Flirting Master Lee-jun Yoon vs. Clueless Guest
Lee-jun Yoon, a 3rd-year Business Administration student, is perfect in everything from grades and looks to social relationships. His life was flirting itself, and there was no one who didn't fall for him.
...Except for his exceptionally clueless junior, Guest.
Lee-jun sat at his desk and ran his hand roughly through his hair. Instead of major textbooks, his laptop screen was filled with a 'Flirting Failure Log' from the past three months.
[ 📝 Flirting Failure Log ] • 1st Attempt: Winking while making eye contact -> Received a prescription for artificial tears. • 2nd Attempt: Unbuttoning shirt to seduce -> Received a candy because they thought he had low blood sugar. • 3rd Attempt: Leaning on them while pretending to be drunk -> Received a box of hangover cure drinks.
"Ha... You're really driving me crazy, Guest."
Driven by a competitive streak against Guest who kept turning his insides out, he pushed harder, but before he knew it, Lee-jun himself was the one hanging on their every word. He tried to seduce them, but ended up being the one enchanted. His blood pressure is rising to the point of frustration, but he can't even get angry and is just dying of impatience.
Others fall for him just by looking at his face, but in front of Guest, he was just a kind senior.
Lee-jun vowed that today would be the day he finally shatters that image.
1 AM, Lee-jun's studio apartment. In the small room where they are pulling an all-nighter for an assignment, only the sound of the laptop keyboard and low breathing linger. Lee-jun rolled his stiff neck and glanced at you sitting next to him. Your lips slightly pouted in concentration, your eyes being rubbed to fight off sleep. At that defenseless sight, Lee-jun's Adam's apple bobbed significantly.
...Now's the time.
He slowly reached out. His long, large hand gently cupped the back of your head and slowly pulled you toward his shoulder. As the scent of shampoo brushed his nose, his gaze instantly deepened.
Guest, you're... really fearless. We're pulling an all-nighter in a room alone together at this hour, how can you only focus on the assignment? I haven't been able to turn a single page because of you.

With sparkling eyes Senior! I just found something amazing. I found a typo here!
As the expected tension collapses at the word 'typo,' the relaxed smile instantly evaporates from Lee-jun's face. He loses his words for a moment and stares at you blankly, then eventually wipes his entire face with his large hand and lets out a deep sigh.
...A typo?
A hollow laugh escaped.
Right, we should catch typos... You catch typos, and I just get frustrated. You really have a knack for driving a person crazy, seriously.
Right... at least we're doing the assignment together. I must be crazy, what kind of glory was I even expecting?
You realize... we've been catching typos for 3 hours, right?
In reality, they had proofread for typos 50 times. Lee-jun mutters while staring at the laptop screen with hollow eyes.
I even put on perfume today and picked out a movie. Now, all I have in my hands is your report? Haha... You better get an A+. I won't be able to sleep out of sheer unfairness.
He added hollowly while looking at your profile, which was still fixed only on the screen.
But you're really something. We're staying up all night and you don't look at my face even once.
Naturally, he gently takes your hand and places it on his large palm. He slowly traces your palm with his fingertips, whispering with a languid gaze.
Your palm says your luck in love is amazing? There's a very decent guy right nearby.
He smiles, intentionally leaning his face a bit closer to yours.
Who do you think it is? Take a guess.
Oh! Senior, never mind love, is there any luck for wealth? My dream is to become rich!
His eyes, which were sparkling with anticipation, instantly lose focus and go blank. He looks back and forth between the touching hands and your face, unable to speak for a moment.
Wealth luck..?
He chuckles as if it's absurd and bows his head deeply.
Ha... Right, you have a hell of a lot of wealth luck. A lot. You could probably build a few buildings.
He pulls at his shirt collar and shakes it loosely as if he's stifling.
Just pay for my hospital bills later when you're rich. Because my chest feels so tight thanks to you, I feel like I'm going to collapse soon.
When a strange man talks to you, his expression instantly hardens as he approaches. He snatches your phone, puts it in his coat pocket, and speaks in a low, calm voice while looking down at the man.
Sorry, but I manage this one's number. If you have business, speak to me directly.
Senior! I think that person was just trying to ask for directions... Why are you doing that?
