All the Heroines are my Ex-girlfriends

Chapter 1: Hello, My Ex-Girlfriend

At a private apartment near Shibuya Station, Tokyo.

The atmosphere was incredibly tense, as if the air had grown so heavy it was hard to breathe.

A real estate agent — with two years of experience in the business — was currently caught in a dilemma.

Today, she had received a request to rent a property.

The client was a breathtakingly beautiful young woman.

Following standard procedure, she took the client to view the apartment.

Along the way, the social atmosphere remained polite and formal.

That was until the stunning young woman stepped into the apartment and locked eyes with the landlord.

The air seemed to freeze instantly.

"Do you two know each other?" the real estate agent wiped the sweat from her forehead and cautiously asked.

That question finally shattered the suffocating silence.

The stagnant scene seemed to reboot itself.

The landlord set aside the contract in his hand and stood up.

"We do know each other," he said, accompanied by a faint smile.

The real estate agent felt that their relationship was far from just an acquaintance.

However, in an effort to close the deal and earn a generous commission,

the dedicated agent summoned all her courage and said:

"That's wonderful! If you two know each other, this will make things much more convenient. We can sit down and discuss the details of the contract..."

As she spoke, the agent forced a couple of awkward chuckles.

But before she could finish her sentence,

the beautiful woman—the prospective tenant—immediately interrupted:

"There's no need. Show me another place."

Her words were brief, her tone decisive.

The coldness embedded in them felt like the biting chill of a winter wind, almost sharp enough to sting the skin.

This, despite it being late spring, with warm and pleasant weather.

Even so, the real estate agent in the apartment couldn't help but shiver slightly, shrinking her neck a bit.

However, the landlord remained unaffected, his faint smile unwavering.

"Kasumigaoka-senpai is as decisive as ever."

"Tch!"

A dissatisfied click of the tongue echoed through the room, blending with the rhythmic clatter of shoes on the wooden floor.

Kasumigaoka-senpai, or more formally, Kasumigaoka Utaha.

This stunning young woman, her long legs accentuated by skin-tight black stockings, was trembling slightly.

Her black leather shoes tapped repeatedly against the wooden floor, producing a continuous clack-clack.

Anyone with a basic understanding of Kasumigaoka Utaha would know:

This was a small habit of hers, displayed whenever she was "in a bad mood" or "feeling uneasy."

However, compared to the deliberate way she fended off unfamiliar boys who approached her,

right now, Kasumigaoka Utaha was clearly flustered.

In a way, the landlord's ability to throw her off balance with just one sentence

could almost be considered a kind of talent.

After all, if Kasumigaoka Utaha were truly as decisive as he claimed,

she wouldn't have been so visibly shaken upon seeing him again.

Compared to discarding her meticulously crafted light novel drafts,

when it came to matters of the heart, Kasumigaoka Utaha had never been decisive.

In fact, she was far more hesitant and uncertain in love than most girls.

Crossing her arms over her chest, the white school uniform shirt she wore puffed slightly, outlining a prominent curve,

a trace of chilly air escaping with her movement.

"Speaking of decisiveness, who could possibly be more decisive than you? Isn't that right, ex-boyfriend-kun?"

The real estate agent immediately fell silent.

Though she had somewhat guessed as much earlier, now it was finally confirmed.

As expected, this tension in the air was the unmistakable flavor of ex-lovers unexpectedly crossing paths.

To be honest, was it possible that a goddess-like beauty such as this could also feel indignant over a breakup?

The real estate agent discreetly glanced at the landlord.

Just then, a warm summer breeze brushed past the clouds outside, allowing sunlight to stream into the room through the window behind him.

Under the pale morning glow, his disheveled hair swayed gently in the breeze.

His jade-like fair skin shimmered in the sunlight, his brows like a sword and eyes gleamed like stars—an unearthly, rare treasure.

The real estate agent found herself unable to look away.

Ah, so he was a stunningly handsome young man, on par with, or even surpassing her beauty.

Well, that explained everything.

Realizing this, she had the sudden urge to bite her handkerchief.

Youth, love... it all belonged to you Riajuu types.

As if that wasn't enough,

you even have the nerve to make life difficult for a working-class soul like me!

"So annoying! The Riajuu should explode!!!"

Meanwhile, the landlord—whom Kasumigaoka Utaha had just jabbed at with her words—seemed completely unbothered.

In fact, he even appeared more cheerful, his grin widening.

"Hello there, my ex-girlfriends!"

Kasumigaoka Utaha's elegant brows twitched slightly, furrowing into a frown.

"Tch!"

Clicking her tongue once more, she turned away, refusing to look at him any longer. Her gaze shifted to the real estate agent instead.

"I want another apartment."

Her words carried an icy finality, as if they could freeze everything in the room.

The real estate agent lowered her head slightly, avoiding Kasumigaoka Utaha's piercing stare.

"Kuhum..." Clearing her throat softly, the agent spoke in a low voice:

"Apologies, Kasumigaoka-san, but at the moment, this may be the only apartment that meets your requirements."

Summoning all her courage to say this, she immediately felt the surrounding atmosphere grow even colder.

Hastily, she added:

"You see, Kasumigaoka-san, this is the Shibuya area. Private apartments for rent here are extremely rare…"

After all, this was Tokyo—specifically, a prime location near Shibuya Station.

High population density, sky-high property prices, and scarce housing supply made finding a suitable place entirely unsurprising.

Kasumigaoka Utaha wasn't an unreasonable person, so she quickly accepted this reality.

However, the steady clack-clack of her shoes against the wooden floor resumed.

Having come to terms with the situation,

she now faced a difficult choice.

Was it more intolerable to rent her ex-boyfriend's apartment?

Or would it be worse to settle for a place farther from Toyosaki Academy,

or one that wasn't a private apartment and came with subpar conditions?

Kasumigaoka Utaha was a night owl, so minimizing her commute time was essential.

Additionally, given her tendency to lose track of time while writing light novels, she strongly preferred independent apartments.

Truth be told, this apartment was perfect for her needs.

But…

What about the ex-boyfriend?

As she mulled over her dilemma, Kasumigaoka Utaha's gaze involuntarily drifted toward the landlord.

Seeing the smile on his face,

an inexplicable anger flared up from deep within her.

Was that… provocation?

It was definitely provocation!

"I'll take this apartment!"

Kasumigaoka Utaha gritted her teeth as she made her decision.
