Ye-rin's First Jackpot and the Stock Club
Even Heerin showing interest in me felt off-putting, but Ye-rin was in a total daze right now anyway. Throughout the entire lecture, she seemed completely out of it, like she had no idea what the professor was even saying. How could she not be curious? She'd bought over 8 million won worth of stock that had nearly hit the -20% daily limit for the first time.
"Uh... okay. Hehe. That worried about it?"
"N-no... not worried, exactly... just curious. Let's hurry."
Ye-rin picked up the pace even more. She was walking so fast I could barely keep up.
"Haha... Ye-rin, slow down, you're too fast."
Thanks to her rush, we made it to the PC bang by 2:40— just ten minutes after the 2:30 lecture ended.
Ye-rin, looking like her life depended on it, fired up the computer, punched in her public certificate, and dove straight into the stock market site. She checked the current price.
-25%
44,250 won
"Gasp!"
The stock had dropped even further in the meantime.
"What do we do... it's down more... hiiing."
Ye-rin looked like she was about to burst into tears any second. I grabbed her hand—the one clutching the mouse.
"Just wait a bit. It'll go up soon."
"Really?? You think so?"
She was so fixated on the stock she hadn't even noticed me holding her hand. This was the thrill of day trading.
"For real. That's why I said there's no rush. The stock will start climbing from 3 o'clock."
"Okay. I'll trust you."
She kept hitting refresh obsessively. Sure enough, around 2:58, the chart started twitching—signs of life. As buyers piled in, it shot straight up. By 3:00, in just two minutes, it had rebounded to -5%.
Then I pulled up an article on my computer and showed it to her. It was piping hot, posted right at 3:00.
After that, related articles started flooding in like a storm.
"J-jackpot... You knew about this?"
"Mm, I dug around studying and found out the two companies were secretly in talks."
In truth, even I hadn't known. But once the articles exploded after 3:00, the price went berserk, surging wildly. By 3:20, it hit +20%.
"Sell now."
"Now? Won't it go up more tomorrow?"
"Hmm... it might climb another 10% or so tomorrow. But we've got LK Chemical tomorrow~"
"Got it."
Ye-rin didn't bat an eye at the 10% profit—she knew I wasn't fazed. She looked at me with even deeper admiration.
We sold everything at 70,800 won. My account showed 3,540,000 won, and hers had 12,390,000 won.
"Waaaaaah!! Jackpot! I not only recovered my losses but made 2 million more than when I started!!"
Ye-rin was so hyped she hugged me tight and started jumping up and down. I felt the soft press of her breasts against me. My cock twitched hard, surging with energy. But it wasn't time yet—I calmed myself down and got her to settle too.
"Ye-rin, stick with me this week, and I'll double that money—at least."
"Eeeh? For real?"
"For real. But just this week."
"Huh? Just this week?"
"Yeah. You started stocks to learn, right? If you just follow my lead blindly, you won't learn anything. Spend the week shadowing me and picking it up."
"Oh right, yeah. I got so excited I forgot the point."
Of course, I planned to keep helping her along, but it had to feel like I was the one doing her favors forever.
That way, she'll rely on me even more.
"Hyun-su, what're you up to tonight?"
"No plans. Thinking of heading home to study."
"I see... Hmm... What to do..."
She fidgeted like a puppy desperate to pee.
"What's up? Something going on?"
"No... just... wanna grab dinner together maybe?"
"Ye-rin, you know I'm broke right now... Can't keep mooching off you forever."
"What are you talking about? You made me over 4 million today! Let me at least buy you dinner."
"Alright then... Guess I'll owe you one more time? I'll take one more general elective and meet you at the main gate at 5:30."
"Sounds good."
I sat through another general elective, then headed to the gate. Ye-rin was waiting.
We hit the streets. It was just before 6:00—too early for dinner—so we wandered, window-shopping and chatting. Her hand clung to my arm as we roamed.
"Let's check that out."
She pointed to a clothing store.
"I wanna buy you an outfit."
"Clothes? No way, Ye-rin, chill. That money's not even in your account yet. The real test is holding onto profits."
"That's got nothing to do with it. I just wanna. I like guys who dress sharp... and you pull it off perfectly. My type, I guess?"
Turned out my fashion sense matched her taste.
Thanks, Heerin... heh.
She insisted so much I gave in. We bought a full outfit—top and bottom—to her liking.
"I feel bad always taking stuff..."
"It's fine, really, sir. Hehe."
Did she know how adorable she looked like that? That smile could drive anyone insane. And it was just for me—I wanted to pull her into my arms right then. But I bided my time. By next week or the one after, she'd be clinging to me for sure. She'd gotten hooked on day trading's rush, tasting massive gains all week in such a short span. Going solo after? No way she'd get that dopamine hit again.
We finished dinner and parted at the subway station. Her place was in Samseong-dong, mine in Sindorim—opposite directions. We agreed to meet tomorrow at 8:50.
No major classes tomorrow, just the club regular meeting at 10:00 and two afternoon lectures.
I figured Ye-rin might show early again, so I left extra time and arrived ten minutes ahead. She was already there.
"Ye-rin~"
"Hey, Hyun-su. You're early?"
"Why're you here so soon? Been waiting long?"
"No, no. Truth is... I was too excited to sleep... hehehe."
"Aigoo... really now?"
I playfully smacked her ass without thinking.
"Eek!"
She startled for a second but played it cool. I debated apologizing but decided against it.
"L-let's head in? Gotta buy right away today."
"Uh... yeah! Let's. Haha."
We booted the PCs, hit the stock site, and as soon as the market opened, smashed the buy buttons.
I bought 41 shares, Ye-rin 144.
"Hyun-su, why this stock?"
"I'll explain at the club meeting later."
"Okay."
She was curious but didn't push—I always explained when it mattered.
We killed time with spot-the-difference games at the PC bang, then headed to the club room. About 40 guys and girls were gathered.
"Hello, seniors. Kim Ye-rin, class of '03."
Ye-rin greeted politely right away—plenty of upperclassmen there.
"Hello. Cha Hyun-su, class of '03. Here to join the club today."
"Ooh, fresh faces? Hi, I'm Lee Soo-min, vice president. Class of '01."
A female senior greeted us. She clearly took care of herself—her body looked toned and fit just from a glance.

People fired questions at us during quick intros.
"Ooh, newbies? I'm Kim Kyung-soo, class of '99, third year. Club president."
"Yes, hello!"
I bowed to the president.
"Alright, let's talk today's topic. How'd everyone do?"
"Whoa, President, you're the best! For real!"
"Right? Amazing. I grabbed 5%."
Everyone hyped up Kyung-soo, praising him nonstop. The stock he'd recommended had risen, and his ego was sky-high.
"What'd I tell you? Straight from a Hanwha Investment senior. Hold a bit longer—it'll climb more."
"Jackpot! Really??"
Kyung-soo basked in the gratitude, then turned to Ye-rin.
"Ye-rin, you made bank too, right?"
"Huh? Oh... I..."
"What's wrong? You sold?"
"Yeah... around 10 last night."
"I told you to hold! Everyone else got over 5%!"
Fair point—5% was solid in stocks. But Ye-rin's worldview had shifted.
"Why? What stock?"
I asked her casually.
"Uh... Korean Air, the one I sold yesterday."
"Oh, that? Good sell."
I'd meant to whisper, but my voice carried—everyone heard.
