Possessed and Gained a Sister
“Fuck, where the hell am I..”
My eyes were swollen from crying so much last night. I could barely see straight.
What I was staring at wasn’t the low ceiling of my cramped room, but a high-ceilinged space bathed in bright light.
“LED..”
LED fixtures were too expensive to install in a rented place that wasn’t even mine.
In other words, this wasn’t my room.
A completely unfamiliar room, yet my body insisted it wasn’t strange at all.
Without even thinking, I naturally pulled out my phone to check the time.
July 8, 2023. 7:00 AM.
Yesterday was the 7th, so the date checked out. Did I get blackout drunk and break into someone else’s house?
My thoughts, still sluggish from leftover alcohol, suddenly accelerated.
Sensational headlines like [Detective Caught Living as a Parasite in Someone’s Home] flashed through my mind.
Just then, the savory smell of cooking drifted in from beyond the door. A delicious aroma… one I’d missed terribly. The scent of rice cooking and the sharp, spicy fragrance of stew simmering.
No way…
I carefully opened the door. A hallway led to the living room. It was a huge house I’d never even dreamed of—something that would take a detective over a century to afford.
Yet in this alien space, the smell I’d longed for wrapped around me.
Stepping out cautiously, one foot at a time, I moved forward.
The living room was enormous. Morning sunlight poured across the floor all the way to the kitchen through the massive glass windows.
The TV in front of the living room was playing the morning news. Someone sat in the massage chair, reading a newspaper.
When I cautiously turned toward the kitchen, a woman with long hair and an apron was busily preparing breakfast.
I recognized her instantly.
“Mom..”
It was Mom. She looked exactly the same as the last time I saw her, smiling softly as she tasted the stew to check the seasoning.
I approached her carefully and hugged her from behind, apron and all.
“Oh my! You startled me.”
“Mom..”
That voice I could never forget. Hearing it again after so long, I couldn’t hold back my emotions. Tears welled up, but I forced them down.
“Make some noise when you walk around.”
“Yeah..”
Mom turned back to the stove and continued prepping ingredients with quick, practiced movements.
She finished cooking in no time. Then a strange thought struck me—not fear or shock, but pure confusion.
Was Mom always this tall?
I was 185 cm. Mom was 167 cm. Yet the height difference felt off. I was only a few centimeters taller than her now. Then it hit me.
Mom looked exactly the same because… the person reflected in the mirror was a high school student.
“Mom.. how old am I?”
“What are you talking about? You’re seventeen.”
Seventeen? I was thirty. That couldn’t be right!
But my body didn’t look thirty at all. No stubble, smaller frame—it was exactly how I remembered myself at seventeen.
The knife scars, bruises, and hard-earned muscles from my police days had all vanished, leaving behind a plain, unremarkable body.
Haha—
This wasn’t right.
Something was wrong. This wasn’t regression.
Of course it wasn’t. The time was the present, both parents were alive, and even when they were alive before, we’d never lived in a house this expensive.
Something was seriously fucked up. System—!!!
I screamed it inside my head. If I’d actually possessed someone inside a novel, this kind of bullshit made sense.
> [Hello.]
That’s it!
> [I do not understand the command.]
What the hell is going on?
> [You have transmigrated into this novel.]
Who are you?
> [I am the System granted to you as a transmigration bonus.]
Do I have to ask for every single thing? Shut up and tell me everything you know.
I’d spoken without thinking, just like back in my detective days.
Old habits die hard.
> [The novel’s title is “Became the Academy’s Strongest, Ended Up with a Hundred Wives.” You have transmigrated as Kang Hyunsu. As a transmigrator bonus, you have received the System along with various items and skills.]
> [I hope you achieve everything you desire within this novel.]
What the hell is this supposed to mean..
Creak—
The door to the small room opened. I’d thought it was unused, but apparently not.
“Mom, food.”
“Alright, Ria. Go wash your face first.”
Fuck! What the hell was that? A girl with long black hair walked out slowly in pajamas. The top was so loose that her chest was completely exposed. She scratched the spot like it itched.
Some random woman was walking out of our house.
I was an only child. I had no siblings.
“Who is that? That girl?”
System—
> [She is Kang Ria, Kang Hyunsu’s older sister.]
Kang Ria..? That name sounded familiar..
Wait… hold on. Ria as in the novel’s Water Witch, Kang Ria?
> [Correct. If you wish to read more of the novel’s contents, please use the bonus novel access granted to you.]
Where is it.. where..
Found it. {Side Story Chapter 46: Kang Ria}
Kang Ria. A magic-type hunter who would become the Minister of Magic after graduating from the academy. She was destined to become the original protagonist Lee Taehyung’s 46th wife.
Below that were all her settings, weaknesses, likes, and episodes involving the protagonist Lee Taehyung.
The protagonist’s 46th wife?
I vaguely remembered the episode. She resisted the protagonist to the very end, but he used hypnotic magic on her and made her fall. She wasn’t really a wife so much as a sex slave. The protagonist never gave love to the women he tamed with hypnosis, even if he called them wives. They were just tools to be used when needed and discarded.
That’s exactly why I hated the protagonist. Readers might cheer because they’re all perverts, but it was clearly a crime.
“That pitiful girl is supposed to be my sister..”
I had to protect her no matter what. I’d finally gotten my family back together.
Mom’s voice called everyone from the kitchen.
“Breakfast is ready.”
Warm rice and spicy stew. I couldn’t remember the last time I’d eaten Mom’s cooking. Tears threatened to fall. Having an awkward new sister was weird, but overall, this life wasn’t bad.
Still, what exactly had I possessed?
The name was the same, the family was the same—except for the sudden appearance of a sister.
I had zero intention of going around ruining female students like the original protagonist.
All I had to do was keep my sister away from him, right?
That was when a notification from some couple app went off.
Ding!
A storm was rolling into my peaceful transmigration life.
[1000-Day Anniversary Heart Heart]
It was a couple app. I had a girlfriend?
I opened the app.
[1000 Days with Seoyeon]
Seoyeon? That was my ex-girlfriend’s name. Why was it here?
When I read the diary entries written in the app, everything became clear.
[July 1, 2023]
Our 1000-day anniversary is coming up, but she sent a message saying we should break up. I can’t believe it. Seoyeon, who always smiled no matter what I did and was so kind, suddenly wants to break up? That’s impossible! I’ll ask her seriously at the academy tomorrow.
[July 2, 2023]
Seoyeon clearly told me she wanted to break up. That she didn’t like me anymore. She cried and ran off somewhere. I couldn’t find her all day—she kept avoiding me.
[July 4, 2023]
I happened to see Seoyeon. She was walking with Taehyung. Even when he touched her all over, she just stood there quietly. I ran over and told him to stop, but he punched me and kissed Seoyeon right there. Taehyung kissed her skillfully while groping her chest.
When the kiss ended, Seoyeon’s face and body were flushed. Breathing heavily, she told Taehyung she loved him.
Something inside me broke. I raised my fist and charged, but he subdued me instantly and I blacked out.
[July 5, 2023]
While cleaning the art room with a heavy heart, someone came in. It was Seoyeon and Taehyung. When Seoyeon tried to pull away, saying she didn’t want to, Taehyung grabbed her and kissed her. She stopped resisting and obediently offered her body.
I stepped in again. Got beaten up and blacked out again.
Still, I did the right thing.
[July 6, 2023]
Seoyeon called me out to a back alley. In that deserted place where no one would come, she spoke.
“If I said I don’t want to and want to break up, why do you keep interfering?” she snapped. I couldn’t say anything.
Then Lee Taehyung appeared.
His lackeys grabbed my arms and threw me down. With so many people holding me, all I could do was look up from the ground.
Seoyeon suddenly approached Taehyung, kissed him, and started taking off her clothes. Her body was beautiful. Smooth, without a single muscle, pale. Taehyung touched that body indiscriminately. He grabbed her tightly and kissed her.
I could only watch. Sticky saliva dripped from Seoyeon’s mouth onto the floor as she tried to remove her bra. Taehyung stopped her. Then Seoyeon, who had never once acted cute with me, clung to Taehyung and begged him to do more.
I screamed. And blacked out again.
[July 7, 2023]
This is probably going to be my suicide note.. I don’t know. I just bought pills. A bunch of sleeping pills.. I’m going to take them and die. I loved you, Seoyeon.
Fuck, what the hell did I just read? Fuck? I got NTR’d. And badly—right in front of my eyes. The original soul of this body committed suicide, and I took over.
A system message appeared before my eyes.
