The Transfer Student's Introduction
"Today we have a new transfer student joining our department, Yoon Seung-woo. Please give him a warm welcome with your applause."
Clap, clap, clap—
As the professor finished his introduction, the students in the lecture hall began applauding me where I stood at the front.
I tried my best to hide my dazed expression as I took in the scene.
After rushing to change clothes and arriving drenched in sweat, I had somehow become a student at a university I knew nothing about.
All of this had happened in just a few short hours.
Especially for someone like me who had only graduated high school, the sight before me felt even more alien.
Everyone was looking at me.
Once the applause died down, an unspoken moment arrived for a brief self-introduction, and tension crept up my spine.
'Get it together.'
I steadied my breathing internally and forced a bright expression onto my face.
"My name is Yoon Seung-woo! I'm twenty-two years old and graduated from Hangyeong High School. Since I transferred in the middle of the semester, there's a lot I don't know, so I'd really appreciate it if everyone could help me out. Of course, I won't ask for help without giving anything in return. I'll do my best to repay you with my academic knowledge!"
By the end, I had regained some composure and added a light joke with a smile.
Glancing around the room, I noticed a few students chuckling in amusement.
As expected, Lee Ji-ah was among them, with her best friend Kim Ha-rin sitting right beside her.
Both of them were staring at me with particularly bright eyes.
It was only natural.
The high school I had casually mentioned in my introduction was the very one they had graduated from.
Since I had claimed to be only a year older than them, I was now nominally their senior.
Anyone would naturally feel curious upon hearing that their high school had a senior among them.
'The perfume I sprayed before coming here probably helped too.'
Despite being a sudden mid-semester transfer student, no one in the lecture hall questioned my presence.
It was partly thanks to the professor's introduction, but also because of the perfume I had applied before arriving.
One of the items provided by the company, the perfume had the effect of lowering people's guard and increasing their sense of familiarity toward me.
[Remember, it only reduces their wariness. It doesn't make them like you.]
The voice in my head—Guide, who had returned to my body—cautioned me, worried I might make a mistake.
'Got it.'
[Aha— Then enjoy your fun university life.]
'This is work, you know.'
[Might as well enjoy it on the side. You were always curious about what university life would be like back in high school, weren't you?]
Once again, Guide spoke to me in a familiar tone based on my memories, leaving me with a complicated feeling.
"There's an empty seat next to Ji-ah. Why don't you sit there?"
Following the professor's words, I took my seat.
To my right sat Lee Ji-ah—the company's target, the one I ultimately needed to brainwash.
Before sitting down, I gave her a slight nod as if to say "please take care of me," and she responded with a gentle smile and a light nod of her own.
Incidentally, the professor telling me to sit next to Ji-ah was no coincidence.
It was something I had requested via text message beforehand.
'She's prettier in person. She must've gotten a lot of confessions from guys back in high school. Or maybe even now.'
Seeing Ji-ah up close, her appearance was far more striking than in the photos.
The first impression that struck me was her purity and innocence.
In reality, despite having a boyfriend since middle school, she had yet to experience her first time.
The most she had done sexually was kissing and light physical contact.
After exchanging a brief greeting with me, she didn't initiate any further conversation.
It was a natural reaction.
She seemed curious about the high school I had mentioned, but striking up a conversation with someone she had just met today wasn't easy—especially between opposite sexes.
However, there was always an exception wherever you went.
"Oppa."
At the voice calling out to me, I turned my head while pulling out the writing materials I had hurriedly brought.
"Yes?"
The source of the voice was Kim Ha-rin, Ji-ah's best friend, sitting right next to her.

Ha-rin was sitting with her feet up on the chair, curled up as she looked at me.
Meeting her gaze, I naturally took in her appearance as well.
Short hair that reached just below her neck.
Bangs slightly parted to reveal her forehead.
Light brown hair and matching eyes.
She looked to be around 160 centimeters tall—an appropriate height for a woman—with a somewhat petite build.
A loose navy hoodie covered her modestly sized chest.
Black stockings peeked out from under checkered short pants.
Unlike the long hair she had in her high school photos, it was now short, and she wore glasses with a white frame.
Her overall impression was that of someone outgoing and easy to get along with, regardless of who they were.
In contrast to Ji-ah, who seemed pure and calm, Ha-rin radiated a bright, approachable energy.
'Birds of a feather flock together. She's pretty too.'
Her looks were good, and with her bright personality, she probably had quite a bit of popularity among the guys as well.
[Kek… So it'll feel even better when you turn her into a puppet and fuck her, right?]
Guide's words stirred a lewd feeling in me, and the image of her taking off her clothes in the dressing room flashed through my mind.

Her large areolas on top of her perky breasts.
The way her chest had slightly spread apart when she pushed her shirt aside was still vivid in my memory.
Through the information provided by the company, I knew everything about her—not just her naked body, but her likes and dislikes, her family situation, and her past.
If she ever found out about my stalker-like knowledge of her, the only things she would send my way would be contempt and disgust.
But right now, she was smiling and treating me kindly.
That immoral gap sent a chill down my spine.
"I'm a year younger than you, Oppa. So you can speak casually with me. Not just me—everyone here probably feels the same way. A lot of us came straight to university after graduating high school."
"Ah… I see."
"I told you to speak casually."
"…Should I?"
I knew she was sociable, but I hadn't expected her to be this forward.
The perfume was probably playing a part, but Ha-rin's natural friendliness seemed to be the bigger factor.
'Maybe this will be easier than I thought.'
Originally, I had planned to approach Ha-rin first and take my time.
But if she was coming to me like this, it was all the better.
"Oppa, you said you graduated from Hangyeong High, right? I went there too."
"Oh, really?"
While pretending to be surprised, I glanced sideways and noticed that Ji-ah was also paying attention to our conversation.
"She went to Hangyeong High too. Oh, and by the way, she's my best friend."
At Ha-rin's introduction, Ji-ah gave a shy smile and lowered her head slightly once more.
"Really? Nice to meet you! I didn't expect to run into my juniors here. Still, in this place, aren't you two my seniors? Looks like I'll have to make a good impression on you guys."
"Is that so? Now that I think about it, you're right?"
Ha-rin, realizing I was joking, let out a natural laugh.
She seemed to have a good sense of humor too.
"Who was your homeroom teacher in third year?"
"Do you know Bulldog?"
"…Ah, the math teacher? If he was your homeroom teacher, that must've been tough. He was always so strict about school rules for no reason."
Since I had planned to use our shared high school as a way to approach them, this level of prior research and memorization was only natural.
"Exactly. He used to make such a fuss about makeup every single day— Ahem, sorry!"
"Kekeke… That teacher hasn't changed at all. Especially strict with the girls, right?"
"Right?! And sometimes he'd throw those old maid hysterics—it was no joke!!"
Ha-rin's voice grew louder, as if she had a lot pent up.
"There was even a trend at Hangyeong High where people tried to guess when that teacher would get married. Still, I thought she'd be married by the time I graduated…"
When I spoke with a wistful, sympathetic tone, Ha-rin burst out laughing.
Even Ji-ah, who had been listening, smiled faintly in agreement.
"She still hasn't gotten married?"
"Yeah, her personality is a bit… you know? So it's only natural… Still, she was a teacher who cared a lot about us…"
"She was strict with students, but she also had a lot of affection for them."
"Hnnng— When you put it that way, I feel bad for saying something negative… Honestly, she helped me a lot when I was applying to this university. Ah, cancel that, cancel that. She's a good person. Our homeroom teacher will definitely marry a wonderful person someday! There, I've decided the outcome right here!"
"Haha!"
Until the actual class began, Ha-rin and I continued chatting about our school days.
Though Ji-ah didn't join in, she listened with interest to the stories from our shared high school.
[You're pretty good at this, huh?]
"Class is starting now."
Along with Guide's teasing voice, the professor announced the start of the lecture.
Ha-rin, who had been enjoying her conversation with me, made a disappointed face before suddenly turning to both Ji-ah and me.
"Oppa, do you want to eat lunch with us after class? Ji-ah, that's fine, right?"
"Sure."
Ji-ah nodded.
Now it was my turn to answer.
The answer was obvious.
"I'd love to. Then please take care of me, my dear juniors. As I promised earlier, lunch is on me."
"Kekeke! You're funny, Oppa."
Ha-rin reached out and playfully tapped my shoulder.
As the professor's lecture voice echoed through the room, the noise died down as if by magic.
[Aha— You said talking to girls felt awkward, didn't you? Well, of course it wouldn't. After all, you've been talking to a certain woman every single day.]
I wondered if it was just my imagination that Guide's sarcastic remark carried a hint of thorns.
Since I couldn't figure out why, I simply ignored it and casually checked my phone.
> Lee Ji-ah Affection: 8% — ※Brainwashing Impossible
> Lee Ji-ah Corruption State: 0% — (Stable)
Lee Ji-ah's affection toward me had risen slightly.
Meanwhile—
> Kim Ha-rin Affection: 23% — ※Brainwashing Impossible
> Kim Ha-rin Corruption State: 0% — (Stable)
Ha-rin's pink gauge was already nearly a quarter full.
All it took was a short friendly conversation…
It was unexpected.
[It might be a bit difficult, but I did say it would be easier to fill her gauge than the target's. Once again, the affection percentage only represents intimacy and how susceptible they are to brainwashing. It doesn't necessarily mean they like you romantically.]
Strangely enough, Guide emphasized that it might not mean they liked me.
'Anyway, the start is going smoothly.'
[Right? But doesn't it feel like things are getting interesting? The sight of that girl chatting so happily with the man who's planning to brainwash her and turn her into a pawn… I can't wait to see how she'll change later.]
Guide's words left a lingering sense of anticipation, and before I knew it, I found myself glancing sideways.
In contrast to Ji-ah, who was diligently taking notes, Ha-rin was yawning as she listened to the lecture with obvious boredom.
Imagining how that innocent, unknowing face would eventually turn vulgar and end up sucking my cock made blood rush to my lower body already.
