Engaged to the Unidentified (未確認で進行形)

Where am I?

What am I doing here?

So warm...

That was a strange dream.

I'm Yonomori Kobeni, and today is my sixteenth birthday.

Nothing special is happening just because I'm turning sixteen,

but just turning sixteen feels special by itself.

Okay!

It's important to start off on the right foot.

Be sure to make yourself look good.

It's the age when girls can get married, so it makes me feel a little grown-up.

Engaged to the Unidentified

Good morning!

Kobeni!

Sister!

C'mon! Hurry, hurry!

Happy Birthday Kobeni

Happy Birthday!

Here! Do it in one breath!

First thing in the morning?!

Kobeni, is it good?

#01 It's Important to Start Off on the Right Foot

Is it good?

So you're sixteen now, huh? Time sure does fly.

Yonomori Benio

Thank you, Sister!

I'll do my best to become an amazing woman like you in the future.

How? How could you have grown up so adorable?!

Sister! Sister!

You're awfully noisy first thing in the morning, Benio.

Good morning, Mother.

Honestly, it's your fault Kobeni talks the way she does.

Yonomori Akane

Isn't it adorable?

Well, it's better than her being foulmouthed, I suppose...

It's fine 'cause it's adorable!

But I can't say I'd mind being called "Dear Sister," "Sister Mine," or "Sissie," either.

Happy Birthday, Kobeni.

Thank you, Mother.

There's something I need to tell you.

Yes?

We'll be taking care of an acquaintance of your grandpa's, starting today.

Starting today?

Actually...

He's been here this whole time.

I didn't notice him at all!

This is Mitsumine Hakuya-kun.

We're taking care of... a man?

Incidentally, your grandpa picked him to be your fiancé.

What?!

What are you talking about?!

You met him when you were little. Don't you remember?

Not at all!

But an arranged marriage in this day and age? Why?

The countryside lacks suitable brides.

That's an overly realistic description!

Sister, did—

You knew about this?!

Grandpa decided it, so there was nothing I could do.

If it were my choice, I would have raised you myself,

through high school, college, adulthood, job hunting, middle age,

your 60s, your 80s, your 90s... You would have never left this house!

I don't want that!

Well, it's not like anything has to happen right away.

Take your time and think it over.

But still...

Do you have a boyfriend already?

N-No, it isn't that.

But why does it have to be me?

Sister's a girl, too.

Benio is fine at a glance, but you know how her personality is.

And she is the oldest...

You're not denying that, Kobeni?

There's a reason why it has to be you, anyway.

Hey, you.

You've been spacing out all this time. Are you okay with this?

You're betrothed to my beloved little sister.

Are you truly aware of that?

I grew up with everyone around me saying it, so...

You're just doing it because everyone told you to?!

Anyway, I'm against this!

Then again, someone else made this decision for him, too.

Maybe I was being rude.

Yes, yes, yes!

Who is—

Are you Yonomori Kobeni?

Yes, I am...

You're shorter than I expected.

I am Mashiro. Mitsumine Mashiro. Hakuya's little sister.

In other words, your sister-in-law.

I was worried about letting my space-case brother loose in the city alone,

so I opted to join your family, too.

A pleasure to make your acquaintance.

Wh-What's going on here?

Well, taking care of two is no harder than one.

Mother! No...

But what are we going to do about rooms and beds?

Really, what am I going to do?

A little girl! A little girl! What do I do, Kobeni?

It's a little girl!

Please stop saying "little girl."

Delicious! So this is what cake is?

You've never eaten it before?

Well, we live in the mountains, after all.

A really popular pâtissier made that cake for us.

I know! Why don't we all go to the bakery and eat it together sometime?

The invitation is greatly appreciated.

However, I cannot continue to impose in this fashion.

I should like to repay this debt next time.

What is the person's name? Pâtissier what?

She's acting mature!

It's a little girl trying to act mature, Kobeni!

I told you, stop saying "little girl"!

What? Have I said something incorrect?

Why did you give me milk instead of tea?

Are you looking down on me because I'm a child?

I just thought it would be better than tea or coffee.

You don't like it?

No, it's my favorite!

She just wants to play "sister-in-law," I bet!

glug glug glug

Anyway!

I shall make you a suitable bride for the Mitsumine household.

I intend to be relentless with you, so please make yourself ready!

Umm...

Well, I've got a few things to say myself!

I'm the one giving up my super, super, super adorable Kobeni to marriage,

but he's been shockingly imperceptible this whole time! Is he really okay?

He was born that way. Just let it go.

I can't let it go! How can you...

What? What? What's going on?

All this about a fiancé and a sister-in-law all of a sudden...

And what's this "suitable bride" stuff?!

And Mother just blithely accepts the decision.

I'm the one who does the cooking in this house!

I don't have enough to feed two people turning up unannounced!

Kobeni blew her top!

I'm going out!

But we're not finished!

I don't have enough to feed everyone! I need to go out shopping!

Oh, maybe she's not that mad after all?

Honestly. The menu I've been planning out for the week is completely down the drain.

I mean, this is all just so sudde—

What?! When did you...?

It's dangerous to go by yourself.

You are very important, Kobeni, so I must protect you.

Wh-Where did that come from?!

B-Besides, there's nothing dangerous about shopping.

But you were about to fall.

W-Well... Thanks for that.

But still!

I can carry bags, too.

I can carry bags by myse—

Actually, we are running pretty low...

Detergent

Soy Sauce

Rice

Okay. I guess you can carry some bags.

Still, I have no idea what he's thinking.

To suddenly say, "You are very important,"

and call me by my first name like it's nothing...

This guy might be a real smooth operator.

Or maybe he's not smooth at all.

Um, is it true that we met a long time ago?

We played together.

I see. I don't remember it...

I had an accident when I was little.

I don't remember anything that happened before then.

I'm sorry.

What?!

I just... felt like doing that.

Seriously, what's with you?!

You can use this room.

It was actually Grandpa's room, but...

Thank you!

If anything isn't to your liking, just let me know.

Sorry to disappoint, but we're scrupulous about cleaning,

my tiny sister-in-law.

Mashiro-tan, don't tease my sweet little Kobeni so much, okay?

Tease her? I'm not that mean.

If you do...

Then I'll have to tease you, Mashiro-tan.

She's serious?!

It's okay! Kobeni is the cutest in the world to me,

but I love little girls, too!

We're back!

This is not okay! Hakuya!

Don't be afraid. Come here, now.

What are you doing, Sister?

Welcome back, Kobeni.

Huh? What happened to your face?

Domestic violence already?!

I'm sorry I hit him like that.

He said something that weirded me out.

Hakuya isn't good with words, so he's very straightforward.

He tends to give the wrong impression because of it.
