Bet with Professor Lee Eun-joo
I knew Lee Eun-joo would come straight home after I texted her. I could tell she was curious about me, and she'd show up anywhere to satisfy that curiosity.
Time was short, so I hurried to tidy up. My place wasn't usually messy, but with a woman coming over, some extra effort was needed.
Soon, it was 2 PM. Peeking out the window, I saw a luxury foreign car pull up in front. Then Professor Lee Eun-joo stepped out.
I headed out to greet her.
"Professor. Over here~"
The villa I lived in was three stories with no elevator—just stairs.
Eun-joo stepped inside.

"Oh. Pretty tidy. Doesn't look like a guy's bachelor pad."
"Well... I put in extra effort since you were coming."
"As expected... slick move. You ditched the 'always tidy' image and cleaned just for me, huh?"
"Mm... both? Hehe."
"Ha? How are you so smooth at 20?"
"Age doesn't determine maturity."
"And you talk so well. Real smooth, huh?"
"Kukuku. You think?"
"Ahahat. Yeah. Anyway, show me what you wanted to show."
"Right! This way?"
I guided her to the computer and turned it on. Her eyes sharpened at the neat desktop, sizing up my personality.
I pulled up my week's stock trades.
"Heavens!! No way? This real?"
"Yes. As you see."
"Day one: Hanyang Trading. Day two: Daewon Motors. LK Chemicals. Sehan Bank. Sold and Hanseong Electronics? Total trades now... 12.4 million won?????"
I'd bought Hanseong Electronics at -6% on Thursday; it hit +20% that day and +25% by Friday close.
"Started Monday with 1.5 million... nearly tenfold in five days?"
"Just a bit of study gets you there."
"Study does this?"
I explained why I'd picked those stocks. Explaining rises after the fact wasn't hard.
Eun-joo was stunned, realizing my skill. But she thought my method was flawed—too risky, one slip and you're done.
"Hyun-su, impressive, but don't do it this way. One mistake and you lose everything."
"I trust my skills. It's 12 million now, but it'll grow fast."
"No. As your stocks professor, this is wrong. Looks good now, but it's tightrope over a cliff."
"Professor. I won't fall."
"Really! You won't listen. Who falls on purpose? That's not confidence—it's arrogance! Hubris!"
She was furious. She acknowledged my talent but saw it leading to ruin. Many had seemed successful like this, only to crash miserably.
"Professor. Wanna bet?"
"What bet?"
"I'll turn 10 million into 100 million in one day."
"Tenfold in a day? With stocks?"
"Yeah. Believe me then?"
"Impossible. Stocks have daily limits. 1,000% profit? Never."
"Bet then. Honor on the line—loser obeys winner."
"Fine. If I win, I'll fix your aggressive style."
"Good. Next Friday, 9 AM, right here. No class for me."
"Deal!"
Driving home, Eun-joo thought, What's with this guy? Tenfold in a day? 1,000% returns? What confidence. If I win, I'll straighten him out.
I was confident I'd win the bet. I'd avoided intraday trades before—too much to memorize for full days. But skipping Monday-Thursday and all-in on Friday? Doable.
Ye-rin needed weekend rest, so I texted Soo-min to meet.
Saturday, she came right out, no hesitation.
"Sehan Bank!! Hyun-su, you're a legend. Did exactly as you said—capital nearly doubled. LK Chemicals to Sehan, all hit limits."
"Hehe. Senior, you trust me?"
"Of course. Who else but our chairman?"
"Kekeke. Tell our VP to serve the chairman well."
"Yes sir. Loyalty! Loyalty!"
She saluted playfully, pledging allegiance.
"Loyalty in bed too?"
"Yes sir. Total submission in bed for the chairman!"
"Kahaha. Makes me wanna do you now. Let's go."
I got the royal treatment from Soo-min. Ye-rin needed more teaching; Soo-min was nearly perfect—just tweak to my tastes.
"Haang... haang... good?"
Soo-min rode me hard, facing away. Her firm ass bounced resiliently.
I couldn't resist—smack!
Handprint bloomed on her elastic cheek.
"Ack! Wha—what?!"
Pain made her turn mid-ride.
"Eyes front. Keep moving."
Smack! I commanded, slapping again.
"Aack! Got it..."
"Yes. Absolute obedience to chairman's orders. Understand?"
"Yes. Loyalty!"
Soo-min was mine completely. Controlling this toned body thrilled me. Her skills were top-tier too—best in bed.
Splurt!!
I came hard from her relentless pounding.
"Chairman. Let me clean you."
She eagerly sucked her juices and my cum off me.
Her mindset was perfect.
"Why does our chairman's cock taste better every time?"
"Good. Daily tips for our VP, not weekly."
"Aaaah! Yes~!"
If there was a status window, her loyalty would be skyrocketing.
Saturday with Soo-min, Sunday resting at home.
Monday: time loop week.
Loop weeks meant indulgence—order craved foods, binge games, max stress relief. Avoided people, solo time.
Active weeks: healthy eating, workouts. Loops: meaningless. Prioritize joy—body resets anyway.
Even if I gained weight, it vanished on reset. Enjoy loops, endure active weeks.
Usually skipped school to avoid connections. But Thursday: mandatory for "Probability and Statistics."
Class ended; Kim Ga-young called me out, smug. Wrote a problem on the board.
Looked back: Think you can solve this, punk?
Of course not. Math wasn't my strength.
I couldn't solve; she gloated, personal attacks flying.
I half-ignored, memorizing the board.
Noticing, she stormed over, jabbing a finger.
"Ah. Move. Can't see the problem."
I shoved her head aside.
She stumbled, skirt flipping—panties exposed.
"Kyaaak!"
Laughter erupted. Haughty professor's mishap was hilarious.
"Hey!! You...?"
Problem memorized, I turned.
"Dare push me?"
Glare met low kick to thigh. As she fell, middle finger up—I bolted.
Seeing her writhe felt great.
Next, Korea University math TA.
"TA, can you solve this?"
Shoved the problem at him.
"What? Who're you?"
Grumpy glare. I pulled a 1-million-won envelope.
"Gasp!"
"Solve it, it's yours."
1 mil per problem? No-brainer.
"Hmm... tricky, but doable for math folks."
Solved, took cash. Verified with high school and another uni TAs—another 2 mil. Answers matched.
Friday: stock sites from 9 AM, eyes glued to charts.
1,000% in a day? Tough, not impossible. Find minute-by-minute volatility spikes.
Found viable paths. Jotted on A4: one page.
Now, memorize. Plus one buy/sell per day Mon-Thu—easy.
