- That's my secret.

Olivier Alway joined Jared Murphy in his room to hear all the secrets of his cousin Yennie Daum.

That they were afraid and forbidden to fight with the power of Yenny, who had no reason to fight or serve, while having the talent of a sword beyond their grandfather, Baron Daum, called the Sword Ghost. He seemed to have minimal training, but Olivier decides that this was because, as a swordsman, he thought somewhere that Baron Daum would be spared to make her abandon her talent.

Yennie's strength, however, seems to grow in talent with only a small amount of training, and her body will optimize her for battle if she has a sword. Olivier can't understand everything, but I just know that it's a force I don't want for a girl who doesn't need to fight.

Too strong Yennie was just a man of the Baron Dowm family of swords. He was also held hostage once because he was a weak girl, as my grandfather put it. Of course, he didn't think he'd be held hostage against Jared.

If you ask, he says it was also Yenny who saved Jared in distress and left Rosa Lowen of Vault Toyfel.

Jared, whom the girl admires as her brother, was chosen as the shackle of Yenny, who has all that power. Of course, sometimes my grandparents wanted Jared to be the head of the Baron Dowm family, but at the same time they were informed that it was for Yennie.

Olivier can't imagine exactly where so much strength is hidden in this cute little girl just by listening to her.

The only thing I can tell - Jared's becoming Olivier's fiancée has got Yennie involved again.

At least, if Jared and Yennie were engaged as planned, they could have been happy without the girl's secrets being revealed.

That makes Olivier feel guilty.

"Thank you for opening it up. I swear I won't tell your secret."

"No, sister. My grandparents told me to hide it as much as I could, but I don't really care. Besides, Rosa Lowen knows about it. Sooner or later, someone would have known about me."

"But..."

"I have something more important to tell you than that."

It blocks Olivier's voice, who is feeling the burden, and Yenny gives him a serious look.

"I wonder what?

I was ready to be complained about, and I was ready to be cursed to give Jared back.

"I couldn't tell you because I hid it when I saw you the other day, but I can tell you clearly today. I can help protect Olivier and Hannellone. I think we need more power than your brother, even if we still have the threat of Cornelia."

"... that's right, I mean?

"Please admit me to your brother's side room. I have the power I do not want, but with this power I will protect your family, Olivier. I will protect you, Olivier, not just your brother. So - accept me."

But what came out of Yenny's mouth was that he didn't want to be complaining or cursing, he wanted to be a sideroom.

It was the girl's upright thought that she wanted to be with Jared because she would use her powers to protect the Oliviers.

"I lost. To officially sideroom you, I have to officially speak to your grandfather and my father, but fine. I recognize you as a side chamber."

"- Sister!

"But! Not because I want to help you. Because I found out you thought of Jared all the way."

"Yes!"

Olivier also smiles when Yennie smiles happily.

To be honest, Olivier, who is not officially married, would not have the right to have a side room like this. But Olivier doesn't dislike Yennie, who has made his point without cowardice, because he has told the Jareds that the side room needs his permission face-to-face. Rather, I prefer it.

I even want to apprentice her for being young and, more importantly, cute and adorable that I don't have.

With some guilt in his chest, Olivier had no choice but to accept Yennie.

But I'm sure you'll do well, I'm unsubstantiated confident.

Olivier herself still needs to be ready to marry Jared. It will take a little longer to ensure that my mother's safety is not promised or that Jared is a minor.

But I think that's fine.

Olivier, who had never fallen in love in a long time, had just slowly walked away.

You should continue to annoy your fiancée, who is clumsy, dangerous, and has all sorts of secrets. And I guess I'll be made to worry about him and make him do it.

Until then, I miss living with my mother, Trane and the three of us.

Over time, Yennie will be living with us. And there's more to my house than that.

"It's going to be busy."

"... by the way, your brother doesn't move stiff?

"Leave me alone. I don't know what to look like when it lights up because you've decided to be a sideroom."

"Oh really? Also, if you're my brother!

It was Olivier who saw Jared stunned as he couldn't keep up with the unfolding while he was left behind and his grin spilled unexpectedly.
