Robin took the thick gift, her clear, sapphire-like eyes blinking.
The fourteen-year-old girl was already showing signs of her beauty, with fair skin and soft silver hair.
Dressed in a simple white dress, she looked exceptionally clean and pretty.
She looked at the cover of the document, first stunned for a moment.
Then she burst out laughing.
"Brother, this gift of yours… is so you."
She chided him with a smile, yet without any displeasure.
Instead, she carefully hugged the document to her chest, as if holding a treasure.
"But, thank you, I know you must have put a lot of thought into it."
"I will… hmm, refer to it!"
"It's not a reference."
You corrected her.
"It's the optimal solution."
Looking at his sister's bright smile, the strings of your heart, usually taut from thinking and calculating, seemed to relax a little at this moment.
For you, planning everything for her and ensuring she walks the most correct and efficient path is the best protection and care. This is the order that family should have.
"Alright, alright, I know Brother is the best."
Robin solemnly placed the document on the table.
Then, she took your hand.
"Now, it's time for my gift! Follow me!"
You were led by her to the piano room next door.
Robin gestured for you to sit down.
She herself took a deep breath and sat down at the piano.
"This piece… doesn't have a name yet."
Her fingertips lightly touched the keys, her voice a little nervous.
"But when I play it, I'm thinking of you, Brother."
"Happy Birthday, Brother."
The piano music began.
The melody was unexpected.
It didn't completely conform to what you knew as the "optimal" structure, yet it had a strange, heart-touching power.
You listened quietly.
For the first time, you didn't subconsciously analyze its structure and technique.
The music was like a mirror, reflecting corners of your inner self that you hadn't fully explored.
It seemed… there wasn't only cold order there.
When the piece ended, the lingering notes resonated.
Robin looked back at you, a little uneasy, her fair cheeks slightly flushed.
"How was it, Brother?"
You were silent for a moment.
You stood up and walked to her side.
You reached out and gently pressed on the keys she had just played, feeling the lingering warmth.
"The structure is very bold."
"But the logic is self-consistent, forming a unique Harmony."
"It's very beautiful."
You added, this was an objective evaluation.
"I like it very much. Thank you for your gift, Robin."
This sentence seemed to carry a different emotion.
"It's good as long as Brother likes it."
Robin smiled happily; this was the best affirmation she had received.
[At 15, your standing within the family steadily improved.]
[To pursue her musical dreams, your sister began to leave Penacony and travel to other planets for musical activities.]
[You maintained contact through letters and communications.]
[You always told her in your replies to come back and see you more often, as Penacony was the safest place.]
[At 16, Gepard's power reached its peak.]
[You were seen as his future successor within the Oak Family, which was part of your plan.]
[Your sister, Robin, gained immense popularity outside, becoming a rising star.]
[At 17, Robin's songs spread across more star systems.]
[However, her success made you more worried about the chaotic and disorderly world outside Penacony.]
[That place was not like the family's dream, where order could ensure her safety. This sense of being out of control displeased you.]
[At 18, the year you officially came of age.]
[Gepard, who had become the Dream Master of Penacony, passed on the position of family head to you, witnessed by the entire Oak Family.]
[You stood high above, looking down at the family members.]
[From today onwards, as Sunday, the Head of the Oak Family, you will reshape this "Dream Star" with the absolute order you believe in.]
[Not for the family, but for… Robin.]
[At 19, after you took over as family head, a flood of complex affairs overwhelmed you, and your daily working hours exceeded 12 hours.]
[Yet, you never complained about the heavy workload, because this was your responsibility as family head.]
[However, an urgent letter from Acheron (assuming Aepselon is a mistranslation or placeholder) made you instantly drop everything you were doing.]
[The content of the letter was strikingly brief.]
[Your sister, Robin, had encountered an accident there.]
[Shot and wounded in the neck!]
[Although the letter mentioned that her life was not in danger, the words "vocal cords damaged, may not be able to sing in the future" still filled you with worry.]
[You immediately used your authority as family head to mobilize all resources, at any cost, just to ensure your sister could return to Penacony in the fastest and safest way possible.]
A few days later, in the Oak Family's private reception room.
The door opened.
You saw your sister, weary from her journey, return.
She looked very tired, her complexion much paler than you remembered, but she still tried to maintain the elegant demeanor befitting the Oak Family Head's sister.
She wore high-necked clothing, carefully concealing something.
But you still immediately caught sight of the faint outline of a wound on her skin, visible at the edge of the collar.
"Brother, I'm fine, you worried for nothing." Robin showed a slightly weak smile, "It was just a small accident, I'll be fine soon."
Your gaze, however, could not move from her neck.
That scar, even through her clothing and dressing, burned your nerves.
An indescribable emotion exploded in your chest!
It was towering rage.
It was the lingering fear after a narrow escape.
And even more… a cold sense of frustration at being powerless, even as the family head!
Reality had slapped you hard!
Harmony cannot protect her!
This chaotic universe cannot protect her!
As if sensing your silence and gaze, Robin tried to reassure you:
"You really don't need to worry, Brother. This time I was too careless, next time I will definitely be more careful."
Next time?
These two words pierced your mind like sharp needles.
Your heart suddenly jolted, there's a next time?!
Let her leave Penacony again?
Go again to those wild lands filled with unknowns and chaos?
Face again this danger that could take her voice, or even her life?!
No!
Absolutely not!!
At this moment, you began to consider how to ensure your sister's absolute safety—
Trust and support Robin's choice, using your authority as family head to provide her with the top-tier security.
Keep Robin in Penacony, restricting her outings under the guise of protection.
Orion pondered, although he knew Robin would be fine later, but…
If he let her go, Robin would have to beat up the protagonist group later, how could this simulation be like the game's plot?
I don't want to be run over by my sister and others on a train!
How much would that damage sibling affection!
What? A sis-con?
I am a sis-con, so what?
Must choose 2!
[You chose to "protect" her in Penacony. Villain Value + 50.]
At this moment, a thought formed with extreme clarity in your mind—
Must ensure your sister's absolute safety.
Forever.
You took a deep breath, and a gentle smile reappeared on your face.
"It's good that you're back safely, Robin."
You stepped forward, gently placing your hands on her shoulders, as if she were something fragile.
"The outside world is too dangerous."
"This time, you should rest well in Penacony, and the family will provide you with the best treatment."
"As for going out… we'll talk about it later."
You gazed at her, your voice incredibly gentle, but a nearly obsessive determination flickered deep in your eyes.
"With Brother here, you won't encounter any more danger."
From this moment on, you secretly made a resolution.
To transform Penacony into an absolutely safe "birdcage."
Impregnable, isolated from all storms.
And your most cherished Robin will forever sing safely under your protective wings.
Only for you, and your order.
