Hikigaya's Inner World of Spring

"As expected of my dear little sister~"

Before Hikigaya could even get a word in, Haruno excitedly walked up to Yukinoshita and pulled her into a hug.

"Thanks! I'll return Hikigaya-kun to you as soon as I'm done with him~"

"Wha—Onee-sama?!"

Being held by Haruno, Yukinoshita involuntarily sucked in a sharp breath, her eyes instinctively glancing at her older sister's well-endowed figure.

"With your qualities, finding a boyfriend should be quite easy."

"I know, I know~"

Haruno grinned and puffed out her chest slightly.

"Alright, alright. I'll find a boyfriend sooner or later. I won't bother you lovebirds for help anymore, I promise~"

Yukinoshita shot an irritated glance at her sister's chest, then nodded and pushed her away.

"Don't waste time. Let's finish this quickly and go home."

"No problem."

Haruno responded with a bright smile before turning her attention to the mostly ignored Hikigaya.

Before he could react—

Haruno gently wrapped her arms around his.

"Hehe, couples taking photos together should wear matching outfits, right? I actually thought ahead and prepared a men's version of my white shirt in my car. Hikigaya-kun, I'll have to trouble you to change into it later~"

"..."

Hikigaya turned his head away from Haruno and looked at Yukinoshita instead.

However…

Neither her being in Haruno's embrace nor the mention of matching outfits seemed to faze her. In fact, she even nodded in agreement.

Left with no choice, Hikigaya sighed and nodded as well.

Haruno beamed, still holding onto him as she led him toward her sleek blue sports car.

Yukinoshita exhaled softly before following behind them.

---

Upon reaching Haruno's car, she retrieved a neatly folded white dress shirt from the trunk and then turned to Hikigaya with a teasing smile.

"Alright, Hikigaya-kun, take off your shirt~"

"Uh… You want me to strip in public?" Hikigaya's reluctance was obvious.

"Hmm… That's true. Alright then, get in the car and change."

Without waiting for his response, Haruno opened the rear door and pulled him inside.

"!!!"

Seeing this, Yukinoshita immediately climbed in after them.

"Yukinon, what are you doing?"

"Making sure you don't do anything inappropriate."

"Sigh, don't you trust your dear sister? Yukinon, you're so cold..."

Haruno let out a dramatic sigh before shifting her gaze to Hikigaya, who was now trapped between them.

"Alright, Hikigaya-kun, go ahead~"

"You two…"

Hikigaya felt immense pressure.

The backseat of the sports car wasn't exactly spacious.

With both Haruno and Yukinoshita on either side of him, even the slightest movement risked making direct contact.

"Hehe, should I help you take it off~?"

"Huh?"

"Here, don't move~"

"Haruno!"

Watching her sister try to undress her boyfriend, Yukinoshita felt an inexplicable thrill—but quickly forced herself to stay calm.

"I'll do it!"

Hikigaya: "??"

Hikigaya: "!!"

---

A few minutes later.

Haruno was driving toward the mall.

Hikigaya and Yukinoshita sat in the backseat.

Hikigaya was now wearing the white dress shirt that matched Haruno's.

As she drove, Haruno smirked mischievously.

"Hikigaya-kun, have you been working out lately? Your physique is really impressive."

"Ahem… Yeah, I have been." Hikigaya answered casually.

"And you smell amazing, too. No wonder—fit guys are just naturally more attractive."

Haruno chuckled.

"Yukinon, you're really lucky~"

Hikigaya's face turned slightly red.

Yukinoshita's cheeks also warmed a little.

Still—

Despite her embarrassment, Yukinoshita couldn't help but notice something.

Hikigaya did have a unique scent.

A pleasant, intoxicating one.

[Hikigaya Hachiman's stamina has reached 100/100. His body now exudes a strong masculine scent.]

[The more mature a woman is, the more she'll be attracted to this scent, leading to obsession and infatuation.]

After hearing this explanation from the system, Yukinoshita suddenly understood.

A full stamina gauge meant her boyfriend was overflowing with vitality. And in reality, mature women were naturally drawn to energetic men…

So that's how it is.

Wait—hold on!

Haruno isn't exactly "mature" yet. She's only in her early twenties.

If that's the case, what about women in their thirties? Or married women…?

Yukinoshita's heart skipped a beat, suddenly feeling a sense of unease.

At this rate, wouldn't her boyfriend become some kind of natural seduction magnet for older women?

Looks like I'll have to be careful about letting his stamina hit the max in the future.

Otherwise, he might become… very dangerous.

Soon, the group arrived at a nearby shopping mall.

They picked a self-service photo booth meant for couples.

Haruno dragged Hikigaya inside.

Since only two people could fit comfortably, Yukinoshita had to wait outside.

Inside the booth—

Haruno leaned in closer to Hikigaya, pouting slightly.

"Hikigaya-kun, come on, move closer~ We're supposed to look like a couple! And smile a little, don't just stand there looking like a lost puppy."

"O-Okay…"

Hikigaya did his best to comply, shifting slightly closer.

But in the next moment—

His pupils shrank.

Haruno was unbuttoning her shirt.

"???"

Alarmed, Hikigaya quickly asked:

"What are you doing?!"

"The shirt's a bit tight. Just loosening it a little."

Haruno undid two buttons with a smirk.

Thankfully, it was only two. If she had gone for a third, things would've been… very different.

Even so—

The slight reveal of her fair skin was enough to make Hikigaya instinctively lower his gaze.

"Hehe, what do you think?"

"W-What do you mean?"

"You know what I mean~"

Seeing him play dumb, Haruno grinned and wrapped her arms around his.

"I just complimented your physique, so now it's your turn to compliment me~"

Hikigaya stiffened, struggling to find the right words.

"Uh… very… high quality?"

"High quality? Be more specific."

"Your legs are really fair and smooth…"

The words slipped out before he could stop himself.

Realizing what he just said, Hikigaya quickly averted his gaze from her legs.

Haruno's lips curled into a mischievous smile.

"Ohhh~ So Hikigaya-kun has been staring at my legs this whole time? My, my, how bold of you~"

"Huh?!"

Hikigaya's face turned even redder.

"No, I was just looking at the ground, and my eyes wandered by accident—"

"Hehe, it's fine~ If you want, I can even let you touch them~"

"You…"

Seeing Haruno's playful gaze, Hikigaya broke into a cold sweat and desperately looked toward the door for an escape.

Where was Yukinoshita when he needed her?!

Meanwhile—

Standing outside, Yukinoshita felt conflicted.

For some reason, this situation felt like she was standing guard while her boyfriend and "the other woman" were fooling around inside.

The mix of emotions was strange—part frustration, part excitement.

Sigh.

Whatever.

As long as she was earning system points, that was what mattered.

Of course—

As a girlfriend, she should at least pretend to be upset.

So, with a half-hearted tone, she called out:

"Hikigaya-kun, Sister, hurry up already."

…If anything, she secretly hoped Haruno would get a little rougher with him in the changing room.
