You Shouldn't Let Strangers Into Your House
Seems about right… or does it…?
On the monitor was a photograph of a man’s penis.
More precisely, Park Yuna had been staring hard at the room in the background when she muttered to herself.
This wallpaper and door… aren’t they the same as my building?
She tried to tell herself it was impossible, yet the background in the photo felt far too familiar.
Only part of it was visible, so she couldn’t be certain, but no matter how she looked at it, the suspicion that it might be the exact same building refused to leave her mind.
The landlady decorated the whole place to her taste, so the wallpaper and door designs are pretty unique… I think that’s what she said.
The deeper her thoughts sank, the darker the shadow between her brows grew.
If it really is the same building, then the only possibility is the upstairs neighbor, right?
Yuna lived in a five-story villa with two units per floor. As far as she knew, the only man living in the building was the college student in 201, directly above her.
She knew this because of a phone call she had received from the landlady several months earlier.
"Yes, ma'am. What's the matter?"
"Um, Yuna. I'm sorry to ask, but… a male student is moving into the upstairs unit. Would that be okay with you?"
"A man? I don't really mind. Why do you ask?"
"Right now the villa only has women living here. I was worried it might make people uncomfortable to have a man as a neighbor. Especially since you live alone, Yuna."
"Ah, I'm perfectly fine with it."
"That's a relief. He won't cause any trouble, so you don't need to worry."
"Yes. Thank you for checking with me."
She hadn’t heard anything more about other men from the landlady since then, so the only male resident was still the one upstairs.
Yuna looked at the photo again, her expression deadly serious.
If it’s the upstairs neighbor, then it’s the same guy who brought my misdelivered package earlier. So the person in this photo is…?
During that phone call months ago the landlady had said “male student,” and the face Yuna had seen looked like a college student around her own age.
And the text attached to the post said…
Is this for real?
The coincidence was too perfect to dismiss.
There was no definitive proof, yet the sheer precision of the circumstances kept feeding her suspicion.
Of course, her hope that the post might be genuine was completely in vain. It was nothing more than something someone had fabricated after accidentally picking up Kang Iseor’s friend’s phone, trying to farm attention online.
But Park Yuna had no way of knowing that.
If this is real… this is a total jackpot.
She had always dreamed of encountering a man with jaw-dropping wealth. She was confident she could seduce anyone, so she had simply prayed for such a man to appear before her.
What if the post she was looking at was true?
It would be an opportunity that would never come again in her lifetime.
Let me look a little closer.
She clicked to enlarge the photo, but nothing happened. Instead, she was greeted by a notice that the original post had been deleted for violating board rules.
This post has been deleted for violating community guidelines.
What the— it’s gone. Oh well. It was too good to be true anyway.
Even as she thought that, a lingering attachment remained. Maybe it was because she had glimpsed hope, however briefly—Park Yuna didn’t want to let go of even the tiniest possibility.
…Should I just go ask the guy directly? It’s not like I have anything to lose.
Once she made up her mind, all that remained was action.
Planning to settle it before her stream, Park Yuna immediately set her plan in motion.
Okay.
A short while later, when she climbed the stairs to the unit above, she was carrying a plastic bag filled with tangerines.
She rang the doorbell. The door opened, and the man who had delivered her package a few hours earlier appeared.
“Who is— Oh.”
“Hello!”
“You’re from 101, right?”
“Oh my, you remembered?!”
“Yeah, well… I saw you earlier because of the package.”
“Ah! Haha, right. That’s true, isn’t it?”
“…Is there something I can help you with?”
“I bought too many tangerines to eat by myself. And I wanted to thank you for bringing my package up, so I thought I’d share some. Here!”
“Ah… thank you. I’ll enjoy them.”
Any normal man should have reacted more enthusiastically when a woman this absurdly beautiful showed him goodwill.
Still, Park Yuna kept flashing her brightest business-like smile.
“Do you live alone?”
“Yes, I do.”
“That’s amazing! I live alone too! Since we’ve gotten to know each other like this, want to come over and eat tangerines together while we chat? Can I come in for a bit?”
In her mind, there was no such thing as a man stupid enough to turn down a chance to talk with a woman as charming as her.
But contrary to her expectations, the man’s face was filled with discomfort.
“I’m sorry. I’m not really in a position to let anyone inside right now.”
“Is it because you’re cleaning? I don’t mind at all! Or I can help you clean!”
“No, it’s fine. Thank you for the tangerines.”
“Um… enjoy them.”
“Sure. Take care.”
Click.
Beep-beep-beep.
It was the first time the sound of a door lock engaging had ever felt so cold and heartless.
What the hell? Is that guy gay?
The shock of failure hit her hard precisely because she had been so confident.
Even after returning to her own room, Park Yuna couldn’t shake off her stunned disbelief.
Does he have a girlfriend? The post I saw earlier said he didn’t…
It was still difficult to accept that her flirting had been completely shut down.
Although this was her first attempt at seducing a man, she had believed that someone like her would succeed without fail.
Even so, there was a chance that this man was the wealthy prince she had been searching for so desperately.
She absolutely could not give up here.
I’ll do my broadcast first, come up with a new plan, then go see him again.
“Who was it?”
When I returned to the room, Iseor noona—still naked on the bed—asked me that.
“The neighbor from downstairs. She said she bought too many tangerines and wanted to share. I brought her misdelivered package earlier, so she was thanking me.”
“She gave you tangerines? She seems pretty outgoing.”
“You could say that.”
Outgoing didn’t even begin to cover it. She had invited a complete stranger to come inside and eat tangerines while chatting.
Of course it was burdensome, and since I already had noona with me, I had no choice but to refuse.
Still, being interrupted right in the middle was incredibly frustrating.
I immediately climbed back into bed and pulled noona into my arms.
“We still have some time, right?”
“I have to prepare for my broadcast, so I need to leave by then.”
“Then how long can you stay?”
“…Two hours.”
Aha. So she was asking me to fuck her for the next two hours.
I freely interpreted noona’s words and kept slamming my body against hers until time no longer allowed.
Ding-dong. Ding-dong.
Thirty minutes after noona, who had been enthusiastically playing fusion with me, went home.
I was busy editing a game review video I planned to upload to YouTube when the doorbell rang.
Is it Iseor noona?
Maybe she had left something behind.
Without thinking much, I left my room and opened the front door.
“Who is— Huh?”
“Ehehe. Hello again.”
The woman from the downstairs unit was standing outside the door once more.
Exotic and beautiful features, plus a chest that kept drawing my eyes.
I never imagined I would see this sight three times in one day.
“What brings you here this time…?”
“I’m sorry for coming back again… hehe.”
She looked embarrassed yet kept giving me playful winks.
It was a smile so pretty it was hard to look away from, but that wasn’t the important part.
Why is she being so friendly all of a sudden? She wasn’t like this when I returned her package.
“Actually, I have a favor to ask…”
“A favor?”
“My shower at home is broken, so I can’t wash. I’m really sorry, but could I possibly shower here?”
“You want to shower here?”
Now that I looked, she was carrying a basket. It probably contained a change of clothes and shower supplies.
But something felt off.
Why would she come all the way upstairs when she could have just asked the neighbor right next door?
“Couldn’t you ask the people next door…?”
“N-next door? Um, well… Oh! I just went and they weren’t home!”
“Ah…”
Because I had spent too much time with Iseor noona, I needed to hurry with the video editing. This was inconvenient.
Even if I had had time to spare, letting a woman I didn’t know into my house to shower felt uncomfortable.
“Still, a shower is a bit…”
“When you brought my package earlier, you seemed like a really nice person, so I thought I could ask…!”
“I see. But still—”
“Please! I have a constitution that makes me sweat a lot. If I don’t shower I can’t sleep. Pretty please?”
Whether or not the claim about not being able to sleep was exaggerated, there were even tears glistening beneath her green eyes.
She was so pretty that the ordinary conversation we were having felt surreal.
But no matter how beautiful the other person was, the situation wasn’t ideal, so I was about to refuse—
“I’m begging you! Please…!”
Seeing her desperate expression and the tears that had grown even larger, I couldn’t bring myself to say no.
If I refused and it caused any bad rumors, it might put the building owner—noona’s mother—in a difficult position.
“…Just a shower, and then you leave.”
“Really? Thank you so much! You’re an absolute angel!”
The woman who had been on the verge of tears brightened up in an instant.
Feeling uneasy, I let her inside. Then, as if she had just remembered something, she spoke again.
“Oh, right. After I shower, I have a habit of not drying my body with a towel and letting it air-dry naturally. I heard it’s better for skin care if the towel touches my skin as little as possible.”
“Excuse me?”
“I’m really, really sorry, but could you stay in your room until I say it’s okay? The bathroom is humid, so I need to come out to the living room for my body to dry properly… Hehe.”
Was she the type to ask for two things after you gave her one?
I was already starting to regret letting her inside.
Still, I did need to stay in my room to edit the video anyway, so it wasn’t a huge problem.
And since we already knew where each other lived, she probably wouldn’t steal anything.
“Fine. I’ll be in my room, so call me when you’re done.”
“Mmm~”
Park Yuna, having finished her shower in Han Jihoon’s bathroom, stepped into the living room.
Completely naked, water droplets dripped from her bare skin.
Hehe… Perfect. Everything went according to plan.

A satisfied smile spread across her face.
The brilliant idea of borrowing the shower, the flawless acting that had completely fooled him, and the meticulousness of actually taking a shower instead of letting her guard down even after safely entering the target location.
On top of that, she had washed away the sweat from her broadcast—an added bonus.
She was so impressed with herself she could barely stand it.
Oh my god, am I actually a genius?!
When the self-loving Park Yuna excitedly waved her arms around, her massive watermelon-like breasts danced along with the motion.
He definitely stared at my chest earlier, right? Men really are all the same. Anyway, he still doesn’t know I used to be a child actress, does he?
Her eyes turned toward the door of the room Han Jihoon had disappeared into.
Thanks to the genius lie about needing to air-dry naturally, the man wouldn’t come out until she gave the signal.
That was her limited window to confirm whether the forum post she had seen was true.
I originally planned to chat and subtly probe, but he wasn’t easy to handle, so I had no choice. I’ll just take a quick look around and leave.
She stopped in her tracks just as she was about to move.
…Wait. If I walk around dripping water like this, won’t I leave footprints and get suspicious?
She grabbed a towel from the bathroom, wiped herself dry, then came back to the living room.
Now it was time to find proof that the man was one of the top ten richest people in Korea.
That proof might be in the room he was currently in, or it might not exist at all. But since this was the only unit above hers, she had to do her best with what she could.
Starting with the small room!
With a tense expression, she began thoroughly searching the space.
The closet, drawers, pockets of hanging clothes—anywhere her hands could reach.
She knew what she was doing was a crime.
Her heart was pounding wildly at doing something this bad for the first time in her life.
Yet she had her own desperate reasons, so she moved busily with earnest determination.
Nothing particularly noticeable…
With no other choice, she moved to the living room and began searching again.
Nothing here either. So that post really was fake…
Just in case, she searched all the way to the kitchen. That was when she discovered something unusual in a drawer beneath the sink.
…A gift box?
A box wrapped with a pretty ribbon sitting under the sink of all places—it was suspicious.
In truth, it was the Schrödinger’s Gift Box that Han Jihoon had been keeping to give to Kang Iseor, but Park Yuna had no way of knowing that.
…
She glanced once at the room where the owner of the house was hiding, then quickly untied the ribbon and lifted the lid.
W-what is this…?
Inside the box were bank books.
Not just one—there were so many that she couldn’t even see the bottom of the box.
When she opened one of them, Park Yuna couldn’t help but let out a silent scream.
How many zeros is that? Ten, hundred, thousand, ten thousand, hundred million… t-ten billion?!
The shock was so great she nearly fainted on the spot.
Ten billion won in a single bank book. So that internet post had been real after all.
— Excuse me?
"Hik! Y-yes?!"
— Are you still not finished?
"Just a moment! I just need to put my clothes on!"
She had to put the box back exactly as she found it before she aroused suspicion, but her hands were shaking so badly she couldn’t tie the ribbon properly.
In the end she gave up on the ribbon, simply closed the drawer, and rushed to get dressed.
Hurry! I have to get dressed fast!
“Haa… I-I’m dressed now! You can come out!”
At Park Yuna’s words, the firmly closed door opened and Han Jihoon stepped into the living room.
“Now that you’ve showered, we’re good, right?”
“Yes! Thanks to you, I think I’ll be able to sleep comfortably! Thank you so much. Goodbye!”
She left Han Jihoon’s house doing her best to act natural.
Her legs trembled the entire way down the stairs and she nearly fell several times, but she somehow managed to keep her balance and make it back to her own home.
“Haa… haa…! It was… it was real!”
She still couldn’t believe the numbers she had just seen.
Just one of the many bank books in that box contained a full ten billion won.
If a random one she picked up had ten billion, the others surely held even more. And besides the stack of bank books, he almost certainly had enormous assets in stocks, coins, and other investments.
This is my chance! I have to seize it no matter what! If I can just seduce that man…!
“If I can just seduce him…”
Her shoulders, which had been lifted high with excitement, suddenly slumped.
…Is this really the right thing to do?
Although she acted cheerfully, she was still a twenty-one-year-old adult.
She wasn’t unaware that what she was about to do was wrong.
Snooping through someone else’s house was obviously unacceptable, and she knew that approaching a person purely for their money would inflict deep emotional wounds.
She had gotten overly excited by the fact that the opportunity she had only imagined had finally arrived, and ended up committing an act she should never have done.
It was only natural that her belatedly returned sense of reason plunged Park Yuna into agonizing conflict.
If I have that man, I can live like I used to. But doing something like this…
No matter how long she thought about it, she couldn’t easily escape the dilemma.
Yet she had a personal reason that made it difficult to give up this opportunity.
R-right. Even if I approach him for the money, if that man marries me, I can just make him the happiest person in the world, right?
Having come up with her own method of atonement, she strengthened her resolve.
Park Yuna had no idea that the man was the owner of an app beyond her wildest imagination.
