Zain quickly raised his hands, trying to explain the whole situation to her.
"Wait! I can explain—"
But before he could continue, his sister rushed toward him.
He already expected to get slapped or at least screamed by her.
But unexpectedly, she hugged him instead.
Tightly.
"Zain! Are you okay? Did he hurt you?"
Zain blinked, completely thrown off. What the hell?
"I'm fine. He didn't hurt me at all."
"But still, aren't you going to ask me what happened here?"
His sister soon saw the corpse lying on the floor before tilting her head.
"Oh."
Zain watched as she stared at their dead father.
Her expression was blank for a moment.
She simply shrugged.
"He must've passed out from drinking again, right?"
Zain narrowed his eyes.
There's no way she's that dense..., right?
Before he could say anything, she casually pulled out a knife from her bag.
She then stabbed their father's corpse. Without any hesitation.
Once.
Twice.
Over and over.
Zain stared in disbelief as she continued to stab their father's dead corpse.
Finally, after several deep thrusts, she pulled the knife out, flicking the blood off onto the floor.
"Now that he's dead... We should be safe, right?"
Zain just stood there. His mind was completely blank.
"What... the actual fuck?"
His sister suddenly turned toward him and sniffed him.
"You stink. Go take a bath."
Zain, still processing what just happened, couldn't even react.
His sister pushed him out of the room.
"I'll handle this and I'll make some delicious dinner."
Zain simply nodded like a puppet.
He went toward his room on autopilot.
Once inside, he sat on the edge of his bed, staring at the wall.
His mind finally caught up, frowning him.
"What the hell just happened?"
---
Zain stepped into the shower, letting the warm water run down his body as he processed everything.
His sister... was already too far gone.
She hadn't even flinched when she saw their father's corpse.
Instead, she added a couple of extra stabs for good measure, like she was just finishing a chore.
Zain smirked. "I think I like this girl."
Watching her stab their father without a shred of emotion had been... amusing.
If nothing else, it confirmed one thing. She had no love for that man.
Maybe she even hated him more than I did.
He ran a hand through his wet hair, chuckling to himself.
"This family might not be so bad after all."
Once he finished showering, he dried off and got dressed, heading toward the kitchen.
The aroma of her cooking could be smelled through the air.
It was surprisingly pleasant despite the situation.
His sister stood at the stove, casually stirring something in a pot.
She glanced at him as he entered. "Took you long enough."
Zain smirked, running his hand through his damp hair. "Just making sure I'm clean."
She chuckled, turning back to the food. "Good. Would be a waste if I had to throw you out with the rest of the trash."
A minute later, she placed a plate in front of him. "Here you go."
Zain took a bite. It was surprisingly delicious.
"Damn. This is good."
He looked up at her. "You're a great cook, sis."
She smiled, pleased with herself. "Of course it is. This is a special day, after all."
Zain raised his brow. "Special?"
She shrugged. "It's the day we finally got rid of him."
Zain set his spoon down, glancing at her. "Speaking of which... what did you do with the body?"
She grinned. "Oh, don't worry about that. I chopped him up and fed his remains to the neighbor's dogs."
Zain blinked and simply nodded. "I see."
His sister didn't react, humming softly.
She continued eating, as if she had just talked about taking out the trash.
Zain continued eating as well, saying nothing more. This girl was truly something else.
Once they were done, he placed his utensils down and stretched. "I'm heading to bed."
His sister nodded, wiping her mouth with a napkin. "Good night, Zain."
Zain gave her one last look. "Good night… sis."
As he left for his room, one thought remained in his mind.
"Yeah… I'll let her calm down first. We'll talk later."
---
Zain lay on his bed, staring at the ceiling, thinking about his current situation.
His system. Hero Hacker.
Just what exactly could he do with it?
The name suggested he needed a hero to test it on. But finding one… that was the real problem.
Heroes were everywhere in this world, but that didn't mean he could easily meet one.
"Tch. Where the hell do I even start?"
He sighed, closing his eyes.
But just as he was about to sleep, he suddenly heard something.
A muffled cry.
His brows furrowed. The sound came from the other side of the wall.
His sister.
Zain smirked. "So, she finally broke down, huh?"
He had seen this pattern before. One of his strongest demonic generals from his past life had gone through something similar.
She, too, had been raised in a broken home.
A bad family that had left deep scars in her heart. And just like his sister, she had killed them all.
But after it was done?
She had collapsed. Cried for hours.
And when she finally stood up again, she was different.
She was stronger and sharper. She had freed herself from her past shackles.
Zain leaned back against his pillow, chuckling softly. "So this is what's happening to her now."
Let her cry. Let her break down.
Because once she was done, she'd emerged stronger and better.
He smirked, turning onto his side. "Having a sister in this world isn't so bad."
At the very least, this world would be far more interesting with some company.
Meanwhile, in her own room, her sister sat curled up on her bed.
Her body was trembling as quiet sobs escaped her lips.
Her fingers clutched at her own arms as she muttered, over and over—
"Why did I do that…?"
"In front of my brother…?"
She dug her nails into her skin, thinking about what she had just done earlier.
