Hikigaya's Inner World of Spring

After enduring a long torment...

Under Haruno's gentle coercion, Hikigaya had no choice but to take several couple photo booth pictures with her.

Once the photos were taken, Hikigaya thought that was the end of it.

But to his dismay, Yukinoshita suddenly suggested taking a few more pictures with their phones—just in case there were any loopholes.

Haruno gave her little sister a big thumbs-up.

Hikigaya let out a bitter sigh.

Was his own girlfriend really not going to save him at all?

No—wait!

It wasn't that she wouldn't save him.

She was probably just enjoying the show, wasn't she?!

Damn it!

Only an absolute fool would fall for a sadistic devil like Yukinoshita!!!

In the end, Hikigaya was forced to take a few more intimate photos with Haruno—this time on their phones.

And the one taking the photos... was none other than his own girlfriend, Yukinoshita.

"Thanks, Yukino-chan! And of course… thanks to you too, Hikigaya-kun~" Haruno grinned, looking thoroughly satisfied.

"You'd better find yourself a boyfriend soon," Yukinoshita said flatly.

"Next time, I won't be lending you Hikigaya-kun."

"Mhm, got it."

Haruno nodded with a smile.

"It's getting late. I'll drive you two home."

Neither of them objected.

Shortly after, due to their different home addresses, Yukinoshita was the first to be dropped off.

Taking the elevator upstairs, she arrived home within minutes.

However—

Just as she was about to relax on the sofa, she suddenly froze, her eyes widening.

[Ding! Haruno Yukinoshita, sitting in the driver's seat, just climbed into Hikigaya Hachiman's lap in the passenger seat...]

"???"

Yukinoshita was dumbfounded.

"In the car? That means...!"

She covered her mouth, her heartbeat accelerating.

Wait a minute!!

Could it be that her sister was planning to… do it with Hikigaya-kun right there in the car?!

What happened to behaving herself?!

Haruno, you traitorous big sister!!

How could you go after my Hikigaya like this?!

I even let you borrow him earlier!!

Ughhh!!

Yukinoshita was completely thrown into chaos.

What should she do now?!

There was no way she could rush over and stop it in time.

Was she really going to let her sister take her boyfriend?

Her heart was in turmoil—filled with shock, panic, and… a strange sense of anticipation she couldn't quite explain.

---

Meanwhile, inside the blue sports car—

Hikigaya regretted everything.

He regretted ever agreeing to sit in the passenger seat.

Because—

Not long after they had started driving, Haruno suddenly pulled over.

Then—

She unfastened her seatbelt.

And out of nowhere, she leaned into his lap.

Holy crap!

If he had known this woman would be so bold, he wouldn't have agreed to this no matter how much she insisted!!

"Haruno-san, w-what are you doing?"

"You should call me 'Onee-san'~"

"Ugh… P-please respect yourself, Haruno-san!"

Hikigaya desperately tried to push her away.

"Heh… just as I thought."

Haruno pulled back into the driver's seat, her voice suddenly turning cold.

"Hikigaya-kun, you smell like another woman."

Her smile remained, but there was an unmistakable chill in her tone.

"!!"

Hikigaya's expression stiffened.

"Haruno-san… what are you trying to say?"

"Hikigaya-kun, you've been getting quite close to a lot of girls lately."

"And not just close—you seem very intimate with them."

"!!!"

Hikigaya's pupils contracted.

He recalled how Haruno had conveniently appeared at the vacant lot last time.

A chill ran down his spine.

"W-what exactly are you trying to say?"

"Nothing much. Don't be so nervous."

Haruno smiled again, but this time, it was the kind of smile that sent shivers down his spine.

"I just hope you remember your position."

"..."

Frowning, Hikigaya fell into deep thought before taking a slow breath.

"So that's your real reason for coming to see me, huh?"

The whole "pretend boyfriend" thing—

That was just an excuse.

Her real purpose was to warn him.

"Heh. As the future man of the Yukinoshita family, of course we'd be keeping an eye on you."

"Not just me—even Mother is watching closely~"

"...!"

Hikigaya's eyelid twitched.

If that was true—

Then Yukinoshita's mother showing up last time was no coincidence either.

They had both been watching him all along!

Terrifying.

If Haruno and Yukinoshita's mother ever found out that he had cheated on Yukinoshita... Hikigaya didn't even want to imagine what kind of punishment those two demons would unleash upon him.

"In my heart, there is only Yukinoshita. Now, in the future, and forever. That will never change."

Hikigaya's voice was calm—

But beneath it lay an unwavering resolve.

"We'll see. Just don't disappoint us."

"I won't."

Hikigaya said firmly.

"But Haruno-san—"

"You should restrain yourself a little. It'd be best if we had as little contact as possible."

"Oh?"

Haruno blinked, looking slightly surprised.

Then, all of a sudden—

A mischievous smile spread across her face.

"What's this? Afraid you won't be able to resist Onee-san's charm?"

"Wait, what— no, don't come any closer!!"

"Fufu~ I'm not like those other women, you know~"

Ignoring his resistance, Haruno leaned in with a smirk.

"If Hikigaya-kun wants me... well, I might just say yes~"

"Ha?! You—"

"How about a package deal?"

"Since we're all family anyway~"

She winked playfully.

Hikigaya's face turned bright red.

Then he took a deep breath and said in a serious tone—

"Stop—stop joking around!!"

Inside the car, the two of them continued their back-and-forth.

Minutes later—

Haruno finally dropped Hikigaya off at home.

Hikigaya didn't waste a second—he practically bolted out of the car and ran for his life.

Meanwhile, in the driver's seat, Haruno didn't leave immediately.

Instead, she turned to look at the white dress shirt Hikigaya had taken off earlier, still sitting in the back seat.

She stared at it.

And kept staring.

A few seconds later—

Haruno quietly picked up the shirt.

Examining it closely.

"...Sigh. If only it wasn't her..."

---

On the other side—

Yukinoshita let out a sigh of relief as she sat on the toilet.

Finally—

She could go to the bathroom in peace.

But.

Even as she relaxed—

A strange feeling of disappointment crept into her heart.

She had been so sure her sister was going to do something to her boyfriend in the car.

But in the end, nothing happened.

Not even a kiss.

That was just...

Yukinoshita's face flushed red.

She patted her cheeks.

"Cough! What am I even thinking?!"

"There's no way Hikigaya-kun would sleep with my sister!"

Taking a sticker photo together was one thing.

But sleeping together...

Ugh!!

They were sisters, for crying out loud!

Sisters sharing the same husband—?

That was way too taboo! Absolutely impossible!!
