I Promised to Make the Class Honor Student My 'Little Sister'. It Seems She Wants to Be Spoiled a Lot - Volume 1 Chapter 4.1

The Classroom’s Beauty, Becoming My “Sister”

Previously…

Escaping from parents akin to an evil secret society who decide their child’s future on their own.

I, Takato Ryuuki, wandered the streets and was caught in a sudden downpour.

The ones who saved me were my classmate, Kakogawa Ao, and teacher, Kakogawa Yukari.

And with my resolve hardened not to return home…

──I made a “Family Contract” and became “family” with the two of them.

…Yeah.

I think it’s hard to understand what I’m saying, and I don’t really understand either.

But actually, I’ve been through such an unbelievable storyline.

Even more unbelievable is…

From now on, Kakogawa and I are going to try simulations to see which “relationship” is the best for us.

▲　◇　▼　◆

“Cough. So, are you two ready?”

In the Kakogawa family’s living room.

Sitting on a fluffy sofa.

Kakogawa Yukari-sensei, with her sharp, glasses-framed eyes, is looking at us with too much excitement.

Meanwhile, Kakogawa and I.

We’re standing face-to-face in front of such a sensei.

“Eh… Are we really doing this? Yukari-nee…”

“Of course, it’s a practice to become ‘family’. Don’t worry, Ao. I’m sure Takato-kun… can perform any abnormal ‘relationship’ perfectly!”

“Abnormal ‘relationship’…?”

With the audience of an overly enthusiastic sensei.

Our “relationship” challenge between me and Kakogawa──began.

Take 1: Kakogawa Ao【Younger Sister】　Takato Ryuuki【Big Brother】

“Big brother~ I’m so tired~ My shoulders hurt~ My legs hurt too~ Waaah… Give me a massage~”

“──!? Ka, Kakogawa’s acting is so real… Al, alright! Big brother will excitedly give you a massage~?”

“Yay, I love you~ …Ah, that feels good… Your hands are so warm… Fufuu”

──Just to clarify.

I’m not actually giving a massage.

Kakogawa and I are just doing an ad-lib exchange in front of Sensei… It’s an absurd improvisation.

So, it’s only natural that I’m a terrible actor.

Rather… it’s strange how good Kakogawa is at this.

“Let’s move on to the next one~”

And then, Sensei, who’s been enjoying the show.

──Irresponsibly directed us to take 2.

Take 2: Kakogawa Ao【Older Sister】　Takato Ryuuki【Younger Brother】

“…Hey, Ryuuki~ Go buy bread for your sister~, you punk~”

“Rough!? Is that a sister? Isn’t that just a delinquent?”

“Ah, was that wrong…? Ok, then… Hey, Ryuuki-kun? Do you have a girlfriend yet? If you don’t, should your big sister~… be your practice partner?”

“Bringing up inappropriate practices during a ‘relationship’ practice, what are you doing!? Is there no sister in Kakogawa’s mind but delinquents and shota lovers!?”

“Euuu… Yeah, you’re right… Sorry, so embarrassing…”

──Kakogawa, who had shown a pitiful performance this time, was quite different from take 1.

It seems like take 1 was just a fluke.

“Then, onto the next-”

Amidst this, Sensei──mercilessly proceeds to take 3.

Take 3: Kakogawa Ao【Mother】　Takato Ryuuki【Son (Baby)】

“Ah, um… What a cute baby~? I could just eat you up, you’re so adorable~?”

“Babu”

“Eh, what’s wrong? Are you… hungry~?”

“Babu”

“Oh, you’re hungry? Then, I’ll offer my breas──wait! That’s going too far, Takato-kun!! Pervert! Stupid!!”

“Wait!? I only said ‘Babu’! Why are you blaming me for your ad-lib going off the rails!?”

“I felt a lewd context in the second ‘Babu’!”

“No way! You’re reading too much into it!!”

“…Mu.”

After a fruitless argument, Kakogawa sat down on the spot.

Covering her generous chest with both hands, puffing her cheeks, and glaring up at me with puppy eyes.

…Isn’t that cheating?

Even in a situation where I’m absolutely blameless, it’s a tactic that puts the man at a disadvantage, right?

“I think the last one was the best fit for you two, don’t you?”

“Not at all! First of all, what’s with 【Son (Baby)】? It’s just us playing around, Sensei!!”

“Iーdisaーgreeー. I’m just helping until Ao’s image solidifies, this play… I mean, practice, is allーIーamーdoingー”

“Ugh… It’s just embarrassing, Yukari-nee…”

Thanks to the mischievous teacher, the “Sister” ends up being the most humiliated… Is this really okay?

Take 4: Kakogawa Ao【Sister】　Takato Ryuuki【Sister】

…Huh? I’m the “Sister”?

“Oh my, good day, Ryuuki-san. You’re slouching, you know?”

“Please overlook my posture… but isn’t that “sister” not like a family “sister”?”

“Is that so? Then, how should we do it? Can you, Ryuuki-kun, act like a “sister”?”

“Eh… Ohoohooho! Look, sister! I’ve bought a delicious-looking cake at the station!”

“…Yes, yes. Thank you for trying, Ryuuki-kun? You managed to sound like a girl! Yes, very girlish!”

“Thanks, Kakogawa. But really, you might as well just kill me now.”

I want to punch the me from a few seconds ago, seriously.

While I’m feeling utterly dismayed,

“──Hey, Ao. I’m in favor of adopting take 4.”

“Sensei. I’m seriously going to get angry now.”

I restrain the sensei, who just proposed something ridiculous, with a serious tone.

This person really acts without restraint inside the house… Though in a way, that’s “sister-like.”

Amidst this, Kakogawa──.

──tentatively raised her hand, looking hesitant.

“I, I’ve decided… the relationship between me and Takato-kun.”

Blushing furiously,

And fiddling with her bangs nervously,

Kakogawa said in a voice so small it was almost a whisper.

“I, I want to be the “Little Sister”, and Takato-kun to be the “Big Brother”… Please…”

Thus──based on Kakogawa’s declaration.

Sensei wrote the new “relationship” on the second page of the “Family Contract.”

Kakogawa Yukari…　【Elder Sister】Ao　【Younger Sister】Kizuna　【Twin】Ryuuki

Kakogawa Ao　…【Sister】Yukari　【Sister】Kizuna【Brother】Ryuuki

Kakogawa Kizuna…【Elder Sister】Yukari　【Elder Sister】Ao【】Ryuuki

Takato Ryuuki…【Twin】Yukari　【Sister】Ao【】Kizuna

“…Wait, Yukari-nee! What’s this!!”

“Hmm? I left the relationship with Kizuna and Ryuuki as pending. We need to hear Kizuna’s request too.”

“Not that! The relationship between Yukari-nee and Ryuuki──”Twin”!? Why is it already decided as “twin”!! Yukari-nee, aren’t you going to do that embarrassing thing too!?”

“I won’t, it’s embarrassing. Besides, I had decided on “twin” from the start.”

“It’s a loss, isn’t it, really! After going through all that, being seen by Takato-kun… Mooo~!, Mooー!!”

Are you a cow, maybe?

Such an incredibly inappropriate thought crossed my mind.

But considering how mad Kakogawa would get if I said that──I’ll keep quiet.
