The best parts of the day passed for Deon without the need to leave his room—just training, resting, and learning. Yven was a great help in this easy routine, as she took care of his basic needs like food.

Deon had grown fond of the young girl, and his admiration only deepened when he tasted the improved version of coffee with Milk she had prepared. It was heavenly.

Though Deon had never liked the idea of having a personal servant before—something that went against the instincts he had developed in his previous world—he now had no complaints. Yven, despite being a bit clumsy, was extremely helpful.

She might lack the experience of a seasoned servant, but Deon would still choose her over anyone else for simple reasons.

She listens without overstepping his instructions.

She only acts on what she deems appropriate, without prying into Deon's personal affairs or exceeding his orders.

She carries a sense of innocence—a quality Deon appreciated.

These were just the positives stemming from her personality, not to mention her connection to Viktoria de Avila and the knowledge she might possess.

She was simply perfect in both heart and form.

Deon’s current break ended once he had replenished the mana he lost in his earlier training, and now he was ready to continue.

He closed the book he was reading without marking his place—mainly because he could now recall even the smallest details, such as page numbers or stopping points.

Deon's memory had grown incredibly sharp and capable of recalling past events with great clarity. He had even recovered some childhood memories that should have faded with time.

He rose from his seat at the desk in his room and returned to the bed, where the blue cube rested. Its surface bore a mixture of intricate blue and black patterns, though the black still outweighed the blue. Deon's progress, however, was steadily accelerating.

Sitting cross-legged on the bed, he prepared to resume his training. He closed his eyes... but the peace he anticipated was disrupted by the sound of the door bursting open.

“Missed me, baby brother?”

Deon opened his eyes again to find Vierenna approaching him with a wide smile.

But something about her felt different.

Ignoring her silly grin, she exuded the air of a true noble—especially with the outfit she wore.

Vierenna was dressed in a refined yet practical ensemble. A crisp white blouse adorned with fine embroidery near the collar. A high-waisted navy skirt, cinched with a meticulously decorated belt. Transparent stockings with intricate patterns, adding a touch of elegance and allure.

Draped over her shoulders was a dark blue cloak resembling a coat, its edges embroidered with faintly glowing symbols.

She also carried a small bag featuring the emblem of the Eirenios Household, as Deon had learned in his recent studies.

Deon suddenly grew curious about why his sister would dress like this and where she had been during the last day and most of today.

Previously, he had assumed her absence was related to the Memories Record book, but that now seemed far from the truth.

Deon set the cube aside when Vierenna sat on the bed across from him without even asking.

“So, how do I look?”

‘Oh no!’

Deon wasn’t going to compliment her appearance, just to avoid dealing with her wordplay and hidden meanings. But she saw through him and went straight to the question.

“You were born beautiful, so what’s the difference now? You’ll always be beautiful.”

This was Deon’s answer to the loaded question, hoping she would accept it without further complications.

Vierenna rolled her eyes and crossed her arms.

“Fine, fine. I’ve been mean to you before, and now you’re cautious. But I don’t like it when you’re not honest.”

“In that case, you look as beautiful as moonlight piercing through the clouds.”

Vierenna raised an eyebrow, leaning forward slightly in contemplation.

Deon thought she was about to say something, but she fell silent as her gaze landed on the cube beside him.

She moved a little closer to Deon and picked up the blue cube in her hands. Her expression shifted to a slight frown as she ran her finger across the blue patterns on its surface.

Her eyes met Deon’s, who watched her curiously.

“You surprise me, baby brother,” she said.

“Don’t move; let me examine you a bit.”

She placed her fingers on Deon’s chest. He remained silent, watching her with curiosity. He knew Vierenna wouldn’t do anything to harm him.

A faint white light emanated from her hand and entered Deon’s body. He felt an addictive comfort that relaxed every muscle in his body.

He almost fell backward, but Vierenna caught him with her free hand at his waist.

A few seconds later, she withdrew her fingers, and Deon returned to his usual calm state, albeit with lingering embarrassment.

“Wow, I don’t know what to say!”

Deon tilted his head slightly, still silent.

“Well, it’s clear you’re a genius for your achievement with the cube. But that’s only dependent on mental state, understanding, and adaptability if you feel to add it. To progress this quickly, though—that’s just cheating. I’ve never seen anything like it.”

She was mere centimeters away from Deon’s face, her gaze scrutinizing.

Deon’s eyes twitched slightly, more from embarrassment than tension.

“If you continue like this, you’ll reach the minimum threshold for learning a beginner-level spell in about three days.”

This was good news for Deon. Knowing his training was yielding results gave him a sense of accomplishment. Still, he didn’t let it get to his head.

Soon, he refocused on Vierenna, who continued to watch him with curiosity.

“So, are you here for the Memories Record?” Deon asked, trying to discern the reason for her absence.

“Did you feel lonely without me, baby brother? Well, I can’t blame you for that, I suppose.”

Deon’s expression remained neutral. He wasn’t going to give her what she wanted.

“You’re no fun.”

“If it helps, I’m happy to be boring.”

Vierenna flashed a dazzling smile, quickly extending her hand toward Deon’s face. He wasn’t prepared and couldn’t avoid her.

“Is this how you treat your wonderful sister? You need to learn a lesson.”

Deon tried to resist, but Vierenna adjusted her position to restrain both his hands.

Deon’s expression sank, and in his helplessness, he stopped resisting.

“I’m sorry, wonderful sis. I won’t disrespect you again.”

‘She’s so hard to deal with.’

Vierenna beamed brightly, still holding him in her grip.

“Apology accepted, but I’m still going to teach you a lesson. It’s my duty as your elder sister.”

She released his hands and began tugging at his cheeks. It wasn’t as painful as it seemed, so Deon only put up minimal resistance. He certainly didn’t want to ruin the good mood Vierenna seemed to be having. Who knew what she might do?

After a few seconds, she let him go, and Deon exaggeratedly rubbed his cheeks.

“I’m satisfied now. See? That wasn’t so hard.”

When Deon didn’t respond, So Vierenna finally decided to answer his earlier question.

“Actually, I’m here for another reason.”
