"Dinner will be ready soon."
Their mother completely ignored Hibiki's shouts and reminded them.
"Okay, we'll be down in a bit."
Hayato, carrying large and small bags and his sister, replied.
Hibiki, whose neck was being held, saw her plea for help ignored, and her gaze immediately became mournful and powerless, like a dead fish, as Hayato embraced her and walked to her room.
Then, she watched blankly as Hayato calmly opened the room door, as if he were returning to his own room.
"This is my room!"
"My sister's room is my room, and my room is still my room."
Hayato nodded confidently.
"Are you Gian?! Even Gian wouldn't do this to his own sister!"
Hibiki, unable to contain her anger, began to struggle.
"Sister?"
Hayato released his sister, feigning a blank expression as if he hadn't understood, and looked around.
"Where? All that's here is a keyboard, an amplifier, and an idiot, isn't it?"
"I won't teach you then."
Hibiki, released, walked into the room, turned to face Hayato, and said coldly with her arms crossed.
It seemed she wasn't that foolish; she had clearly guessed her Big Brother's intention, and for a moment, she held the upper hand, putting on a stern face.
"Oh~"
Hayato nodded. "Wait for me."
He said, then turned and left the room. Hibiki curiously poked her head out to watch him go down the stairs.
A moment later.
Hayato looked at his sister, who was sitting angrily on the light blue bedsheet, still in her school uniform, and extended a hand.
In his hand was a freshly bought box of pudding.
"Pudding."
He had a fawning smile on his face.
"What do you take me for...? I won't be tricked into doing hard labor for a little food."
Hibiki sighed and pouted.
Tch, she's usually so stupid, but she gets smart at crucial moments. I'll have to pay a hefty price.
Hayato grumbled inwardly, but the fawning expression on his face remained unchanged. He extended another hand, with several slips of paper in his palm.
And it truly was his ultimate weapon. Hibiki's gaze swept over it, then lingered casually on his hand, her small head nodding as if counting the slips, before a barely concealed smile appeared at the corner of her mouth.
"Well... teaching you isn't impossible."
She took the slips of paper with deceptive speed, not forgetting to lay down a threat.
"Let me tell you first, if you're too stupid to learn, I won't be responsible, okay?"
Even while asking for help, Hayato still scoffed upon hearing this.
"Heh."
Hibiki immediately bristled, waving her small fists, and glaring at Hayato through gritted teeth.
"How dare you scoff! Just you wait!"
...It was dinner time.
The siblings came downstairs.
One was deep in thought, the other followed her Big Brother, swaying as if she had lost all hope in life.
"What's wrong with you two?"
Jinpei, the head of the Ishikawa Family, who had just returned, sat at the dining table, took a small sip of sake, and was about to start eating, but he looked up at the abnormal appearance of the siblings.
Hayato snapped back to reality and said,
"Oh, right, I joined a Band today. I'll be coming home later from now on."
Jinpei nodded, indicating he had no objection, then showed a hint of a smile.
"Are you planning to start a harem as a Band member? Not a bad idea."
He said this with a proud expression that suggested, 'You're still too green.'
"No, I can't accept a harem started with such third-rate methods."
Hayato sat in his seat, shaking his head, dismissive of his father's idea; those were outdated things.
After his sister sat down, her first words were directed at Jinpei, her father.
"Dad, do you know your son is a Pervert?"
Jinpei was startled, blinking in confusion, with an expression of surprise that seemed to say, 'Why are you only finding out now?'
Seeing her father's foolishness again, where all his thoughts were directly shown on his face, Hibiki, annoyed, simply didn't talk to him and instead called out to her mother, who hadn't yet come out of the kitchen, in a spoiled tone.
"Mommy~~"
"Coming."
Shizuka wiped her hands and walked out of the kitchen, smiling.
Seeing his wife arrive, Jinpei's expression became slightly serious; he dared not show the sly look he had just shared with his son.
Hibiki asked Shizuka with a serious expression.
"Is Big Brother really Dad's son?"
Hearing this earth-shattering question, the two men of the Ishikawa Family stared blankly at Hibiki, then at each other, and finally turned to look at Shizuka.
The mistress of the Ishikawa Family, who was about to pick up her chopsticks, froze her smile, then narrowed her eyes.
"Hibiki, don't you want your allowance this month?"
Facing the allowance question, Hibiki immediately regained her intelligence.
She neatly and politely put down her chopsticks, pushed back her chair, walked to the side, and knelt down.
"I'm sorry!"
Watching his sister in this state, Hayato stroked his chin. It seemed his sister also had the potential to become a Pervert... "But it's too exaggerated, why is Big Brother such a Pervert?"
After Hibiki explained, her parents understood the situation.
It was just a matter of going from not being able to play the piano at all to being able to play a piano piece in a few minutes.
They were already used to it.
"That's just a thinking ability infinitely superior to your almond-sized brain. Please call it intelligence; it's not being a Pervert."
Hayato ate his meal properly. He had his own views on what constituted a Pervert, and it wasn't just anything strange being called a Pervert.
"But Big Brother, you are a Pervert, aren't you?"
Hibiki said with certainty.
After all, this was what her Big Brother had called himself for over ten years.
"Of course, I am a genuine, upright and honorable Pervert."
Hayato replied proudly, never changing his name or his ways.
Seeing her son like this again, Shizuka sighed. She began to worry about her underage son's lifelong prospects.
"Hayato... no girl will like you like this, and you won't even be able to start a harem."
Hearing his mother say this, Hayato boastfully recounted the events of the afternoon.
"Oh, right, speaking of girls, today I met two angels! They stayed with me for over an hour, helped me buy books and a keyboard, it was great~"
He happily swayed from side to side.
Hibiki slowly put down her chopsticks, clasped her hands, and mourned in silence.
"Poor salesladies, I hope they encounter happy things in the future to forget today's tragic experience."
She didn't take her intelligent Pervert Big Brother's words seriously at all.
Hayato turned to look at his parents, and seeing that they also agreed with his sister's opinion, he quickly finished the rest of his meal.
Then he picked up his rice bowl and stood up.
"Within two months, I'll definitely show you my harem! Also, Hibiki, finish eating and come up quickly."
"Eh… so even the excellent Pervert-sama needs guidance from my almond-sized brain, huh?"
Hibiki slowly swayed her head, holding her rice bowl, looking as if she had her brother completely under her thumb.
"If you don't work, give me back the payment."
Hayato didn't mind at all. Although it was just the beginning, the hardest part of music is the start.
The rest didn't need Hibiki.
In other words, his sister's utility value was gone; she could go sit on the sofa like a puppet and foolishly watch TV.
"I'm coming right away!"
Hibiki immediately sped up her chopstick movements.
