What Are You Doing to Unnie?
"What are you doing to unnie?" *Bang.*
I jumped in shock at the sudden voice and whipped around, but no one was there. The door, which must have opened at some point, was just quietly swinging shut.
Crazy...!
"Ahh, ahhh..."
I yanked my dick out from where I'd been pounding away furiously, and our mixed juices splattered lightly, staining Shin Soye's navel. It was a sight that could steal anyone's attention, but right now, I had something more urgent to deal with.
"Sejin...?"
"Just a sec."
I gave a quick reply to Shin Soye, who called out to me in a voice laced with surprise and disappointment, then hastily pulled up my pants and bolted out the door.
No one was in the hallway, but as I scanned around quickly, I caught a glimpse of heels disappearing at the far end of the corridor.
That person. That's the one who saw us in the waiting room and ran.
I chased after them fast, but at the end of the hall, there was only the elevator doors closing as it descended.
"What's wrong, Sejin?"
Shin Soye finally caught up, having thrown on her clothes. Her hair was a bit messy from how wildly I'd been fucking her moments ago, and a bead of sweat trickled down between her disheveled cleavage. Even in a situation like this, her body was sexy enough to draw the eye.
I desperately tried to pull myself together and asked her, "Didn't you hear that?"
"Hear what?"
"Someone must've been peeping on us in the waiting room. Looks like they just took the elevator and bolted..."
"I didn't hear anything."
"The door was open too."
It'd be great if I'd just misheard, but with the door ajar like that, I couldn't count on it.
"Even from the door, they probably couldn't see us clearly... We're probably fine, right?"
"No way. If this gets out, we're screwed."
"Even if they find out we're together like that, I don't care..."
"It'd be a huge risk to your idol career, noona. You've got so much more ahead of you—your momentum can't get stalled now."
Shin Soye fell quiet at my words. Maybe she'd raised her voice in surprise, but her expression looked oddly pleased, like I hadn't hurt her feelings. I was curious what she was thinking, but right now, getting out of here came first.
I don't know who it was, so let's just bail for now. If any rumors pop up later, I can play dumb.
My heart was pounding, cold sweat trickling down. If only I knew who it was—but it was too late for that. Best to establish an alibi quick. Like noona said, we were in a spot not visible from the door, so if we hop in the van and act like we were never here, it'll be easier to deny later.
"Noona, let's head back to the van."
I grabbed Shin Soye and hopped into the elevator right next to us. As we got in, I saw the other elevator's indicator stop at the underground parking lot.
On the way back to the van, I carefully checked the parking lot for anyone around. But the underground lot, restricted to staff only, was empty—not a soul or even many cars.
Guess I lost them...
I sighed inwardly as I helped Shin Soye into the van, then slid into the driver's seat and reflexively apologized.
"Sorry, Haeun-ssi. Got held up talking to the PD in the lobby."
"Hurry up."
Im Haeun, nagging like always.
"Sorry, Haeun-ah, I didn't think we'd get caught~"
"...Got it, unnie."
But there was something off about her voice—drained, somehow. Her reaction felt weird too.
"...Haeun-ssi?"
I turned to look back, and Im Haeun was staring at me quietly.
"Something wrong?"
"...No, nothing."
She gave a vague answer and whipped her head away. But something was definitely strange. As I instinctively scanned her from head to toe, I froze.
Those shoes...
I'd only glimpsed the heels, but I knew instinctively—they matched the ones I'd barely seen in the hallway.
Was it Im Haeun?
The timing fit for her to drop by the waiting room, the elevator heading to the parking lot, and the empty lot with no footsteps... The circumstantial evidence stacked up.
It adds up.
I stared at Im Haeun for a moment. She either didn't notice or pretended not to, just gazing out the window in silence. Normally, she'd be nagging me to get going. After watching her a bit, I turned back and quietly started the car.
Those shoes... they were Lee Sejin's.
Im Haeun was thinking the exact same thing as Lee Sejin. She'd bolted before getting a clear look, thanks to knocking over a trash can, but she'd seen the shoes too. The loafers on the guy shaking his hips furiously—they matched the ones Lee Sejin was wearing.
But...
She had suspicions, but no proof. She couldn't be 100% sure it was Lee Sejin and Shin Soye. All that was left was to confirm it.
From that day on, Im Haeun started observing Shin Soye and Lee Sejin closely—from him driving the car and running errands to giving advice on lessons and work...
Before, she'd dismissed him as just an errand boy, but now every move he made bugged her.
Lee Sejin... what are you doing to unnie?
Thanks to her arrogance and prejudice, Im Haeun never dreamed they could actually like each other. She just suspected Lee Sejin was blackmailing Shin Soye or something shady.
So, Im Haeun decided to probe Shin Soye first.
"Unnie, anything going on lately?"
"H-Huh? N-No, nothing. Nope."
That evening at the dorm, Shin Soye fumbled oddly at Im Haeun's casual question.
"Really?"
"Wh-Why do you ask?"
"Just... you seem different lately. How should I put it?"
"Soye unnie... you've been all smiley and bubbly lately..."
"Oh? That obvious, Minji-ya?"
"Yeah. You seem happy all the time... unlike before, when you looked tired a lot..."
"W-Well, we're finally hitting it big, right? Gives me energy~"
"That's not quite it... it's like, weirdly..."
"Enough."
Like she was trying to shut Park Minji up, Shin Soye suddenly grabbed her breasts.
"Eek, unnie, not again..."
"They feel bigger? You said you hit 100cm last time? Feels even bigger now."
"I-I don't knooow... Hiiing, stop touching..."
"Whoa~ Gotta be around 105cm now?"
"It tickles... Haeun unnie... save meee..."
"Alright, alright, stop bullying her, unnie. That's sexual harassment."
Im Haeun reined in Shin Soye appropriately and thought,
Yeah, like Minji said—unnie actually looks more energetic lately.
She looked like someone with good things going on, not blackmailed or in trouble.
Realizing that anew left Im Haeun confused.
So unnie's not being threatened...
Shin Soye, kind and bad at hiding her feelings, couldn't mask her mood perfectly. If she were being blackmailed, she wouldn't be this chipper.
Plus, watching Shin Soye and Lee Sejin together, they seemed even closer than before—subtly looking out for each other...
Im Haeun's confusion deepened.
Time to probe Lee Sejin instead.
When the results didn't match what she wanted, human instinct was to hunt for another reason. Ignoring the possibility they actually got along, she concluded she needed to watch Lee Sejin.
So for a few days, Im Haeun observed him—and discovered something unexpected.
...This guy's got a better body than I thought?
Pecs peeking through his t-shirt, solid-looking arms. When we first met, he didn't have this healthy vibe at all...
Come to think of it, he'd said he started working out to encourage Shin Soye.
What? Working out together? Weird dude.
Managers usually just nag—they don't join in. But actually sharing the pain and motivating? Odd guy.
She'd thought that back then and moved on, but he'd clearly stuck with it. Lee Sejin, maybe not as bad as I thought...
Wait, did something happen with unnie around then?
Thinking back, his workout start lined up with when unnie started acting off.
So maybe he'd pulled something during those sessions.
Alright, I'll work out with Lee Sejin too.
Do the same thing and see if he tries anything on me. That'll reveal what he's up to.
"...Hey."
One morning during training time. Im Haeun spoke to Lee Sejin, who'd brought her to the gym.
"You said you started working out to encourage Soye unnie, right?"
"Yeah. Soye-ssi gets motivated with someone alongside, so I figured it'd help."
"...Just Soye unnie? Ignoring the other members?"
"No, not like that. But Soye-ssi seemed to hate exercising so much..."
"Minji hates it more."
"Instead, I make her special lunchboxes. For Minji-ssi, tasty meals motivate her more than joint workouts."
And true to his word, the bentos he'd been packing lately had definitely boosted Park Minji's drive. Everything he said made sense.
"...And me?"
But to Im Haeun, it felt weirdly discriminatory. She hadn't cared before, but saying it out loud stirred that feeling.
"Haeun-ssi, you're already great at working out. Your figure's perfect—no need for me to butt in."
"Hmph, obviously."
Ah, right. He was just rating me highly. Im Haeun reflexively replied to his praise, satisfied.
No, wait. That's not the point.
She caught herself. The goal was to keep him close and figure out what kind of guy he is. Why get happy over obvious flattery?
"...St-Still, I'd work out even better with a spotter, right?"
"Then I'll find you a good trainer. Since you're perfect at body management and workouts, Haeun-ssi, we need someone really skilled..."
"Yeah... No, wait! You do it."
"Me?"
"Yeah. Don't treat me different."
"It's not discrimination..."
"You arguing?"
"No, got it. We'll start today."
Alright, time to watch what this guy's up to.
I'll figure out what he did to Soye unnie first.
Even as a strange feeling nagged at her, Im Haeun steeled her resolve.
