12-sai.: Chicchana Mune no Tokimeki (12歳。～ちっちゃなムネのトキメキ～)

12 years old.

It's a weird age when you aren't a child or an adult.

When your body and heart changes.

We are lost at the cusp of puberty and on the path of becoming an adult.

My ideal kiss?

My older sister kissed her boyfriend yesterday!

Wow.

Hey Yui, how would you like to kiss someone?

Kiss...

I haven't really thought about that.

Here, here!

I want to be with Sakurada on the way home from a date at the amusement park!

Where he pushes me against the wall and stares into my eyes with such passion...

Hanabi, Sakurada is an idol, right?

It'll be difficult to get to know him.

It'll all work out somehow!

Ayase, you too?

Takao!?

You say such girlish things, too?

Girlish? I am a girl!

Look! I'm a girl no matter how you see it!

I want to fall in love, but boys lack any sense of tact!

Having a boyfriend still sounds a bit embarrassing...

Ayase Hanabi, age 12.

"Kiss, Dislike, Kiss"

We are finally 6th graders!

Our last year in elementary school.

What's wrong, Hanabi?

Why does he always make fun of me?

I talked to my parents about you yesterday!

Oh, you talking about Takao?

He's perfect at sports and studies! So cool!

Currently the most popular among the girls!

Is he that cool?

You don't think so, Hanabi?

Nope!

I can't really tell what he's thinking about.

Pink polka dots!

Eikou! Stop flipping girls' skirts!

Hiyama!

Yui!

I'm the best!

Hiyama! Stop telling the boys to do weird things!

Huh?

I can't believe you're telling them to flip skirts!

Aoi, I never told them to do such a thing.

I just said that when our parents were young,

boys who flipped skirts were heroes.

That's so cool!

Pink polka dots!

You're the one egging them on!

Stop your yapping.

I'll flip your skirt too, Aoi!

Hmph! I'm wearing shorts today.

I don't want to see your panties anyway.

What did you say!?

Let's go, Yui!

Okay!

Aoi looks so mature!

Huh?

You keep getting scolded by her. How nice!

Let's go flip her skirt the next time she wears one!

Okay?

Sorry!

Why are the boys so childish?

Aoi.

What?

Don't you ever wear skirts again!

What is he talking about?

I have Class 6-2's girls' popularity contest results!

Popularity contest? The boys sure are bored.

How mean!

Eikou's number one is...

Hamana Cocoa!

She's number one!

I'm so embarrassed!

Did you vote for me, Takao?

No, I didn't vote.

There you go again.

And here's last place!

The girl who isn't popular at all is...

You're going that far?

Ew!

Stop it!

Huh?

You're making everyone uncomfortable!

Mind your own business, Ayase!

Stop it! Just stop!

Takao! What are you doing!?

The teacher's here.

What are you guys doing!?

Oh no!

Why is our class the only one where the boys and girls don't get along?

Well, even if you ask us...

It's because we're different!

I've decided.

I told you all that there will be a recorder test next week.

You will take the test with the person sitting next to you.

Eh!?

Please practice as a pair.

We're pairing up with the person right next to us...

What?

I'll never pair up with a girl!

Me neither!

Teacher! I want to be with Takao!

You can't be picky.

Get along with the person sitting next to you.

Let's do this, Ayase.

Okay!

I'm with Takao? I'm a bit nervous.

Open your eyes, old lady.

I'm the only one who can be with Takao.

Hey, Hanabi, you understand, right?

Huh?

Takao's only treating you nice because he's sitting next to you.

Don't you dare ask him out.

Sure.

I'm not interested in boys.

Really? Thank you!

Your hair is so smooth and cute!

I'm sure you'll get a boyfriend someday!

Boyfriend? I don't really understand.

Hanabi.

Yui?

What should I do?

Here you go.

I'm sorry about this.

Aoi, when a girl gets her first period,

that means her body is getting ready to become a woman.

It's something to be happy about.

There's no need to be embarrassed.

What should I do?

Huh?

I don't have a mom...

Talking to my dad about this is embarrassing after all.

But I don't think the pad the nurse gave me is going to last long.

I'm scared to buy more by myself!

Let's go!

We'll go buy some together!

Really?

Yeah!

There are so many types!

Ones for daily use, for heavy days, and ones on sale!

Okay! Let's go for the ones on sale!

Do your best, Yui!

You did it!

Welcome!

A woman came to help the young guy at the register!

Now's our chance! Let's break through here!

Okay!

Okay! To the register!

Oh, that's so cheap!

Don't worry about me!

Use this opportunity to break free!

Hanabi!

Thank you very much!

Somehow we bought it.

It's all because you were with me.

I'm heading this way.

Okay.

Then see you tomorrow.

Be careful on your way home.

Yui's becoming an adult.

But I'm not that far yet.

I wonder when my period will come?

I'm not pretty and I don't understand love at all.

I'm so childish. Will I ever become an adult?

That's a unique sound.

You don't need to be so considerate.

Then you suck pretty badly.

You didn't have to go that far!

You have it so nice, Takao. You play so well.

I'm pretty bad at the recorder.

But you're practicing a lot to make it sound perfect, right?

Of course!

That's who you are, Ayase.

You should practice too, Hiyama.

Don't wanna.

If you don't want to then I'm going home.

You really hate pairing up with me that much?

How did things turn out like this? What a brat.

Did you hear that? I played one part perfectly!

You weren't listening at all!

Hey, Takao! What are you looking-

Oh, it's our teacher!

She's with the teacher from next door?

They've started going out.

Really? I never knew!

I wonder if they can hear us?

Teacher!

Did they just kiss?

Sorry.

Let's go home.

Okay.

Ayase Hanabi, age 12.

I just had my first kiss.

Well, our eyes just met by coincidence...

We got caught up in the mood!

That's so lewd!

Too lewd, Hanabi!
