sang-yun and not me?’
It was he who had practiced with him back in the Puberty Team. It was he who had taught him the most dancing all this while.
Surely not—
‘Am I a burden to him?’
The thought struck him suddenly.
Ever since the accident, he’d been conscious of it, awkwardly apologetic, grateful too. Was he inadvertently placing pressure on him without realizing it?
After a moment’s reflection, Kang I-yul reached a decision.
‘I’ll do better.’
A debt had to be repaid properly. It was a vow to be a help to his benefactor, not a burden.
“Should we start practicing right away?”
“Yeah. Oh, Seong-woo—are you okay with Main Vocal?”
“Yes.”
“Okay. We don’t need to adjust the parts…”
Ji Dong-seok let out a breath of relief.
“Actually, I have one suggestion, hyung.”
That was when Yu Seong-woo raised his hand.
“You know that lyric—’I’ll become your boy, will you become my girl’?”
“Right.”
“The Campus Boyfriend concept is good, but what if we did it more like a Dating Simulation Game?”
“A Dating Simulation Game?”
“Each of us plays a different type of boyfriend, and she can choose one.”
It was a characteristically novel idea.
“Oh—”
“That’s amazing.”
“The concept is way clearer than just Campus Boyfriend.”
Kang I-yul nodded once more.
Working with this hyung was never a losing proposition.
“Fine. Let’s go with that for the concept then.”
Han Sang-yun clapped his hands.
“Let’s start with choreography practice. Seong-woo needs to learn it too…”
Kang I-yul raised his hand eagerly, as if he’d been waiting for this moment.
“I’ll teach him!”
“You, I-yul?”
“Yes.”
“I’d really appreciate that.”
Good. I’m going to teach him properly this time.
“Thanks so much.”
“Don’t worry, hyung. Ask me anything you need!”
“You sure about that?”
“Of course.”
But something felt strange.
‘Why is he picking this up so quickly?’
“Like this… and then like this?”
“Yes.”
“Okay~”
…That’s it?
The first movement was over in an instant. Kang I-yul could only blink in bewilderment.
“Should we move on to the next movement?”
“Ah… yes.”
He couldn’t have forced the matter anyway. It would only waste their practice time.
“Thump, tap-tap-thump-tap—”
“Like this?”
“Yes.”
“Okay.”
He finished it in one go?
“And turn here.”
“Like this?”
“Yes.”
“Ah.”
Kang I-yul grew increasingly anxious.
‘Why is he picking this up so fast?’
Before—or even just a few days ago.
He’d barely succeeded once after twenty explanations.
“Hyung.”
“Hm?”
“Do you really understand it?”
“Yeah.”
“Already?”
“Yeah.”
‘This isn’t right…?’
At this rate, they’d be done soon. No chance to repay the debt.
“Oh!”
Kang I-yul’s eyes lit up.
“This part is tricky.”
“Where?”
“Here.”
Deep down, he knew it wasn’t actually difficult. But he said it anyway.
“The arms and legs are on different beats.”
“Ah.”
“It’s easy to mix up.”
“I see.”
‘This time I can hold him here a bit longer.’
Kang I-yul immediately placed his hand on Yu Seong-woo’s shoulder.
“Thump-tap-tap.”
He moved his arm.
“Thump-tap-tap-thump.”
And matched the leg movement.
“Like this.”
Pressed close together trying to teach, their reflection in the mirror struck him as absurd.
Like a puppet on strings.
“Snort.”
Yu Seong-woo laughed first.
“We look like Pinocchio and Geppetto right now.”
Kang I-yul eventually laughed too.
The anxiety from moments before vanished as if it had never been.
“Fair point. You did make me into a person.”
The words felt strangely awkward.
“Let me try again.”
Yu Seong-woo began dancing right away.
Kang I-yul watched each movement with hawkish intensity, ready to correct even the smallest mistake.
But…
‘We’re done for.’
He dances better than before.
“What?”
“Why?”
“Um…”
Kang I-yul desperately searched for where he’d gone wrong.
The arms? No.
The feet? Not that either.
His gaze? No, that wasn’t it either.
Everything had been correct. That was the problem.
“……I’ll explain it again for you.”
But he simply forced the lie anyway.
“Oh, did I get it wrong?”
“Yes.”
“Where?”
Where indeed……
“Your arm angle, actually.”
The words tumbled out before his mind caught up, and he regretted them instantly.
“Arm angle?”
Arm angle? That’s a pretty flimsy excuse, isn’t it?
“It needs to be bent a bit more. Like this.”
“Mm……”
When he physically adjusted Kang I-yul’s posture, the other man stared intently into the mirror.
Had he been caught?
“Yeah, I see it.”
“Pardon?”
“It’s definitely different.”
Kang I-yul’s mind went blank for a moment.
……Really? He actually bought that? That pathetic lie?
“So I need to do it like this, right?”
“Yes.”
“Okay.”
“……”
“Thanks! I’ll practice it more.”
Yu Seong-woo walked over to the mirror alone.
“You should practice your part too.”
“I’ve already finished, actually.”
The words spilled out reflexively.
“Even so, try running through it by yourself.”
Kang I-yul nodded obediently.
“One more time — show me just the second verse before you go.”
“Yes……”
He watched for any sign that there was more to teach, anything that might be difficult, any hint that Yu Seong-woo wanted to explain something again.
He looked for these signals over and over.
“Thanks.”
But that was truly the end.
“Then I’ll keep practicing.”
“Yeah.”
Kang I-yul swallowed his disappointment and returned to his spot.
What he failed to see, however, was one thing.
Rounded cheeks puffed high, laughter threatening to burst free at any second.
Kang I-yul never knew.
That the person having the most fun right now was Yu Seong-woo.

Now that the Concept had been set as a Dating Simulation Game, it was time for each member to choose their character.
“You’ve got that confident Athletic Type boyfriend energy.”
I pointed at Han Sang-yun.
“Oh.”
“Like a college basketball team captain, you know?”
“Yeah, I can see it.”
Ji Dong-seok nodded readily.
“There’s something mature about it.”
“The kind of guy you’d get confessed to in front of the Gymnasium.”
Han Sang-yun looked pleased with the assessment.
“Good. Next.”
“I-yul’s the Pure Type.”
“Pure……?”
Kang I-yul’s face showed genuine bafflement.
“Your face has that quality.”
“Yeah.”
“Pure first-love material.”
“Put you in a school uniform sitting by a window, you’d win the popularity poll hands down.”
“That’s a bit…….”
Kang I-yul’s ears flushed slightly.
‘Definitely the Pure Type.’
“What about me?”
Ji Dong-seok asked with eager anticipation written across his face.
I paused to think, then answered.
“Comedy Type.”
“Hey!”
“What?”
“I’m an idol trainee too!”
“A funny boyfriend’s pretty great, though.”
“I mean, true…….”
“Funny guys are always the best.”
“That’s fair.”
He was convinced in five seconds flat. Simple as always.
“Okay. Comedy Type it is.”
“Really?”
“Yeah.”
“You come around quick.”
“Gotta acknowledge the good stuff fast.”
Naturally, attention turned back to me.
“So, what about you, Seong-woo?”
“Me?”
“Yeah.”
“Tender Type.”
“Ugh. That’s too boring.”
Ji Dong-seok immediately objected.
“But isn’t being tender basic?”
Unexpectedly, Han Sang-yun chimed in too.
“Exactly.”
“If your boyfriend isn’t tender, something’s seriously wrong.”
“But why-”
I felt genuinely aggrieved. I’d put real thought into that choice.
“Don’t you have anything else?”
“Anything else?”
“Anything fans say you look like? Some nickname or something?”
“Other than braces, I have no idea.”
Ji Dong-seok shook his head firmly.
“See, when you’re not smiling you look kind of cold? So… Cold Beautiful Boy?”
Hearing “beautiful” from guys like this, heat crept up my neck.
“Come on, I’m not beautiful.”
That was precisely why I’d emphasized “tenderness” instead of appearance.
“Seong-woo, sometimes I watch you and think you don’t even know your own face.”
Already embarrassed, and now Han Sang-yun piles on too.
“Huh?”
“Seriously, do you never look in a mirror?”
“What?”
Ji Dong-seok joined in eagerly.
“Actually, you kind of have puppy vibes? Don’t you?”
“So you want to go with Puppy Type?”
“You’re disqualified from Comedy Type, Dong-seok.”
“Whoa.”
While I stood there flustered, Han Sang-yun and Ji Dong-seok continued their analysis.
“What about the Smile Type?”
That’s when Kang I-yul, who’d been listening quietly, finally spoke up.
“Huh?”
In an instant, all eyes turned toward him.
“You laugh well, don’t you?”
A silence fell over the room.
“Him?”
Ji Dong-seok asked back, his voice trembling.
“Yu Seong-woo?”
Han Sang-yun’s expression was equally puzzled.
“Oh, no, I didn’t mean—”
Kang I-yul looked even more flustered by their reactions.
“When did he laugh?”
“Huh? He’s always laughing, isn’t he?”
This time, I was the one caught off guard.
Always?
“Every time I see you, you’re smiling.”
……
……
Ji Dong-seok seemed at a loss for words, his mouth hanging open.
Well, when we were on the same team before, I laughed once and scolded him ten times.
‘There wasn’t really a reason to laugh……was there?’
I covered my embarrassment with a cough. I don’t know—maybe it’s stranger not to smile when I’m around my favorite person.
“That works!”
I quickly changed the subject.
“I’ll go with that. The Smile Type.”
“Just like that?”
“It was the best of what you suggested.”
Ji Dong-seok gave me a sidelong glance with wide eyes and muttered playfully.
“So it’s settled—our youngest is on top, huh?”
I was relieved he’d jumped to a completely different conclusion.
And so, in the end, each of us settled on a concept: Athletic Type, Pure Type, Comedy Type, and Smile Type.
The problem came after that.
“Hyung.”
Kang I-yul appeared in front of me again.
“Do you understand this move?”
……But why do you keep trying to teach only me?
* * *
A day after the team reorganization, the Mid-term Evaluation took place.
The Practice room was quiet, but tension hung thick as air.
Kang I-yul glanced sideways.
Yu Seong-woo looked no different than usual.
‘Doesn’t he get nervous?’
It was the same yesterday.
When he said he’d practice until dawn, I tried to stay with him.
But at his words—”Managing your condition is what matters most”—I went back to the Dormitory.
I felt like I owed him something.
How does he know me so well?
“Did the reorganized team practice a lot?”
“……Yes.”
“Yes!”
“Which team should we see first?”
The order of the Mid-term Evaluation had been decided the night before by unanimous agreement.
“What, Sang-yun’s hand shot up right away? My Girl first?”
“Yes!”
As Kang I-yul stepped forward, he whispered softly.
“It’s only been a day, so it’s okay if you’re not perfect.”
It was his way of encouraging us.
But Yu Seong-woo looked as if to ask why he was even worried.
“So Yu Seong-woo’s the Main Vocal here too?”
“The Main Vocal had to drop out, so we were worried, but he’s doing really well.”
“Good.”
At Han Sang-yun’s crisp reply, the judges nodded their heads.
“Let’s see it right now, then.”
Under Kang I-yul’s direction, the four of them took their positions.
“Fighting!”
With Han Sang-yun’s resounding cheer, the intro began.
Yu Seong-woo stepped forward over a bouncy, bright 8-bit electronic synth.
[A date I marked
so carefully on the calendar]
The moment the first verse started, Kang I-yul sensed something strange.
[If I ever meet you,
I’ve prepared a cool line
to say.]
Why did it look so natural?
The expression, the gaze, the smile—everything about him seemed like he’d been part of this team from the beginning.
More than anything…
‘Why is he dancing so well?’
The last time he’d seen him yesterday, it wasn’t at this level.
‘Could he have practiced all night? Alone?’
His mind went blank for a moment.
“The concept’s fun.”
“And each character is distinct too.”
The judges were responding well.
“So Seong-woo was smiling the whole time because of the Smile Type concept?”
“Right? I’ve never seen a stage performed with that much smiling before.”
“Ah…”
Yu Seong-woo scratched his head sheepishly.
“It’s because I’ve done a lot of darker concepts up until now, I guess.”
The judges considered it thoughtfully, then all voiced their amazement.
“You know, with that cute face, I can’t believe it happened that way.”
“This stage is going to be a real image transformation for you.”
The more praise poured in, the more Kang I-yul’s confidence crumbled.
‘…Did I just get in his way?’
If he was someone who learned better practicing alone, then all that effort he’d put into teaching him had just been a burden.
“By the way, Seong-woo,”
Katin asked, smiling.
“How did you pull this off in just one day?”
“I mean—I’d believe it if you said you were part of this team from the start.”
It was the question Kang I-yul had wanted to ask. He genuinely wanted to know how he’d done it.
“I-yul kept teaching me the whole day!”
“…?”
For a moment, Kang I-yul couldn’t believe his ears.
“Thanks to him, I picked it up really fast.”
“Oh? I-yul again?”
“Didn’t the same thing happen during the Signal Song? You two work really well together—”
The more praise flowed, the more Kang I-yul wanted to cry.
He’d meant to help, but somehow he’d ended up being the one helped instead.
‘This guy really…’
He didn’t even give him a chance to settle his debt.
