My Sister's Friends Drive Me Crazy
I saw Yang Mina off and returned home, collapsing onto the bed.
I was watching a video on my phone when a message from Yun Seona popped up.
Meeting in the evening meant we could drink, set the mood, and head to a motel or my studio apartment together.
Just thinking about the body I saw on Yun Seona that day made my lower half twitch with arousal again.
She really loves those rabbit emojis.
“Hmm, what should we eat…”
Sushi was safe, but I’d already gone with Yang Mina before.
…And the best place around here was exactly that one.
Should I just go there?
I browsed a few options before deciding to stick with sushi. It was a reliable spot, and I wanted Seona to try it too.
I took a short nap to be in top condition, then showered and picked out my clothes.
I arrived at the subway station and waited a bit until Yun Seona came up the stairs.
“Did you wait long?”
She wore a white ball cap, a white short-sleeve button-up shirt with the middle button fastened, and a hint of her pale midriff peeked through. Underneath was a white crop top, paired with beige pants and a brown leather belt.
She carried a white bag, but what really stood out was the white choker around her neck.
A simple outfit suddenly turned sexy with just that one accessory.
I was so distracted by her fashion that I answered a beat late.
“…No, I just got here.”
“Good.”
“Shall we go?”
When I held out my hand, Yun Seona smiled brightly and took it. Her hand was warm, soft, and delicate.
As we walked together, I felt countless eyes on us. Men and women alike turned to stare at Seona as they passed.
That’s how striking her appearance was.
Tall with perfect proportions and long, elegant limbs.
She was impossible not to notice.
Looking at her felt like it improved my eyesight.
“Hm? Why are you looking at me like that?”
“Nothing. You just look really pretty today, noona.”
“Aww, what’s that~.”
Yang Mina would’ve punched me here.
Instead, Seona just covered her mouth and giggled, which felt refreshingly new.
We arrived at the sushi place together. After waiting about thirty minutes, we got a table and ordered. Something we didn’t order arrived.
“Um, we didn’t order this?”
“It’s on the house.”
“Oh… thank you.”
I’d been here dozens of times and never once gotten free food. Suddenly they’re giving out complimentary dishes? Fuck.
Seona, completely unaware, was busy taking photos of the food.
“So anyway~ Mina confirmed it was definitely men’s clothing. She said it was last year’s limited edition or something, and she demanded to know who the boyfriend was. It was total chaos. Hehe.”
“Uh-huh.”
It was the story about Seo Hyeonji’s boyfriend scandal.
Hearing about Seo Hyeonji from Seona right after Yang Mina made my heart pound like crazy.
“What about you, noona? Do you have a boyfriend?”
“Me? Nope… I don’t, that’s why I came out to eat with you today~.”
“I can tell.”
“What?”
Seona pouted her lips into a little ‘ㅅ’ shape and glared at me. Cute.
“I’m kidding. By the way, noona, are you close with Kim Yuyeong?”
“Yeah. We’re besties.”
“How did you end up getting close with a girl like… her?”
“Why? Yuyeong’s really nice.”
Just how many layers of masks does that gorilla wear that all her friends think she’s kind?
Is it hidden camera footage or something?
“We sat next to each other in first year of middle school. I don’t even remember exactly how we became friends… It just happened naturally? We just clicked.”
“You clicked…? With that gorilla?”
“Pfft, gorilla? Yuyeong is so gentle and kind. She even does volunteer work.”
“Volunteer… what? I think I heard that wrong.”
“Want to see pictures? I went with her once before.”
Seona scrolled through her phone and showed me some photos. Among them was one of her in a swimsuit. A white bikini, mirror selfie.

“Ah!”
“!!”
“Did… did you see…?”
“You showed it to me, so yeah.”
“I didn’t mean to show you that…”
“Then who were you trying to show it to?”
“I-I wasn’t trying to show anyone… I just took it for fun.”
“I didn’t get a good look. Let me see it again.”
“So embarrassing~.”
“Whoa, noona, you’re completely red. Hehe.”
Her face, ears, neck, and collarbones had all turned bright red.
It hadn’t looked this intense in the dark before, but under bright lights, the contrast was obvious.
The white outfit made it stand out even more.
Flap, flap.
Seona fanned her face with her hands to cool down. When I joined in and fanned her too, she burst out laughing.
“Did you just come from the sauna? Goodness, how long were you in there?”
“What are you even saying… hehe.”
After we finished eating, we looked for a café. Seona pointed at one and said,
“That café looks cute. How about that one?”
The place she pointed to was the second-floor café I’d gone to with Seo Hyeonji.
Oh shit.
‘No way. If we go there, I’m one hundred percent getting caught.’
I used every ounce of quick thinking I had to shoot it down.
“Uh, that place isn’t great. The coffee and the interior both suck.”
“Really? Then… what about that one?”
“Oh, that one looks good. Want to go there?”
“Yeah.”
Phew.
We entered the café Seona chose and sat across from each other. Her shirt had slipped to one side, revealing her smooth left shoulder.
“Noona, did you do that on purpose?”
“Hm? Do what?”
“Your shoulder.”
I poked her left shoulder a couple times. Seona looked down at her own shoulder and quickly adjusted her shirt.
“I-I didn’t do it on purpose…”
“I thought you were trying to seduce me.”
“Uhuu~ What are you saying?”
The way she covered her mouth while laughing was incredibly feminine.
After dealing with girls who didn’t act like girls, perverted guys who acted like girls, and perverted girls who acted like little sisters, seeing genuinely feminine Yun Seona made me think, *This* is what a noona should be like.
We chatted about random things that happened at school, then moved on to high school stories, and before we knew it, time had flown by.
It was already ten o’clock.
“Noona, are you busy tomorrow?”
“Hm? No?”
“Then you can stay with me a little longer, right?”
“Hm? …Yeah.”
“There’s a nice bar nearby. Want to go drink?”
“…Sure?”
Seona didn’t hesitate. She shyly nodded. She must have been hoping for this.
So she really did come out today planning to do it with me.
My dick was already throbbing. This was dangerous.
I took Seona to a room-style bar.
This place was a famous spot in Star University’s college town.
There was a long-standing saying passed down through generations: if you want to seduce a girl, bring her here.
The seniors had told our freshman class about it during OT when all the guys were gathered together.
Since it was Saturday, every room was packed. Luckily, after waiting about ten minutes, it was our turn.
The guys waiting in line with us stared at me with pure envy in their eyes.
That’s right, you bastards.
“Wow, I’ve never been to a place like this before.”
“Really?”
“Yeah. It’s so cool. The door even closes? Whoa~.”
She played with the sliding door, adjusted the brightness of the wall lights, and fiddled with the air conditioner, clearly fascinated by the private room.
“Didn’t you go to a lot of bars with the gorilla?”
“We do like drinking, but we usually just drank at someone’s studio apartment. We didn’t go to bars that often. Everyone lives far away, so it’s hard to stay out late.
To really enjoy ourselves we’d have to pull an all-nighter, but Yuyeong’s drinking habit is falling asleep immediately… so having a room was better.”
“I see. That so?”
So that was the gorilla’s drinking habit?
Next time I get the chance, I’ll just get her wasted and knock her out. Then I can step on her a few times while she’s sleeping.
Good information.
The drinks came out first. I clinked glasses with Seona.
She really could drink. The food hadn’t even arrived yet and she’d already finished a bottle of soju and a 500cc glass of beer.
At this pace, I wouldn’t last even an hour.
Thankfully, the food came out before we ordered the next round.
“Mmm, this is delicious.”
Seona looked delighted as she tried the mille-feuille nabe and tofu kimchi that came as sides.
“I’m glad.”
“This place must be really famous. There are so many people.”
“It’s probably the most famous bar at our university.”
“Really? That explains it… Are they all Star University students?”
“Pretty much.”
“Hehe, then maybe one of your friends is here?”
“What? Maybe?”
We clinked glasses again…
“Yuon, I need to use the bathroom…”
“Let’s go together.”
I finished first and waited outside for Seona.
“Hey, Kim Yuon?”
A woman’s voice called my name.
“…Park Jiyeon.”
When I turned around, Park Jiyeon was there with two other girls.
She staggered toward me. Her eyes were glazed over—she was already pretty drunk.
“…Who are you here with? Yun Suhyeon?”
“Someone you don’t know. Someone who’s none of your business. Someone you don’t need to know.”
“Ha! Is it a girl?”
“Why do you care?”
“…Hmph.”
When I answered curtly, she stuck her lips out and glared at me.
I used to think that was cute. Now that the rose-tinted glasses were off, it just annoyed me.
What the hell did I do so wrong? If you got horny, of course I’d get hard too.
I wanted to argue while the alcohol was still in me, but Seona came out just then.
“Yuon, were you waiting for me?”
“Yeah.”
She looked back and forth between me and the three girls, then asked quietly.
Park Jiyeon also stared between me and Seona, eyes wide.
“Who’s that, a friend?”
“…Just a classmate from university.”
“Oh, hello.”
“Why are you even saying hello? Let’s go.”
I grabbed Seona’s wrist and pulled her back to our room. Park Jiyeon’s expression was so ridiculous that I couldn’t help but snort.
“Why are you laughing?”
“Ah… that girl just now… she’s my ex-girlfriend.”
“That pretty girl? You’ve got game, Yuon.”
“Pfft. Game? Hardly.”
“No wonder~ I thought you seemed like a player~. How did you seduce her?”
“Just… we met at OT, got drunk, and hit it off… something like that…”
Seona gave me a sly smile.
“Did you do it that day?”
“No… just kissing. Didn’t I tell you before? You were my first, noona.”
“……!!”
Seona’s face flushed instantly.
It went all the way down to her collarbones. She complained about being hot and took off her shirt, revealing her smooth, reddened shoulders.
“Was I your first too, noona?”
I already knew from Yang Mina that I had been her first, but I pretended not to know and asked anyway.
I wanted to hear those cherry-like, luscious lips admit it herself.
Seona turned her gaze away and fidgeted.
“I-I don’t knooow…”
“Did you have a boyfriend before?”
“Aish, really… I didn’t…”
“Then I was your first too, right?”
“……”
She turned her head away and kept fanning herself furiously.
“Yun Seona, you have to answer me.”
“………Yeah.”
Seona answered shyly, her face burning red. So cute.
I casually moved over and sat right next to her.
Seona made room and scooted further inside.
Thump— Thump— Thump— Thump—
My heartbeat was louder than the heavy bass of the music. We were so close it felt like the other could hear it.
I was feeling a thrill I’d never experienced before.
I wondered if Seona felt the same.
Her eyes trembled faintly when they met mine. Her breathing grew rough. Her lips parted slightly.
When I touched her cheek, it was burning hot.
As Seona quietly closed her eyes—
I pressed my lips against hers.
