The Sister's Reunion
That means I'm also my younger sister's older brother.
"Come out for a moment."
I sent a subtle suggestion toward Seo Moon-min-hye, who was training inside the Seo Family Estate by swinging her sword. It wasn't anything as dramatic as brainwashing. I simply planted the desire to step outside for a bit, enough to make her act on it without realizing why. If brainwashing meant total domination, suggestion was merely guiding someone's actions.
"Ah~ This is so stuffy."
I watched as Seo Moon-min-hye emerged from the mansion door. In this life, she was currently fifteen, Seo Moon-hyun was fourteen, and she—who was two years younger than me—was now thirteen. Her beauty was only just beginning to bloom, so she still gave off a cute impression rather than a stunning one. Even so, her already remarkable looks were evident. With her blue hair and blue eyes, she clearly belonged to the Seo family.
'I could just reveal myself like this.'
But she wasn't alone. Two men in suits standing guard at the Seo Family Estate had slightly bowed their heads toward her.
'Obstacles need to be removed.'
With that thought, I lightly waved my hand. In that instant, the two men froze in place. I had simply used time-stop magic, freezing the moment where they stood.
"Huh?"
As the flustered Seo Moon-min-hye looked around, I slightly manipulated the space between us.
'Dimension Creation.'
I created a temporary space belonging to another world and enclosed only the two of us within it. Seo Moon-min-hye and I now stood in a peaceful flower field of my own making.
"It's been a while, Min-hye."
I greeted her with the gentlest smile I could manage. Yet Seo Moon-min-hye, startled by the sudden transformation of her surroundings into a flower field, couldn't hide her tension as she stared at me.
"W-Who are you? W-Where is this place?"
Smiling at the nervous girl, I answered.
"My name is Seo Moon-jin. I'm your biological older brother who was expelled from the Seo family. And this is a space I created."
"A created... space? Wait, and... my brother?"
As the bewildered Seo Moon-min-hye watched, I approached while keeping my gentle smile. She flinched and took a small step back, but I quickly caught up and stroked her head.
"Eek."
"You've grown so much, Min-hye."
Seo Moon-min-hye looked wary, as if she couldn't believe my words, and tried to retreat again. But she couldn't escape my hand that easily followed her.
"Are you... really my brother?"
She spoke to me politely, suspicion clear in her eyes, but I wasn't hurt. This was merely a place to plant the seeds of my plan. Besides, for her, this moment was our very first meeting.
"Yes. If Father, who expelled me from the family, hears the name Seo Moon-jin, he'll throw a fit... but if you make the effort to look into it, you'll find out. Seo Moon-hyun seems to be living just fine, having forgotten all about me."
At the time, four-year-old Seo Moon-hyun had been taught that an older brother who—unlike himself, who had awakened magic power—was an incompetent was nothing more than a 'subordinate.' He had naturally learned to treat me as one, so he only showed the slightest courtesy, as if dealing with a servant. It might seem strange to hold a child responsible, but that was something only those who had never experienced it would say. And even if that had been the case back then, what came afterward was far more decisive.
'When I was suffering from hunger and cold, he never even worried.'
He simply forgot. That was all there was to it.
Anyone who mocked my current feelings could bet every strand of Seo Moon-hyun's hair that if they tried living on the streets as a five-year-old, enduring cold and starvation, they would retract their criticism within three days.
And even if it had been that way when we were young, even now that he had grown up, he still hadn't worried about me at all. He had forgotten me completely. To him, I was an existence that needed to disappear.
No—more accurately, an existence that needed to die.
"Seo Moon-jin..."
As Seo Moon-min-hye muttered my name as if trying to remember it, I smiled faintly.
"You were only three back then, so you probably don't remember me well, right?"
"No... I have some faint memories."
Looking into her eyes, I read her thoughts.
Is he really my brother? It feels like some memory is coming back... But expelled from the family? Why exactly?
"Shall we talk for a bit?"
"...Yes."
Since he might really be my brother, I should at least hear him out.
She hadn't reached the practical conclusion of quietly obeying because I could kill her anytime. Thanks to her faint memories of me, however, she remained wary yet seemed to feel a confusing sense of gradually believing my words.
"My power has grown much stronger. Strong enough to create something like this. But this is a power I only recently obtained after long preparation. Before that, I was an incompetent who couldn't even awaken magic power."
As I spoke, I lightly touched my hair. Unlike the Seo family's blue hair, mine was black—completely unaffected by magic power.
"Ah..."
Seo Moon-min-hye wore an expression as if something was about to surface in her mind.
Come to think of it, it does seem like there was another older brother when I was little... and his hair was black.
Since she already had memories of my appearance, persuasion came easily. The fact that my overall features resembled Seo Moon-hyun's, despite the different atmosphere, helped even more. Even with different hair and eye colors, the similarity in our faces made her trust me further.
"I hate and despise the Seo family. But I have no intention of holding you responsible—you had nothing to do with it and were too young to remember. Still, since I'm your brother in name, if you ever face difficulties or truly need urgent help, call for me desperately."
While speaking, I subtly planted my imprint on her. It had no special effects; it simply allowed me to monitor her location in real time and immediately notice if she desperately sought me out—a rescue beacon, essentially.
"You'll help me?"
"Yes. And you can speak casually. Using polite speech with your brother feels strange, doesn't it?"
"Yes. I mean... okay. I'll do that, brother."
Seo Moon-min-hye's words meant she had acknowledged me as her brother. She wasn't 100% certain, but she was over 90% convinced. The slight hesitation in her tone suggested it wasn't complete certainty yet.
"Alright, then I'll send you back. Take care."
"Yes... brother."
She called me brother, but the awkwardness was obvious. I knew this awkwardness was only temporary. In the original story, Seo Moon-min-hye had been a lively, playful girl.
"This is a gift."
Saying so, I took out a wild ginseng from my dimensional space.
"Wild ginseng?"
It was one of the many elixirs I had secured in large quantities from the virtual reality game I played. Thanks to the editor removing the dimensional space capacity limit, I had ten million of each type. The editor's power—allowing me to modify a single-player virtual reality game with enough freedom for munchkin play—was truly incredible.
Even so, to me it was merely one elixir out of ten million. It possessed moderate effects, nothing excessive. In this world, however, elixirs were inherently precious.
"Brother, this... isn't this too much?"
Even the Seo family understood the value of elixirs, so her surprised expression was clear.
"It's fine. I can give this much as a gift to my sister."
At my words, I felt her favorability rise. As expected, nothing won favor quite like expensive and useful items.
After sending her back, I was certain she would now try to learn as much about me as possible. After receiving such a gift, how could she not be curious about the biological brother who gave her something so valuable?
'Seo Moon-min-hye.'
I called her name in my mind.
Though she was my biological younger sister in this life, that fact was honestly trivial.
'I'll make you mine too.'
I would take all the heroines. Among them was Seo Moon-min-hye—the younger sister character who, while not one of the main heroines, had been one of the major female characters. A cute little sister would become my woman once she grew into an adult.
I didn't care about the taboo of incest. The reason it was forbidden was the high risk of deformed children, but I could solve that problem. And unlike the original story, they would all reach a happy ending.
"Then the seeds have been sown..."
And more importantly, a subtle sense of rejection toward the Seo family—which had expelled her eldest brother—would take root in her heart. This small gap would create cracks in her unusually close relationship with Seo Moon-hyun, her second older brother, a bond that had carried a slightly dangerous atmosphere in the original work.
'In the original story, Seo Moon-min-hye was greatly shocked when she learned of Seo Moon-jin's existence.'
It was described that she had been the most shocked by his existence, even though she eventually cut ties because of his evil deeds. In the original, Seo Moon-hyun had shown a cold attitude toward Seo Moon-jin that surprised readers.
Instead of planting a negative image like in the original, I would give her only positive impressions of myself, making her lean toward me rather than the Seo family.
"...I'll also need an official identity and status."
