I Promised to Make the Class Honor Student My 'Little Sister'. It Seems She Wants to Be Spoiled a Lot - Volume 1 Chapter 7.1

Me, Returning Home, Achieving First Contact with a “Family”

On Friday, I left home.

On Saturday, we formed a “Family Contract.”

On Sunday, I was spoiled by the “Little Sister.”

And by Monday, somehow one of the “Twins” became our homeroom teacher.

“…In just four days, too many things have happened.”

As I swayed in the train, I reflected on these intensely packed four days.

The surprise of getting a new class homeroom teacher—this morning’s first thing—from my “Twin,” Yukari.

When I discreetly spoke to her during the break, as expected, she said, “I wanted to surprise you, so I kept it a secret☆”. I kind of figured as much.

Please, no more surprises today… But with Ao and Yukari, who knows what might happen next.

“──Next stop is Nanakuro Station, Nanakuro Station.”

Hearing the train announcement, I hurriedly stood up.

That was close. If I’d spaced out any longer, I would’ve missed my stop…

The nearest station to the Kakogawa’s is one stop before my old home’s, so if I’m not careful, I might end up going too far. I need to pay attention.

Thinking such, I exit the station closest to the Kakogawa’s and head straight home without any detours.

According to Chitose, my belongings are supposed to arrive shortly. I need to get back quickly to receive them.

As for Ao─she’s still at school due to a friend asking for advice.

And Yukari─apparently has a staff meeting that will take a bit longer to finish.

So, for now, I’ve been entrusted with a spare key to their home.

“…Even though we’ve become ‘family,’ holding the key to a girl’s house makes me feel like I’m doing something wrong, even though I haven’t.”

Well, it’s probably not something to worry about.

Just need to receive the packages and then go back to my room to wait for the two of them to return.

After all, with the two girls not around, there’s no chance for any dubious events to occur.

But still… Just the thought of holding a girl’s house key makes me a bit nervous.

This is, you know─the complexity of a guy’s heart. Probably.

“…Ah”

As I arrive at the house,

A delivery person is just getting off their truck and is about to ring the Kakogawa’s doorbell.

I call out to the delivery person and unlock the front door.

Then, after bringing several cardboard boxes inside and paying the delivery fees─I finish receiving the packages.

“Ah, shoot… I should have asked them to carry it upstairs.”

After the delivery person leaves, I realize this too late.

But it’s too late now. I have to carry them up myself.

Sighing at my oversight… I reached for the cardboard boxes.

─That was when it happened.

“─Ao-neechan. Do you know where the extra shampoo is?”

“Huh?”

The door to the washroom bursts open,

And an unfamiliar girl leans out.

─In nothing but a bath towel wrapped around her body.

“…Huh? Ao-neechan isn’t… Wait, who are you?”

“Uh, well… it’s a long story, but…”

“─Wait! No, Yikes!!”

Before I could say anything else, she─realizing her compromising attire─

Clasped the bath towel with both hands and retreated back into the washroom.

Then─peeking out just her head, she glared at me through the gaps in her damp hair.

“Don’t look here!! You pervert! Lolicon!”

“Wait, wait! You’ve got it all wrong!! I can explain, really!”

“Like I’d believe that! Some peeping Tom breaking in… I’m definitely calling the cops on you!”

Tragic news.

I, who had run away from home, was about to be apprehended for suspicion of being a molester────.

“Hahahahah! That sure was unfortunate, Kii-chan?”

“Don’t call me Kii-chan! And don’t laugh!! Do you realize a peeping Tom has seen your ‘little sister’ naked!?”

“Come on, Kizuna, calm down, okay? Geez, Yukari-neechan! Stop teasing Kizuna, will you?”

“…”

Because I had stumbled upon the mystery girl who was apparently taking a bath, I was on the verge of being reported to the police.

However, thanks to Ao, who returned a little later, diffusing the situation, I miraculously avoided a police matter.

After Yukari came home, the four of us gathered in the living room.

This is how we began to sort out the situation─that’s the deal.

“Anyway, Ryuuki-kun didn’t intentionally peep on Kizuna. It was just bad timing. Plus… It was our fault for not telling Kizuna about Ryuuki-kun. Sorry.”

“…Yeah, seriously. If I knew some unknown guy was in the house, I wouldn’t have taken a bath.”

Murmuring her grievances, she lazily lifted her hair.

─Her ash-gray long hair reaching down to her waist.

A petite frame and a small face.

Yet, her eyes were large and round, like those of a French doll.

But her outfit, boldly exposing her shoulders and a leather mini-skirt, along with perfectly done makeup… made “a delinquent French doll” a more accurate description.

She is─the last “family member,” Kakogawa Kizuna.

Ao’s real younger sister, about to be a third-year middle schooler.

Since the day I ran away and was taken in by Ao─Kizuna-chan had been on a three-night, four-day school trip.

And today, midday, she returned home.

Thinking to wash off the sweat, she went to take a bath─unfortunately, at the same time I came home.

Not knowing that I had started living with them, hearing noises, she mistook it for Ao coming home and stepped out of the bathroom in just a bath towel.

Resulting… in that unpleasant incident.

“…Hey. Don’t look at me with those lecherous eyes, will you?”

Kizuna-chan said coldly, covering her chest with her arms.

Her round eyes glaring at me accusingly.

Then, even Ao… started looking at me with suspicion.

“…Ryuuki-kun, do you like girls like Kizuna?”

“Wait, wait! Did I even utter a single word? This is another false accusation, following the molester one!?”

“Exactly. Whether Ryuuki’s type is like Kizuna or not, doesn’t matter. After all, male high school students… they’ll look at any girl with lecherous eyes! That’s just what they are!!”

“Yukari, wanna keep quiet? I’ll sue on behalf of all male high school students. For defamation.”

See what I mean?

Ao is giving me those looks.

And Kizuna-chan, she even started covering her exposed shoulders with her hands.

I really wish she wouldn’t stir things up unnecessarily. Even if… it wasn’t wrong about the ecosystem of male high school students.

“…This sucks. What even is this situation?”

Kizuna-chan grumbled,

Hugging a nearby cushion, covering her shoulders… and said languidly.

“Takato Ryuuki, was it? Why the heck did a complete stranger like you sign a “Family Contract”? Doesn’t make any sense, right?”

“Well, that’s… as Ao explained earlier. I have my reasons for not wanting to return home, and to give me shelter, parental consent was required. As a preliminary step to that─we signed the “Family Contract.”

“No. That’s what I’m saying makes no sense.”

With a prickly reply,

Kizuna-chan started reading the “Family Contract” revision she held.

“…Ao-neechan’s “brother” and Yukari-neechan’s “twin”… What’s this about? “Twins”? What does that even mean? Makes no sense.”

I wish you’d ask the proposer, Yukari, about that.

“Well, for now… it’s good that the “Relationship” section for me was left blank. If something was written there without my consent, I would have been the one running away.”

“That’s why I thought we’d hear what you prefer. “Brother─Sister” “Father─Daughter”… The “Relationship” can be anything, right?”

“I’m saying I don’t want it.”

Kizuna-chan sharply retorted Yukari’s carefree attitude,

Lazily lifting her hair and stood up.

“A stranger’s “Family Contract” is just super weird. My family is─just Ao-neechan and Yukari-neechan. Only the two of them… are enough.”

“Wait a sec, Kii-chan.”

“Don’t call me Kii-chan! I… don’t care anymore.”

“Hey, Kizuna, wait!”

Then, Kizuna-chan, ignoring Yukari and the rest’s attempts to stop her, left the living room.

Stomping loudly─she went upstairs.

“She’s really unfriendly, huh… Sorry, Ryuuki-kun? My sister was rude.”

“No. If anything, I should be the one apologizing.”

After all, a sensitive girl was seen in a compromising situation by a stranger.

It’s understandable her anger hasn’t subsided.

And about the “Family Contract”… what she’s saying makes perfect sense.

Becoming “family” with someone you have no blood relation to.

It’s natural to have resistance to that…
