Yandere Imouto ni Aisaresugite Kozukuri Kankin Seikatsu - Chapter 13 – Assumption

Tomaro and I left the coffee shop after a few minutes of talking about school-related stuff.

I told Tomaro to go straight home, and we parted ways. What should I do now?

I checked the time; it was half-past five. Even if I went home, mum wouldn’t have made dinner yet, so I guess I’d kill some time for now.

As I was wandered aimlessly, I passed by a park, and a familiar face stopped me in my tracks.

“A frilled skirt blowing in the wind and a black gothic dress?”  Oh, it’s Ayaka.

“Ayaka… …”

“Are you going home?”

“Yeah.”

“Let’s talk a bit then,” she said as we walked towards the bench.

Looking at her from behind, I wouldn’t have thought that we were the same age. She was so thin that one would assume that she’s malnourished. It won’t be an overstatement to say that she was as short as a grade-schooler.

“Where’s your little sister?”

Ayaka asked as I sat beside her.

I replied to her with a forced smile.

“Being brother and sister doesn’t mean we’re together all the time.”

“……”

She was poker-faced. I wasn’t sure if she was listening to me or not, but then she started talking.

“Are you two really siblings?”

“You’re asking me?”

“Yeah”

“We are. We’re not blood-related though. “

“So are you two close to each other?”

“I have no clue. Besides, we’re constantly fighting.”

To be honest, Shirube’s only flaw was her frequent outbursts as a result of loving me too much.

“How about you, Ayaka? Do you have any siblings?”

“I did…… My older sister.”

“It was…… Well. Insensitive of me to ask.”

“It’s okay. I know you didn’t mean any harm.”

“Ah……”

I ended up seeing Ayaka’s cuteness whilst she gladly chatted away.

“Smile ……”

“……?”

“You look cute when you smile. I wish you would show it to our entire class.”

“What are you talking about?……”

Strangely enough, Ayaka spoke in a hasty manner.

“I’m sorry. What I meant was that you’re a good person. You’re way out of my league. So why don’t you express some emotion?”

“I’m okay…… With myself.”

“I guess you’re just tired. But you can smile when you’re happy, or cry when you feel lonely. If you do that, the people you cherish will also feel happy.”

“…………”

After what I said, Ayaka fell silent and looked down. It didn’t seem like she took it in the wrong way, though.

“Aha. Where were we again?”

“Susumu”

“Yeah? …… Woah!”

Ayaka hugged me.

“ H-hey…… What’s wrong?”

“Please…… Hurry up……”, Ayaka said as she clung to me.

“Ayaka……”

Ayaka trembled while holding her shoulders.

“Uhh…… Uhh”

“What’s wrong, Ayaka? Did I say something wrong?”

“…………”

Without saying a word, Ayaka continued to cry into my chest.

It felt like I was wrapped in her small shoulders.

“Have you calmed down?”

After a moment, Ayaka stopped crying and nodded like she was dozing off. Then, she slowly loosened her grip.

“I’m sorry…… Did I bother you?” Ayaka asked, her eyes looking up at me.

It was the first time I’d ever seen her wear that expression.

“Oh no, you didn’t. It’s just that I rarely see you looking that way, Ayaka!” Hearing those words from me made Ayaka blush.

“I could only show it to you…… Susumu.”

“All of our classmates are nice people…Well, Tomaro may be an airhead, but he isn’t a bad guy at all.”

“I’ll be fine…… As long as I have you, Susumu.”

Crap…… She looked at me with those slightly tear-drenched eyes. It was ridiculously cute.

“Ah-ah-choo! What exactly were you saying?”

“Your answer…… Have you thought about it?”

“Yeah, about that. I’ve been thinking hard since yesterday.”

“Really?”

“As I’ve told you before, I don’t know you that well Ayaka. However, I did find you to be a nice girl from the very beginning.”

“If that’s the case, would you go out with me, then?”

“I…… guess it’s okay. I suppose it won’t be a bad thing if you and I would try to get to know each other more,”  I said sincerely.

I didn’t dislike Ayaka, and even though I didn’t know her well, I had entertained the possibility of dating her.

“Susumu”, Ayaka muttered as she stared straight at me with her large, doll-like eyes.

“Would you please go out with me?”

“Okay. I’ll go out with you, Ayaka.”

“I’m glad. I love you, Susumu,” Ayaka said while smiling like a little girl.

“Let’s always stay together from now on, okay? I won’t ever be separated from you. We are officially a『Couple』after all.”

“Well, it will be a ‘trial’,” I said, just to make sure.

“We may be called a ‘couple’, but……. Let’s just keep our relationship casual whenever Shirube’s around, okay?”

“I won’t do that,” Ayaka responded, quickly shaking her head from side to side.

“She’s just your friend. She doesn’t have the right to invade OUR space. And besides―”

“Hey, hold it right there,” I interrupted.

“You may not care about who Shirube is to me, but I’m the only one who gets a say in this matter.”

“But why? Aren’t we a ‘couple’?”

“Because I’m an older brother.”

“……?”

“Because I’m HER older brother.”

“Do siblings keep their romantic experiences secret from each other?” Ayaka retorted keenly.

“I’d appreciate it if you stayed out of this. I suggest that you stop doing anything of the sort in the future as well. I know it sounds complicated, but this is the only favor I’d be asking from you.”

“Susumu, we’re a couple, aren’t we?”

“Yes. I’ll do my best to love you, but for that to happen, I’d like to know you better. I want you to understand my situation.”

“A lot of things are troubling you, right?”

Ayaka’s eyes twinkled eerily in anticipation.

“Don’t cheat on me okay? Or else, I’ll kill you.”

“Y-you’re kidding, aren’t you?”

“Who do you think I am? Would you care to test me?” Ayaka expressed her cruelty through a cold-hearted laugh.

“Okay, I won’t.”

What if she was trying to make Shirube jealous?

“Anyway, how about discussing what we should be doing as a couple starting today?”

“Gotcha. Now that we’re lovers, let’s go to my house first. Shall we?” Ayaka asked as she lightly stood up.

“Your house? Why?”

“Isn’t that a natural thing for couples to do? Plus, my dad’s home tonight, so you can just greet him.”

“You’ll introduce me to your parents? Oh yeah, that’s right. I’ll just greet him, nothing more.”

“Were you fantasizing about something just now?”

“Oh no, I would never do that! No way!”

“I’m totally fine with it. I would’ve done the same to you.” Ayaka seemed unfazed as she dropped these shocking remarks.

Speaking of which, was Ayaka’s family well-off?

As I was pondered, Ayaka pulled me by the hand,  and we walked for about ten minutes. Once we arrived― An outrageously huge mansion stood before us.
