About the Case of Me Being Reincarnated as a Side Character Who Got Kicked Out Immediately Of The Story, but the Heroine, Who’s My Yandere Fiancée, Won't Leave Me Alone

Chapter 50: My little sister is a master at closing the distance

“Haha, how many years has it been since we last took a bath together, Akito?”

“…I dunno.”

I tilted my head, wondering how things had ended up like this.

After finishing my dates with Arisu and Amane, I had come straight home, only to be suddenly invited by my dad to have a talk in the bath.

“People have been speaking very highly of you lately. Even the servants, and Minato too, see you differently now… Arisu-chan, Masaki-kun, and Ichika-chan all have good things to say about you.”

“…Well, that’s nice to hear.”

For some reason, I felt oddly ticklish at those words.

Maybe it was because I was talking to my father, or maybe it was because I’d taken over this body that I felt so uncomfortable.

(…Dad, huh.)

Akito’s father, much like his mother, hadn’t played a major role in the story.

But now that I had become Akito, if our conversations even slightly aligned, we’d inevitably end up spending more time together.

(…Kind, but a bit airheaded too, huh.)

My father was, above all else, a kind person.

He could be strict when necessary and always put his heart and soul into his work, producing results—an admirable way to live.

But when it came to Akito, he had been far too lenient… No, perhaps he had been strict, but in the end, he still let Akito’s reckless behavior slide.

“…Hah, well, not that it matters now.”

“Hmm? What’s wrong?”

“Nah, it’s nothing. You know, Dad, I think I’ve been pretty lucky.”

“Oh? Only just now realizing that?”

“Maybe you should’ve scolded me more, you know, to knock some sense into the old me.”

“…You’re the one saying that?”

I laughed at how spot-on his response was, and my father chuckled along with me.

“I always believed you would change someday… though saying that now might sound like an excuse.”

“…I really have changed.”

“Yeah, you have… You’ve changed a lot.”

Changed… No, more like completely transformed.

The only one who knew my insides were different was Arisu.

Even if I told my father, I doubt he’d believe it… not that I planned on telling him anyway.

(Thinking about it like that… I do feel kinda guilty.)

In a way, I had stolen Akito from these people.

Considering the kind of person Akito originally was, I couldn’t bring myself to care much about that… but to them, the fact remained.

“…Phew.”

I sighed, realizing I had been thinking too much, and scooped some water to wash my face.

It didn’t wash away the uncomfortable feelings swirling in my chest, but it helped a little.

“Hey, Dad.”

“Hmm?”

“I guess… well, I’ll just do what I can. And I’ll try to do more than I can now, too.”

“I see.”

“Yeah… So, you and Mom, just keep watching over me, okay?”

“Of course. I’m looking forward to it.”

With that, I left the bath first.

I hadn’t intended to dwell on things too much, but by the time I reached my room, I still felt somewhat weighed down.

Maybe talking to Arisu would help clear my head.

“…Wait, Minato?”

“Ah, welcome back, Nii-san.”

When I returned to my room, Minato was sitting on my bed.

I walked over, wondering what she was doing there, and noticed that today, she wasn’t dressed in her usual boyish manner—she looked like a proper girl.

(…Damn, Minato is seriously hot.)

Her face hadn’t changed at all, and yet, now that I recognized her as a girl, I found myself noticing all sorts of things.

Her soft, pouty lips, her slightly flushed cheeks, her ample chest, her perfectly shaped hips… Sure, her bust was an obvious change, but everything else had always been the same. So why was I so hyperaware of it now?

“You need something?”

“Not really… Hmm, actually, if you count ‘wanting to be with Nii-san’ as something, then yes~♪”

“…Haha, I see.”

What a cute little sister.

She smiled brightly, kicking her legs playfully as I sat down beside her.

Then, she leaned in, resting her head on my shoulder.

A gentle, sweet scent filled the air, and I found myself wondering what it was—but no answer came to mind.

“Did you have fun on your date with Arisu-san and the others?”

“Yeah… though there was a bit of a hiccup.”

“A hiccup?”

I told her about what had happened with Amane. It wasn’t really a big deal, but still.

Minato laughed, saying it was just like me, then casually added—

“Well, Amane-san is gorgeous, so of course she’d be popular. But, you know… she’s basically already yours. That guy was just out of luck.”

“Hey, don’t say ‘already mine’… And where’d you even learn that kind of phrase?”

“Maybe not yet, but eventually, right? You accepted her feelings, after all. As for where I learned it… The internet is a wonderful thing.”

“…What, you been reading dirty manga or something?”

“Yup.”

She admitted it without hesitation.

Minato pulled out her phone, tapped on it a few times, then showed me her screen.

It was a list of manga she’d bought—mostly shoujo romance, but among them, there were quite a few spicy ones… And a lot of them had the “big brother x little sister” theme.

Not only that, but she had been buying them recently, in quick succession.

“…So you read this kind of stuff too, huh.”

“I haven’t told anyone, though. But, you know, even in lewd manga, if the story is good, it’s really good. I got kinda hooked.”

“Yeah, I get that. Some of them are crazy well-written.”

We ended up talking about manga for a while.

Minato knew that the old me never read manga, and yet, she never once looked at me like I was acting strange.

Or rather, since I was an otaku who had consumed countless anime and manga, I got so into the conversation that I didn’t have time to worry about it.

“…Haha, thanks, Minato.”

“Eh? For what? For showing you lewd manga?”

“No, not that… Just, thanks.”

I had felt heavy-hearted when I came back, but after talking to Minato, that feeling had disappeared completely.

I wanted to express my gratitude, even if she didn’t quite understand why.

Minato tilted her head, confused, but her expression was so cute that I couldn’t help but pat her head.

“…You know,” she murmured.

“Hmm?”

“You only spoil me like this because I’m your little sister… right?”

“Huh? Oh… Well, yeah, I guess. Even though you’re a girl, I don’t feel the need to hold back around you, probably because you’re Minato.”

“Yeah… That’s fine. That’s totally fine… So once we get even closer, you can do all sorts of things with me, okay? You can use me to test things out… okay?”

“…………”

I was fully aware of Minato’s not-so-subtle advances.

But honestly? It was too much to process.

I couldn’t even wrap my head around it right now.

“…Maybe someday.”

“Eh? Oh… Yeah! Someday!”

…Wait.

What the hell did I just say?!

I was just fumbling for words, and my mouth ran ahead on its own!

Minato’s smile was brighter than ever, as if she had just found undeniable proof of something she had long suspected.

She looked exactly like a little sister who was just dying for her big brother to have his way with her.

“…I should sleep early tonight.”
