While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 13: While on a Date with a Beautiful Girl, We Somehow Crossed a Line (Part 4)

Chapter 13: While on a Date with a Beautiful Girl, We Somehow Crossed a Line (Part 4)

“No… you’re kidding, right…?”

Her voice was faint, trembling, barely audible.

“You’re just teasing me… aren’t you…?”

“No, Yuu. I’m serious.”

I laid out the truth, unflinching.

“This thing between us? It ends today.”

Our relationship, as it is, stops here.

With firm resolve, I met her deep black eyes head-on.

“Why…? Why would you say that…?”

Her words carried a hint of blame, her voice quivering, her eyes glistening, her expression pained.

“Why now, of all times…?”

Tears welled up in her eyes, but she didn’t look away.

They spilled down her cheeks.

Seeing them, I couldn’t help but feel my heart skip.

She’s beautiful.

She’s cute.

…A little perverse?

“Hey, Yuu.”

“…?”

She tilted her head, her face full of unease.

I looked up at the spreading clouds.

It was so sunny during our date, I thought. How quickly things change.

“Lots has happened, hasn’t it?”

“…Yeah.”

She nodded, as if savoring the weight of it.

Yeah, we’ve built up a lot over time.

So many moments together.

“I think it’s time to end this kind of relationship.”

For her sake. And mine.

“Lately, I’ve been painfully aware of my own helplessness. Thanks to you, of all people.”

“…”

I gave a wry smile, feeling pathetic, and looked at her.

My childhood friend, my neighbor, my partner in this fake relationship—a precious stranger, in a way.

The girl who, in some sense, changed me like this.

Her impact on me is immeasurable.

But I didn’t hate this change.

I was starting to not hate myself.

“So, let’s end it.”

“…What?”

Yuu’s eyes widened, as if she’d realized something, staring at me.

“Wait, do you mean—!”

The color returned to her pale face.

Her cheeks flushed bright red.

“Ren-chan! Are you saying—!”

“—Oh?”

Drip… drip…

Raindrops began to fall from the clouds.

“It’s raining.”

The sky was blanketed in gray.

It’d pour soon.

“Ren-chan…”

“It’s coming down. Should we head back?”

“…”

Ignoring her hesitation, I took a step forward.

I didn’t bring an umbrella, but we could grab one at a convenience store on the way to the station.

As I thought that—

“…Wait!”

Yuu grabbed my sleeve as I passed her.

“Not yet…”

Her face was scarlet. Her lips trembled, hesitant to speak, but her voice, squeezed from her shaking throat, was surprisingly clear.

“I don’t want to go home yet…!”

She looked away, shy, speaking softly.

“…Alright. Let’s walk a bit.”

I nodded to her, avoiding my gaze, and we started walking.

Not holding hands.

Our steps carried us past the park, toward the bustling streets.

No going back.

I won’t go back.

Feeling a near-certain conviction pounding in my chest, I walked through the light rain with a tense expression.

Just the two of us.

“…I can’t say anything about Tsuki-chan.”

Yuu suddenly muttered, almost self-deprecatingly, under her breath.

We walked through the sparse, tiny raindrops, looking up at the sky.

“What do you mean?”

“…I’ve been acting weird lately, haven’t I?”

“That’s not—”

—No.

She’s right.

Thinking back, Yuu’s behavior has been unusual for her.

To outsiders, she’s a beautiful, perfect girl—an honor student who excels at academics, sports, and housework.

But lately, the expressions she’s shown me and Usotsuki-chan have had something more than just familiarity.

“When I thought Tsuki-chan might be getting bullied, I got scared.”

“…”

Usotsuki-chan’s got a quirky personality.

Hard to get close to, elusive at best, and bluntly, not the most reliable friend.

Her unstable emotions and sometimes calculated actions make her hard to pin down—she flips between trustworthy and unpredictable.

In short, she’s hard to read.

Hard to trust.

Because of that, she occasionally rubs people the wrong way, drawing their ire.

She’s a beauty when she keeps quiet, but it’s like she wants to be disliked sometimes.

Even if others truly hate her, she doesn’t hate them back.

Even when harassed, she doesn’t harass others.

That’s why, when I saw her facing “harassment,” I treated it as bullying and stepped in with Yuu—during that whole Mizuno thing.

She’s like a kakapo, if I had to compare.

A flightless bird from a peaceful island, with no defenses against predators, just hiding and trembling. A lonely creature that’s learned pranks get attention.

Usotsuki-chan’s like a kakapo who’s mastered mischief.

“You were that worried about her? You?”

I know Yuu’s kind and not heartless.

But when it comes to relationships, she’s got a sharp, critical eye.

And she’s pretty tough on Usotsuki-chan.

“No, it wasn’t about Tsuki-chan herself.”

Yeah, she was hard on her.

“I thought if Tsuki-chan was being bullied, you’d definitely step in to help her.”

“…”

I can’t deny it.

…No, she’s spot-on. Looking back, all I did was help Usotsuki-chan.

“I knew you’d do that… and you did. That’s why I got so worried.”

“…”

The source of Yuu’s anxiety.

The worry that’s been shaking her to her core.

“…Hey, do you remember? Back when we were still in elementary school… that time.”

Her voice was calmer now, her cheeks faintly flushed, as she spoke quietly.

I kept my eyes forward, nodding slightly.

I remember that time too. Not as vividly as she does, probably…

But for her, it’s likely an unforgettable memory.

She began to recount the events, carefully, as if piecing them together one by one.
