Chapter 76: Blonde Two-Side-Up Suspicious Person

Having finished our weekend routine of “Masami-chan duty,” we returned to the station closest to home.

It was already past 1:30 p.m.

“Took a while. It’s a bit late, but wanna grab lunch?”

“Sure!♥”

“Any place in mind?”

“Anywhere’s fine!♥”

“If you’ve got no preference, how about a family restaurant?”

“Let’s go to a family restaurant then!♥”

“Alright.”

Still feeling Yuu’s chest as she clung to my arm.

With my blissful right arm in tow, I walked away from the station toward the family restaurant.

There are plenty of eateries near the station—izakayas, gyudon chains—but I wasn’t in the mood for noise. A place with partitioned tables where we could eat calmly together sounded better.

“Nfufufu!♥”

Yuu seemed content just walking close like this, which was kinda soothing.

—And then the incident happened, as we strolled through an unremarkable alley.

“…”

“Yuu? What’s wrong?”

“…”

Not ignoring me, but—

She was staring straight ahead, down the alley, silent.

It was a bit eerie.

…Or maybe it was the tension I felt as she tightened her grip on my arm even more.

“…Ren-chan, let’s go that way.”

“Huh? But the family restaurant is straight ahead—whoa!”

Yuu stopped abruptly, forcing me to halt as she pulled me.

Her gaze remained fixed forward.

Wondering what she was staring at so intently, I looked closely too…

—And I understood immediately.

“—Oh, busted, huh?☆”

A carefree voice came from behind a utility pole, and out stepped a beautiful girl in a white dress.

“So hot and heavy, you two!♪”

There stood Yakko Tsukimi, her blonde two-side-up hairstyle bouncing energetically.

“You two, what’re you doing in a place like this? Oh! Maybe a date?☆”

“No ‘maybe’ about it, it’s a date.”

“Tsuki-chan…”

I answered, a bit startled by her appearance, while Yuu, beside me, narrowed one eye, openly showing her displeasure.

“What about you, Tsuki-chan? Why are you here? What were you doing behind that pole?”

Yuu, gripping my arm tightly, spoke to Yakko-chan with a sharp tone.

At that moment, a breeze blew, making Yuu’s long black hair flutter—

…For a split second, I stupidly worried she’d turn blonde with rage, like some legendary warrior transforming.

“Nah, just a coincidence!☆ I was actually about to go shopping or something.”

“No way it’s a ‘coincidence.’ You were obviously tailing us.”

“Whaaat? I wouldn’t do that! I’m not some stalker!☆”

“…”

Yuu and I couldn’t help but stare at Yakko-chan.

“Sorry, but Ren-chan and I have somewhere to be.”

Yuu took a step forward, but Yakko-chan’s words stopped her.

“There’s just a family restaurant up ahead, right? A bit further is a supermarket.”

“…”

Huh, is she planning to tag along? I wondered, but Yuu, still clutching my arm, froze, staring at Yakko-chan expressionlessly.

Might as well ask if she needs something.

“Yakko-chan, got something to say to us?”

“Can I come with?☆”

“Su—”

“—No way!”

Yuu cut me off, raising her voice. She glared at Yakko-chan, squeezing my arm tighter.

Oof… her, uh, chest! My heart’s pounding!

This must be the softness of happiness.

“Why are you always…! I’ll call the cops!”

“The police? For what?”

“You’re a stalker!”

“Whaaat? I said it was a coincidence!☆ Stop making accusations!”

“Tsuki-chan…”

Yuu’s face tilted downward, shadows pooling under her eyes.

As her grip on my arm weakened slightly, she reached with her right hand, searching. Her hand went to her flowing black pleated skirt—

“—!?”

She froze, as if realizing something, and bit her lower lip in frustration.

“…You got lucky, Tsuki-chan.”

“Huh? What?”

Judging by her fumbling, she was looking for something in her skirt pocket… but forgot it.

And in this moment, that was probably a stroke of luck.

I really don’t want a full-on fight breaking out in broad daylight in the middle of an alley.

Before their exchange heats up further, I’d better cool things down.

Yuu’s got some smoldering emotions, sure, but I can handle those.

“We were about to head to the family restaurant.”

““Huh!?””

My words caught them both off guard—Yakko-chan’s eyes widened in surprise, and Yuu whipped her head around to stare at me.

“No way, Ren-chan—”

I ignored Yuu’s tug on my arm and invited Yakko-chan.

“Wanna come, Yakko-chan?”

“Ren-chan!!”

“Really!?☆”

“Yeah.”

“Ren-chan…”

Yuu looked at me with clear dissatisfaction, but this wasn’t a thoughtless offer. I hope she gets that.

“(…Yuu.)”

“Eek!?♥♥”

“Whoops.”

I leaned to whisper an explanation in her ear, but she jolted, trembling. Guess I startled her.

“R-Ren-chan…♥ Is this okay?♥ In the middle of the street…♥♥”

“No, it’s not, calm down.”

I frantically stopped Yuu, who looked ready to sprout heart-eyes. To outsiders, it’s subtle, but she’s rubbing her chest against my arm. What…! Is this that so-called pai—wait, not now.

“…What are you two doing?”

Yakko-chan narrowed her sharp eyes, glaring at us.

Fair enough.

I’m wondering what we’re doing too.

“Ren-kun…? What’s up, you froze. Something on my face?”

“Nothing. Your face is fine, don’t worry.”

Brushing off Yakko-chan’s suspicion, I tried to calm Yuu, whose arousal switch was flipping, and whispered.

“(—Look, Yuu. Inviting Yakko-chan here—)”

“(…Nnh!♥)”

…I was careful not to let my breath tickle her ear, but my voice alone seemed to get her going.

Doubting she’d hold out long, I hurried my explanation.

“(Ignoring Yakko-chan might let her do something sneaky behind our backs. Keeping her close is safer, right?)”

“(Oh… that’s what you mean…♥ …Ah!♥)”

I meant to be serious, but Yuu’s exaggerated reactions made it seem like she was messing around. It made my caution feel foolish.

Being overly wary of Yakko-chan might cause misunderstandings too.

Let’s keep it friendly, casual.

“Yakko-chan.”

“What…?”

Up ahead, Yakko-chan, watching us, subtly reached for the utility pole beside her.

You can’t read exact emotions from every action, but you can guess the type of stress and what’s causing it.

My whispered talk with Yuu seemed to put her on edge.

“If you’re stalking us like Yuu says, could you stop?”

“…”

Yakko-chan stared at me suspiciously. I expected her to play dumb, but she seemed to be gauging my intentions.

“You don’t need to do that. I’m not running or hiding.”

Well, I’d resist, though.

“…Really? I can really come with?”

“Yeah.”

“Yay!♡”

“(…Ren-chan. You’d better make up for this later, okay?)”

“(Yeah, got it.)”

“(Yay!♥)”

…Honestly, I didn’t fully get what Yuu meant by “make up for,” but she’s always surprised me without ever making me uncomfortable.

Yuu and I understand each other’s non-negotiables and respect them, building what the world might call an “ideal” relationship. She knows that too, so she wouldn’t make unreasonable demands that’d ruin what we have.

We’ve got years of history, and I trust her for always staying close and caring about me.

…Sorry, that sounded cool.

Really, it’s more like, “Yuu’ll be fine, right?”

“Yay!☆ Ren-kun’s left side, secured!♡”

Yakko-chan bounced over, trying to link arms with me—

“No touching Ren-chan.”

“…Tch!☆”

Yuu’s flat, expressionless voice stopped her cold, and Yakko-chan pulled her arm back.

What’s up? Normally, Yakko-chan wouldn’t listen to Yuu and would’ve latched onto me anyway…

“…Could it be, Tsuki-chan, you’re really…”

“Who knows?☆”

“…”

With me in the middle, Yuu and Yakko-chan glared at each other, sparks flying.

The air crackled like electricity—or a storm? Two clashing forces, about to explode around me. Kinda scary.

No way this is the vibe for eating lunch together… but my stomach’s growling.

“Cut it out, both of you. We’re about to eat. Yakko-chan, don’t provoke Yuu. Yuu, you’ll tire yourself out getting so mad.”

“…”

“…Hm? What’s with you two?”

Whoa, they’re both giving me troubled looks.

Such awkward expressions.

“Come on, let’s go.”

“Ah—♥”

Yuu, still clinging to my arm, had no choice but to follow as I walked.

A beat later, Yakko-chan trailed behind, and we headed to the family restaurant.

All I wanted was to eat at a family restaurant… why’s it gotta be like this?

Still, this is my best shot as a guy with a girlfriend like Yuu.

Right now, being with me has loosened the reins on emotions she’d kept in check.

Her extreme actions stem from overwhelming affection and love for me, but she’s losing control over them.

On the other hand, Yakko-chan’s actions…

There’s no clear core to them, no driving force.

…No, there used to be, but that negative core was stripped away. Yet, even with that seemingly positive shift, she hasn’t recovered, just drifting aimlessly since then.

A self-destructing doll without the self-destruction, now just a doll… I’d never say that out loud, but that’s the vibe.

Her immature ego and emotions are still developing. Despite her sharp mind, her lack of social experience—or maybe lack of genuine social experience—makes her cling to unhealthy relationships, quickly overwhelmed by emotions. It’s the kind of conflict kids often face.

“Family restaurant, huh? Been years! So long!☆”

Swaying her white dress hem and blonde two-side-up hair, Yakko-chan smiled.

“Oh, you don’t go to places like that much, Yakko-chan?”

“Not really. Eating out’s a hassle, so I usually get delivery.”

No way.

“You rich girl! Bourgeois!”

“Haha, say what you want!”

“Rich, huh. More like, Tsuki-chan’s a shut-in.”

“Harsh! I go out if I’ve got a reason. If I’ve got a reason…”

So she barely goes out otherwise.

Not a full-on shut-in like my sister, but close enough to be a shut-in-in-training.

People like that can easily tip into real reclusion with the right trigger, so she should be careful.
