All the Heroines are my Ex-girlfriends

The sound of a door unlocking echoed at the entrance.

Shijo Maki, who had been feeling unsettled, immediately calmed down upon hearing that sound.

It felt like she was being forced to maintain her composure.

Though, one might wonder what Shijo Maki's "forced composure" button actually looked like.

Shinomiya Kaguya and Suou Yuki entered one after the other.

Shijo Maki turned her head and locked eyes with Shinomiya Kaguya.

"Good evening, Oba-sama."

At those words, the corner of Shinomiya Kaguya's mouth twitched slightly.

( •̀⤙•́ )

Then, with a somewhat helpless expression, she replied:

"Maki-san, could you not call me Oba-sama?"

"We're clearly the same age."

Shijo Maki smoothly stood up, clasped her hands in front of her chest, and gave a polite smile.

"In terms of family relations, it's correct, so there's no helping it."

Her tone was distant, businesslike, with a hint of provocation.

"Besides, my family teaches us to respect the elderly."

( ͡º ꒳ ͡º)

A vein popped on Shinomiya Kaguya's forehead.

<(ꐦㅍ _ㅍ)>

Although "Ice Princess Kaguya" wasn't overly concerned with how others perceived her, she was still a high school girl.

Being implicitly called a "hag" like that—of course, it was irritating.

"Ah, that's right. It's only natural for branch families to respect the main family."

Shijo Maki lightly brushed her hair, intending to strike a cool pose.

But as soon as she ran her fingers through it, she realized her hair was a little messy.

At that moment, she remembered that Yukima Azuma had brought her back here.

And that she had slept soundly.

With that, she lost interest in arguing with Shinomiya Kaguya.

"Now that scary Oba-sama is back, I'll be going."

With that, Shijo Maki headed toward the door.

She wanted to go back and sort out her feelings.

Her feelings about Yukima Azuma.

As Shijo Maki stepped out, Shinomiya Kaguya could only let out a helpless sigh.

"That girl is really not cute at all."

(˶˃⤙˂˶)

Hearing that, Shijo Maki, who hadn't fully closed the door, felt her heart skip a beat.

She took half a step back, leaned in halfway, and grinned.

"But you know, Azuma-kun just called me cute!"

(≖⩊≖)

With that, she dashed away, slamming the door behind her.

Like a child who had won and immediately ran off.

Shinomiya Kaguya, upon hearing that, completely lost her composure.

"Eh? You called her cute? Yukima-san!"

"May I ask, what exactly do you like about her? Is it her face?"

"She even calls you by your first name!"

(｡•̀ ⤙ •́ ｡ꐦ) !!!

It wasn't clear what she was jealous of, but she was definitely jealous.

It felt like she had lost something.

And that kind of feeling, Shinomiya Kaguya could not tolerate—not even a little.

"The cute part is that she resembles you a little, Shinomiya——Kaguya!"

(ᵕ—ᴗ—)

Yukima Azuma responded immediately.

There had already been enough chaos these past few days; it was best to keep things peaceful.

Upon hearing that answer, Shinomiya Kaguya's heart was instantly filled with satisfaction.

At the same time, a faint blush quietly spread across her fair cheeks.

(„ᵕᴗᵕ„)

Suou Yuki, watching from behind, silently praised, "Sasuga Onii-chan-sama sugoi!"

ദ്ദി ˉ͈̀꒳ˉ͈́ )✧

Her Onii-sama truly had the skills of a harem protagonist.

It seemed that even if he were thrown into the so-called legendary "Shurafield of Love," Onii-sama would still handle it with ease.

...

Hawaii, Day Four.

Today was a beach day.

The study portion of the Hawaii trip was essentially complete.

Now came the travel portion.

Yukima Azuma changed into a pair of swim trunks, threw on a beach jacket, and left his room.

Just at That Moment, Suou Yuki Also Stepped Out

At this moment, she was wearing the light purple one-piece swimsuit that Yukima Azuma had chosen for her.

Although it wasn't too revealing, one had to admit—the shade of purple was truly captivating.

The swimsuit hugged the alluring curves of the girl's body, creating a half-concealed, half-revealed effect that stimulated the imagination and made it impossible not to feel a surge of excitement.

Seeing Yukima Azuma looking at her, Suou Yuki spun around on the spot.

"Onii-sama, do I look beautiful?"

(✿◡‿◡)

"Umu, my taste in picking outfits is indeed excellent."

"Eh? So it's just the swimsuit that looks good? Yuki isn't beautiful?"

( ,,⩌'︿'⩌,,)

"I was talking about Yuki. I have a great eye when it comes to choosing outfits for Yuki."

As soon as Yukima Azuma finished speaking, Suou Yuki was stunned for a moment before she immediately beamed with a radiant smile.

(✿≧ᴗ≦)

After laughing, Suou Yuki's gaze suddenly became glued to Yukima Azuma.

With a physical stat of 8, Yukima Azuma not only had strength, endurance, and agility far surpassing that of ordinary people but also a body that had reached near perfection.

The ideal "looks slim with clothes on, muscular when shirtless" physique.

Suou Yuki's eyes lingered on the young man's abs, finding it hard to look away.

"Yuki-neesan, ecchi~." Yukima Azuma teased.

(˵ ¬ᴗ¬˵)

Hearing that, Suou Yuki immediately smirked mischievously. "Ehehe, boy-ya~, let Onee-san have a feel~!"

( ͜ₒ ㅅ ͜ ₒ)ლ(´ڡ`ლ)

Saying that, she lunged forward, lifted Yukima Azuma's beach jacket, and reached out to touch him.

"Young boy~! Feels amazing."

Suou Yuki was practically drooling, looking like a middle-aged man harassing a high school girl.

Just then, Shinomiya Kaguya also stepped out of her room.

Suou Yuki immediately let go.

She quickly jumped to the side and started whistling guiltily.

Shinomiya Kaguya's swimsuit was a fiery red bikini, matching the color of her eyes.

For an ordinary girl, this color might seem a bit too bold, but for Shinomiya Kaguya, it wasn't.

Her aura was more than enough to carry such an audacious red, making it only serve to enhance her charm even further.

Seeing Yukima Azuma looking at her, Kaguya felt a bit shy and placed both hands in front of her.

"President Kaguya, that suits you very well!"

ദ്ദി(˵ •̀ ᴗ - ˵ ) ✧

Yukima Azuma gave her a thumbs-up in admiration.

Hearing that, Shinomiya Kaguya smiled in satisfaction.

She raised her left hand to her cheek, trying to maintain her composure, and then modestly replied.

"Thank you, Azuma-kun."

(>/////<)

"Let's go! To the beach! Run!"

Fujiwara Chika burst out of her room with boundless energy.

The girl, whose figure was no less impressive than Suou Yuki's, was not only wearing a swimsuit but also had a loose jacket draped over her.

Shinomiya Kaguya's gaze unconsciously landed on Fujiwara Chika's chest.

Even with the jacket covering it, its overwhelming presence was undeniable.

Then, she glanced at Suou Yuki.

And quietly closed her eyes.

Now that she thought about it, both Suou Yuki and Shinomiya Kaguya were carrying zip-up jackets.

As they reached the door, both of them put them on and zipped them up all the way to their necks.

Thus, even the slightest trace of their swimsuits was nowhere to be seen.

…

Upon arriving at the communal dining area, the group immediately spotted Shijo Maki.

Yukima Azuma's gaze swept over her eyes.

The dark circles had disappeared, and the brilliant purple in her eyes was no longer laced with red veins.

It seemed that she had rested well last night.

In fact, even Shijo Maki hadn't expected this.

Last night, she had actually slept soundly.

At first, she thought she would suffer from insomnia again.

But unexpectedly, after lying down and thinking about Yukima Azuma, she quickly drifted into slumber this time…

Like Kaguya and Yuki, Shijo Maki was also wearing a long jacket.

As everyone approached, her gaze landed on Shinomiya Kaguya.

"Good morning, Oba-sama."

(✿ᴗ͈ˬᴗ͈)⁾⁾

Shijo Maki greeted with a smile.

Shinomiya Kaguya merely nodded indifferently, showing no particular reaction.

"Good morning, Maki-san."

Such a calm response made Shijo Maki a little suspicious.

Did Oba-sama eat something strange today? Why is she being so easygoing?

How odd.

...

After Breakfast

The group of Shuchiin students headed out to the beach together.

It was a private beach.

Every day, there were designated staff members responsible for cleaning and maintaining its pristine condition.

One could say that aside from the sand itself, there were hardly any impurities.

The sunlight reflected off the shimmering ocean surface.

Fujiwara Chika was the first to let out a joyful cheer before dashing straight into the water.

✧｡٩(ˊᗜˋ )و✧*｡

Waves rolled up in layers, gently embracing her bare feet.

Although it was December, the weather here still felt like summer, with the bright sun high in the sky.

Suou Yuki picked out a sun umbrella.

Under its shade, she unfolded a lounge chair.

Then, she winked at Yukima Azuma.

Just from her eyes alone, he could tell this girl was up to something again.

"Azuma-kun, come help Onee-san apply sunscreen~"

(˵ •̀ ᴗ - ˵ ) ✧

Suou Yuki grinned mischievously, still fully immersed in her Onee-san act, even throwing in a suggestive wink.

"This is an essential activity when going to the beach!"

As she spoke, she lay face-down on the lounge chair.

Her posture was utterly relaxed, as if she was leaving everything up to him.

Yukima Azuma poked Suou Yuki on the forehead.

"Is that otaku brain of yours constantly filled with hentai thoughts?"

"Ehhh?" Suou Yuki turned her head. "You're not coming? This is a special privilege, you know!"

At that moment, Shinomiya Kaguya took out a bottle of premium sunscreen from her bag.

"Suou-san, let me help you instead."

Hearing this, the corners of Suou Yuki's mouth stiffened.

Yukima Azuma almost couldn't hold back his laughter.

In reality, Suou Yuki had already applied sunscreen before leaving the room.

At most, she only needed a slight touch-up on the back of her neck.

Now that Shinomiya Kaguya had interrupted and completely ruined her plan, she could only accept the outcome and go through the motions.

However, there was one girl who actually hadn't applied sunscreen.

Yukima Azuma's gaze shifted toward Shijo Maki, who was huddled under a sun umbrella, looking as if she wanted to say something but hesitated.

He couldn't help but think:

Aren't you supposed to be a genius?

Why are you making such a foolish mistake?

You're in Hawaii, and you didn't apply sunscreen?

At this rate, by the time we head back, Shijo Maki's skin tone will have shifted by at least four to five shades.

But for her to ask Shinomiya Kaguya for help...

She'd probably rather suffer a sunburn.

Yukima Azuma took a bottle of sunscreen from Suou Yuki's bag and handed it to Shijo Maki.

"Apply it yourself first. If there are any spots you can't reach, let me know."

Shijo Maki let out a soft "Mm."

It sounded no different from the faint squeak of a small animal.

Seeing this scene, Suou Yuki raised her hand and rubbed her forehead.

"So this is what they mean by 'too smart for their own good'..."

(˶˃⤙˂˶)
