While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 23: Strong Sense of Unease ♡ Unease-Type Girl ☆ Usotsuki-chan

Chapter 23: Strong Sense of Unease ♡ Unease-Type Girl ☆ Usotsuki-chan

“The real liar is you, Ren-kun…”

Usotsuki-chan’s voice trembled, sounding like she was about to cry or burst with anger.

Her outfit—just a bra under an undershirt, panties below.

Practically naked, she straddled me—not quite riding me, more like pinning me down.

“…Liar.”

Those words.

“Liar.”

Over and over.

“Liar.”

Repeating endlessly.

“…”

How did it come to this?

Calm down, we can talk this out.

I swallowed those makeshift words.

…No, sorry, that was me trying to sound cool.

The real reason I didn’t say anything is because she was strangling me with both hands, and I couldn’t even speak.

Couldn’t even breathe properly.

Her grip was so strong, I realized she was dead serious—maybe even murderous.

So, yeah, I was lightly facing a life-or-death crisis.

“… …”

My vision flickered, lights flashing on and off.

Was blood pooling in my head, or not reaching my body? Was this literally “my blood running cold”?

I couldn’t tell anymore.

A nostalgic feeling.

Like being drunk on euphoria, thinking, If I just let go, it’d be so easy.

Of course, the current me wouldn’t choose that path.

“Liar.”

Her voice dripped with an emotion—anger, sadness, something in between.

Usotsuki-chan’s true feelings.

Not a lie… her raw emotions.

“I hate you, Ren-kun—”

“…”

Plop. A tear fell on my cheek.

With her defiant eyes, she stared into mine.

Her lifeless eyes welled up, tears streaming down.

She leaned closer, her dyed blonde two-side-up hair draping over my face.

My vision darkened under her hair, her face coming impossibly close.

Our noses brushed. Her trembling lips neared mine.

“I hate you, Ren-kun.”

She closed her eyes and pressed her lips to mine.

*

A cold, hard sensation touched my lips.

“…”

“—Mmh…?”

Usotsuki-chan, kissing me, froze as she felt something cold and hard, her expression clouding.

She pulled back, instantly realizing what happened.

“…Ren-kun… haha…”

She loosened her grip on my throat, narrowing her eyes and laughing mockingly.

Her gaze fixed on the smartphone I’d slipped between her lips and mine.

The screen, likely showing “Recording” with a ticking counter, numbers climbing.

Proof that these past few minutes were being recorded.

“Cough… cough… whew, that was close.”

Free to breathe again, I coughed and sighed in relief behind the phone.

Usotsuki-chan’s expression turned lonely as she spoke.

“…You know, Ren-kun, you turn into such a clueless idiot around Yuu-chan… but normally, you’re shockingly sharp…”

“Am I that clueless?”

It stung to hear that. I’d like to think I’m not that bad.

“Only around Yuu-chan… You’re so unaware of it… Honestly, it hurts even me to see you like that…”

“S-Sorry…?”

Her narrowed eyes held a smile, but her gaze was still wet with tears.

“Ren-kun.”

Her voice trembled, a whisper.

“…That’s why I hate you…”

“…”

Calling me a liar, saying she hates me—Usotsuki-chan’s really laying into me today.

Seeing her raw, real side for once caught me off guard, but to think she’d come at me so boldly, so directly, to shatter my peace like this.

“…Look, Usotsuki-chan, about that.”

“…?”

I steadied my breathing, checking she’d lifted her face, and spoke to her.

Trying to bring her back to her senses.

“You don’t kiss someone you hate. Right?”

I said it plainly, stating the obvious.

“…”

She looked down at me, still straddling me.

Blank-faced.

Her cold eyes spilled tears as she spoke.

“God… it’s that devotion of yours.”

Thud. She lightly punched my solar plexus, continuing.

“That kindness.”

She hit my chest weakly, over and over.

“…That honesty. That self-discipline. That care for others, that empathy for others—it’s what I—”

And then, Usotsuki-chan—

“—what I hate most.”

“—Gah!?”

She grabbed my wrist and shoved the phone hard against my mouth, sealing it. A desperate move at this point. Totally unexpected.

“That wonderful side of you, more than anything, more than anyone—”

“…Mph!?”

She leaned in, pressing her lips to the phone’s screen over my mouth—

“I hate it.”

Chu. She kissed it.

*

A little later.

In the hallway just past my house’s entrance.

Usotsuki-chan was still slumped on the floor, legs tucked inward, barely clothed—just her underwear.

“You okay now?”

“…”

No answer.

She stared downward, dazed, like her soul had left her, tears streaming endlessly.

A thin river flowed from her lifeless eyes.

The stream broke at her chin, sparkling droplets falling to the floor.

The drops pattered onto the hallway floor and the back of her hand.

“Usotsuki-chan. Put your clothes on. You’ll catch a cold.”

“(…)”

Like she was broken.

Like something had broken her.

She just cried.

As if something precious had been tainted.

As if she’d lost something dear.

“(…)”

“…Hm?”

I strained my ears and noticed—she was muttering something, wasn’t she?

Whispering under her breath.

“(…Ren-kun… violated…)”

“Hey… Usotsuki-chan…?”

What was she saying? I stepped closer, standing beside her slumped form.

“…Ren-kun violated me.”

“Hey… Usotsuki-chan?”

That was a dangerous line.

“Violated”? By me?

An unbelievably ominous phrase.

She needs to stop that, like, now.

“…No, forget that—put your clothes on first. Come on, Usotsuki-chan.”

I set her discarded sweats beside her.

“You’ll catch a cold.”

“Ren-kun violated me… Ren-kun violated me… Ren-kun violated me… Ren-kun violated me…”

“I didn’t.”

“Ren-kun assaulted me… Ren-kun assaulted me… Ren-kun assaulted me… Ren-kun assaulted me…”

“I didn’t.”

“Ren-kun raped me… Ren-kun raped me… Ren-kun raped me… Ren-kun raped me…”

“Didn’t happen.”

No matter how many times I denied it, no matter how firmly, Usotsuki-chan kept muttering, broken, repeating herself.

She’s dead set on making it seem like I attacked her.

Is she gripped by victim delusion… or is that even the right way to describe it? How do you even label her right now?

—As I stood there, dumbfounded and exhausted, at a loss.

“…”

Grab. Usotsuki-chan snatched her clothes from the floor and stood up.

“H-Hey… You okay, Usotsuki-chan…?”

“…”

Ignoring my concern, she slipped back into her sweatpants and sweatshirt, then pulled her sweater on.

Back to the outfit she arrived in, just like that.

The only difference was her face—puffy from crying, tear stains around her eyes.

I thought she’d pulled herself together, but—

“You okay, U-so-tsu-ki-chan—”

“—Stop it.”

“…?”

Her sharp words made me tilt my head.

“Stop calling me ‘U-so-tsu-ki-chan.’”

“…This nickname?”

“Yeah.”

She glared at me, her expression fierce and defiant.

Hard to believe she was just a wreck moments ago—her composure was returning, at least on the surface.

“That nickname—”

“Not stopping.”

“…!? Why not!?”

She lunged toward me, almost confrontational, but when she met my eyes—

“…!?”

She flinched, trembling, and took a step back.

…Why’s she so scared? I don’t get it.

“W-Why… such a weird nickname…”

“Wanna know?”

“I-I mean, it’s weird, right? It’s just me with this… embarrassing name… You don’t use it in front of others, but still…”

She genuinely seemed to hate the “Usotsuki-chan” nickname, but I have my reasons—and it’s about time I explained them.

As she suspects, I don’t call her “Usotsuki-chan” to humiliate her in front of others.

“Remember the Mizuno thing recently?”

“Huh…? Yeah, I remember, but…”

She answered, a bit wary.

“The blame for that issue lies with Mizuno, who harassed you. The bully’s the bad guy.”

“Tch, obviously. Bullying’s wrong…?”

She glanced up, reading my face.

Sure, she has a habit of toying with people, but she’s sharp enough to pick up on vibes—classic Usotsuki-chan.

So—exactly because of that—she should be able to navigate better.

“What’s your point…?”

“Hmm…”

I watched her closely as I spoke.

“Mizuno’s the bad guy—but as for the cause of this kind of trouble, I think it’s on you, Usotsuki-chan.”

“Huh…? I’m not the bad guy!”

She tilted her head, confused, so I added more explanation.

“This time, your weakness was clear. The circumstances, the trigger, were unusual, sure. But trigger or not, you’d have ended up cornered like this eventually.”

“…Eventually, huh?”

“Yeah.”

I nodded, seeing her start to process it.

“Bullying, at its core, is a kind of… expression of maintaining order.”

“…?”

“In other words—”

Bullying stems from a sense of justice.

It singles out the odd one out, persecutes, excludes, or isolates them. It’s about rejecting the “bad” or the “minority.”

That’s the essence of justice, the true face of righteousness, and bullying is its warped manifestation.

Basically, bullying doesn’t easily target those who “fit in,” who share the same perspective or status.

“In the end, Usotsuki-chan, you’re still an outsider. You keep being someone who makes others feel uneasy.”

“…”

Finally, she seemed to get what I was driving at.

*

The Mizuno incident.

I resolved the issue of “Usotsuki-chan being harassed by Mizuno,” but that was just a band-aid fix.

It didn’t address the root cause.

Like taking medicine to ease symptoms but not changing the lifestyle that keeps the illness coming back.

The factors that make her a target for bullying are still inside her.

*

In a society built on human connections, clashes are inevitable. You’ll always meet people you just don’t click with. Growing stronger—maturing—helps you deal with that.

But if every new environment, every step forward, slams you into walls that break your spirit, you’ll collapse before you can grow.

So, to avoid breaking, Usotsuki-chan needs to grow while she still can, within the limits she’s allowed.

She needs to learn to honestly rely on others in a pinch, to build trust-based friendships—not completely open, but close enough.

She needs to stop saying things that deliberately make people dislike her—testing their tolerance with suggestive remarks—and consider how those affect relationships, even the unseen ones.

Normally, these are social skills you pick up with age and experience.

Her personality—her lively, outgoing facade paired with a fragile, sensitive core—could’ve been her strength, a charm like “being good at leaning on others.”

But her heart is more delicate than it seems, too weak to handle the scars that pile up as she grows.

She’s not manipulative scum, but her difficult personality makes it hard to form close bonds—with friends, lovers, or anyone important. That’s what she needs to fix most urgently.

Specifically, her secretive, overly introverted nature, even with close friends, needs to change. She should open up more, at least to friends. Of course, her past and environment impose limits, but…

As a high schooler, still free from adult responsibilities, she should work on these bad habits before they cause irreparable damage.

…To be clear, these are issues that usually resolve with age.

Normally.

But for her, she’ll break first. Given her home life, she’ll probably shatter beyond repair at some point.

That’s how I see it, at least.

That’s why I gave her the nickname “Usotsuki-chan.”

To call out her biggest flaw, the main thing holding back her growth.

*

“…You sound like a teacher. Or a parent.”

“…”

Usotsuki-chan cut into my well-meaning lecture (carefully curated, of course).

“Parent-like… or maybe, like someone’s big brother?”

“…”

I clammed up.

What I was trying to convey… and the side of it she likely picked up on—it’s true, too.

“Speaking of, your sister became a shut-in because of bullying, right?”

“…”

Of course, my sister came up.

“…I get it, Ren-kun.”

Her voice trembled terribly.

“You care about me.”

It sounded utterly despairing.

“You protect me from all sorts of things.”

“…”

“Because you’re treating me like a substitute for your sister.”

“…”

Bingo, she snorted.

But despite her mocking tone, her eyes—

Tears welled up again, streaming down her cheeks.

“You’re the worst, after all.”

“…”

“You’re really scum, Ren-kun.”

“…”

Usotsuki-chan’s defiant eyes were now just sad, shadowed with grief.

Her eyes drooped, tears streaming silently.

“My feelings were doomed from the start, weren’t they?”

“That’s not it. I’m not treating you like a substitute for my sister.”

I couldn’t deny it strongly, though.

“Liar… You’re way more of a liar than I am, Ren-kun…”

Usotsuki-chan’s hidden feelings.

All this time.

“This is cruel… It’s not fair… You knew how I felt…”

I can’t say I was completely clueless.

But I didn’t realize her feelings were this strong.

Only now, facing her gaze and emotions head-on, do I feel the cruelty of what I’ve done to her.

…But thinking of her—no, that excuse feels empty now.

“…Hey, Ren-kun.”

“What?”

She murmured, barely audible.

“Being too kind… it’s cruel, isn’t it?”

“…Maybe.”

I felt my hands clench, a strange tension rising.

“You’re too kind, Ren-kun.”

“…”

You’re kind. Too kind. Those words rang in my head like tinnitus.

Those words, directed at me, were rarely compliments.

Kindness can make people suffer.

Sometimes, being kind is a mistake.

It can make things worse.

I don’t really understand the ideal balance of kindness or firmness.

I grew up thinking you’re kind to yourself, you punish yourself.

That’s tricky, hard to navigate, and I still mess it up a lot.

I don’t want to hurt anyone, just be kind, but it can lead to bad outcomes.

It doesn’t work out.

I can’t get it right.

…And this time, of all times.

With a dear friend I once wanted to protect.

I might’ve failed.

“I… know Yuu-chan’s secret.”

“…Secret?”

Everyone’s got one or two secrets they keep from others, but whether I’m curious is another matter.

“Yeah. Yuu-chan’s secret. One she’d never tell you, Ren-kun. Don’t you want to know?”

“I do.”

I bit instantly.

“But you don’t have to tell me.”

I let go of the bait just as fast. No fish bites a hook they see coming.

“…Pfft, haha!”

Hearing my answer, Usotsuki-chan laughed, broken and amused.

“But I’m gonna tell you anyway.”

My choice didn’t seem to matter to her.

If she speaks loud enough, I’d hear it even with my ears covered. To stop her from spilling Yuu’s secret, I’d have to physically shut her mouth.

“Telling someone who wants to know? The fault’s on the person who has the secret and got found out.”

“You do that, and Yuu will hate you.”

No, she’d straight-up see you as an enemy.

Yuu’s stronger now. Maybe it’s natural, given how much time has passed since we met.

Her heart and body have grown way beyond her childhood self.

“Being hated? Doesn’t bother me. It’s already too late for that.”

Right. I forgot. She and Yuu are like oil and water, so hostile it’s a mystery why they still interact.

“Being liked would be more trouble.”

“…That’s what I’m saying you need to fix.”

Her bad habit stared me in the face, and I couldn’t help but scratch my head.

“Why do you act like you want people to hate you?”

I had to ask—something I needed to make clear.

Probably a question that cuts to the core of her mindset. Would she answer honestly?

“Duh, that’s obvious.”

She blinked, then smiled through her tears.

“Because you accept me even when I act like that, Ren-kun.”

“…”

Warped, I almost said, but held back.

It’s hard to gauge how much my feelings toward her shape her choices. Is her answer a lie or the truth?

“If I rejected you, would you try to make others like you?”

“Dunno. If you rejected me, I might be so shocked I’d kill myself.”

“…”

“…Pfft, haha, hahaha! What’s with that face!”

She laughed, clutching her stomach, tears in her eyes, breaking down gleefully.

“…Haa. Man, it’s tough, huh? Being chased by two super clingy girls.”

She laughed, swearing, delighted in her breakdown.

“How’s it feel? Come on, how’s it feel right now?”

“Being chased by hot girls? Can’t complain.”

“But Yuu-chan’s not just hot—she’s probably a total freak, right?”

“No guy’s mad about his girlfriend being sexy.”

“Hahaha… That’s not what I meant… God, you’re such scum.”

My palms were sweaty, cold sweat trickling down my temple.

Talking to Usotsuki-chan right now feels ten times more intense than facing a thug.

Pure hostility would be easier to handle.

What I want to avoid is her self-destruction.

Affirming or denying her feelings right now—both are insanely risky.

“Look, Usotsuki-chan. If your feelings… your feelings for me are real—”

God, saying that feels so cheesy. I hate this. It’s like holding emotions hostage.

“—you really shouldn’t do self-destructive stuff. Don’t give up on yourself.”

“Haha! So desperate! Yuu-chan’s that important, huh? So hot and heavy! …Man, the difference between how you treat her and me…”

Usotsuki-chan. Real name: Yakko Tsukimi.

A classmate since middle school, a close friend to me and Yuu.

Someone I could talk to casually, at a comfortable distance, even when I was ready to ditch friendships for being too busy.

“Usotsu—”

“I told you to stop that name. Maybe I should bite my tongue off right here.”

“—Yakko-chan.”

“…Hehe ♡ Hahaha ♡”

Seeing me honestly switch to her name, she smiled faintly.

Then she looked down, away from me.

“…Would it have been better if I were Yuu-chan?”

She said something wild.

“Huh? Hey, Yakko-chan—”

“If I were Yuu-chan, your childhood friend next door, maybe by now—”

“Whoa, whoa, calm down.”

“Maybe I should’ve moved here when we were kids—”

“Calm down.”

My mind was spiraling toward something unthinkable.

To anchor Yakko’s heart back to reality, I shook her shoulders.

She looked at me, her head swaying.

Her eyes, barely focusing on me.

Gleaming eerily.

Her brown irises softened, pupils wide open.

As if trying to drink in every bit of visual information.

“You should go home for today, okay? Yakko-chan.”

“…Alright ♡ I’ll go home for now ♡.”

When I gently urged her, surprisingly, she complied calmly.

…No.

It was more like she suddenly started complying too calmly. The change was too abrupt.

“…I’ll walk you home.”

I called out to her back as she reached for the front door.

“No need ♡ You’re waiting for Yuu-chan, right? ♡”

“…”

Yakko, suddenly so agreeable, turned back with a smile I’d never seen before.

How did she know… that Yuu was coming over later?

That simple question didn’t make it out of my mouth.

I was just… overwhelmed by the intense unease she radiated—her uncanny aura swallowing me whole.

Why did this happen?

How did it come to this?

Those helpless questions swirled in my chest.

Did I, without a doubt, mess something up just now?

I couldn’t shake that feeling.

“See ya later, Ren-chan ♡.”

That sweet voice, mimicking someone.

That nickname someone uses for me.

That melting, blooming smile someone would show.

“From now on, call me Yakko, okay? ♡ Oh, and just Yakko, no honorifics ♡.”

Usotsuki-chan—Yakko Tsukimi.

“Some day, you’ll fill me up too, right? ♡.”

With a smile so beautiful it sent chills down my spine, she opened the door.
