Flowing brilliant silver hair with jewel-like sparkling eyes. Beautiful and mysterious face with all the parts perfectly arranged.

I can't go wrong. This child is Serenia Vlage. The Duke's sister.

"I knew you were my sister-in-law. How did you get here?

"Uh... uh..."

Angel-like beauty is approaching, and I'm stuck with it.

"Oh, when I was touring the castle, I lost my way with the samurai..."

I've been lying at a pretty low level. In the middle of the night, the bride talks about visiting the castle on her son-in-law's own, and who will believe it?

Master Serenia was pompous on my lies for a while, but eventually she gave me a soft grin that would envelop everything. And show the door behind you by hand.

"Then you must be tired. This is my room. Why don't we talk inside if you like?

"Yes..."

I should say no, but for some reason I nodded.

He leads me into Serenia-like room, but sits on a fluffy couch. And Master Serenia sat down in the chair across the street.

"Hehe. I've always wanted to talk to my sister-in-law."

Master Serenia smiles at her angelic beauty. That alone is going to make me wander.

Ugh, cute. Too cute.

Do such beautiful girls exist in this world? The Duke was pretty handsome with only his face, too. If the child is this, your parents must have been beautiful men and women, too.

—— Sure, although I heard he died in an accident eight years ago.

"I'm sorry, Master Serenia. It's annoying at this hour."

"I can't believe it's annoying. I'm rather so happy. And Serenia, please don't. We're family now, and you can call me Serenia."

"Heh? Well, Serenia...... honey"

"Yes."

When I call him by his name, he replies with a blur.

Does this child have the skills to master people's minds or something like that?

From now on my heart is a bakubaku saying-away. I'm going to hear anything Serenia has to say already.

"I thought this time was exactly what I was with my brother...... Could it be that my brother did something wrong?

"Yes, no. That's not true."

I do, but I shouldn't tell Serenia, so I'll keep my mouth shut. If you'll excuse me, I work for a lot of people in this castle.

"Me, I'm weak and I don't even show my face to the social world, so I don't have any friends close to my age. That's why I've been looking forward to having your sister-in-law. I was wondering if we could get along one day and stay up late chatting. I can't believe that's the dream come true so soon. Glad."

I've been waiting for such a pretty girl to talk about you, it's more impossible not to get up if she says so. My mouth burns when I stick to it.

... Well, it was the assassin who was actually waiting for me.

"Eh. The fact that Serenia has her room means that this is the central building of the castle..."

"Yes, this is the second floor of the central building"

Close to the master bedroom. Looks like he got into a dangerous area because he moved without thought. I can hide myself in Serenia's room for one second, but I have to travel vigilantly again.

... but this is also a good opportunity. I was able to contact the person closest to the Duke. It's a corner, so let's get some information about the Duke.

"Um, brother...... what is the Duke of Vlage like?

"Is that your brother? Phew."

Why are you laughing there?

"He's a very troublesome man. There's a lousy, uncomfortable, stubborn place, not very accommodating."

"That's..."

That's a real pain in the ass, I've been wanting to say. I am not without thought enough to speak ill of your brother towards your sister.

For the first time in my life, my sister-in-law, what a front of call, there are times when I wanted to make room for older people.

"But he's a very sweet man. I tend to be misunderstood because I'm always on the top of the Buddha. My brother has been by my side ever since my parents left the world eight years ago."

"... Serenia likes your brother."

"Yes!"

It was a quick answer.

Though I think I'm also relatively close to my brothers, "Do you like your brother? Even when they asked, I couldn't get my hair in." Yeah! "I can't answer that. I just imagine myself saying that I love my brother ♡ and I'm blinded.

I guess the fact that you can honestly say that you like your brother so much is a pretty deep bond between your siblings.

That rude and unfavorable Duke also looks sweet to you, sister. I'm sure you're so rude and ruthless to others because you've put too much love into your sister.

Thinking about it, my breasts filled with remorse again.

You're a sweet brother to my sister, why did you disparage me?

I wish only a fraction of the kindness for my sister would have split it.

"My brother took over the title at the age of 12, and then he has carried a lot of heavy duty on his own. It really should have been hard, but I've never had a weak sound in front of me about how good it looks to my sister.... So I was really relieved to hear that my brother was getting married. My brother gradually showed up with a woman he wanted to walk with."

There's so much mistake that I can't laugh and listen to it flow from Serenia's mouth.

A woman who wants to walk with you? Instead of walking with me, I'm being ignored and dashed, and I'm eating leftovers. And I, too, am currently admirably dashing in the opposite direction from the Duke.

I don't want to strongly deny what Serenia has to say, but at least I have to figure out the misunderstandings.

"No...... The Duke doesn't seem committed to the person he marries. Looks like you just picked the right one for me. It is very, very important for me to support the Duke..."

"... who told you that?

The look on Serenia's face suddenly makes her pin cold.

Could he be angry? I rushed to say it, but when I was stared into my eyes like a sapphire, the words of deception stopped coming out, too.

In the end, I'll have to answer honestly.

"... I heard the Duke talking like that."

"When?

"Between Today's Parties"

……

Serenia shut up and awkward silence ensued.

This kid must be the scary type to piss him off. It's called Harriet the Samurai, I'm vulnerable to people like this, who can speak only of the air.

"... sister-in-law"

"Yes?

"Let's go to my brother now. You have to ask me."

"Eh."

To the Duke? You mean in the master bedroom?

That's not good.

That master bedroom is dangerous. If the killer were a duke, he wouldn't even reach Serenia on the boulder, but I'd have a high chance of getting a bump stab.

I can't afford to be on the Duke right now in the first place. I want to leave this mansion quickly.

"Wouldn't that be tomorrow? It's late."

"I can't wait till morning."

It's surprisingly short-lived. I find it hard to argue with them when they say it out loud.

"Uh... the Duke may be off already"

"I'll beat you up"

"... annoying."

"It's a family thing. No need to shy away."

Ugh. Serenia, she's got a pretty face and a pretty system.

Speaking of which, during the day, this kid got rid of the Counts of Rosner. Maybe this makes me feel surprisingly strong.

"Actually, I went to the master bedroom once, and the Duke wasn't here. So I don't know where he is, and I think we should reschedule him."

"I wasn't in my room...?

Please give up on this.

Pray inside, before Serenia, who thinks a little silently.

But again, Serenia shook her head.

"I know where my brother seems to be. Now, let's go."
