My Multisystem In Isekai

But of course, the straightforward and incorrigible Nadia didn't even notice what was about to go down before she had so rudely interrupted. Indeed, it seemed like everyone else but Nadia was aware of the gravity of the crime she had committed. Nadia was feeling a lot of things in that moment, but shame and regret were definitely not among the list. In fact, she was actually jealous when she saw Zavier locked in a tight embrace with Shiranui. So, without even thinking, in the blink of an eye, Nadia impulsively rushed to the bed and pounced on Zavier.

It was a move that was designed to show Shiranui that she had sovereignty over Zavier and that she was nothing to her. Shiranui on the other hand completely lacked even the tiniest form of empathy. Her social intelligence was at an all-time low, so she couldn't discern the real truth behind what was happening here. Her instincts immediately kicked in like a shield, and she immediately reverted back to her cold self. It was almost as if she was incapable of any kind of human interaction at all.

The fact that Nadia was still just a family member seemed to have been lost on her. To Shiranui, she might have as well been another hostile. So, she shot her a cold look, and without saying a word, she got up and left the room rather quietly. Zavier wanted to move to escort her, but found himself in another fix altogether. He felt it wasn't intentional, put deep down, he knew it wasn't a mistake. Sitting on top of him on the bed, Nadia's ass was pressed firmly against his crotch!

Zavier was taken unawares! Due to the nature of how had left things with Shiranui, his rod was very hard from all the blood rushing to it. And without warning, Nadia had pounced on him, and pinned him down with her ass pressed up against his crotch! With every passing Nano second, Zavier increasingly felt that this was no mistake. It seemed Nadia was up to something.

Just as Zavier suspected, the next words that flew out of her mouth shocked him to the bone. Suddenly, Nadia ambushed Zavier with a very specific question;

"Come on Zavier! When are we going to get married!?"

Zavier nearly choked on his own tongue. He wondered if it was all the blood rushing from his head that was making him hear and feel things that weren't there. He was truly confused! Marry? How could she joke about something like this while sitting firmly with his cock pressed up so hard on her ass that it was dangerously close to her pussy?

"Marry?" Zavier stammered in confusion.

Nadia bounced against him in anger. "Oh no! You really forgot didn't you? Didn't you promise to marry me as your bride when I grow up?"

"Zavier!"

She smacked him playfully on his chin.

"You poor forgetful soul, you didn't really forget did you?"

Zavier had assumed that this was all some kind of joke, that Nadia was simply being her playful self. He thought that any moment now, she would burst into laughter upon seeing the expression on his face and laugh it all off as a joke. But as Zavier searched her eyes, he saw the opposite of casual jest, he saw hope. And that was all the push he needed. Immediately, he began to search out his own past memories.

His mind was like a giant cathedral filled with rows and rows of books representing multiple memories. Here, it wasn't just his own conscious memories from his past life, but the true memories of the person whose body he was inhabiting. Within the fraction of a nanosecond, Zavier whipped through the pages of these memories that weren't originally his, and found what he was looking for. It turned out that Nadia wasn't mad in the head like he had thought. After a quick flashback, he called to being the promise he had made to her in the past.

It had been so long ago. They were but children back then when he had promised Nadia that they would get married when they were grown. Zavier shuddered at the way it all seemed normal. Typically, this kind of marriages were regarded as barbaric. But here, it appeared to be the polar opposite. Not only were intra-clan marriages allowed, they were also very common. It was a widely practiced phenomenon that kept bloodlines pure, and free from external influences.

This whole thing had been birthed from the sheer hatred of peasant blood and outsiders. Because there were a lot of xenophobic noble families who cherished their own nobility and social standing more than their lives itself, this concept was quickly introduced. The first generation of medieval lords and aristocrat princes quickly discovered that they had a serious problem. There were a lot of family secrets, wealth, and an abundance of traditions that simply couldn't be trusted with outsiders.

So, they hatched the heinous plan of marrying each other's nieces. The children that followed married their cousins, thus eliminating the possibility of a stranger infringing on their family ties. This practice continued over many generations, making it commonplace among the pure bloods. The purity of the bloodline was vital. Especially in powerful and prominent families like the Adam family. Cousins taking a liking to each other was common. In fact, it was encouraged.

So, right from a young age, it wasn't odd to see cousins pining for each other. In some extreme cases, these cousins who found themselves trapped together in a big house (and with very little adult supervision) often ended up fondling each other in the dark, after lights out, under their sheets. These cases often made these cousins to grow up dependent on each other for the very air they breathed. From a young age, patterns are set, and by the time they were grown, an unbreakable bond would be formed. Thus, linking them for life.

While it reeked of incest to a stranger like Zavier, it was actually very common. This came as a bit of a shocker to Zavier for so many reasons. But mainly because in his mind, he had come to see Nadia as nothing but a sister. He appreciated her playfulness and the care she so often showered on him, but to a mature mind like Zavier, she was just a kid. The whole shift in dynamic had been so quick that he was still yet to follow up.

Zavier's brain was reeling. This was no joke, not to Nadia at least. He knew he had to think of something really fast, or else before he knew it, he would blink and suddenly find himself walking down the aisle with a new bride! The mere thought of it sent cold shivers down his spine. So, Zavier forced himself to hide his repulsion, and instead conjured another fake warm smile. He placed his hands on her waist and tried his best to sound optimistically hopeful;

"Is my sense of humor really that dull?! I was just joking Nadia, come on!"

He tickled her ribs and she burst out laughing in her high-pitched, loud cheerful voice. She continued to giggle as Zavier tickle her. She really loved to play- Zavier knew that now. It was a deliberate play to keep her in a good mood as he let her down easy with his next sentence;

"I can never forget my promise to marry you Nadia, I could never hope to marry someone else. You know that right?"

She nodded excitedly.

"But before that can happen, we both need to be at our best. And that includes a full education. We need to focus on our studies first okay?"

Zavier couldn't believe himself. He sounded like a parent.

"You're right!"she exclaimed passionately. "This is exactly why I want to be your bride Zavier, you're such a calm and forward thinker..."

Zavier was actively trying his best not to allow his face reflect his repulsion at the whole thing. It was truly cringe worthy. Of course he didn't approve of intra-clan breeding. He was a modern soul, and he understood the downsides to it. The genetic pool wouldn't exactly give room for growth. He wondered why the negative effects of consanguineous marriages in the physiological and genetical range hadn't been detected yet.

Naturally, Zavier kept these thoughts to himself. To voice them now would only increase his chances of being found out. So, wisely, he kept his reservations and disgust to himself. Nadia on the other hand continued to drone on;

"...on our wedding day, I'm going to be the prettiest girl in the whole world! You'll see! I have the perfect gown in my head, and all I need is a tailor to just..."

Kacie coughed and stepped forward purposefully, "That's enough for now Nadia..."

The older one had always been the more level headed of the two. Even now, she could see that Nadia was pestering Zavier like an annoying bee that just couldn't be thrown off. She had to step in to save Zavier, else, Nadia would most likely smolder him with her incessant ramblings.

Nonetheless, it was clear that Nadia wasn't too happy with Kacie's intrusion. She glared back at her defiantly, as if daring her to do her worst. Kacie didn't appreciate Nadia's rebellion. However, she understood. And because she did, she approached her logically;

"Nadia, surely you don't want Zavier to collapse from all the stress right?"

No answer.

"Well I'm sure you don't want that. So, let's give Zavier some time to deal okay?"

"But I-"
