Betraying My Perfect and Beautiful Childhood Fiancée, I Fell in Love With My Devilish and Naughty Older Sister - Chapter 3 - Jealousy

Chapter 3 – Jealousy

That being said, I didn’t know any beautiful foreign-looking girls like her. Well, there’s Aika, but…

That Aika is clinging to my arm and she whispered in my ear,

“Chiharu-san is a senior in her third year of high school.”

“Do you know each other?”

“Yes, only a bit.”

Aika’s words were vague. The perfect beauty Aika is basically kind to everyone.

That’s why I was a little surprised to see that Aika had a very unfriendly expression on her face towards the senior named Chiharu Maria.

Speaking of Chiharu-senpai, she was smiling.

Her first mysterious expression was stunning, but her bright, lively smile was even more attractive.

“Amahashi-san. Don’t look so scared. It’s okay to come and see your sibling, isn’t it?”

Sibling?

Who with whom? Aika only has two younger sisters from her father’s marriage with his second wife.

But I’ve never heard of Aika having an older sister.

Aika tried to speak, but—

Chiharu-senpai interrupted Aika’s words.

“I thought I’d be allowed to say hello to my brother, whom I’m meeting for the first time.” 

“B-Brother…?”

“Yes. I—Chiharu Maria—will be your sister.”

Chiharu-senpai said this as if it was a matter of course.

I couldn’t understand Chiharu-senpai’s words. Aika, on the other hand, was looking pale for some reason.

“In other words, I will be adopted by the Hashiro family. I’m going to be Hashiro Hayato-kun’s stepsibling.”

Chiharu-senpai went ahead and explained as if to answer my inner question.

“My father adopted a daughter…?”

“It’s not uncommon, especially in the Five Seasons Households, right?”

The Five Seasons Households are five families that occupy a special position in the Japanese government and business world.

In the year 2028, after Tokyo suffered catastrophic damage due to a celestial collision known as the ‘Great Luminary Catastrophe,’ the government relocated Japan’s capital to Nagoya.

Twenty years later, Japan is a different country from what it was before.

The value of life became lighter, and unreasonable deaths had become the norm. The gap between rich and poor widened and the country fell into third class status. The country’s security situation deteriorated markedly.

One of the countermeasures to this situation was the revival of the pre-World War II noble family system—In other words, aristocracy.

The five prominent families that played a significant role in post-disaster reconstruction became marquises and are collectively referred to as the “Five Seasons Households.”

Honno, Denpoin, Nishimikura, Amahashi and Hashiro. It is even said that these five households constitute the backbone of New Japan.

Thanks to this, the new city of Nagoya, surrounded by walls, is absolutely safe and protected.

That said, the Chiharu family is not one of those prestigious families. I think I’ve heard about it somewhere, and there’s something about it that sticks in my memory, but I know in my head that it’s not a prominent family.

Taking in an adopted daughter holds significant connotations of being used as a pawn in political marriages. The adopted daughter is expected to come from a family of decent status—a viscount family, baron family, or a family with a respectable name even if lacking a title of nobility.

When I think about it, I hate myself for being thoroughly imbued with the Hashiro family’s way of doing things. 

We will get what we want by any means necessary. Regardless of whether that means using a living human being or a teenage girl.

That’s the Hashiro way.

In my heart, I wondered if this girl, Chiharu Maria, would be of any use to the Hashiro family.

Chiharu-senpai looked into my eyes, unaware—or pretending not to be aware—of my inner thoughts.

“So, from today onwards, please take care of me, Little Brother♪”

“Little Brother… It’s a bit embarrassing to be called that…”

“You’re dissatisfied? Then you can call me ‘Onee-chan’ too♪”

Chiharu-senpai said teasingly. Then, she brushed back her red hair.

The gesture was so beautiful, I couldn’t help but be taken aback.

Unfortunately, Aika noticed it.

“Ha, ya, to, kun?”

I looked at Aika, and she was staring at me with a jealous look in her eyes. Aika is basically a kind person, but at times like this, she reveals her jealousy.

I guess it means that she likes me enough to get jealous easily…

Fufu, Chiharu-senpai laughed.

“You seem happy. I hope it stays that way forever.”

“Huh?”

“It’s nothing. Well, I don’t want to interrupt your date with your fiance, and we’ll have plenty of time to talk later. Well then, see you later. Little Brother.”

Saying that, she waved her hand lightly and Chiharu-senpai disappeared.
